John, thanks man! i was going to find a mod to do that for us tomorrow, but it seems you've already been notified! haha looks like i'm a step behind on this whole FAQ thing. meant to start it, someone else did, meant to find a mod to sticky it, someone else did. :rolleyes: oh well! as long as it's here and it's stickied, who cares who did it? keep contributing, people! :D

J SPEC SilEighty - S13_Iketani

When you get the info in here that you want, I can split the thread into a new one and pick and choose the posts that you want to be in the FAQ, then lock it for you.

Make it something like the car modeling forum has...
Car Modeling Forum FAQ (http://www.automotiveforums.com/vbulletin/t63623.html)

You can still leave a "FAQ suggestion" thread open so other's can add their thoughts comments whatever.

Feel free to pm or email me with anything you need. I will do my best to make it look nice for you.

John - thanks alot man! you're really being a big help to us trying to get this little guy off the ground. so far i think we can leave it, i don't think we yet have enough to break it in 2. we'll leave it be for now and hope that some more people will contribute (seems so far it's only me and J Spec). when it gets to the point, then one of us will let you know! thanks again, my friend!

yeah John you've been a big help so far. Like S13_Iketani said, we will just use this thread for awhile to post info and then we can pull out all the good stuff and make it into a permanent FAQ. Once again, Thanks for all your help :)

ok now someone post the diffrence between apexi n1 exhaust and apexi n1 dual exhaust before i shoot the new bunch of newbies

why don't you take some intiative and find it yourself and post it up here? we're not here to do all the work.

something that I haven't looked for as of yet that I think would be nice in the faq section is links to downloadable shop manuals on both the domestic and foreign versions of the car. so far everything that has currently been posted looks good and I will see what I can do in regards to finding pdf manuals or something to that nature.

i would actually like to know what the emissions are on an SR20DET are like. could you pass Cali emission laws with this engine even though i live in Toronto and not Cali. Cali is lower so i would think it would be passable here. i dont think i've seen any sites that have actually brought up a Q&A for that.

N1-The single canister APEX Exhuast. Loud and buzzy sound.

N1 Dual-See above with 2 canisters.

Just make your self a straghit pipe, or gut the cat out and you should be fine.

thanx for that info.
how much hp can you get out of a KA-T? like push it to its max without blowing it?

Derek - it CAN be done. Dart Izumi won a round of last year's D1 series with a 2JZ powered S14.

N1 sound can vary depending on how you've tuned your car. it's not always loud and buzzy.

SR will not pass Drive Clean in Ontario.

and cutting the cat out of your exhaust is illegal and not a good idea unless your car is strictly for track use.


I thought dart had a 1JZ.....The difference is there....no matter he has a HUGE budget


BTW If SR cant pass DriveClean, how come ppl here have it....I think it can pass w.a stock exhuast....Our regumalations arent as strict as Cali

not sure. i haven't seen to many SR's around here yet, and if i did, i didn't hear if it passed or not. maybe some of them only use it for track. i don't know.

One more thing I felt I had to add....

Drifting is not Initial D, or D1 or Video Option or Super Street...

You will spin, you will crash, you will blow something..It's a fact of life..if you havent spun out, theres something wrong....This is what will keep the riceboys out...once they crash and blow theyre 6k paintjob, they wont wanna do it....It's hard, but if you perservere, you will get good

You know what I meant...North American drifting isnt.

Also, to any trolls who disagree with my sig. Plz see the thread Dorkfin, soon to be titled "Ricer 0wnage Thread" on why I hate ricky chu and his car.

Thats alright-dont neeed more people hogging our S13 conversions :rolleyes:

This FAQ has turned out nicely...seems only you, me and Brian have contributed

Word, the only thing those "Drift" Bumper are good for is when you need a POS bumper for the snow, or at the track...


I feel so bad for GarageMak.....

SR requires alot more maitenece and will be a bitch if something is dying, but in the end, is great.

If you have the cash, get a spare engine, or get one once youve saved up. It will save the hassle of having to wait for parts when something blows.

You do realize that the SR20 is in many USDM vehicles and is pretty familiar stuff to nissan mechanics? If your engine wasnt a stock SR20, you wouldnt take it to the dealer anyway.

I just argue with people when I think they are wrong. Sometimes I can prove to them why they're wrong, sometimes they can prove to me why they're right (and why im wrong). Its all objective arguing...dont confuse it with flame.

