I have a  problem with my '63 turbo charged Corvair.  I have not been 
able to  get the turbine to spin up.

The oil flow is correct, the turbine spins  by hand with a slight drag 
(I've been told that is normal).  I even  tried it without the muffler.

The one question I have is could the  turbine wheel or the turbine 
housing not be matched?  Do other years  have different wheels/housings?



The only mis-match that could really affect boost would be putting on  a late 
exhaust housing onto an early turbo. There wouldn't be much of a path  
through the wheel with that set-up. But, unless the engine was assembled like  
Johnny Cash' Cadillac - (different parts from different years) I think you  must be 
lacking a fully sealed exhaust system. Those exhaust leaks are  responsible 
for 90% of the boost problems I have seen. The exhaust would  rather go 
anywhere else than through the turbine wheel.
