no, the two clutches and flywheels are totaly different designs. even if you kept the big flywheel with mods, you would need to find a friction disk with the correct spline for the small
trans, that may need to be custom.the by far easiest option is a heavy pressure plate and the b2000 flywheel and setup. bare in mind, all the fe3t guys with mx5s use that same setup, and so do all the turbo bp mx5 setups. its not that bad, i'm just crazy fussy :-)
