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 (:P) 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.

How do you know? And have you replaced it?

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.

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

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

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.

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.

    • How's everyone going? Just a shout-out introducing myself. I'm James, I live on the north side of Brisbane. I bought an R33 that had been left to rot in someone's front yard for 14 years. Apparently, it has immobiliser/fuel issues. Long story short, it's suffering from a seized engine, plus whatever else turns up once it runs. The car is pretty good considering it sat for so long. It pretty much died after being imported. It has a bunch of Jap parts and a full Top Secret body kit. It's painted Fiat Turchese Festival, or aqua blue if you're not French. Another project to throw money at!
    • So the clockspring is responsible for the indicators cancelling on their own? I thought that was the function of that white thing in the center (any idea what it's called?)
    • Can you log IAT? Whilst WTA coolers have their place, doing any sort of sustained run is not one of them There are fixes that slow down the heat soak, like ice boxes, which don't last that long, and interchillers, which are fairly expensive, up grades to the WTA cooling radiator, which may require a bigger pump, and upgrades to the reservoir size,  and upgrades to the cooling fans, but, it all still heat soaks, and takes ages to come down in hot weather  For a turbo, that isn't locked into WTA like my PD blower is, can you not possibly swap to a nice air to air intercooler????, it would be better for sustained runs then, and have alot less things that could go wrong in my opinion 
    • So, the other thing I've sorted is a baseline dyno run up at Unigroup's new location. The auto trans was a little unco-operative by both shifting down when the throttle was floored on the dyno (so Mark had to ramp it up more slowly than in a manual) and also by shifting up at 6,000 even in sports mode instead of the indicated redline of 7,000 Still, on a hot day it made 240rwkw at 16psi which seems about right for 300kw (400hp) through an auto at the wheels.  The shape of the curve is not quite right because it was not full throttle to about 4,500 to stop it kicking down, but until I can get a tune on the auto trans control this was the best we could do.....full boost will be well below 5,000 once that is sorted, I'll get some data logs when I can to confirm For comparison, the R32 made 255 at 12psi (at 4,500) on the same dyno with tune, n1 turbos, cam gears, big exhaust but otherwise all standard so the v37 is likely a little better out of the box. One thing that is very clear is that the standard water to air intercoolers are not up to sustained use at full throttle in warm ambient temps. After about 5 runs (so only a few minutes full throttle), it was pulling boost and timing and dropping 10-15% power. Unfortunately I didn't get that printout and the Unigroup guys are away at the moment, will try and get hold of it on their return. So, looks like a healthy engine to start modifying and the only real area of concern is the w2a heat exchangers which the aftermarket has plenty of solutions for    
    • I maintain it actually looked really nice in person. So much so that I thought "No, this is illegal" but there it was, clear as day. I think we can easily call the wing and wheels/height to be transformative. Not saying it's better than the GR Whatever, or the 86, or the WRX STI or anything of that sort (the internet says it all bolts up so you can buy best of all worlds?) but it's still at least a thing and not nearly AS bad as people say.
