Hi Wally
My Subaru motor came with a 240 mm clutch, I thought it might fit into the G50 bellhousing, no way.
Talking about stronger transmission, when I win the lottery I would love to fit one of these, the same people that make most of the gear sets for other manufacturers and are supposed to be stronger than Mendeolas
