Thank you gents. I will call Dennis on Monday re: Poly motor mounts.
A turnbuckle is a good idea. A major and important mod for my FWD Cooper S with a transverse engine is an upper engine support bracket that bolts on between the block and the bulkhead. Necessary when I upped the power from 68hp to 119hp!
It's worth investigating as far as where on the fender wall or engine bay a brace or support can be mounted without tearing the fiberglass apart from the torque twist of the motor.

Cheers!
