Hey guy just have a quick question and need some help cause dont no wats wrong.

i purchased a hypergear PU turbo and installed all perfect no problems.

the problem im having is when i hit boost it just doesnt make any suction or turbo sound and if it does its really low and flutter or even my bov thats plumed back doest have the release sound and im hitting like 4 psi.

With my stock turbo i had before installed which is a S1 turbo it had suction turbo sound and flutter and release pressure of my bov and it was plumped.

i thought it might be the lag abit on it thats why it needs to hit more RPM but still nothing just a faint lil sound but my stock turbo sounded crazy :).

ive got alloy intake pipe not the stock rubber one.

Any help would be great cause cant take it to hypergear a lil to far at the moment to get there so just thought id ask here if anyone had come across anything similar.

Just getting checked now on dyno,was thinking big boost leak aswell.....had tryed the preload 2/3mm but still nothing last night still hit boost like 4 psi but not thrashing and that normal..,i checked everything in oil feed line which oil was coming out as ussually turbo spins freely and great and minimal shaftplay...has to be big boost leak for sure cant think of anything else.

      What brakes on R34 GTT(Europe)

      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.

      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.
