if you wanted to achieve the MAX amount of power and have have an UNLIMITED budget, this is what it would probably consist of:
~Fully balanced, machined, polished crankshaft
~lightweight connecting rods
~Pistons that will put your compression ratio somewhere around 11.5:1
~Head to be ported, and polished
~Greg V's freak header
~2.5" downpipe, small resonator, and dumped from under the car
~Lightweight pulleys
~Fidanza Flywheel
~JWT Clutch
~3" custom cold air intake setup
~N60 MAF
~SR20VE injectors
~AEM EMS ECU
~JWT C3 cams
~JWT springs and retainers
Could also in the direction with ITB's, but I don't think I would go that way.
