Another Garrett build, with Garrett GT30 Turbo, V Band Manifold, Courtenay Klasen Cams and Inlet Manifold, Engine rebuild, 90mm AFM, injectors, 3″ exhaust; all the usual requirements for a Garrett conversion, previously mapped by us and making a respectable 490bhp; brought in for checking now its a little cooler. Up 13bhp to 503bhp due to the lower temperatures.
