going from NA to boost very soon and i have oem over sized pistons in it right now. i searched but didnt find anything on people honing out there sleeves to 82mm. power goal would be 450whp in a b series on the sleeves.

TIA

 

you could go 81.5.. isnt OEM OS 81.25

yea oem OS is 81.25. thanks for the quick reply. i didnt think of going 81.5

 

Your not going to safely make 450 on oem pistons anyway.Sell your short block and start over.A sleeved 82mm block is no problem w/boost.

He wants to DITCH the OEM pistons and rebore the engine to 82mm and i dont know of any OEM pistons that are 82mm. so i imagine he is going with Forged internals.

 

bore to 81.5 and use aftermarket forged pistons/rods of course. def should be safe for 450whp

 

yeah. ditching the oem internals and going with aftermarkets. sleeving my block is out of the question since ill rather spend 1000 on pistons and rods then sleeving the block. 81.5 is the path im going to take with forged internals.
