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)

If the prototype adapters work ill send the CAD files out to mill from billet aluminum.
I'll be using a MegaSquirt system I picked up. Still have to modify it for COP. |

Still have to modify it for COP. When you get to the "ill send the CAD files out to mill from billet aluminum" part of this project my brother works for a machining company, programming, running and supervising their mills. They have at least 2 monster 5 axis mills. I don't know if he can save you money but it is worth asking. Jim |
