Get some high temp hose from pirtek just to be sure.

I've had my R33 for two weeks now and have come across a problem. Over the last 4 or 5 days it has become harder to start. Each time more so than the last. When it does start, it idles smoothly with no other hiccups throughout the rev range. I am the first owner of the car in Oz and I am wondering if the plugs are still for jap fuel (100 octane) and possibly fouled. Could it also be the AAC control valve or the bi-metalic valve? Any suggestions?

One other thing I noticed. The car will idle roughly (sounds like three cylinders) but as soon as I touch the accelerator it idles nice and smooth. Any suggestions?

HKS turbo timer for sale. Unsure of model but still working. Not compatible with alarm. Offers?

Love your avatar.

Thanks for the reply. Maybe someone else has some more info

Does anyone have an English manual for an "Ultra Speed Meter No. 4000?" I disconnected my battery and it reset itself. Little help please.

Is anyone using the Microtech plug-in ECU for thier r33 gts-t? How much including tuning? How does the car go?

HKS reach the same power level as garretts but at a higher boost level. (Typical japanese)

I agree. The only reason for a blow off valve is to keep the turbo speed up. If there is no blow off valve (or blocked), when the throttle is snapped shut, the turbo is still spinning really fast and producing boost but the compressed air has nowhere to go. This causes backpressure in the turbine and slows it down which in turn means it takes longer for the turbo to spool up again. With a properly fitted and adjusted blow off valve, excess air can be vented (or plumbed back) keeping the turbo speed up and lessening the spool up time.