No I realzie that. I respect you too b.c your not like "your a fag, you dont know shit etc."

I guess most SR20 crap is the same, but the dealers around here cant tell their ass from their elbow..

Theres a mechanic who takes care of a Hennesy Viper and a bunch of rally preped Subarus....I'd go to him....

plus, there ARE differences between the FWD and RWD SR20's...

your new sig, copy and paiste this:




THE PLAN:
Learn about brakes and their associated parts before going faster, you'll want brakes before u smash into something with that nice body kit, better brakes might have avoided the situation. LOL

I'll post something when I find the magazine with the article about the brake conversion.

If you want to face our wrath, DONT ask questions like thishttp://www.automotiveforums.com/vbulletin/t91065.html

Hehe, looks like he got the link backwards. Just do a copy and paste to get there. It is a pretty good site. I am now however depressed after learning what the rest of the world had that we didn't get here in the US.

y0 dat FAQ is tYtE, ZilViaZ rox0r...

Wheres this S15 2000 you own?

Most of us can afford RB swaps...:(

BTW you have a T51-SPL or a T51 Kai

HKS T51R KAI (or at least thats what it says on the compressor housing)
i couldnt find a SPL that was cheap enough, but this works

for those of you who dont know the difference go to http://www.rotaryextreme.com/hks.html about halfway down the page youll notice the turbo specs the difference between kai and spl is the compressor inducer and compressor major


HKS T51R KAI - 800 PS Output

COMPRESSOR:
-Wheel- 56 Trim - 70.3 Inducer / 94.0 Major
-Housing- 100 Inlet / 80 Outlet
TURBINE:
-Wheel- 76 Trim - 82.0 Major / 71.4 Exducer
-Housing- V-Band inlet / V-Band 115.5 mm outlet - 1.00 A/R



HKS T51R SPL - 1000 PS Output

COMPRESSOR:
-Wheel- 56 Trim - 76.5 Inducer/ 102.2 Major
-Housing- 100 Inlet / 80 Outlet
TURBINE:
-Wheel- 76 Trim - 82.0 Major / 71.4 Exducer
-Housing- V-Band inlet / V-Band 115.5 mm outlet - 1.00 A/R

Hmmm....this is very insteresting. So how much does the whole RB25DET swap cost?

Or you can be a big baller rich kid and go RB2X with T7X or T8X

I know of someone with an R31 Skyline(yes they made them) who has a T88 RB26(or it could be an 2 RX6 turbos...either way its a big ass turbo)

That car is supposedly the fastest car in the Island of Okinawa..

WOW a 50HP loss.You still only have 448HP left.LOL:eek: :flipa: :hehehe:

realnissan.com is a great site, thanks for recommending that. i think i'll stick with the ka and hope to turbo charge it by next summer. The sr20det vs ka-t question reminds me of a point i always argued with hondas. you could be the cool "jdm" guy with you b16b or b18c5 but an ls-turbo set up is still better. also the FAQ page is great, you guys answered alot of questions i had. i hope that i can post pics of my 92 coupe on here soon (it still needs brakes and a hood, but what do you expect for 1200$. starts right up tho, and only has 80k miles on it) hopefully this car will help me beat a rich kid and the audi his daddy bought him. by the way do any of you race or run solo 2 in the PA/NJ/NY area?

Good ananlogy.

Im glad the FAQ helped you.

so this is a "suggestion box" type dealy for the FAQ. if there's anything you think needs to be in there, then post up a suggestion here and we'll try and get it in there.

btw, don't worry if some of the posts in this thread don't relate to each other/don't make sense. all i did was split the FAQ into 2 threads, and took out all the junk that didn't matter. so some of it doesn't "flow" nicely.:)

heres a suggestion...

brian, ya know i love ya brother, but EASE UP!!

i know you only wanna be good at your job, but you gotta give us some slack. if every cop was as uptight about the rules as you are, we'd all be getting tickets for being 3 miles over the limit. ive never seen a mod delete as many posts as you have this last month.

im not tryin to diss you man, but i cant be the only one thinkin this.....

