In Green Bay there is a supercharged 928 with a 6.1 liter 928 stroker motor running a blower that was pushing 22psi (before the stroker install - engine is not ready for that boost yet). Everything on the car is 100% stock except for the gear vendor reduction unit (it's an auto).
Tim Murphy (of murf928.com) ran for years with stock everything on his S4 with well over 500rwhp. It all depends on what you plan on doing with the car. Low - moderate boost on a stock 944 will be fine, assuming all the stock components are in good shape.

Geo, that would make you quite a popular guy if you could find a place that would be able to coat pistons for compatibility with alusil bores. I think some others have tried this before but it always ends up being an issue with economies of scale - since there isn't much demand, production costs don't get offset by a large production run for the piston manufacturer and as a result the price is still high - not much better than the Mahle ones.
I agree that someone should be able to do it though. . . It ain't rocket science - this is metallurgy technology that's at LEAST 30 years old.
The thing that concerns me about boosting the n/a block is not the compression ratio - as has been rightly said, there are ricer guys boosting engines with native compression ratios of 10:1 and even higher - and they're boosting using 25, 30 even 35 psi sometimes! It's all about the tuning.

Swain helped me with my turbo G20 project that I did an article on for Sport Compact Car. They also did all the coatings for the NA SR20DE I built for my Sentra SE-R. On top of that, I was the one who put Mike Kojima of Sport Compact Car onto them which has been good for their business. I think I might be able to talk him into at least exploring the idea. I'm going to try when I'm ready. Or, if someone not only wants to try right now, but is ready to put up cash for pistons and coatings, I'd be happy to talk with them now. But someone needs to be ready to spend cash. I won't waste their time with what ifs.

One huge difference.. I see alot of folks comparing 4 valve results to a 2 valve. The chamber is far inferior IMO, especially for boost.
If I ruled the world...
16V head, large variable turbo
