About the fuel...if you go for bio ethanol (which i personally recommend for future HP increases) think about the rubber sealings in bearings, fuel lines. They have to be tested to be resistant to bio ethanol.
About parts...HKS, NISMO, all build parts for turbo engines, which are stronger then they are light (big pressure above the piston). Strength is the main design demand. Lightness is not. And you need lightness.
I think you have to see what you can do with Honda/Acura parts...But that won't be easy.
Let me know what you have found.
