Guys done the search but not a lot about pros and cons (just problems)

Can anyone enlighten me on what they believe would be the best EBC for a GTR running twin -5s. Max boost will be 2 bar.

I have been using a PFC EBC and am not happy with it so looking for an informed change.

Thanks in anticipation.

blitz dual solenoid boost controller and make sure its the spec r version not the spec s, holds well up to about 36psi, profec bs2 is good for the money but if you got the extra cash you can get the blitz spec r version, i think they are like $450+ or something but correct me if im wrong,

cheers tony

why arent u happy with the PFC boost kit?

you set the duty, set the boost and drive

what more is there to it ?

Yup that was my theory to. May have a dud as it will actuate (you can hear it working) sometimes and other times not. Wiring has been gone over and seems ok, solenoid fires on 12 volt, ..... Just lost confidence in it.

Rather than risk a lean out due to overboost if it does play up another unit seems a safer option.

profec B is good and very cheap. the blitz spec R and spec S are pretty average in my experience. the blitz SBD ID III is not bad though. but personally I still prefer the profec B II. I have it in both my GTRs.

here is my boost curve from some time back. if you can get a flatter boost curve than that, well done! also note how sharply it ramps onto boost, but still doesn't over shoot the target. very hard to get a controller to do that.

Im also looking for a boost controller and was deciding between a boost controller or a PFC (ER34 GTT) which is more feasible anyway? And do we need to have a dyno tune after the installation of the boost controller?

That line is almost as flat as my boost line in the gtr running of just the wastegates (no boost controller at all)

Nice :D

      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
