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.

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.

    • Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that 
    • Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

    • What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
    • While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
