Hello! First real post related to my 1976 2002. This little car was picked up on BAT, and has a great engine with dual side-draft DCOE 45Webers, 10.5:1 Ross racing pistons, tubular headers, an E21 head, and a hot .302-degree cam. This is pertinent to my questions. I've gotten my hands on a nice Getrag 245 5-speed and want to do the full conversion. The car is going up on it's stands for a full brake system rebuild and a full front/rear suspension upgrade and refresh. Both sub-frames will be dropped. While I am in there, the transmission will be addressed.
I need input on the following:
Given the hot cam and higher horsepower motor, am I well-advised to go with the 228mm tii flywheel with something like the Sachs Performance Clutch kit? The car will not be a track car, and will be "fast street", at most. I'm concerned about the loss of low-end torque in the lower rev range due to the cam set-up, and wondering whether a heavier flywheel will actually help with that.
I do not know what is in there right now given the PO engine rebuild and stock 4-speed transmission. It functions fine with no discernible slip, but will be replaced with a good fit for the 5-speed.
I am tempted to stay with a new 215mm diameter set-up, and maybe a Stage 1 clutch upgrade, with a lightened, but not aluminum, flywheel. Thoughts?
