Xf Throttle Body

[adam87]

hi

i have done searches regarding this but can not get a definitive answer.

i have an rb25 with a forward facing plenum which was designed to be used with a xf throttle body.

i know they open up differently to rb25 ones.

so i need to know which TPS i need to use. i have heard that you can use an rb30 one and modify it or an sr20 but cant find any concrete info on which is easiest.

if the sr20 one fits without modification id prefer to go that way but if not and i need to go for the rb30 one well ill deal with that as it comes. if you need to use the rb30 one is there a wiring diagram that shows exactly what needs to be changed? and are the rb30 n/a and turbo ones the same?

thanks

im using one on my RB20 but im using the stock RB20 TPS. it just has a little bracket made up so it bolts on as normal.

Ford Falcon XF Throttle body with the PowerFC

Some owners upgrade the standard Skyline GTST single throttle body to a larger unit. A common donor for this part is the Ford Falcon XF Throttle body. The problem with this swap is the throttle body opens backwards on the XF unit so the TPS signal wont match. You need to use the Nissan RB30 TPS sensor which is the same as the standard skyline one and works with the XF unit.

so use a standard unmodified rb30 tps and it will plug straight in and work perfectly fine i take it then?

I no its an old post, but isnt the rb25det throttle body the same size as a xf? 68mm?

WHY RB30 TPS ??!? Why cant the standard XF TPS that came with the XF throttlebody be used ???

FORD XF TPS PINOUT :

GREEN - SIGNAL

ORANGE - 5V

BLACK - EARTH

They both operate at 5 volts so why cant the ford unit be wired into the standard RB25DET harness ?

I know the series 1 and series 2 RB25DET TPS are different as the series 1 has one plug and the series 2 has two plugs -
