Gingas,What are 404's.Yes it does depend on $$$ you have&willing to spend.N/A is more reliable &you will get more respect on&off the track.FI will produce more power but you'll have to dig deep in pockets.Nos will give you instant power but motor won't last long.I recommend if you want FI go purchase a Eclipse,EVO,WRX or something already Turbo'd and turn up the boost.I use to own a 90 Eclipse GSX&man it was a lot of fun at track launching at 5000rpm runing 14'9's stock.HP was rated 195hp at flywheel.I never broke anything.Just a suggestion buddy.Good luck!
