i have been told of people having problems with fuel and boost cut due to fmic while using a stock ecu.

any help appreciated.

I've got the stock ic and recently ran 14+psi (15psi spike) no fuel cut issues.

I think if the ic is sized very well the extra horsepower potential may exceed the Air Flow maximum allowed by the stock ecu. More hp = more airflow = ecu dummy spit.

A big ass ic will create some lag if its oversized for the turbo and reduce overall flow efficiency. If you are running an ic rated a 600hp and you have a 300hp turbo you might make less power than stock AFC or not. Having said that at least if you decide to circuit race you will keep the power at maximum all day.

rev you make a good point that alot of people dont really under stand. having the biggerst cooler isn't great if you only want say 3 or 400 hp my cooler is (core only) 500 x 280 x76 if you look at most of the apexi etc coolers they are are similar size untill you get up to the big one for 600 hp +

Yep, sounds like you have a very sensible sized ic megs. Building a "whole" performance package is the best way to go. Make a plan out starting with what sort of measured performance you want and design the car around that concept.

If you want a turbo that can wack out 200rwkw then get the kit that will do that with the best efficiency and you will get better mid range power (what is needed on the street).

I very much agree, howeva a big ass intercooler looks SIK! You know how much i'm into looks Megs! :)

The restrictiveness of the IC can also relate to its cooling abilities though right? I mean a very unrestrictive cooler may not cool very well cos the air goes through too quickly??

      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.

      Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.

      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