:werd:

this really has nothing to do with the FAQ...you could have PM'd me if you had any problems. but anyways, the only reason i deleted all those posts from that thread last night was because they were off-topic and had nothing to do with that thread. that's the only reason. don't give me guff for doing my job man. if i don't do it, someone else will.

my bad, i read "suggestion box"...

i aint tryin to "guff"ya man. like i said, i aint tryin to diss you at all.

but about the whole ot thing, i think you could just let that be. i mean, its just fun and games.

other than that, youve been doing a great job as a mod and thing have been going alot smoother because of things youve done. props for keeping the boards clean. but remember man, no one likes a neat freak

:biggrin:

hehe i know. i'm trying to do my best, but remember that i'm new to this whole mod thing, so my first month or so might be sketchy until i get comfortable with the position.

like i said, the only reason i removed all the posts from that thread the other night were because it was an argument that got resolved, so the posts didn't need to be around any more. my and the other guy resolved our differences. plus, people were reading the argument posts and taking sides, which i also didn't want to happen. and of course we were filling up someone elses question thread with needless arguing and junk. that's all!

sall good sall good...:D

dont sweat bro, your doing awesome.

could i upgrade the turbo on a SR20DET or would it just be pointless?? cause i was looking at increasing my horsepower to about 250 but i saw for about 500 more u could just get a better engine at http://www.srswap.com/
Should i just go for the better engine or upgrade the turbo? Also of the websites posted in the faqs which one would u say is the most reliable but least expensive??? Thx:bigthumb:

rb powered car is more worth it... instant 12's.

So which would you consider? KA-T or SR-T? Or RB25DET?

Yeah... this was from "240SX FAQ"...

Here is my first (set of) question(s): What should I look for in an 91-93 S13 Coupe 5-speed. Are there common problems that occur on these cars, bad trannies, clutches, electronics, etc? Are there specific options so that I will know if it is an SE or "base" trim? Are there any other trims beside the SE and the base trims? Out of the 91-93 cars, is any year better than any other?

Second (set of) question(s): What are some the unexpected costs of a SR20 swap? I dont plan to immidiately do aftermarket improvements so I'm talk about any hidden costs with the swap. I know you have to get an extended wairing harness, but what else should I expect that I am not now expecting?

Thanks for the help and I hope you use my questions.

i got a question duno if it has ben asked i search could find any thing can you put an rb26 head on to an rb25 block ,i heard is better and flows more ?:confused:

thanks

Yeah ive heard the head swap is possible a car on meggala.com supposedly had it.

thanks, i went there and found this on one of the gtr forum links :biggrin:

"Yes it will fit straight on. The Rb26 uses 12mm head bolts, the RB25 uses 10mm head bolts, you could use either."

"RB26 head is same casting with same sized ports, valves and combustion chambers. There is no power advantage in doing the swap."

duno about the power advantages but i heard that it flows more then rb25 head is that true ?

when and where did you start drifting, just late night curvy roads or are there drifting clinics anywhere? i figured suggestion box would be best for this newbie question.

try the "drifting" forum under the "Racing" subsection for stuff like this. :smile:

If meggala said it, prbably its true..he knows his shit

Drifting forum is a waste of time

how about an sr20det install faq. a VERY detailed one. i know you can always search around and shit, but since we ARE making a faq, why doesnt someone make a good install faq? :bigthumb: that will prevent this question from popping up every other day in the forums. :loser:

1996 Coupe 240sx - 5000 dollars with cover charge tax .. cause it is at a dealership. In good condition 139000miles.
1992 Fastback 240sx - 3500 dollars in GREAT condition. 131000 miles

which one? i cant decide.

There was an issue of "Turbo Imports" or one such magazine (I'll findo ut which) that said that the KA block would blow (between cyls 2 and 3, if I remember correctly) if fed more than 10 lbs of boost without some reinforcement. Can this be substantiated/denied?

It came from an article about a guy tha hit either 400 or 500 whp with a KA-T.

It was SCC, the issue where they built the turbo silvia for 3k. The guy went through 3 KA blocks while turboing. Upon reviewing the article it was mostly Jim Wolfe's fault for not putting in fuel management, but the engine still blew chunks into the TC. -Moral- Fuel management critical when doing a KA-T project.

Alright, I've read through the stickies, and damn that took a while.

Anyways, I'm hoping I didn't overlook something you already answered, but this is a slightly unique question.

Basically, I'm a poor college student, who is essentially considering buying a 89-93 240SX. They're pretty cheap, and I hear insurance isn't too bad for them. But I was thinking about buying a 240 for 2k (there's an abundance over here) and getting the engine swap done, my friend just got his done for 5k. Anyways, what are your guys' thoughts? I'm honestly not looking for anything really fast as it would be a daily driver, but I would like 200HP+.

