First the obvious stuff an induction kit and sports exhaust, FSE fuel boost valve, fast road profile cams, port polish and gas flow the head. A remap will improve things also but this is best done after other mods are carried out. You may also find that a lighter flywheel will help acceleration. Don't foget weight reduction either - a nice carbon fibre bonnet will help this. I'll ask a couple of 330 owners I know what they did to their cars - I'll report back.
