ok...WHY total seal rings? use the rings that come with the CP's
also..the 50# injectors will only get you to 350 hp unless you go to a JWT 4-bar program...but i hate JWT so i never reccomend that. especially if you are goign to want to run 25 psi boost becasue that means 85 psi fuel pressures!! WAY TO HIGH...you'll kill the walbro in no time like that.
