hey guys,
ive got a 1988 Cefiro, has Rb20det, im currently running a HKS 2530 turbo but lately its been making a weird high pitched wistling noise, the turbo still boosts fine, but just earlier on today i took it out for a run and the the car started boosting fine then the power just cut off completely then back on again. it wasnt stuttering like it was a sparkplug problem so im guessing it could be the turbo wearing out?
the car is running bigger injectors (unsure of size, but runs about 66% at 1bar)
Tomei cams (again unsure of specs)
2530
Z32 AFM
3core radiator
oil cooler
FMIC
Power FC
and few others
just wondering if it would be my turbo, or something else. havent owned an RB before, only a SR20DET and a 13BT.
if it be worth rebuilding it or going for something bigger?
cheers guys