Also, I don't know how to drive stick yet, so I was thinking that I could learn on the 240 before the swap, as a new tranny would be included.

I'm also open to other cars, so if anyone has suggestions in this field, feel free to list em.

Well thanks for any and all help.

-Rob

Dude I hate to piss on your parade, but if your poor, the 240SX aint for you.

Lotsa stuff breaks, the swap is expensive, and parts are.

If you really want a 240 with 200whp, go for a KA-T. You do your own kit for like 1grand, if you use a turbo from a junkyard car, a TIAL external wastegate, REVHARD manifold, and peice together your own lines, returns etc.

So, you will have 200whp for 3000 instead of 7000.

if you want an SR, then get an SR. just because a KA-T is cheaper doesn't mean it's the do all and end all. i respect KA-T's and would definitley build one, but i am and always have been an SR freak so i'm sticking with what i've always wanted, even if it's more expensive.

I wish I had the answers:

I want to buy a used 240SX. Are there any pitfalls or common problems I should look out for on these cars?

What is HICAS, and how do I know if I have it?

When is HICAS good, and when is it bad?

I want to put a 240SX on my bookshelf. What 240SX scale models are available?

(request for faq)

i was wondering if you could add images to the question, what are the differences between the models? (page 1 of the faq)

like pics of a stock usdm s13 coupe, s13 hatch, s14 oval eyes, s14 shark eyes, all jdm differences, and where 180sx fits in all of this

i think this would be helpful to n00bs like myself, i would do it, but i dont wanna make a mistake and give out misinformation, thanks in advance

... first post, woohoo...

here you are. (http://srswap.com/faq.htm)

I have a DVD that shows the COMPLETE install of an SR20, plus other boltons and crap. Its $10 CDN, so $5USD. PM me for info.

just FYI, you prolly new this already but the N1 dual is the same as the regular only it boosts mid range power, this is easily found at apexi-usa.com,
and I was wondering if you could add a ball park figure on an rb25det swap w and w/o labor

I've been looking through engine choices for a 89' - 94' Nissan 240SX. I'm getting ready to do a Sileighty conversion and was wondering, what engine would be better and/or fit, a SR20DET, VG20DETT, CA18DET, KA24(possible turbocharging later), RB20DET, RB25DET, and RB26DETT. Also could you possibly list the PROS & CONS of the engines, and to give some more info, the car will be used for mainly street/drag racing and some drifting. What do yall think would be that best for my application, and what would fit and what wouldn't. Also any other engine suggestions would be nice. Thanks your time.

KA24DET, skip the sileighty conversion. You will thank me. BTW dont bother with drifting if your mainly focusing on drag.

i guess this is the place for this....ive pretty much been sold on the RB25DET swap into a 240 as the project car for me. but i have a few questions i havent seen answered yet. i read through the FAQ thread and a few others, but id really rather not go trudging through pages and pages of back history and such.

the RB25 is heavier than both the SR20 and the KA (if research proves correct) but not by much. would i be able to make up this difference by losing the AC components? (dont use them in current car anyway, wouldnt use them in this)

also, ive heard that if this done (granted i got all this info from a honda mech, so im not too sure how accurate it is) that the RB is actually preferable weight wise (not any heavier after the removal) and it and the tranny actually sit further back in the car, bringing it closer to a 50-50 weight ratio. is this true?

the reason i ask is id like a car that can handle with the best, but still has the go to put that occasional yuppie supra in its place every so often.

According to Cameron, the first documented person to perform the RB25 swap (www.night7racing.com), it is true that the weight ratio is more evened out with the RB25. And Supra's are not for just yuppies.

oh, sorry, i got the impression that you asked a question here, and it would get answered, either here, or in the actual FAQ thread.

thanks for the confirmation

hey everyone, i was wondering if there were some good general facts sites for the 240sx. i need to learn the bare basics of the 240sx so i was wondering if you knew of any.

Random stupid question.

i installed a cold air intake on my 1992 240sx and the rpm's wont go below 4,000 at idle. any insite on how to reset the sensor so it wont think the engine is getting way too much air? thanks.

JOn

Ok I've looked and looked on the Newbie Must Read threads and either I missed it or it is not there.

Has anyone tried a VG30DETT in a 240 SX? I know it is for a 300Z but if a Skyline motor can fit with minor mods then shouldn't this? Would it be worth the time and effort? I just want a really fast car with loads of HP and a look I can live with.

