Hello, I am the new owner of a 2004 Hayabusa that I have purchased to use the engine in my 1959 Austin Healey Bug Eye Sprite. I have a lot to learn about the busa engine and can't wait to share with you all my progress. The goal for the car is just a fun toy for me and my boys to play with so it will not be built for track days or racing of any kind. The car tips the scales at about 1450lb from the factory so hopefully with a much lighter engine/trans setup and some lightweight wheels and disc brakes, I can get it to about 1300lb.
