we finally have a couple of vendors that make turbos for our car. AAI makes one for the RS/GS. I think johnnyb is selling one from his company, and i think XI Racing is currently testing one. RIPP MODS has built a supercharger for the GT/GTS. many members at
www.eclipseforums.org and
www.club3g.com have this supercharger on their cars. they have gotten good reviews with this supercharger. also, some people have done custom turbos on their cars. i think rulez has that kind of turbo on his car. he usually posts on this site too. it would all depend on the amount of funds you have. i myself would go with the supercharger, just b/c its been proven by many people.
