Ok, I am going to go JDM STI 2.0L EJ20.

On that thought, should I go v7 or v8? As I understand it, the V7 has forged pistons, but the V8 has better flowing heads, higher redline, and better crank. Also the V8 has higher compression.

I also need to determine which turbo will work best for my application. I don't mind running a custom turbo and I would like an external wastegate. Is it worth doing twin-scroll? The header design I have in mind will be less than 18" from the exhaust port to the turbo and will be equal lenght.

From the turbo, I will go directly into an air-water intercooler and then directly into the intake (flipped). There will be very little bends and very look piping.

I am also considering using the same Leaded 110 Octane Race fuel that I am currently using. Either that or E85, which ever work best.
