If the clutch is worn, then I would try to get a lightened flywheel as well. The flywheel allows the engine to rev much easier...and its great for heal & toe action. As far as power mods I would stop there. I haven't got an upgraded ECU yet, simply because I've heard too many horror stories about them. And 10hp for the ECU doesn't justify it for me. These mods make the car a lot more fun, but don't count on being able to stomp Z28s. After you're done with power, I would focus on suspension and brakes. Jack H '92 n/a