Thanks for your time.

knuckle- The RB series go in alot easier than the VG30. This is due mainly because the RBs are straight 6's, whereas the VG30 is a V6(TT). It would take alot of money, time, and skillzzzz to make the VG fit.

I see... I ask because I want to try something new.. different.. I am willing to do the research if I could get some ideas. I want to build a project car starting this summer so I want to get all my ideas spun up first and try to head off as many of the foreseeable problems. Thanks for the input on the VG.
I will throw something at you again soon.

What are the max engine speeds of the ka and sr?
Anyone know a site that has side by side comparison's between the two engines stock? or with the ka being turbocharged with ~equal injectors/turbo/compression or what have you...
How much does a SR and KA weigh?
basicly just trying to see what paying 3000+ for the SR swap would actualy get me compared to the ka. atm only thing I can see is it being allot lighter..

oh yeah, and what are these cars called? the 240sx 180sx silvia... like what name do they all go by?(such as camaro and firebird both go by f-body) *this willl make doing searches allot easier for me.. :P

thanks.

Well in researching many cars and asking way too many questions, I was wondering how long just a stock KA24DE would last. MAybe with a few mods like intake and exhasut. Maybe there are a few other people wondering about this. The only cars I cab really afford have 100k, and I know the engines will last longer, but how much?

well i had mine running till 150,000 and then blew the engine cuz i forgot to add oil ( i thought i did) and preceeded to go 100mph down the highway and bam blew a whole the size of a baseball in my block. But now i have a junkyard engine with 160,000 miles and it runs good still.

what are body panels??

OK, not sure how often this thread is checked out, but I have been all through the FAQ, and wanted to post up a quick question, I havent finished searching all the threads in here yet, but I figured Id stick this up and see which yielded results first. I went to all the links posted for companies selling SR20DET's and RB25's and only found 1 company that was either in business, or still carried the RB25 package. Can anyone recommend a company that for sure carries the package? Thanks.

i dont know if this has been mentioned, but a good thing to add to the faq is legality issues (what is and isnt legal). And if possible list or do questions on whats legal on certain states. I know its illegal to do any swap in a 240 or turbocharge it in california. I guess this could help out a lot of newbies from getting into trouble.

Here is my deal...i'm really thinking about getting a 240sx...and like you can guess i'm going to get a SR20DET. But i was reading over the FAQ again and i'm not sure if i should get the SR20 or just turbo the KA. What i'll be doing with it is road race, highway, drag/light to light drag. But i know i'll do most of it highway racing then the 2nd most thing will be light to light drag. And also...most of all t daily driver. I like a little low end torque but i like it so at highier rpms i have alot of hp and torque. So what do you think would best fit me. If i could i would really not like to turbo the KA. But if that whats will work best for me then thats ok. So what do you think?

And i will not do the RB.

I've been searching around these forums lately as well as other places online. I have found very little information about the CA18DET engine. I know it fits in the 240 but how much power does it produce and how upgradeable is it. I know there is a famous drifter that uses one but I can't remember his name, its a red falken 240 it might be blue now though. Also, are these engines easily found or are they a rarity.

Thanks for helping a complete noobie.
Rob

ok, i read the entire FAQ's, very good job explaining basically everything u can about the SR20DET. But, i didn't see much on the RB's i wanted to drop the sr20det into my 89 240sx, also known as the s13 silvia, but anyways. Then i seen a post about the rb25det, and it made me doubt the capabilities of the SR. Not to mention the arm and the leg that they charge u for the SR20DET, but what i wanted to know was, what about the rb20det swap on my 89 240sx? should i go that way, or the rb25det, the specs that i seen on both according to the FAQ's was the sr20det = around 200-250, the rb25det = 280-300, what is ur advice, and can u post any other websites where i can find more info on the rb swap?

Thank you

OMG i see everybody has a damn question, and nobody is gonna answer mine :(

admin, PLZ ANSWER ME!!!!!! HELP

I've been searching around these forums lately as well as other places online. I have found very little information about the CA18DET engine. I know it fits in the 240 but how much power does it produce and how upgradeable is it. I know there is a famous drifter that uses one but I can't remember his name, its a red falken 240 it might be blue now though. Also, are these engines easily found or are they a rarity.

