Valvetrain and drivetrain would be the focus...exhaust and intake work are a given on any modded car.
Camshafts, rockers/lifters, valves/springs, lightweight flywheel, and reagearing the rear end is where I'd first spend my money/efforts for building NA with the FA20.

Quick FYI there engines don't make any more power after roughly 7800 rpm they die out. You can not do cams that are even remotely worth while without changing the stroke and pistons to prevent them from kissing the valves.
