Seeing if anyone knew if the R34 Neo 5spd manual transmission will work on the R33 RB25DET?....I have an S13 right now with an RB25 in there and had the stock R33 5spd, but it gave out and cant find that many R33 transmissions around. Found this R34 Neo transmission that I can pickup, but wanted to make sure that the bell housing would bolt up to the back of the block without a problem and also check to see if it is the same general overall size so that I wouldnt have any troubles with the tranny tunnel or driveshaft that I had made for the R33 setup.

Thanks

yes it will.

youl need the shifter and a pull clutch/flywheel asembly.

either.

r33gtr or r34gtt. 250mm clutch :)

i had one in my dr30. nice box with good ratios and very smoth operation.:wub:

I am about to fit an R34 box into my 33GTSt. (Auto to manual conversion)

as T04GTR said, all you need is the gear lever and pull type clutch.

everything else bolts straight up.

Why do you want to put a r34 box in it?

Works out cheaper to put the 33 box in doesn't it? And push type clutches are cheaper....

I just got my car back from a manual conversion So just curious

P.S help me out here: http://www.skylinesaustralia.com/forums/in...howtopic=154422

I got an R34 box as it was all I could find at the time.

Push type is cheaper.

For your conversion you need the wiring harness from the gearbox up to the fuse/relay box on the drivers side inner guard for the reverse lights to operate.

For the speedo to work you need the manual speedo gear drive in the box and a manual speedo head or it may be easier to buy a complete cluster second hand.

Dont ask me why Nissan have a manual and auto speedo head, but they do.

Hope that helps.

Buy the R34 box and swap the front housings over, i just finished doing this 26 conversion with R34 box in S13 ( www.uras.com.au/democar.htm ), i hate pull clutches so used a R32 GTR housing but R33 GTst works exactly the same.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
