Mike R33 GTS

Yeah, I have dropped the boost off a bit. I've got timing issues now, I need to get the spark plugs re-gapped but if that doesn't fix it I will need to get a set of spitfire coils put in. I'm going to put in a Hybrid GT intercooler in the next few weeks, gonna give the install a go myself and then get a PFC after that. Cheers, Mike.

Hey, Not sure how much this will help but I've got a 95 series 1 R33 GTS-T with: K&N panel air filter 3 inch turbo back exhaust Bleed valve (with the boost set to ~11 psi) I got the car stock from Japan and had the guys at Hyperdrive in Perth, recommend and fit the parts listed above. The dyno, which was done before the air filter was replaced, came out at 228.3 HP. It really needs a Power FC to be fitted to sort out the power curve but it might give you something to compare with. Maybe go back to Hyperdrive and have a talk with the guys down there, btw my boost dropped off as the revs got higher too.
