I'm currently talking to a local STS dealer here in Alabama about the possibilities of an STS being fabricated. There also a company called Phamspeed that makes some great front mount set ups. The only problem is they have never messed with Crossfires. I will contact a friend that works at Procharger and see what type of R&D they have done if any. A centrifugal style would be the most cost effective and easiest bolt on application. A front mount turbo would be a LARGE project to under take and would be far from easy to install. Still the bottom line is dollar per HP rate. Paying $95 per HP is not worth it (my .02 cents). Paying like $55 - 65 would be.
