Just out of curiosity. what may be any benefits or drawbacks of going with either engine? What should be done to an efe engine in preparation for ~200 or so rideable hp (td04 or vf23 or vf24. I got that part figured out...). Do they have forged pistons already good for 200 or so. Are there magic suzuki swap pistons out of another bike to use rather than 900 dollar turbo pistons. that sort of thing.  Or is there any reasons why a person should just start with a bandit motor to do this w
