For this conversion using our new V Band Cast Manifold the brief from our customer was as close to 500bhp as possible but with usable power. We opted for a Garrett GT3076 turbocharger. The car also has our full height VXR intercooler, steel rods, Courtenay Sport High Flow Inlet Manifold and 76mm full exhaust system.
