I'm on the same page at the moment. Looking to upgrade now too...

I need -

Turbo

Clutch

Injectors??

Air flow Meter??

Have -

ARC cooler

Front/Dump pipe

Fujitsubo catback w/hiflow cat

Power FC

Oil cooler

Bleed valve

What sort of highflow turbo are you guys using/looking at. I see so much variation in price...

Turbo: I would go for the high-flow option. There is a heap of info on here about the results people have got with these. Personally I had mine done by MTQ in Brisbane, no stuffing about with flanges etc but did need custom lines to clear a bolt. Similar to the GCG one I believe. Set me back a bit less than $2K from memory.

Clutch: Can't speak for the Exedy ones. I have a Jim Berry/RaceClutch 5-puck "carbotics" clutch and it's very bitey, annoying and noisy in a traffic jam but great on the track or open road driving.

Injectors: Nismo 480CCs bolted in fine but I have read the bigger Sards for the Z33 fit now too in the Neos.

AFM: Z32 meter from a wreckers worked fine after we worked out the wiring!

Boost control: What are you using for this? Bleed valves suck, tried one and it was ok but a bit variable and did spike. In the end I just used the boost control kit for the PowerFC and got a good result, nice flat boost curve.

On the radiator issue, I was getting high temps on the track after about 5 laps but things improved heaps with a proper radiator flush (i.e. take it out of car, send it away etc) and use of Redline Wetter Water or whatever it's called. Don't know how it'll go on Tuesday in the 35 degree Ipswich heat though....

I did have some miss and traced it to one coil - did the Araldite trick and moved it from no. 6 to no.1 cylinder and no problems since - left the coil cover off. Complete reliability (TOUCH WOOD) except for a water pump that needed replacing and the usual power steering leaks.

The powersteering leak is annoying isn't it. I am going to have a good look at that system one of these days.
