Car: 1UZ V8 s13 Silvia with z32 gearbox
So i drove my car up to edmonton last night but on the way there and on the way back it gave me some wtf problems. I daily drove my car for 2 months on this setup prior and had no issues as the longest time i had driven it without stopping was to banf at about 3500 rpm in 5th for 120km distance.
So as i reach olds my car suddenly loosese power and feels like my fuel pump just stopped working but at the same time it wouldnt completely die. would reach 800rpm and then i could rev/drive it to 3000 rpm exactly and it wouldnt go past that. felt like my maf stopped working. while i was still rolling in neautral doin 110 or so i turned the ignition off and then on, let of the clutch and it started to work fine again. did it 4 times to edmonton as i was at 4500 rpm and 2 times on the way back when i was at 3500ish.
Only does it when driving for a long period of time at high rpm.
Drifitng non stop for 5 mins at 6500 rpm doesnt effect it either
Alternator?
Fuel pump?
Maf?
