I have a d16y7 with y8 top and it was just completely rebuilt from the bottom up. The cyclinders have been bored .020 over and what i want to know can these aftermarket oem pistons handle good boost and if so what would be the max with good tuning. next has anyone heard or seen these vitara pistons in action and where can i get some besides ebay?

 

get some 25 oversized...advance auto..autozone...etc...

 

do what, get some 25 over sized, and what about autozone?
