in the process of puttin on my Greddy intake plenum and everythings goin great till i come to the Q45 throttle body. I thought the rb25det TPS sensor bolted right up to it. But i got a Series 2 motor and the TPS is completely diff and will not bolt up. Anyone know what TPS sensor i could use?

heres some pics

s1 TPS bolts right up, I think your harness is different though... gonna have to re wire either way.

Search my man, this has been covered in here already, actually if you scroll down in the RB section you should find the answer, I know it was answered not even a week ago

Haha, well I was going through the RB section and saw the thread for you! Just three threads down from yours and 2 other people asking the same question as you! Everyone must be getting ready to start up their RBs or something! haha

Does anybody even sell replacment RB25 S2 TPS sensors? I'm getting ready to install Haltech E6K and going to replace mine cuz it sometimes acts up and goes out of the spec range at full throttle. I'm still using stock throttle body and manifold. What would be a good replacment?
