Car Hesitates When Accelerating? R33

Hey guys,

I have a r33 gtst rb25det. My car idles and drives under load fine. However at low revs when the car goes around a corner or bumpy surface - eg a pot hole or bumpy intersection etc, the car hesitates for a second and then starts pulling. Basically it doesn't accelerate smoothly after going over a bump etc but rather hesitates for a sec then hits all of a sudden - sort of a jerky transition if it makes sense. However once it has done it it continues to drive fine. only does it when the road surface bumps the car or when I turn. Any idea's on what it could be?

So far ive figured something must be getting bumped or knocked causing this hesitation / jerk, it usually occurs round the 2-3000 rpm mark.

Car spools up fine but sometimes hesitates (corner or bump) - only for a second or so though.

Any help is much appriciated!

Problem sorted. Before my Power FC was installed, I had an SAFC which you have to splice into some wires in the ecu loom to install it. Some of the connectors were loosening and wires were just showing and touching sometimes when i would turn right or go over bumps. Re-connected the wires with new joiners and problem solved! Thanks for the help guys!

      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
