thanks for clutch information. about tbk's car, i've always wanted an sc since 91, when i took one for a test drive. couldn't get the dealer to come down to my price. then in november my wife hit a 20k jackpot on a slot machine, so she told me to go get one. i orginally wanted a white one but his red one was very clean so i bought it. a month later i was having a time getting it away from by three teenage sons, so i bought a project 90 with several mechanical problems, now that i got it running i'am trying to do some history on the car, because it seems much faster the the red 93. it appear to be stock except for the resonator or muffler near the transmission has been replaced with a y pipe. do you know if that makes that much of a difference? the only other thing i can thing of is the gear ratio. the 90 has 228k and the 93 now has 103k.
