I believe the 3.2 can be made to work with forced induction easer than the sc because of the fuel systems for sure, but I feel other than the issue of smog in California what issues they're are with turbo charging a 3.2 revolves around the compression ratio. The 930 is built for pressure, the 3.2 is not. The case is basically the same for both cars and there are some other small details that change between the two types but mostly were talking about pistons and the compression. There is a lot if power in the 3.2 engine to come out for sure but its more of a tight rope walk than a 930 because of the safety margin built into the 930. Crap, the factory went even further by changing the cooling effect of the cylinders by removing some fin length on the 930. There's a lot going on in the design there.
Air cooled porsche engines don't have high compression by today's standards and there is a reason for that. The 3.6 got twin ignition and that's for the ability to go higher compression. Even then it's still not as high as a water pumper. Modern turbo cars from other companies even porsche have higher compression than our air cooled cars. So, the idea of pressurizing a 3.2 needs to be taken more seriously wether it's in any body 911. Be it targa, cab or whatever crazy concoction some dude desires. The point that needs to be that there is care if the internals are intact. No boost knobs available, no high boost without race gas or e85. Or lower the compression.
That's it.
O-and there better be an Intercooler on it.
Turbo powa!
1977 911s. it's cool
