Fitting RB25 Spec1 Throttle Position Semsor

Recommended Posts

Firstly it is very important you get the correct TPS as far as I am aware spec 2 ones won’t work. 


3 simple steps 

1  Grind back the pin on wich the tps mounts until the new tps sits flush with the mounting surface

2  Tap the two already existing holes (circled in red) 

3  Enlargen the mounting holes on the tps

This tps has two plugs one you will not use.

the one marked with the tick is the tps


the other is used by the skyline ecu due to them using auto gearboxes (this may be incorrect but it is my understanding)
