naturally aspirated and its potential

sup guys...juss wondering if u could give me some advice. im soon to be getting a 95+ 240sx. i think i want to go a differnt route than the ka24de(t) or the sr20det swap. im thinking of goin naturally aspirated. so heres the thing i was wondering if there were any makers of a quad throttle body for the ka24de. i've been searching all night and i can't find any. also i would probably get high compression pistons, new rods, cam, rebuild my engine, ect. how much hp gains do u think i can get goin NA? also is turbo a cheaper and easier alternative? wat eles will i need to know about NA engines? Is there an other major NA engine component other then individual throttle bodies and high compression pistons?

thanks for ur help

if yopu wnat over 300hp go turbo if you want less then 300 go n\a

i prefer turbo..

but thats just me :rolleyes:

you WILL be spending alot of money on this. the n/a route is hard as hell. a guy in my club is going this way and has dropped about 5g's into his car and he says he is only making about as much as a stock SR. maybe a little more but not much. he also said he should have done the swap.

ive spent 3500 and im running a flat 15.0, but mine's an auto

im thinking if its a stick i'd be running around 14.0. it's a lot cheaper than popping in an sr.

3500? an SR swap is the same price! ...and twice as fast

twice as fast as 14.0?? hehe sorry to say, you know absolutely nothing :biggrin2:

an sr runs 14.5 with a real good driver.

sorry, you must be a really sorry driver or hang out with really sorry drivers. 5 friends. all SRs. two ran a best of 13.8. the other three run 14.2. Last time I was at CMI, a kid in a stock s13 SR also ran a 13.8 Done three SR swaps. All cars smoke GT stangs and Z28 camaros

ok I'm looking for an estimated(or exact if possible) time for each of these set ups

KA24DE: add turbo, non-intercooled, manifold, ehaust, downpipe, intake

KA24DE: the above + intercooler and pipingg, BOV, wastegate, exhaust flange

SR20DET: exhaust, intake, downpipe, BOV

KA24DE: non-turbo, port and polish, pistons, cams, rods, exhaust, intake, downpipe

say they all have light weight flywheel with like a stage 2 clutch kit and a B&m short shifter and light weight tires and performance tires and abotu 1 1/2 drop with decent suspension(hopefully this gets rid of some variables)

also what about the 2 kits for the KA24DE they have here http://www.realnissan.com/faq.asp

what are you talking about

http://www.mrccfl.com/quartermile.html

2690 lbs

205hp (and that's a HIGH estimate.. most sr's have 190hp because of age and use)


also a pro stock driver took out a stock sr and ran a 14.5. i really don't know why you are making this up...... your friends must have short shifters and lightened flywheels. they are NOT stock

ok, more details ...when doing the swap, don't just take it and put it in. Obviously check for a motor that has good compression. If not, make it so. Clean clean clean. check all, or change if budget allows, vacuum lines. make sure no leak in pipes, and around stock intercooler. if everything is working right. e.g. clutch not fried, bad turbo, etc. 13.8 is attainable. 14.0-14.2 is more likely. I am telling you from experience. We tested at Sacramento raceway, so our elevations may be different from yours. Also, for the previous question, an SR swap shouldn't take more than three days. Two if you don't have to take the SR out of a clip. Easy swap. KA24de(t), I can't say, because I have not done any. My friends integra, which in my opinion is harder to work on, took only one day to put on his drag turbo kit. But depending on level of knowledge and experience, this obviously will vary (sometimes greatly!):iceslolan

Actually Sr20 swaps are only 2500 bucks and 3000 for the front clips so that leaves 1000 or 500 in mods which would easly take out his N/A Single Cam.

Also you are not going to shave off a second in the 1/4 mile time just because it is a manual maybe .4 seconds.

interesting you say that

everyone is telling me a stick is the ULMIGHTY GOD of the racing world. .4 sec aint that much.... i thought it was .4 too but a lot of people tell me it took off a full sec

LMAO 3500 to run 15

hehehe


if i spent 3500 i better be in the 13's

I ran 15.7 with a crappy exhuast, faulty clutch that was going out and bald tires


I figure put some low pros on it, the clutch was just changed

get the cold air intake, better exhuast, some headers, ported and polished i can get done for 200 on the head, or sometimes I see head withs high compression pistons for like 100-200 on ebay sometimes, and that leaves u wti a lot of money for misc mods wherever the fuk u want, u could even get some spray with that LMAO!

The only reason I would do an sr20det swap is because i have 150k miles

but even than, if im gonna spend that much money on a swap, ima just save up and do a 350chevy swap :-D VRRRROOOOOOOOOOM!

