Hi, will soon be upgrading to a r34gtt stock mount. I was wondering if there are any modifications to make it fit, or is it a strait fit?

And to get to the r33 stock mount, can it be done by removing the wheel guard, or does the front bar have to come off?

And with the r34gtt cooler on the r33, is there a notible difference while running a bit more boost, such as 10psi?

will appreciate any helpful replies

Thanks,

I installed R34 Cooler on mine,

with the front bar off very easy to do,

since the front bar on have 4 bolts holding it, very easy taking it off.

its really a bolt on job.

performance wise, no idea, only when u increase boost!

Straight bolt up. No mods required.

Make sure you have the r34 duct too. To install the duct, the front bar has to come off. This requires a trim to get the bar back on. You'll know what I mean.

No noticeable increase in power.

What is a duct?

Can i use r33 duct?

Must be some air duct to run from the stock hole in the bar to the cooler.

When I put my R34 cooler in, the bottom of it sat much lower than the stock R33 one. So much so that it's pushing the lower shroud down and creating another airduct under the bar!

I don't know how much difference that would make, but to theorise on your other question about performance, the R34 cooler has bigger in and out pipes on it, and the core is thicker. In theory I beleive this means you could push more flow through it. Dunno if 10psi makes any difference, i'm still running 7.

Considering the R34GTT's are 206kw stock, i'd say that this cooler would be good for at least that. I'd also guess that your intake temps might be *slightly* lower under load due to the increased surface area of the taller and thicker core.

I'm going to mount a JayCar temp probe in my intake somewhere and monitor the temps. If it all seems good, then i'll run it up to 10psi.

      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.

      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
