RB SWAP FAQ FROM UNSTABLE. GOT AN RB QUESTION? LOOK HERE FIRST!

interesting

i am planning on swapping a rb20det into my 91 nissan 240sx se coupe. i was curious if there will be a large difference in my weight ratio running a rb20det rather than sr or ka? also, i was wondering if any other sites are out there selling rb20's i want to get bunch of price quotes before i actually purchase the front clip.

Im new to the forum and I was wondering if anyone knew where i might be able to buy an engine preferrably an RB25DE (non-turbo)? Even if its just to buy the engine then have it installed by me or a local shop. I cant believe the amount of stupid questions. But any help would be appreciated.

I am not sure if they still have it though. Try calling them.

Hi, anyone I got a 91 Nissan 240sx
My speedometer is not responding at times, the needle marks at higher speeds.
Does anyone know were I can locate the vehicle speed sensor, and how do I check it?

Do I need to change the cluster?

thanx for the help :sunglasse :smile:
Hey i was just wondering if i could swap RB26DETT in ma 1996 240SX, and what kinda mods would i have to go through and is it worth it?

Ive planned a lot of upgrades for my KA24E engine but im having a tough time finding a after market throttle body.Looking for something in the 550cc area. Can anyone help?

I'm a little confused on the RB25det mounting into the S13. I want the engine to sit properly in the engine bay, as in not sit 1" high and1" forward. I am currently planning on buying a front clip and the motor mounts from mckinney motorsports. Will I be using the R32-33 crossmember or is a custom crossmember going to be supplied with the mounting kit, or anybody's mounting kit.

I'm asking because if the crossmember is replaced by the kit then I have an option not to buy the front clip and instead purchase an engine swap kit.

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

thanx for the help :sunglasse :smile:
I have a stock rb26dett in my 1991 type m with a front mount I do agree that spark plugs are a pain but doesnt take me 2 hours.

I thought it was the RB25 that was a pain to get to the plugs because of that weirdo intake manifold that goes over the valve cover.

Logik your ummm whats called "Correct"..The RB25DET is where Nissan went "wait a minute... are you saying the Intake gets hot from sitting right above the Head? no way? Customers complaining about changing spark plugs? Ok ok...for you the public having troubles with the Spark plugs well throw in a bigger Straight 6 and another Turbo and make it AWD. will that be ok?"

Is the RB26 alo hard to get to the plugs? Cause it doesn't have a cross mount manifold.

I can asure you all that an easy Skyline swap into any S13/14/15 is to bolt the Skyline cross member up in place of the SR / CA cross member and use the Skyline engine mounts. The S15 6 speed manual is a good box for less the 400rwhp otherwise use a R33 5 speed manual or Trust 6 speed dog engagement box(read: EXPENSIVE)
.
Being in Australia, I have an S14 Silvia with an R34 RB26DETT N1 motor, Twin HKS GT2530 turbo's, Hollinger 6 speed sequential(Read: MEGABUCKS but is indestructible), 4.11:1 Ratio Tomei 1.5 LSD as a dedicated hill climb, drift and race car... It was a surprisingly easy install and honestly with a basic mechanical knowledge can be done in a few weeks... Did I mention I have a reliable 500rwhp??

Hello... I just got my 89 240 sx se, as a kid i have no money but i have a little from working hard. Im new to nissan, i had a rx-7 that i just recently sold. If someone could tell me the best possible motors for the 240 i would be very greatful. Ive done some research and ive found the SR20det and the RB26DETT i belive is a skyline motor. Can someone please tell me what my other options are and cost efficently. Thanks

whats the labor cost for swapping a rb26 into a 98 240sx ive heard a lot of shit anywhere frome 2k to 8k and tat range doesnt help much, im wondering because i might go with the ka turbo kit now to lay down an easy 300 to the rear wheels to be cheap instead of going witht the SR if the RB swap is cheap enuf.

Does anybody kno were i can get some Gram Lights 57pros 18x9 in the front and 18x10 in the rear with a 32 offset and 5x114 bolt pattern for cheap. Also looking for a Rotora Big Brake Kit for under 1800 and some Tanabe sustec type s coil overs for under a grand if anybody can help that wold be great cuz i never find anything searching the net.

