I'm going to hold onto it for a week or so until I confirm things.

I don't want to mislead anyone with incorrect information

[ed]

Can somebody either confirm or deny this?

<{POST_SNAPBACK}>

Yes 34 GTT's are bigger than the 33's.

Ask abobob about it, he knows

The R34 housing is noticably bigger than the R33 one. I've had them side by side and photographed them for the forum but the pics have been lost in the migration.

That's why when you lot all started crapping on () about VG30 turbos I pointed out that the R34 turbo also has a bigger exhaust housing which is why I got 228rwkw from an AUTO at 12.5 psi.

[Bass Junky]

Very keen on getting the pics

[Abo Bob]

How do you know? And have you replaced it?

<{POST_SNAPBACK}>

I am pretty sure because it has happened to other people before with R34's and I took notice. Then I spent an entire drag day deducing the problem. It was fine for one run but then do a second without 20-30 minute cooldown and the power loss was dramatic.

I have replaced it but not really tested because it doesn't really happen on the street. Only on the strip and down the straight on the track.

i managed to locate a vg30 single turbo and it is now down at gcg along with an r33 turbo getting the hybrid hiflow done. im interested to see what sort of power i can expect from it, im aiming for 250kw so will update when time comes.

[sweetr33]

oh and by the way if anyone wants a vg30 single turbo the fella i bought it off has another one co-incidently and is on the gold coast so pm me for his contact number

[sweetr33]

got the turbo back now and it looks good,its amazing the difference in exhaust wheel size in the standard turbo to the hiflowed one.Much larger im eager to see how it drives and boosts so in afew weeks when i get my car running will let u all know

Pics... Some nice macro ones of the comp wheel.

I'm keen to see the results.

[sweetr33]

well i finally got the car going with this turbo setup although i have rebuilt the engine, got cams now etc so not just the turbo upgrade which makes it hard to note the difference in turbo response etc plus im still running the stock cooler and ecu at this stage as funds are not in my favour. Turbo duz feel nice although im only running stock boost and the car is definately faster that before with the stock turbo and running 13psi. just gotta eliminate stock cooler, ecu, dump pipe and injectors and i will be able to put a power figure down

I just made 250 rwkw with my GCG R34 GTT turbo.

can anyone 100% confirm the r34 housing is the same as the vg30 ? ive been told its bigger than the 33 but not as big as the vg30

[Bass Junky]

it is IDENTICAL in every way shape and form.

I've had them both on my desk and measured every part of them and they are the same.

Don't go telling everyone and all the wreckers, or the prices will go through the roof again.

[32vspecII]

awesome!

this makes a hi-flow vs gt-rs decision even harder

[sweetr33]

i'd do the highflow but each to there own

Are you hi-flowing your stock turbos with a VG-30 BB or a Garrett hi-flow.

I have these mods in my car now and which of these other mods do you think I should get or add first.

What I have now.

1: POD

2: TM duel boost control

3: Split Dump Pipe

4: Exhaust from Turbo 3" tip

5: A cheap FMIC

6 Apexi PFC W/HC

What do I need in addition first

1: Walbro fuel pump

2: Fuel reg

3: Z32 AFM

4: Injectors....which are the very best for a 1996 GTS-T SII?

5: cam and which kind and the benifit of them, exhaust and adjectable...why them and which brand is best?

I understand a lot of these questions may have been answered before but I have just arrived in Australia, so all your help is so much appreciated.

1: Walbro fuel pump I don't trust them. There are other options.

2: Fuel reg No.

3: Z32 AFM Yes.

4: Injectors....which are the very best for a 1996 GTS-T SII? Some Nismo 550cc ones will do.

5: cam and which kind and the benifit of them, exhaust and adjectable...why them and which brand is best? Adjectable? I recommend a pair of Tomei type b Poncams.
