Decent, less restricted headers spaghetti headers jetted to suit, cans on there own will do little. Lighter flywheel and lighter or slipper clutch will start to realise the potential of the 2 valve engine. Decent suspension setup standard or better quality and sticky tyres. Maybe a decent steering damper. You can do more to the engine but can get expensive but if money no object 944 kit, flatslides, head work etc the list can go on... Carbon wheels, everything lighter.