350 in a 240sx........ :spit:

hmmmm how about an old 327 or z28 302, that would be badass if you had to have a CSB. Getting a northstart to work would be badass, 300hp and that thing likes to rev, one of the best v8's I've abused.

if your gonna do something different, do something different...

so sick of hearing about 350's.... it isn't the end all engine and a 327 or a 302 will whip its ass and is a better engine for a road course.

Post your time slips...we have lots of liars on this board and can take nothing for face value :rolleyes:

a bone stock SR will run mid 14's. thats with stock exhaust etc. now, if you have a front mount intercooler, 3in. exhaust, boost controller, intake, and a new clutch......i've seen as low as 13.3. it was an s13 sr in an 89 240sx on stock tires.

nightwalker, when you say stock, how "stock" are you talking about?

hmm good ideas, i just know i want a V8

will a v8 chevy engine even FIT into a 240sx, also even if it did, wouldnt an engine that heavy put too much weight on the front therefore causing the car to lose traction in the rear. just wondering...

your probably going to have to do some massive mods to the frame.

that is ............ to make if fit, and i dont know what the effect of the weight will have.

j00 wanh NA powa?

Try carburated SOHC KA24

j00 wanh NA powa an be jDm tYt3 y0?!

Try INDIVIDUAL THROTTLEBODY SR20

if youre talking for straight drag racing....

auto + boost + high stall TC = ownage

for the twisties...its a different story though...

:iagree:

i'm completely rephrasing my thoughts of the n/a

i went to the track yesterday. let's just say, my car's speed is a COMPLETE JOKE. i really thought it was a lot faster. i would post my timeslip but... :headshake

naturally aspirated sucks people. get a turbo or engine swap

yep people like drag racing with automatic turbo cars.... one good point is you don't loose boost during shifts..... with modifications such as a higher stall TQ, shift kit, coolerS, fans on them... it can be great, it is more consistent, with modifications it will shift as fast as a manual ever could, and no human error ever...

The downfall is holding your gear or downshifting when you want to in corners.....

But you dont get the pssshhtt sounds lol

Actually .4 seconds is a lot of time in the Drag Racing world. Shave time off your ET is not an easy thing to do. I went the wrong way with going N/A Single Cam with my civic and my fastest time is still a 15.79. I am going to over to Nissan Turbo so when I put mods on I actually gain horsepower.

You didn't go the wrong way...You need to some real mods to the engine thats what.

You could only go so far with just bolt-ons..

Originally posted by Dorikin

You do when you let off the gas which is pointless in racing but nice for showing off downtown:loser:

autos are very good for dragging with. i went to the track a couple days ago and my times were EXTREMELY consistent. i will post my ever-so-slow timeslips soon...

i would have won a trophy if i didnt burnout in reverse and screw up my tranny during the final run :mad:

NA and Turbo is just preference of the driver. I mean, outside of the drag world...i like NA a LOT more. Much better throttle response (and yes, turbos are getting better at this, but still). N/A just feels better. But it is really hard to get them really powerful, but well, its all preference and what you want to do with it.

well to each his own. i just love the feeling of boost when it kicks in hard, and its a continueing build up off power.

fact of the matter is that NA has a wider usable powerband...BUT
with a turbo...your power band will have more...power
dollar for dollar
turbo is the way to go
granted it is expensive to go from NA to turbo...in the long run you will have more power than with the same dollar amount in an NA car...
then build that NA to the same power level as with the turbo...take that $$ and throw it in the turbo car and youll still have more power...the difference becomes exponential
turbo lag can be a pain in the ass and the car will be hard to drive. driving cars with large turbos is hard...thats why many of the 800-900 rwhp supra guys are stuck in the 11s and 12s
it takes a good driver to drive a turbo car...it takes a great driver to drive it well

Wanna feel that? Go drive a standard WRX. Not an STI.


Whats the difference between a 600whp Supra and a 900whp Supra? 11 second time slips :tongue:

There are some advantages and some disadvantages. The N/A has a faster reponse and the turbo for a little while you have a lag and you dont use up the horsepower as quick as the N/A. --Of subject-- One tokyo xtreme racer mr2 has 512 or something and nsx has 432. NSX IS WAY FASTER!!!

omg you base your knowledge on a video game?
this makes me sad

what makes someone "quick" is the horsepower:weight ratio
also...saying it again...the driver is the key
like i said earlier...anyone can drive a car but it takes a great driver to drive it well

oh and that supra joke is what do a 600, 700 and 800 hp supras have in COMMON...i think it makes more sense that way

Wow, so we argue about a really interesting subject by using video games. Tokyo extreme racer doesnt even have freakin licensed cars. How real is that?

the key to winning any race is to have good driving techneques!!!

or a very fast auto :tongue: those are hard to come by though...

i think im just gonna sell my car eventually and get a plain 240 with nothing done at all but a sr20 or ka-t swap. its way cheaper that way.... i think like 5000. or i can look around for a modded one for 7 or 8 g's.....

