Hey guys, I have a 1993 R33 Skyline.
I recently had it converted to manual, at the same time, i had a full service (inc spark plugs), new timing belt and water pump (by NisPro).
The car has 3" catback exhaust, turbotech manual boost controller set at 10psi, VeePort BOV and a HKS mushroom air filter, stock ecu and smic.
When flooring it, the car seems to pick up nicely around 3-4000rpm, but once it gets around 5, the boost guage still reads 10psi, but the car seems to take noticeably longer to get to 7rpm than from 3 to 5rpm. I had a friend with a 32 drive it, and he confirmed, from 5000rpm i've got nothing!
The car isn't hesitating/stuttering/making funny noises, it just seems like it's n/a from 5000rpm onwards.
I'm wanting to work out what's wrong. Jez suggested it could be my coil packs. After reading a few threads on SAU about them, I think i'm going to try and find a working pair to test that theory, what else can i look at?
Thanks guys
Isaac
