Courtenay Sport mapped Garrett Conversion. The brief was to achieve 500bhp from the mapping and the customer had prepared the car with a Garrett GTx3076 turbo, tubular manifold, 76mm exhaust, 90mm air flow meter, 680cc injectors, High Flow Inlet Inlet Manifold, Courtenay Klasen cams, Forge Race Intercooler, Mocal Oil Cooler, Sachs Uprated Clutch and Uprated Cera Metallic Paddle Disc and Lightweight Flywheel.