i cant wait until april.... :thefinger

Why not just do a damn swap. Youve got so much done, its a waste to throw it all away.

i want to run 12's... no way in hell i can do that with my car, and it being an auto. i'd have to start upgrading the engine... and its starting to have a lot of miles on it now. i think i should get rid of it ASAP

i think i can get 6500 around me... locally. 240s are rare cars around me, especially the one i have. i can get a modded one with sr20 swap and many extras including a body kit if i wanted one for around 8000... so for another 1500, basically the cost of just making my car a stick, i can have a whole other car with a lotta extras. im not sure yet, my car is being repaired tomorrow, and i wanna see how fast it is after that. if it is noticeable faster (low 15s) ill keep it and i might throw in a stick. if not i have to seriously think of selling it.

im not sure.... :mad: :mad: this is irritating. you really think i should keep this one? hmm maybe i should

somebody in here was talking about added weight a v8 adds to the front of the car..... some smart guy figured it out and with a Ford 302 with aluminum heads and all it was 40lbs more then the KA24.....40lbs can be taken down by removing battery to back, shit turbochargers arent pieces of tin foil shit either, those big ass t76 and t88 weigh about 80 lbs.... plus all the added piping, intercooler, BOV, wastegate, and extra lines just for the addition of a turbo.... it can take up some weight as well....

an extra 40 lbs is nothing, especially if you have some decent suspension mods.

Dude, keep the car. If you want a stick and more power, just swap an SR with a manual tranny. It'd be best to do it all at once. Youve already put so much into that car. Your car has decent suspension, and great looks, next step is a new engine. There is no need to start all over...waste of all the time you put into your current 240.

:iagree:

No, get a stick and KA-T. It will be a helluva lot easier to run 12s.

an old 302 z28 Chevy Small Block......

Edelbrock Torker Intake Manifold, Performer Carb, Cam and lifters, easy 300hp for a few hundred bucks....... easily in the 12's with traction.
About any v8 into a 240sx will get you in the 13's I would say, seems around 300hp is when people break into 12's and shit..... there are other cases though lol..... like Supras ha ha ha....

:tongue:

*edit*

I really like the idea of a 302 Chevy engine in a 240sx. Lets face it domestic engines aren't that bad, just a bit different.... its the cars that blow wind...... v8's into smaller nimble chassis has been a succesfull thing to do ever since they have been out. a S13 is a good platform for a v8, and many like the Z car v8 swaps as well. The 302 is an engine from Chevy that is just like a 350, or a 327, with different displacement, when you order parts all you need basically is small block chevy, tons of things interconnect. I don't really like 350's, 327's are a bit better. A 302 is a wicked v8 though. 4" bore..... 3" Stroke...... it was made for racing purposes in a homoglation type car(first z28's) the engine likes to rev and go high in the powerband...... I would love to see or make one myself, a 3-400hp 302 chevy into a 240sx...... I bet that thing could whip some major ass..

you can't fit v8's into a 240.... if you can please give me all specifics and i'd go and buy one this afternoon.

blue and corrupt.... do you know what you're talking about...... most of the money i put into my car went into performance. getting a whole new engine would change my whole car... and suspension upgrades i did are common on modded 240's. i can find a 12 sec 240sx with a body kit, paint job, decked out interior and suspension upgrades for around 8000. no way i can get into 12's with my n/a. i thought about water injection, i heard that rocks, but i prolly cant get more than 15-20hp from it.

I love all these Supra drivers, especially MK.III guys who think theyre the shit, because of these MK.IVs

Owning an Mk.IV is the only time you can say you have 600whp but you run 13s lol.

yay my car is running a lot better... i can finally take a 120 degree turn again going 35 without ramming into another car :biggrin:

it wasnt my tie rod end, my header was rubbing against my steering column... not good at all. i have a decent size spot in my header now.

at least it's fixed, and only costed $20 for the welding. if i had a freakin lift i would be able to do it myself.... i wonder how much one would be....

if ur talking hydraulic lift, my old boss got one used and installed for 4000 .. it was a nice lift, a little old, but in perfect working condition when oiled.


then he got an new one from snap-on it think, and it was like 6500 installed, and the snap on guys come and install it for u and everything


EDIT: also glad u got ur steering fixed.. now u can take it out for a boot and take some videos.

oh take pics of ur interior like where the center console runs between the seats.. and if u can, squeeze in the back an get me a pic of the two seats and the center console between the seats too...

i will have a mockup of a camera holster for u
:bigthumb:

awesome


actually 4 grand isn't that bad for a lift, i bet i can get one rigged up, if only i had enough space :frown:

here's a pic i took a while ago from between the two seats
