hi there, i am in the process of installing a rb25det in my nissan cefiro, my car is auto and unfortunately the engine i got is manual,,, apparently the loom is different with respect to the t.p.s,, can anyone tell me if there is a way to physically wire in that portion of the t.p.s into the loom? or maybe if there is a part of the loom that just have to plug into the manual engine's loom?

i know from the R31 the TPS has something like five connections

switch for idle/full throttle (auto/manual)

variable resistor from idle to full (auto only)

even though I had a manual loom, the wires were there for an auto TPS

the three TPS wires for auto in the wiring loom goes via the ECU to the transmission to the auto trans computer. ie the ECU itself doesn't even use the TPS auto variable resistor

if it is anything similar to the R33 you might notice the same thing. i know that ECUs are auto/manual but this is mainly mapping changes for load and injection cut off

visit www.gweeds.net as this guy transplanted an RB25 into a VL turbo and rewired the entire loom! hes got wiring diagrams on the site also but i couldn't get it working last time i visited

i would split the cefiro loom where these wires go to the A/T and put these into the RB25 loom

good luck!

      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)?