Thanks for helping a complete noobie.
Rob

I believe the ca18det has 175 hp and some people apparently prefer it because 1st it gets higher RPM's than the sr20det. High rpms are great for drifting. 2nd it's a little bit cheaper than the sr20 for the initial cost. The motors are pretty similar from my understanding. I believe the ca just has a shorter stroke. Just like any turbo motor, you can upgrade it, it just depends on how much money you have. You can pretty much do the same things to the ca as you can to the sr. It's not quite as popular of a swap though, so you may not find quite as much support.

ok, i read the entire FAQ's, very good job explaining basically everything u can about the SR20DET. But, i didn't see much on the RB's i wanted to drop the sr20det into my 89 240sx, also known as the s13 silvia, but anyways. Then i seen a post about the rb25det, and it made me doubt the capabilities of the SR. Not to mention the arm and the leg that they charge u for the SR20DET, but what i wanted to know was, what about the rb20det swap on my 89 240sx? should i go that way, or the rb25det, the specs that i seen on both according to the FAQ's was the sr20det = around 200-250, the rb25det = 280-300, what is ur advice, and can u post any other websites where i can find more info on the rb swap?

Thank you

Hey man, RB's are sweet, but don't doubt the sr20det. They can put out more power than you will ever need. There is also probably a lot more people that can help you out with the sr because more people have done it. The RB is going to require more custom fab work seing how they were never actually put in the s13. The SR however was, so the swap is a lot easier. If you think the sr's are expensive try pricing a RB25 or 26dett. Now that is expensive. They do have the capability of puting out more power in the end, but unless you need more than 400-500 hp you should be fine with the sr. If you need an engine, try www.zerolift.com They are in Ohio, that's not to far from you. They have pretty good prices too, I think it's like $1800 for an sr with the harness. I think they can put it in for you too. I know that unstablehybrids.com did RB swaps, but they went out of buisness. Whatever you do, good luck

thank you for the help

wich would be quicker out of these two options

1) keep the stock motor and dorp forged pistons and a t3//t4 turbo

or

2) swap the SR20DET

choice one.

does the ka24 oil filter work on the rb26dett? i've heard rumors!

i think im gonna stay with my s12, the boxy style is crappy but I repainted my interior, and there is nothing that a little love and money can't solve, unless ur god and can do anything :)

does anybody know how I can install a bodykit on the s12, or also known as the 86 200sx. I have seen some with a lip, but I can't find anywhere where they sell them, any advice

what's the difference between a 89 and 91 s13 coupe beyond the engine? is it just the body? i want to know ALL of the minor differences b4 i buy one.

PS its so darn hard to find s13s w/ sunroof & stick in norcal!

a comprehensive list of what parts are interchangeable between s12/13/14/15 and all other nissans. Especially what parts swap into the S13. There is a new thread on that idea however I had hoped that you could post the most common and important ones on your FAQs page and/or add to the new thread called interchangeable parts

I hear about Tachs not working with rb swaps, I'm going to be droppin an rb25 in June, how can I make sure that it works and how can I get my MPH gauge to read higher, I have a feeling 115 won't be enough for my new engine

Will a 91'-94' J30 Subframe bolt onto my '90 240sx

How do I know what turbocharger is right for my engine?

Well each turbo flows a different amount of air at a certian boost pressure at a different efficiency. You can refer to your boost pressure as your pressure ratio. We'll use 7psi for now.
Pressure ratio: (7psig+14.7/14.7)=1.42

That is the number that is usually on the right of a compressor map. The number on the bottom is how much your engine will flow at a certian boost level. There are a few things you will need to know about your engine before you try to do this.

Engine size=146cid(KA24DE) or 122cid(SR20) 1liter=61.02 cubic inches.
Max engine speed=5000rpm
Maximum boost=7psig
Ambient temperature=80F
Barometric pressure=29 in. Hg
Start by converting your displacement to cubic feet

146cid/1728=0.084 cubic feet

or
122cid/1728=0.071 cubic feet

Now you have to calculate ideal volume flow of the engine

Ideal Volume Flow

=0.084 cu ft/revolution * 6000rpm/2 (these are supposed to be fractions

=273cfm

The 6000rpm is used because the power of the KA falls off after that. Use your maximum rpm for that number. Now you have to calculate actual engine flow. I'm using 80% efficiency but of course that can change with engine modifications. Some engines can acheve over 100% volumetric efficiency with tuned intakes and exhausts.

273cfm*.8=218.4cfm

Air doesn't enter the engine in standard conditions either. Air temp is affected by the turbocharger so density must be calculated and added into the equation.

