Stage 3* is the final stage using the standard factory K04 Turbo. Over and above the Stage 2 parts (Front Pipe and Induction kit), with the Stage 3 we are looking to fully optimise everything around the turbo to fully maximise efficiency, so a huge Pro Alloy/Courtenay full height intercooler is installed complete with large bore pipe work and hoses, which whilst keeping the inlet air temperatures very cold also optimises the flow from the turbo through to the inlet manifold. Next a 3” free flowing de-cat section is fitted to compliment the high flow front pipe removing both catalitic converters. With these installed the car is remapped on our dyno optimising our Exclusive Courtenay Sport software to take full advantage to achieve maximum gains from these components. Power and torque graphs.

Power Gains to 340-350 bhp Torque 380-395 lb ft
