interesting mild turbo setup

Meh, draw through systems suck and turbo technology has come a very long way since those things were installed on factory cars. Corvairs had a similar setup. A better setup is a newer CSU blow through carb, or similar, with a modern turbo. Dual ball bearing, ceramic ball bearing, billet cnc compressor and turbine wheels, cnc housings, are just a few of the reasons turbos are making gobs more power than they used to. Some things don’t need to be brought back from the pick a part yard. As always everything IMO.