Let the pressure ratio be r.

r=1.42
Y=.104

Ideal Temperature Rise=/\T ideal

/\T ideal=Y* (ambient tempF+460F)

/\T ideal=.104*(80F+460F)=56.16F

Add 460 to convert to absolute temp i.e. Rankine. That is how much the air temp would rise if this were a perfect world, but it is not. Now you use this to figure out how much the temperature will actually rise.

Actual Temperature Rise=/\T actual

/\T actual=/\T ideal/compressor efficiency

/\T actual=56.16F/0.65

/\T actual=86.4F

Now you can find out what temperature the air in your intake manifold will be.

Intake-Manifold Temperature=ambient temp+/\T actual
=80F+86.4F
=166.4F

Now you can find out your density ratio. This is the pressure ratio with temperature taken into consideration.


Density ratio

=Inlet Temperature/Outlet Temperature * Outlet pressure/Inlet pressure

=(80F+460F)/(166.4+460) * (13.8+29)/29

=540F/626.4F * 42.8/29 (these are supposed to be fractions)

=23112/18165.6

=1.27


So now, the actual compressor flow(engine flow) is

=Compressor inlet flow(engine flow) * Density ratio

=218.4cfm * 1.27

=277.3cfm

You can convert this number to lb/min if that is how the compressor map is set up by multiplying Compressor inlet flow by 0.069.

So the air flow in lb/min is 19.1lb/min

The compressor inlet flow is the number on the bottom of a compressor map


http://www.atpturbo.com/root/maps/images/gt30rcompress.gif


At a 1.47 pressure ratio and flowing 19.1lb/min, we should be in the 72% efficiency island. You shouldn't use a turbocharger if it is below 65% efficiency. Inside the 72% island is very good. But the higher the better. Get it?

I gathered most of this info from Turbochargers by Hugh MacInnes. So if my jibber-jabber isn't clear enough, read that. I did most of this biased for the KA24DE because I myself had a hard time trying to figure out what turbo to use. That is what I hear from most of the new guys wanting to turbo thier KA. These will easily convert over to SR use. This may be something for the Forced Induction forums but I feel it will be very useful to people in the 240sx forums as well. Do as you will with this post. Thanks.

Hey, I've recently just gotten into cars, namely the S13. I love the way the car looks, so sexy! And its got decent bang for the buck as well! So I've decided that I will probably get a 240SX and swap in the SR20 and convert the front into the S13 front.

Only thing is, I've never really been a 'hands on' kind of guy. I was always the kid who would go out and buy a slingshot rather then making it. However, upon doing some research, I've found that taking this approach to car tuning is very, VERY expensive. I've already found some people in my area that have an SR20 in there 240s, so I think they might be able to help me out in that regard.

However, what I wanna know is how hard is doing the S13 front conversion? I've already found a site that sells all the parts. Is there a guide or anything online on how to mount the various lights and body pieces? What tools you need? Wiring? I looked through the FAQ and this thread but didn't find much.

Sorry for this question, I'm sure alot of you are probably like " WTF is up with this dumb n00b?!" because from what I've gathered it should be easy. However, as stated, I've NEVER done really anything like this before in my life, and I wouldn't even know the first place to start to be honest with you. Hell, I don't even no what tools I would need.

I think the hardest thing I've ever taken apart befroe was a PS2 >_<

Ok well for the engine first u can get it and have it installed for around 4k total, this is for a s13 swap, 200hp about, which should come with custom air intake, front maount intercooler, and other goodies such as dyno tuning and such. most tuner shops should offer this, as for the body work, there is a couple ways u can go about it, mainly its the use of fiberglass which is fairly expensive and u dont really want to do ur own body work, for about 2k u can get s13 front end conversion wich comes with CF hood and front bumper usually,includes the lights and fenders etc., but i really wouldnt start my own work until u maybe had a little backround knowledge because for the main reason of the sr20 u have to do some custom work on it yourself, and if u do these things make sure to upgrade the head gasket cuz the head gasket u start with is paper.
How much are you looking to spend??

if i were running a rb25det in my s13 mainly for road racing/time attack would i need:1) z32 front and rear brakes, 2) just z32 front brakes, 3) some other hardcore big brake system.

