recently i have brought a R33 Gtst, last night i was out giving it some shit when suddenly it started poping at high rev range and not reving out. i read about similar problems on this site and have changed pugs, checked coil packs, check hoses and intercoller sleaves. nothing has solved the problem was thinking it may be turbo related? and help would be very appreciated!

Mods include

dump pipe

3" zorst

fmic

safc (not tuned)

9 psi

Apexi pod

it could be, but safc has been in for a while and all things have been fine, could it be air flow sensor? i didnt see any cracks in coil packs but should i have tapped them anyways?

there is a bagillion threads on this

my brothers skyline did this

my skyline did this

coilpacks both looked fine, but replaced with the spitfires and the problem has 100% gone.

swap coilpacks with someone of same car / coilpack types

or just buy new ones

there is a cheaper option of running your external DIY mismatch of ignition system, thread here somewhere

edit: if you dont know someone with same coil packs, what you can do is drop the gap on your plugs. bring em down a good few tenths of mm. say from 1.0mm to 0.5mm. if this improves the misfire situation, then you know you have weak ignition. it may 'fix' the problem, but if you crank up the boost you will run into the same troubles

also a pro of getting spitfire coilpacks, i got my fuel economy from 13L to 11L. they'll be making me money soon! (2 years haha)

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
