So I have a 2001 2.5 rs.. I also posted Something about a CAI for the rs and got a lot of help so I figured I'd try in this forum again... Okay so the rs just hit 190,000 and since my dad is an auto technician and owns a auto business we decided to redo the whole engine but I really want to turbo it without doing a wrx or sti swap.. Was thinking high compression pistons to handle it? I was thinking only like 5 to 10 pounds of boost anyway... But worth it? Share your ideas!
