Who did you get to do the work???

Depends on where you are, local/interstate workshop?

How much did it cost?

Largely depends on *see above response*, and also how much work you are doing.

What sort of gains did you make?

As mentioned, depends on how 'tuff' you want the original one to be rebuilt to.

I've got my standard r33 turbo highflowed - did it a couple of months ago. I got it done with a lot of other work so i'm not sure how much it came to. Precision did mine (through Envy Imports located on the Northern Beaches).

My car hits fuel/boost cut if I increase the boost a little bit past stock, so I bought myself a new powerFC which will be tuned next wednesday.

I think B-Man has a high flowed turbo, but was more expensive and probably better than mine.

I had my turbo high flowed at ATS in adelaide... Cost me about 2k from memory (2 years ago)...

They're good if you're just chasing an extra 20rwkw, but if you want to make a decent amount of power, just put the extra $$$ to a new turbo. The housings (comp and exhaust) are too small to make big power.

Hi DREMEN, we have a R34 GTT with a GCG hi flowed turbo on it, makes 260 rwkw. Cost a bit under $2K.

Hi skyr31, our hi flows from GCG have all had;

The compressor wheel replaced with a larger one

The compressor cover machined to suite the larger compressor

The turbine replaced with a larger one

(stainless steel replacing the standard ceramic)

The turbine cover machined to suite the larger turbine

A larger diameter shaft

Larger diameter ball bearings

All the rotating stuff micro balanced

New seals fitted.

So basically everything that wears is replaced, so it is almost like a new turbo. Much stronger with the larger shaft, not ceramic turbine and larger balls. Higher flowing due to larger turbine and compressor. Best of all everything bolts back up to the turbo as per standard.

There is also an upgrade path, if you want more power then they can replace the compressor cover with a larger one and/or the turbine cover. Much cheaper than buying another turbo, particulalry when you include the cost of fabricating parts to fit non standard turbos.

Hope that helps.

Hi TT said, "GCG stage 1 hi flow turbo requires 22psi to make 450hp at the engine, as stated in a previous related thread."

And I said that's not quite correct in the "previous related thread".

We have one on an RB25DET that makes 260 rwkw at 19 psi. We also have one on an RB30DET that makes over 300 rwkw at 20 psi. On a properly set up engine it does not need 22 psi to make 450 bhp. On a badly set up engine it might.

The engine has way more to do with it than the turbo.

Hope that helps clarify

Hi macka, when you post "The quality of the turbo is not affected" your not saying that a "sleeve bearing core" is as good as a ball bearing core are you?

Sorry, but you get what you pay for. Plus the prices that appear on websites are "Recommended Retail Prices". Ring up you might be pleasantly surpised, I quite often am.

Hope that helps some more.

    • I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
