the truth of all this is its not all about internals yea ur friend who has been mashing the #$%^ out of is 300 hp y8 turbo is lucky thats it u shouldnt run more then 7-8 pounds and have no problems but that block has potential for much more on all stock internals with a resleeve. that should be the first thing u ever do to that motor if ur gunna seriously be looking to make over 200hp
