N/A RX7 engine converted from turbo running twin carb. Will give a9k rpm, 230bhp and you can pick the engine up on your own its that light. Incredibly smooth and easy to install as it can be mated to your existing box.

I can put you in touch with a company who do this for a living, they put one in their escort mk2 rally car and it blitz'z everything in sight, and its classed as a 1300.
