Defined Autoworks specializes in rotary powered cars. This 1997 Nissan 240SX previously had a three-rotor engine but someone offered the owner a price he couldn’t refuse. So out went the three-rotor and in went a LS1 from a 2002 Camaro SS. The engine runs a LS6 intake, ASA cam, LS6 valve springs, LS7 lifters, and 1-7/8 Hooker long tube headers. That engine recipe is good for 393 horsepower and 360 ft-lb of torque to the wheels. But sheer power wasn’t the ultimate goal for this Nissan, it was dependability. This car will be competing in endurance racing. You can read more about the build of the car and it’s previous engine swap here.
