Hi people

i am relatively new to forums so bear with me if i get some stuff slightly wrong.

I am currently building a 30det with a 25de head. I have gtr valve springs i am going to slap in(cause common knowledge is they float, according to my research)

I have full rebuilt the bottom end, crank collar, n1 oil pump, degalzed, new rings, polished and rebalanced crank, new bearings all round, new waterpump.

I have just managed to get a 25de head the other day, looks good but am going to take it to the engine shop and get it checked out to be safe anyway, can't imagine anything more worse than slapping it together and wondering why i keep chewing through head gaskets.

I have done everything else to motors bar one thing: headwork.

Now my question is this : the head has come with 20det r32 camshafts, and i am wondering if they are going to be any good, or if there is any much point to having them. I have looked up the lift specs:

http://www.tomeiusa.com/_2003web-catalogue/e090_camshaft-specs.html

the cam chart seems to say that the only difference is the exhaust cam. Its lift is .5 more and its degrees is 8 more. Is there any real benefit to this? or would i be best to just get some 25de cams and chuck them back in?

am i wrong or am i reading the chart right? cam work is something i havent dabbled in before, never been brave enough so any help is appreciated

thanks guys

      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.
