i was doing legacy setup up but now wrx setup. but it reguires some legacy picecs so it takes awhile to find... its risky for me b/c if my shit was to blow up i dont have the extra money to my a new motor . some people do . they have all these ludespeed and avo kits for 4000$ which is a ridiclous price. to be honet with everyone , with any turbo kit for a rs , unless you have a fully rebuilt motor just about , its going to be a huge risk to turbo it.
