mine doesnt have the red and green pipes and it works... just gotta **** with the auto tps

damn, i must of really struck it lucky when i got mine (for free also) i knew **** all about XF tb mod before hand. My dad just had a ZK fairlane he was getting rid of, and i heard about the XF tb mod before so i thought i would see what size the fairlane one was, and it was same as the XF and looks pretty much the same as the xf one. Also scored a 25 spline LSD center out of that car Anyhow, those little red and green pipes ain't gonna affect your performance. its only for pollution **** haha Some original photos have not been recovered yet.

Off topic But Wow! That is a damn nice engine bay dude! By the way, your power steering needs to be topped up :P LOL

i still ddont get what you need to do with the wires in an auto can somee on that has done it please explain it clearly ? thanks

I belive it would be easiest to modify the VL auto TPS onto the XF TB Some original photos have not been recovered yet.

ok, so i've got my xf throttle body. the wrecker assured me it was a series 2. (trustworthy as they are) however, i don't have the big black TPS. I have a little grey one with a black ring around the butterfly shaft. can i use this or will i have to change it to a big black TPS or should I throw it in the bin and get another one?

about the TPS... would i be better off buying an XF TPS or a VL TPS to put on my xf t/b? i think i've got the variable resistor type and need the on/off switch type, but just need to know which one will be easier to fit and which will work better out of VL and XF TPS..

Probably be best to make the VL one fit if you don't have the on/off XF tps one. How that is done, i don't know. Maybe a few other people that have used the VL tps can share?

pics would be great too if anyone has them?

ill grab somep ics for ya!

does anyone have or know anyone with a spare VL TPS lying around? the wreckers wanted $44 and holden wanted $123... screw that.

dont be a little girl and get the one from the wreckers ! OR Put up a Wanted thread in teh for sale sections?

i've already done that and have found one for less than half what the wreckers wanted. why am i a little girl for wanting to save money? i don't know about you, but i don't like being shafted for a part of questionable quality. each to their own i suppose..

I did the same modification to my old ET turbo once upon a time.. I fitted a VL TB to it, which is about the same difference as putting an XF TB on a VL... It did make slightly more power, approx 2kw atw on the dyno. But the extra power insn't the reason for doing this modification. It mainly affects throttle sensitivity. If you've ever driven a powerful newer EFI car, and then got back into your VL, you'll notice that the other car got moving and had more power with less throttle than your VL.. So in doing this modification, it basically makes your VL feel like a more powerful car to drive on a day to day basis.

one more question... what tb screws did you use? the VL ones are too long and they have a washer on them that fouls on the XF tb.

just to let you know mate that pipe with the red ring has a hole on the inside of the TB which isnt far off from the green one.

i finialy fitted my XF tb on weekend but when i have AAC valve wire disconnected it idles sweet around 900RPM, but when i connect the AAC valve wire it idles at nething from 1200-2000RPM. so ive dis connected AAC for now til i get it sussed. ive turned idle adjuster in plenum fully in n it stil didnt do nethnig so i screwed it out agian, you guys got ne ideas to why its doing this high idle. Thanks, DAMO!!!

Have you tried adjusting the screw on the computer back to nothing and then adjusting the idle at the plenum, should work a treat. Mike

try your plenum screw and your tb screw and adjust them.. i have ha the exact sameproblem and still do.. went out and bought another tb for $45 and it hasnt got ****t bushes in it and itretracts properly.. mate in your caseim thining you might have the same issue i have... over tiem its gone from idling at 1500rpm to 900 after time.. maybe a bur which the butterfly was catching possibly? should see how it all goes once i put ths other one back on..

Cheers guy's i'll give it a try & keep ya posted on what happens. damo
