i jus installed an fmic and a boost controller, my car i an r32 gtst, with rb20det, standard injectors and pump, done 89,000 km's and the engine has been perfect for me besides having to change my fuel filter, but something strange is happening now since i put in my boost controller, was running fine on 12psi before it put it in, and with only and extra 1/2 psi it startes to wind slowly, then it clicks and then the power punches in, some times it feels like its not getting enough fuel too, jus wandering whether my pump cant handle the power or if its just out of tune, i plan on puttin in a walkbro pump asap, any other idea's?

What sort of boost controller?

Drop the boost back to 12psi and see if the car runs as it used to. If not then try removing the controller temporarily and see if it runs properly.

Just a couple of ideas before you spend the cash on a dyno run.

Is it spiking? It could be spiking causing a lean condition, resulting in the flat then kick feeling.

Thats if I've interpereted your post correctly.

EDIT: I still suspect the std pump is on its last legs. Being 10+yrs old and all.

At around 80,000km's my std pump was right on the limit at 12psi.

If you can find a cheap $35 power run then do it.. I wouldn't be spending $80 on a simple 1 minute power run. :)

That $80 can be better spent on a new pump, as after all... if you are like the majority, we all get the bug, end up dialing more boost, ecu, injectors turbo.. Money permitting of coarse.

I've managed almost 10k worth of mods in the last 2.5years while I've been studying full time at Uni. :P

6k was spent silly as I didn't 'really' need the rb30det as the rb20det was perfectly fine. lol

      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
