ok iv had this car for like a month or two now took it to the track and dynoed it and i knew the clutch was slippin. so today i put my car on the lift just to check it out. I really looked at the tranny and its a w58 n/a tranny. the guy i got it from said it was swapped but no such luck. so my clutch is slippin with a w58 and Im going to do a gt35 kit prolly pushin over 400+tq so my Q is should i stick with the w58 or go r154. also i have the 4:30 rear open and i really wanna do a lsd. I cant really find a street clutch that says it will hold over 400.
