Throttle Body Choice

[teazn_r33]

looking at a throttle body a need a big on to fit a greddy plenum

which one should i use and how much should i spend

if anyone has on please tell me wat and how much

[fraz gts4]

I used an 80mm throttle off a q45 v8, it bolted on and was half the price of a shiny billet one

hypertune ftw!!!!!

[teazn_r33]

i cant seem to find a q45

[SilverECR33]

got any info on these Hyper tune ones? sizes available, prices etc. and what they are like.

Do not use the q45 90mm throttle body. It's not made for supercharged applications and the seals around the throttly axle will leak boost pressure. I've bought 3 tb's and tried before I gave up. They all leak after 0.6bars og pressure

That seems strange, as even the genuine greddy manifolds are drilled to suit them, there are 80, 90 and 100 mm anodised throttle bodies on ebay for under $300 new

My local rod shop supplied me with a machined billet number that sure looks the goods. A tad over 300 dollars from memory. and its 80 mil. It doesnt bolt directly to the greddy plenum but it wont be difficult to make it fit.

I looked for ages for a q45 and gave up trying to find one. When you do they sell for around the 250 dollar mark anyway so I figure for the bit extra its worth it to have the new one.

Just get a tb adaptor and use the stock tb

[teazn_r33]

i think that the standard trottle body will be a restriction to make the 350rwkw in my rb so im just doin everything slowly and getting everything over a period of time all those billet ones on ebay are in chine and i can get better quality from here and its aussie made "support aussies as much as possiable" lol

pretty funny while driving a jap car haha

they are very informative and know what Q45 throttle body is,

I should have bought mine from him but went to somewhere else, not a good experience.

I managed to get a Q45 MAF and Throttle body for my RB25/greddy manifold,

Anyone know how much of a challange it is to set up a PFC for the Q's maf and TPS sensitivity?

[sicrb25]

MAF you just need to set VH41 from the settings menu.

[ULOOOK]

Q45 are the go, they pop up on ebay from time to time.

I have a $500 billet throttle body and its nothing but problems.

[ISL33P]

80mm $470 or $570 100mm

with tps and tps plug which can be wired into rb harness

come complete with weld on adaptor

[Rezlo]

Why you guys paying so much?

Ive braught in 4 or 5 sets from the US to South Africa, i pay on average $150US for MAF and TB and about $30-50 for express air mail.

I agree that does seem strange, ive used one on my car for over a year (490hp @ 1.2bar) with no issues or leak what so ever.

hypertune ftw!!!!!

I just had a bad experience with a HYPERTUNE plenum for a EVO (real animal with well over 300awkw), awesome plenum but overpriced and required ALOT of work to fit.... and the HYPERTUNE throttle bodys are flat out junk.
