Cliff,

Thanks a bunch. That is the kind of info I have been looking for.

I do think the Turbo II 13B will make make more than 200hp at 5psi of boost.  I have 2 reasons for believing this.  First is that Tracy Crook and Bruce Turrintine claim to be getting almost 200 hp normally aspirated simplying by upgrading to the 4-port intakes.  Second, the RX-7 guys generally accept that putting a "cat-back" system on a stock Turbo II will give the car about 235hp. (not sure if that is at the wheels or flywheel).  Nonetheless, your analysis is invaluable.

Like Paul, however, I plan to try out the stock '91 turbo charger first and see how it goes.
