Kent flywheel lightening

Depends on what form of motorsport engine is going to be doing - if the flywheel is too light engine won't have torque to pull up hills. Have taken big enough chunks out to leave only a bit of extra meat around the clutch mounting face- this was for drag racing and used a paddle , sintered bronze plate so probably took well more than half a kilo out.  The strength of the plate is not so much an issue as how it affects the engine application.

My 1st engine swap in my mk1 escort from a 1100 to a 1600, is i forgot the clutch spline was bigger in the 1600 i put the 1100 clutch and flywheel in there.... went like the clappers for a few days till the clutch exploded ina big way !
So yes you can fit other Kent flywheel to 1600 . I was told it's a similar weight to a Lotus Escort flywheel. .
