hey everyone, just what to know what you guys think about my rebuild. I'm rebuilding my SR20DET S14 motor because I broke my head gasket. these are the parts I have so far.

Tomei Head gasket 87mm bore size and 1.2mm thicknessferria valve +1, valve springs, retainersCP Pistons 87mm with 8.5 compression with heat coatingBrian Crower proseries rodsDarton Pistion sleeves HKS step 2 264 camsTomei rocker arm stoppersARP head studs, main studsACL race main barings, rod barings

This car is still going to be a daily driver so I'm really not trying to make tones of power. Like to do some circuit racing track events. The turbo I'm using is a GT2871R .64 trim. I have Power FC already and Z32 MAF. 3" turbo back exhaust system. A question I would like to ask is would the HKS 264 cams too big? Will I loose too much power at the bottom? And another question is the head gasket. Is the 1.2mm thickness to thin should I have gotten 1.5 or 1.8? I would just like to maximize the turbo as best I can. I would like to make 400whp but as I see on some of the fourms that looks pretty hard to do. If anyone can give me some advice I would appreciate it.

i dont know about the clearance part but how much boost are you gonna run? and with this setup it sounds like you should be around 400whp ima be putting a s14 sr in my 91 coupe with sotck internals a greddy intake mani and a turbonetics to4e im hopping to easily make 350-400 on 15lbs with 550cc. my friend is making 320 on his s14sr stock turbo on 17lbs with big intercooler so you can see why i think ull make 400 with everything ur doing to the head

well for the setup that you going to do... i guarantee you will be pushing way more power, it depends on how you tune it or the person that is tuning it for you. the hks 264 cams are not too big you can daily driving with it...

Thanks guy, I'm planning on running 20 to 23 or so. I just got a Greddy intake manifold and a Pulsar 70mm throttle body so hopefully I'll be around 400whp.