You will not find any of that shit for cheap unless you buy them used from Japan (as in physically going to Japan).

The only logical reason I can see behind doing a RB26 swap is if you are going for a record for the most RWHP in a 240. And if you ever saw any high HP 240s, you'll know that anywhere above 300whp is plenty to keep up with most high end european and american sports cars. Anything past that is insane. Just watch the ultimate ka turbo video. Search for it. Tat posted it up a while ago.

I have also been wanting to swap an rb25 r33 motor in a 240sx. will i need any extra parts? i have found a company that will sell the motor and tranny for 2500 and the 240sx for 2400 is this a good deal?

New To This, So Forgive Me, I Am Looking At The Rb 26 Dett, I Am Trying To Find A 97-98 Bodystyle 240 Is The Rb 26 Dett More Desirable, AND TUNEABLE?... The Awd Conversion, Is It Worth It? Mine Will Be A Daily Driver, But I Like To Blast The Lights, And Curves.....

blast the lights AND curves. hmmm id stick with the ka24de and turbo it, thats alot of added weight up front if you swap an rb

If you want more than 500-600whp on the street, then you should look into a RB25 or RB26. Mate the RB26 with a RB25 tranny for RWD. I hope all you new guys didn't forget that there is a FAQ at the beginning of this thread.:rolleyes:

i have been through the faq's and couldnt find anything addressing the issue, i take it the rb25's tranney is stronger then? what would you recomend i do to get this kind of power? (as far as addressing the motor as an entire system where one change affects another part) i am totaly new to this, right now i have a 69 corvette stingray, and the asian cars are so different.

Learn A LOT before you venture into the 600whp FI world. (If you don't know what FI means then you don't know enough.) The reason to use the RB25 tranny is because the RB26 tranny is AWD, the RB25 tranny is RWD, DON'T EVEN THINK OF CONVERTING THE CAR TO AWD.

trying to learn as much about it, before i do it, as i can hence the questions, i have been all over google, (it is what brought me here) and looked, and read as much as i can find, any good info sites you would recomend? and you didnt address the "car as a system" question i had... any advice, pointers or anything else you can offer is greatly appreciated. for this project, i am going to have between a $16,000 and $18,000 budget. i have found a local shop (reputable & reccomended) that can do the swap, but i want to know what to look for, ask for etc. my goal would be to wind up with 400-500 rwhp.

500whp is easy with an RB26, just bolt on some bigger turbos, upgrade the fuel system to be safe and it'll get you there.

cool, you dont know of anyone who makes a wide body kit for the car do you?

i like the idea of the twin turbo, can the rb25 be turned into a tt? what kind of steps should i do to do such a thing? the mechanic i am talking to is pushing me to the rb25 too, says with the 26tt, that one of the turbos is pressed against the firewall. rattles, and threatens fire on the otherside of said firewall. and that there is a lot of cutting required.

TT is no better than single turbo. Single turbo is much more simple and leaves you much more underhood room. Less heat as well.

This car is no different than any other car. To make more power, you must put more air through the engine with enough fuel and you must ignite the AF mix at the correct time.

I hope you realize that 500whp in a 240 is useless on the street.

dosent the tt setup stop the idea of 'turbo lag' by having one turbo spooled faster and therefore outputting more power sooner and then when that one is wound out, the second kick in?

& yeah, i know 500 whp is useless on the street (do you think a viper owner thinks that too? (i used to have a 96 z28 six speed and came across a viper (or rather the viper came across me) that just totally walked away from me like i was standing still) ... but it sure does make fun for shits n giggles.

You're thinking of sequential turbos. Preference really. But go to phatka-t.com and watch a couple of thier vids. Mainly the 500whp on the street and tell me they have lag.

A viper is much heavier than a 240 so wheelspin is not so much an issue.

those vid's are insane! i like..... any other sites anyone could recommend for research purposes?????

I believe all of them have video sections. I usually go to ka-t.org, nicoclub.com, and phatka-t.com. All really cool guys. This one is the best though:

I've been reading this complete guide (it's great!)

but i still have a question rewgarding the RB25 swap.

here in europe, the 240sx's are standard equiped with a SR20DET engine.
is it worth swapping it to a RB25, or should i put all my money in the tuning of the SR20DET?

