hey thanx alot for the info...if i were to get the OS GSR pistons, i was once told that it requires removal of too much wall, making it unstable? anyway i plan on doin some head work down the line, but for now i wanna get it ready for the boost and break in...boost wont come for a lil while, but looking ahead...
p.s anyone have any thoughts on the ring situation? (file fitted that is)
