Im in need of a few ideas guys...
Ive get an R33 GTST S1.5
HKS 2535
Turbo Back Exhaust
Blitz Spec S Boost Controller
PFC
Z32 AFM
580cc Injectors
Trust Front Mount Cooler
Nismo Fuel Pump
Now, im trying to run more boost, about 17-18psi and as soon as it is turned up more than 14psi it wont hold boost anymore, it will hit 17psi then drop of straight away to 12psi...
The items that have been checked are, Exhaust, intake, Blowoffvalve, AFM and tried various boost controllers but nothing seems to work.
My mechanic seems to think it may be the turbo on its last legs...
Any ideas???
The car has run perfectly on 14psi and i am only experiencing trouble now that i am turning up the boost...
Cheers
