Don't forget the $5k + that you will need to drop on brakes, tyres and suspension'.

But everyone on facebook groups just want loads of power on cheap tyres, stock LSD so they have a reason to whinge about no traction and how when they roll into 3rd their wheels spin.

If you can settle for less power, a low 300kw rb25 is a lot cheaper to build/run reliably than a 400kw one.

You can even skip the whole rebuild the engine drama if you want to (head gasket is probably a good idea along with better valve springs if you are running decent boost), lots of cooling (engine and oil) and stick to e85 or add wmi for safety when going harder on it.


This. Achievable without going e85 ? I think i can live with 270 rwkw :) and a long lasting stock motor!

I can't see why not. My setup was the same (excluding forged internals), it was so long ago, but I think it was about 270-280rwkw with the GT35r on a chinese manifold at about 16psi.

Lasted for 2 or so years before the engine upgrade. I thrashed the crap out of it too, but maintained it very well.

No dramas with the engine itself when my builder stripped it. The only issue we had was a crack in the manifold which was to be honest, expected.

Not to be a dick, but seriously, have a search on this forum. There is so much information at your fingertips. It was a goldmine when I was in your shoes.

Hmm wait. .. Im already at that power goal. I meant to ask if it's possible for the stock motor to last without an internal upgrade at that power level without going e85.


Yes, but e85 makes for a decent amount of extra safety for not a lot of extra effort/cost.

      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.

      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.
