Just scooped a NOS Holset H2C for a single turbo setup in my 57 Chevy 3100 Pickup... I was sure that I read that this thing had a 23cm dual scroll housing, which I could've worked with, but the 28cm housing that actually came on the turbo is WAAAAAY too big for a dual scroll street application on a small LS 5.3 stock internals, LS6 cam and springs!

Has anyone had any success finding a 14, 16 or 18cm exhausting housing for the H2 series turbos???

Any experienced advice is greatly appreciated.

Thanks
Mike
