I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

Ok. This is our latest dyno result based on a ATR28G4 in a .64 T28 rear housing running on a build CA18det running 98 fuel. Car made 316rwkws at 24psi at this stage ( Note: see how the power curve is still rising. ). going to do a final tune in few days. This turbo would be making some mad power on RB engines using .63 rear housing.

ATR28G4 would be some thing similar to a GT3076.

CA's modifications: Forgied pistons, Split fire coils, Nistune ECU, FMIC, 700CC injectors, Z32 AFM, 256dur/8.9mm cams, Tomei adjustable cam gears, ebay manifold and 3inch exhaust. Every thing else not mentioned are stock.

That looks good. OP6 is still small. You need .63 rear. I can get one machined for for $250. But you need to make a new front pipe. Check That exahust place next to Trents.

The guy got EPAed and defected on the way back from SA. its going to be a while before it go back to the dyno. Hoo and by the way there are plenty of ATR43's progress. The laser cutters finally got our flanges ready. So just matter of putting them together now. should have 2x samples done by weekend.

Its similar sort of CHRA. Rear housing is different. It will be a.63 Rear housing. that we made our selves. I'm plaining to make 4 different types of CHRA with 2x different sized A/R housings. which are powered from any thing at 230rwkws to 330rwkws depends on driving ability. I will post some photos once I get the housings finished.

      What brakes on R34 GTT(Europe)

      By Dose Pipe Sutututu · Posted

      Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.

      Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      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.
