A nice well-reasoned approach.  Refresh my memory... are you planning on using 
the stock Mazda turbo and controlling the internal wastegate, or are you 
planning on an after-market unit with separate wastegate?  I've got a stock 
turbo from the first 13B that I purchased and it would be pretty simple to 
hook it back up.  The only problem with it is that it's really heavy.  I'd 
prefer an aftermarket turbo and throttle-plate style wastegate (as opposed to 
a Delta-gate or one of those poppet-style units.)  That being said, has anyone 
come up with the real spec for the appropriate turbo, ie, T-what? turbine 
trim? compressor trim?  Lots of questions......
