The engine is an LS6, mated to a Porsche Boxster 6 speed transaxle. I built a custom chassis using Miata front and rear suspensions and brakes. It uses a remote electric water pump, mounted in the front by the radiator. I’m using a drive by wire system from a Chevy truck to eliminate the long throttle cable.
I had to move the rear wheel wells backwards 3” to center them up on the longer engine and transaxle, and I had to move the fronts forward 9.5” to fit the Miata subframe and me! All four fenders are flared about 3”, the front chin is lowered 2” giving it a more aggressive “mouth”, and the rear facia is lowered 5” to cover the back of the transaxle.
