Well last week after chatting to some people at Zcars I have decided to put a bike engine in and a full roll cage and go an have some track day fun.
Just finish off the welding and paint the whole car the original claret, roof as well.

Rip the rest of the mouse eaten interior out and a pair of bucket seats with full harnesses.
Engine has been bought (GPZ900R) and I have a chain drive to diff conversion sourced.
Has anyone else gone the bike power route?
Disk conversion for the front brakes is a must.
I'm going to mid mount the engine for better balance.
Any thoughts or things to look out for?
