R32 / RB25 S2 Swap TPS Question

[lowexr]

Hey I'm doing RB25 S2 swap in my R32

I'm keeping the R32 wiring harness and the TPS/throttle valve swith connectors are differents on the s2 engine.

Can anybody give me wiring colors or TPS and throttle valve pinout??

hey i was just wondering if you ever figured this out? im in the middle of a 25 swap in my r32, also using the rb20det harness and just kinda dont have the bottom plug hooked up to anything

rb25 TPS switch is completely different that rb20 one.
which ECU are you using?

use an rb20 TPS on the rb25 motor with rb20 ecu

with rb25 ecu you might have to make rb25 tps work

[Skym]

The Series 2 RB25DET TPS as shown above is voltage activated for idle, WOT contact's (preset the voltage on ECU).

RB20DET TPS has pins for idle, WOT contact's.

RB20DET ECU needs Nistune to run that Series 2 TPS, which has software adjusted to suit (voltage activated idle contact, etc).

im using an rb25 series 2 ecu

[nick-nismo]

well since thoes ecu's cant be chipped your either going to have to wire in the rb25 tps
or fit an ecu that can be nistuned, rb20 or z32, and use the 20 tps but tune to suit
