So I'm on a quest for a late model turbo and carburator. Since the carb in turbo in my corvair are the wrong type. It will still work, but I'm not getting the boost I should from the turbo. My mechanic tells me if I get a late model impellor and housing and keep the early model turbine, I can get the boost I'm supposed to, but get it soon in the power band. So I'm on a quest for the carb and impellor. Hopefully I'll have the parts I need soon.
