And after ringing about a million wreckers in brissy for a Q45 throttle body and having no luck i thought i would see what other people have bolted on their greddy style plenums, was thinking of getting the adaptor kit but would pref to put a larger T/B on

I think the old XF throttle bodies were also being readily used not so long ago.

[m0rt]

is there any modifying needed to the TPS for an XF T/B??

Or you could fork out for something like a Hypertune throttle body and get it adapted on.

have you tried getting in contact with these guys?

This is covered in the PFC FAQ in my signature

have a read of it- tells you what TPS to use when using the XF throttle body

Hey thanks for the help guys,

dunno if i wanna spend that much on a T/B, but if i got no choice then oh well

i sent a pm to Kudos just waiting to hear back

and need to find a wrecker in Brissy that actualy has an XF T/B b4 i can try this option, just one question with that, it says to use an RB30 TPS, i saw one yesterday at a wreckers and it had what looked like the grey plug which is on mine, but there was a black plug on there also, does anyone know what thats for? Does it have to be hooked up??

The second plug is usually for the auto.

How much power are you targetting? I haven't found the standard throttle body to be a restriction at 320 rwkw.

WA_r32 is selling Q45's for $220 each (he has 2)

jump onto the WA for sale section

My engine in it's previous car was making ~365rwkw through the standard throttle body.

Benefits of a bigger throttle body?

Would it be less restriction? thus allowing you to make the same power with less boost?

I'm finding it really hard to justify a new throttle body...

[bazr33]

im pretty sure i have the xf throttle body with rb30 tps at home if you were interested?

pm me if you are.

I have a xf throttle body on my car with a rb30 tps and using the r31 accelerator cable.

[m0rt]

Cheers Sydneykid, i'm looking at high 200's but if it gets 300rwkw then even better

Does a stock tps fit these?

[600hp]

The Hypertune unit bolts straight up and uses the stock Rb25 tps.

It has the same flange and the Q45 but had a larger 85mm id.

When fitted to an aftermarket plenum Autosalon made an extra 15kw at the wheels. Power went from 200rwkw to 215 with no loss down low.Same boost

At 315 rwkw I measured the boost before and after the standard throttle body and there was zero difference. So the standard throttle body wasn't a restriction at that power level. There are better, more effective, ways to spend your money for that power target.

at what point would you think of changing the throttle body Gary?

im going for around 360rwkws on a 30/25 with 3540r

I don't know what the limit is, all I know is it's OK at 320 rwkw. The best way to find out is to measure it, that's what I did after a lot of people said 265 rwkw was the limit of the standard throttle body. My best suggestion is to get your 360 rwkw and then measure the boost before and after the throttle body, it's pretty simple. Only takes a couple of minutes to check, then you will know for sure.

It sure does

I don't have any high res pictures on this PC but here is a picture of our unit fitted to an R33 making a tad over 300rwkw's.
