A fully water-cooled turbo (Comp CT3 5862) to avoid having to run oil lines.
More power from less boost would be better for our FA20 with sky high compression, no? Especially for us guys that can't run E-85. 94 is all i get here good gas but doesn't take timing like e-85 would.

If you have a good A/W intercooler you could possibly gain more efficiency by using gigantic intake cams to increase boost pressure but decrease dynamic compression. Higher manifold pressure means the intercooler sheds more heat and you get denser charge. Of course the supercharger power consumption has to be taken into account but I think at higher boost levels the cooler temperature should help more, especially with high compression ratio engine where the extra heat and pressure affects things more.
