What engine mods should I get for the hahn stage 2 kit? I dont want my engine to blow up, and I know nothing about psi or boost control or anything. I believe I may need to get the weiso or JE forged piston and those billet connector rod things? My 97 rs is all stock except for body kit, rear/front strut bars, and a pace setter catback exhaust. What mods will I need to safley run my engine? thnx guys!