If you were running road racing or time attack peroid, it would be a good idea to get Z32 front and rear brakes. If you haven't noticed, the 240 brakes are not that great.

iw as just asking if front AND rear brakes would be necessary for hardcore racing bcuz all of the kits i have seen for a reasonable price just have the front brakes. let me know if there is a good deal for a front and rear upgrade kit.

Yes. Brake upgrades should be on the top of your list if you plan on doing hard racing. Front and rear should be adressed. Z32 front and rear are probably going to be the least expensive upgrade unless you just get pads and rotors for the stock calipers. I don't road race(mostly highway runs and such) and I'm looking into brake upgrades pretty soon. Good luck.

my engine is dead and i want to swap in a sr20de. does anybody know places that sell s14 sr20de?

^^for the SR20DE sites check the faq at the very top w/ the RB swap stuff, theres answers




MY question is... the boostdesigns turbo kit stage 1 is what i've had my eye on for my project car this summer
Q1: Will the kit fit on the S13, or is it only for the S14 240? there are no year specifics on the site
Q2: How much psi can i push with stock injectors/pump
Q3:at what point will i need an FMU or ECU setup?
Q4: my friend has a Mitsubishi 14b turbo off his GVR-4, will the revhard manifold bolt to it and would this be better than buying the kit?
thanks

it can go on either, s14 or s13 from what i understand
if you go intercooled i bet you could get about 7psi, but why would you want to risk it (Stay with 5 until you upgrade injectors, etc)
you will already have an fmu if you buy the stage 1 kit (it comes with it) i would say you could get away with an fmu for about 6 psi
i really dought it would bolt right up, that would be a coincidence if it did, but you would be better off buying the kit, you're going to need the stuff in that kit anyways..

cool beanos thanks

1) It fits both.
2) Not much. I don't think they make wastegate springs that small.
3) As soon as you boost the engine. I listed all of the fuel upgrades options in that "Turbo questions" thread I believe. Fuel Management Units are too cheap not to use. Even 4:1 is better than nothing, but I would recommend a 6:1 for T3 sized compressors and an 8:1-10:1 for T4 sized compressors.
4) I believe Revhard only makes T4 flanged manifolds now. But a Mitsubishi turbo will not fit a Garret flange. Look into the Greddy manifold as it is flanged for a Mitsubishi turbo. Not sure if it is the same though.

Boostdesigns kits no longer come with a FMU.

ive just recently bought a 89' 240 and i need to replace the engine in it....what can i replace the stock motor with so i dont have to change the ecu and all that other bull-jive technical stuff....also whats the displacement and stuff like that?
sorry for the newbie questions..

ECU tuning comes into account with every engine.

sorry for the newbie questions..

uhhhhhhhhhh, this may seem a little overwhelming for you, but you can probably (and by probably i mean for sure) just replace the motor that you have in it now (ka24e) with another (ka24e) motor. they come in the years 89 and 90 after that they are all ka24De D = dual over head cams, but you wouldve know that if you wouldve actually read the FAQ. NOOB.
ka 24 (d) = dual over head cams e = electronic fuel injection
^ ^
engine 2.4L of displacement
series

you wont have to replace the ecu if you swap an engine for the same exact engine type.

This question may have been answered, but I cant find it. I'm planning on going with a late model 240 for my next car, and I was wondering which motor the KA or the SR, can be built to be a bit more powerfull up top. I prefer racing from a roll, so which would be better to fit that roll out?

Either.

Better question....

What are your goals?

Well, I'm not out looking for a massive power uber drag monster, I'd be fine with a low14, high 13.I'd like something that can really get up there and move, but also be a pretty good daily driver.I've heard of boosted cars being somewhat of an event to drive, and I'm not really looking for something like that. Nissan has really just now started to catch my eye, so I dont really know a whole bunch about their cars in general, other than the Skyline.

Either the SR or the KA can do that. Both will involve about the same amount of money. Both would make good daily drivers. I drive my KA-T every day. What do you mean being an event to drive? I always though for a street car, boost is the way to go.:dunno:

ok, i didn't find this in the FAQ or anything but..

i might be able to get a pretty good deal on an 5sp sr20det motorset locally, but right now, i'm auto. if i were to get this, what else would be required?

getting that would eliminate the big parts right, what else would i need besides the pedals?

www.srswap.com has a writeup on it, with a few pics to, check the SR install guide and about half way down they get to the auto-manual swap.

Just wanted to add, here are different 240sx owner manual for CA18DET, KA24E, KA24DE, S14 and some more.
