hi. i own a 2004 rs225 that came to me a couple of years ago , i'm from spain and live in spain, my unit was originally from france. its been a long time from that,. actually im trying to forge my engine, cause the one its on it its a little bit smoky. dont want a real extreme car because its my daily , but as long as i cant find pistons i believe the only way is making it forged. forgive my english.... thanks!!