Tune the SR and stop posting questions in the Stickies.

i have a rb26dett on my 1990 240sx. im getting backpressure on my turbos as soon as the blowoff valve close. i can feel and hear air coming out of the filters. somebody have an idea may i need to install another blow off valve?

Sounds like the spring is to stiff.

Common occurance on tuned RB26DETT's, HKS even make an air flow meter idle computer(exact name unsure) to compensate for this air reversion.
BOV spring pressure helps but it is a pain when your Air Flow Meters get so much air rushing past them your engine stalls :(

For those of you that are interested in swapping out for a rb26dett motor i would like to maake a suggestion. First off i would suggest that you go with a Rb25det first and foremost because of the way the engine would have to be installed to fit both turbos is way to pricey! secondly for about what it would take to install a 26 you could pull out almost twice the power out of the 25 and have it much more reliable. installing a rb 26dett correctly you are looking in the ball park of about ten grand doing it yourself as aposed to the 6 grand for a 25 if you were to do it yourself! In the end that is m opinion and just a suggestion. the typical reason someone would install a rb 26 motor is just to say hey i jst spent a ungodly amount and got a stock twin turbo skyline motor. But to each his own.

True True, all True.

But I wouldn't take back my rough idling, badly tuned, rb26 swap even though I spent over 8K on the swap. The look on people's faces when they see that motor is priceless.

In the end though, my car would be twice as fast as it stands now if I went with the RB25 route. But I'm hoping that the potential for HP down the line will outweigh the cheaper initial cost of the RB25. They are similar motors, but still, so very very different.

ok this is a lil old post but hopefully ill get a response... im planing on makin the RB26 swap... if i got the engine... got the car... yada yada... tranny... how much would it cost to JUST get it put in so it fits

Around $10k probably. It's worth it though because the RB is the shit!

haha your dumb. if i had all the parts + the car...the RB goes in for exactly $0.

i knew you were a homosexual when it comes to working on cars.

having a shop build a car for you = you may as well say its the shops car, not yours.

and whoever tries to say any thing about that, look back into my first posts of my red 240 and then shut the fuck up about it. i do all the work myself.

i do all the work myself.

no wonder it's so slow. you need more e-rams.

slow? yeah umm its not done yet. you obviously decided to make a crack on what i said without even listening to simple instructions.

... look back into my first posts of my red 240...

im not even upset because of how much of a dumbass it made you look like.

JDMsux... you claim you have a 240 with an sr20 and you showed us pics and yada yada.... then your saying the s15 blacktop is the best motor and tranny blah blah.... then you say the RBs rule and more blah blah.... it all just adds up to me asking a question.... why is your username JDMsux? you do realize JDM = Japanese Domestic Market dont you? and that SRs and RBs are JDM motors? :screwy:

and before you go saying shit to slideways... what do you have to show? yea yea you showed us that 240 in another thread, but you never provided us with proof it was yours. so until i see that, i dont believe it. not to mention id say slideways has a pretty nice setup going on. so the cars not done yet... BIG DEAL! how many people do you hear actually say their car is "finished"? sure people have goals, but even after these goals are reached, it is still an on-going project. JDMsux, grow up.

My username is JDMsux because I couldn't fit "This whole JDM fad sucks and everyone that is on it is a tool" as a username.

Sorry I don't feel the need to prove that I own my car to a bunch of kids on an internet forum. If anyone has a legitimate problem I'll help them, but until then I'm just going to keep being a dick to the 900 people that ask what engine to put in their car.

maybe he used JDMsux as his name because he already used SR20DETpower...

well that answered my question about the username... but come on... lining up e-rams and all this other ridiculous shit you wrote... you know thats not helping people.. instead of posting meaningless threads.. why dont you just not answer? just my :2cents: ..

because hes one of those people who have no purpose in life except to e-thug. i was hoping that a mod would have seen by now that he brings absolutely NO benefit to these forums and just ban him, but w/e. all we can do is warn people not to listen to his retarted advice, just in case some newbie here thinks hes serious and blows up his car.
