I do custom Hx40's that are a direct bolt-on for these trucks - NO they are not hybrids and I can do 12, 14 or 16 cm housings. I can do 64 or 67mm turbine wheels and 60mm 6blade or 7 blade compwheels. When these are prepared you unbolt the stock unit and bolt these on, no other parts are needed. They work well up to 44 psi boost. I mainly do them for trucks I work on but have sold a few on Ebay. Drop me a note if I can help. Thanks, Mike.
