And i never said you were incorrect in saying you could turbo the FS-ZE. I said that it would impractical and highly advised against. Corky Bell is an awesome source of information, but boosting a high compression engine requires some pretty extreme engine management and tuning. In fact i'm pretty sure it states that outright in his book on turbos.

This is the first time I've read this FAQ so I apologize for the late post.
I like fast FWD cars but I also like classic cars. I own a 1962 Oldsmobile Jetfire. This car sports a 215 cu.in. all aluminum V-8 that was the predecessor of the modern Range Rover V-8. The Jetfire has a 10.25:1 compression ratio and was turbocharged with a draw through single barrel side draft carburetor. How did Olds get away with turboing a high compression engine? A tank pressurized from the intake manifold contained a 50/50 mix of water and alcohol. If the water injection tank got too low then a second butterfly would drop down in the carb throat and joke the engine so much that you couldn't build any boost, but this prevented engine meltdown. Max boost was 5 psi by the way. This was enough for 215 crank HP from 215 cu. in. One HP per cubic inch from a factory engine was not frequently achieved back then, nor is it now.
Putting a turbo on a high compression engine is very possible, even with something as low tech as a carburetor.
