Hello,
On the straights my s14(SR20DET)zenki is okay, but if I corner smth like 20-50+ yard/meter radius corner and I go agressive on the throtle the car starts limping. By limping I mean that the rev's go up a bit then fall down, again up and down. This repeats until I get to the straghtaway. This is going on approximately in the range of 2700-4000rpm.
One more manifestation of this problem.
I was doing donuts. Occasionaly there gets fuel in the exhaust=bang, but once there was a bigger explossion in the exhaust. RPM's dropped, and for ~4s rev's had no response to throttle position, even if I fully depressed the gas pedal engine stayed idle. I've looked at the oil pressure gauge immediately this ocured, which showed 30psi the whole 4seconds. Thankfully engine recovered.
Upgrades after which this problem started:
515cc injectors yet still no tune;
300+LPH custom fuel pump;
Cometic head gasket;
Apex'i AVCR (set at 7 or 11psi)
t28 turbo started having shaft play;
3" free flow china exhaust
Engine head overhaul+all new gaskets
Upgrades before the problem:
4puck ceramic clutch+twin pressure plate;
Trust small FMIC
Apex'i BOV
I think I had half a fuel tank, so this couldn't have been be the problem(I hope).
