I agree with having a blow proof bell housing.... I have tried both alum and steal flywheels back to back in my car. A while back I chipped a tooth on my stock steal flywheel. It would still start, but made a terrable grinding noise. Unfortunatly, I had to replace my starter and flywheel. It happened after a hot start with bad fuel and the timing too high. "kick back". Any way, I bought an alum flywheel to replace the steal one.

After changing I could notice a little difference in acceleration. Motor did spool up quicker. I couldn't pick up on any other differences. Only positive gains for me. I didn't notice any braking or downshifting or off the line differences. I would go alum from the get go if i were you. JMO
