just because your friends car was "ok" doesn't mean anything. did he scan it? doubt it. pullies are not the 1st mods. with my mods and a 3.5 i knock. so a close to bone stock and a 3.4 will eventually grenade. go ahead and list your car on "parts for sale"....not trying to be an a$$ but read the stickies, their here to help u new people!
