selling my rb26 race head, i changed direction with my engine, after experienceing electrical problems with the gtr putting it in a workshop for a very long time and after alot of thinking deciding to change a few things, so hence the sale. i had a new head built for my new setup.

seen about 1500-2000km driving and dyno runs

was part of a setup that made 565awkw @ 21psi on pump fuel, so the head is good for it and is really really strong.

looking for around $7500, which is merely half of what it cost to build! needs to be sold asap to fund new setup.

Parts list:

Ferrea 1mm oversize stainless valves

Aftermarket valve guides

Apexi V-Max SPL springs, retainers and buckets

Apexi V-Max SPL 280 deg 11.5mm lift cams

Tomei camshaft stud kit

Trust cam gears

New stem seals

whats been done to the head:

Ported intake + exhaust runners

Profile guides

Polished + cc'd chambers

Unshroud valves in chamber

Flow benched and runner flow equalised

Steam hole modifications/water gallery modifications

Clearanced for high lift cams

Drilled for 1/2inch head studs

Flow figures:

      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.
