i have a r33 with some work hi flow turbo, intercooled ect, and when im going it spins into second awsome, when stopped spinning in 1st when changed to 2nd the wheel spin stop and the clutch just slips, even after a drive once out the car the clutch smell is still there even though it has not seemed to be slipping, is it just because the clutch can't keep up with the mods and its time for a racing clutch since its a standard clutch?? shmiddy
