A few years ago, I needed to rebuild the engine in my 1980 SC due to broken head studs and some other issues. After a lot of reading and picking brains, I finally decided to do a 3.3SS with Carrera twin plug heads, 964 cams and Electromotive XDi ignition. I replaced the air box with an early, large port box and basically replumbed it like a 73.5. The Mahle pistons were supposed to be 10.1:1 compression but wound up being about 10.8:1 due to previous machining on the heads. The end result is an engine that starts easily, runs well on pump premium and revs like crazy. Someday I might pull the CIS off and replace it with a set of PMOs but I wanted to see what the CIS would do on a built engine. By shopping around and getting good pricing on most of the parts I wound up with about $10-$12K in this engine. I performed all the labor so that probably saved around $10K or so. It can be done!
