Hey Guys,

I am about to get my freshly rebuild motor and winter is coming very fast.

I had set a plan for the breaking of the motor, I wanted to drive it about 4000km normaly, pushing it once in a while and then oil change. What else should I worry about?

The question is that I dont know if I should break in the motor before i put her to sleep for the winter or wait until next year to do that? What would be the best?

Thanks alot

The bulk of the wear happens in the first 50km. It's vital that the first time the car is started it gets warmed up to operating temp and then loaded up on the dyno, so that combustion pressure can seat the rings properly. The key is load, not revs.. I would progressively load the engine up at 2500 - 4000 rpm.

After that's done you can start exploring high load high revs a bit - personally I wouldn't redline a new motor but that's just me.

Most of the wear will happen straight after you fire it up so 4000km is too long for your first oil change. Put mineral oil in it, drive it for 500km, then do and oil and filter change with more mineral oil and do the second service at 3-5000km. After that you can probably go to synthetics.

That's just my opinion though.. I don't build motors for a living :pirate:

      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
