im using an xf throttle body on a subzero plenum in a rb25/30.

PROBLEM:i need to wire up the tps and am having some trouble

i have been doin some research on how this will work but can some please make this crystal for me.

these are the questions i need answered

1- is the rb30 tps the easiest way to make the xf tb work with rb25?? if not what is??

2- does the slot in the rb30 tps fit straight into xf tb??? because the rb25 tps definately will not.

3- does the rb30 tps have the exact same plug as the corresponding end of the rb25 series 2 harness?? ie will the rb30 tps clip straight into the rb25 harness???

if this can be clarified that would be very appreciated

my questions werent really answered

im using xf tb coz im using a subzero plenum which is set up for that tb. and all my pipe works already done in 3" and its all perfect, i cant go back from here only forward..

so do you guys have answers or only criticism?

i have searched far and wide and have a rough idea but dont have definate answers for my questions.

Look on calaisturbo.com theres a massive thread on the XF TB installation and problems, like 30 pages massive, thats the best advice I can give you. They are mainly using rb30s but should be able to help you out.

i only asked as a 10 times better solution is a Infinity throttle body, as the tps is a wire in affair and has niceties such as temperature controlled throttle plate (cold start extra opening etc) etc and they are cheap too.

    • It's funny, as Ive seen plenty of people use them in cheap builds on YT. And they actually go okay, even though a lot of other maxspeedingrods stuff is terrible. Those turbos seem reliable enough, the only part being, a good quality turbo that is "identical" to it, will out perform it day in and day out. In both a lower boost threshold, and the ability to flow more air at the same boost pressure. As a cheap cheap replacement, not a terrible choice. For cheap and shouldn't blow in a day, not terrible (like other eBay/Temu turbos) for low cost and still decent performance, that's where the question comes in to play from the results I've seen. I'd actually find it hilarious to buy one, and strap it to a paddock basher or some other cheap as POS originally NA car, and send it to the moon!
    • The maxpeedingrods turbo is cheap and bolts on to stock parts. I think you just need a bigger silicone coupler for the intake. Its a cheap china turbo, but it's been running on mine for almost 3 years at 16-19 psi.
    • What do they look like right after you've tried to start it with everything connected? Also post photos of what they actually look like.
    • Also wanted to say, my new spark plugs are blackened looks like it's very rich. I have splitfire coilpacks but stock coilpack loom and ignitor. I tried directly grounding the ignitor ground to body as well.
