Hey all

I have a 34 sedan auto. I was going to swap it to a manual but I dont mind having an auto daily.

I am going to get a shift kit put in but i need to use the car still, so will be buying a spare gearbox to do it to in the mean time.

My question is, is there any other boxs that have at least 5 gears that will fit the neo 25det? That can take around 300kws? And can be used with the steering wheel controls?

Being a daily and cruise it on the highway just feels it needs an extra gear or two

I don't think so. Remember that the TCS is in the ECU, and they are only meant to talk to the gearbox type that they were intended for. I'd bet a few bucks that only the RE040300274624376478 or whatever it is that lived behind RB25DET Neos will do. Keep in mind that there was only a short window of time in Nissan land where they were doing slightly tricky boxes (with steering wheel shift, etc) on the RBs. Essentially just the 3-4 years of the R34. After that, it all went VQ.

something 5 plus speed tho I guess

Yuh....but how would you control it? As I said, the TCU is in the ECU. They talk to each other directly - it's not as if you can plug in another TCU. And the TCU you have is unlikley to want to talk to a different tranny.

You can get aftermarket ECU's that will take control of an auto gearbox.

You can seperate it out from the neo ECU (or run a haltech, other standalone manual-only ecu).

You can repurpose the steering wheel buttons to do other things (such as, shift up/down as an input on an aftermarket transmission ECU).


That said, don't.
NFi what will bolt to a RB that isn't a RB. People definitely can though (plenty of auto 2 and 3 speeds for drag on RB's) but lol I can imagine the pain of trying to get a ZF 6 speed working with a RB. It would be easier to just put a LS and it's auto or a Barra and it's auto in at the same time and massively more advisable than just doing the gearbox.

I said you can’t do it.... as in a sensible person shouldn’t do it. Strange word choice I know.


you can get stand alone 6l80e controllers if you are after 6 speed auto that’s quite strong and a massive head duck to get it working correctly. 
and probably won’t fit cos it’s massive. 
 

get a shift kit, report back

      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.

      Boost cut after swap(RB25DET NEO) R34

      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)?
