The InlinePRO stage 2 turbo kit is designed for top end horsepower. The manifold is designed to fit a turbo as big as a GT40 ( however, with modifications you can fit a GT42R ). With 3" mandrel bent polished aluminumc charge pipes, and a 3" downpipe, this kit is designed for max horsepower. We have seen up to 700rwhp on a Precision 67/65 turbo with this setup on race gas, and over 500rwhp on pump gas.
The turbo manifold consist of schedule 10 stainless steel, along with a cast stainless steel elbow for durability. Along with the manifold is a true merge collector to increase exhaust flow.
