The engine is a ZX1 with the stage 1 Raceline setup with 180HP. It has the shaved head, Raceline TB and GEMS ECU. I just had the cage built by Chris from Competition Cages in NC. He is a one man shop that does perfect work and at a great price. I am in shock that most of the people want the car with the standard roll bar. I am willing to sell the car without the cage if a buyer wants it that way.
