my engine blew up on my 05 lgt, the turbo took a dump first, i replaced it with a vf52, now something in the bottom end went bad. i am thinking of rebuilding it with tight fitting pistons like the woosners? i have a fairly mild build with 280awhp, and 300 tq but i might turn the whick up to 300whp since i have to rebuild anyway. are stockers good enough for a 300whp dd?
