I just finished designing a sbc single turbo kit for sbc. It is all stainless,tig welded, 1/2" thick flanges, and was designed to directly for gm muscle cars, but fits tight,so could easily for other applications. They will be available thru me at a discount . I can sell the turbo manifold kit alone for $400 or headers 50mm wastegate and BOV for $600. Here are some photos, they will be available very soon, let me know if your interested or have questions. Jerodkirk@gmail.com
