I picked up this 2.4 six awhile back and I'm gonna use this thread as I develop the engine which will eventually go in my gold car.
I'm starting a little out of order, but too bad. (IMG:style_emoticons/default/tongue.gif) So I have this aluminum flywheel. No manufacturer stamps or numbers on it whatsoever. I'm thinking that it might be too light for a street car, so I may not use it. It's about 3lbs by itself. I've got a 914 clutch adapter (basically a cut down 914/4 flywheel that bolts to the outer edge) and that brings the total flywheel weight to about 10lbs. I want a streetable car, is this thing too light? Attached image(s)
