umm...you can bore and hone the stock sleeve a max of .25 over to 87.25mm
anything above that and you have to resleeve the motor. Sleeves usually will be installed like 30 under 87mm, then the machine shop bores them out to whatever piston size you chose. Max bore on an H series iron sleeve (aftermarket) is 89.5mm, 90 is pushing it.
I am bored to 89mm.

cause they weren't 87mm....
did not not measure the pistons and the block? to see?
And why the hell would you be trying to put forged pistons in a stock block?

if you kept compression the same....boring increases hp and torque fairly proportionally...but usually people up the compression at the same time so it's not so cut and dry
