I know how you guys like pictures :cheers:

The blue one is the hydraulic profile I grind on and the red one is your GTR cam. This graph is what is on the camshaft. You can see what needs to be taken off. The little closing ramp on the blue one demonstrates a very good hydraulic profile made by nissan to prevent fast valve seating and potentially necking the valves.

This one is to give you an idea of what happens at the valve. The red (GTR) profile is smaller because it has had some clearance taken off it. So you can see the gains to be had from this grind. I don't have a GTS grind on the cam doctor (or couldn't be stuffed finding it) but rest assured it is quite a bit smaller again.

Luke, I've been slack and not on for a couple of days but will hopefully get them away today.

Ivan Tighe's huh, had some cam work done there before when it was near the city. Very impressed with the rep and the work done.

As for Qld, give me ummm ......3.5 months and Vic can go to hell, or antarctica, whichever is closest. ;)

      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)

      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.
