uh i don't know too much about cars, but this post confuses me =P

you're talking about replacing the engine right? which defeats the purpose of having a gtr engine in the first place?

if you mean boost, the standard reply i give anyone is 14-15 pounds before the rings/valves etc start taking a beating. If you put any more through you're going to need to upgrade a few bits, not the whole engine

IN TERMS OF STRENGTH..

early r32,r32/33/34 same n1,groupA.

also a old 200k old 32 or 33 block is stronger than a new n1 block. due to the weathering proces of heating up and down for the last 15 years.

you wont have any issues. unless your making in excess of 1000hp. on a block thats been bored out more than 40thou.

splitting blocks is usaly the result of localised hot spots in the cylinders. thats where block preperation comes in to it.

no that's cool, i've never seen anyone concerned with the block before is all, i've seen some crazy power put through those engines, never thought it was an issue =P

i started being concerned when the mechanic told me and was even more surprised coz the place i went to is suppose to be one of the best and everyone told me to go there that they knew what they were on about....

but thanx pplz for the replies excellent people on here.

I ran 2 different blocks a one stage, one was sleeved and the other was an older block from a r32, both have put in excess of 234234 grasshoppers power = wheelspins at 150kph (semi slicks) if I dare to jump on it.

But for general use I can't see problems with RBs in general unless u got other probs ie loose rod bolt of disintegrating big end bearings yadada-yadada, you know what I mean.

u do need to worry about your block if you constantly do 10000rpm launches...

or if your bore your block too much...running stock capacity, your block is pretty much bullet proof..cant see the point of buying a N1 or group A if you dont use your car for drag racing

      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.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
