if your spending the money on putting up rated pistons in what is essentialy a new block id say spend the extra few dollars and get a matched set of pistons, incedently why?

and nxttruck, no real point breaking the motor in as when he changes the pistons he will have to run it in again as new to seat the new rings

i was thinking since the block is still so new, i can drop the pistons in and not have to worry about sealing issues..am I in the right frame of mind? if not guide me, no use in spending $2300 for new block when i can spend $600 for pistons

All of the blocks have inconsistancies in the bores. The cylinders have "A" and "B" sleeves which are something like 2/10 - 3/10 of a thousandth different. I would suggest honing the block the block and getting a final bore. Then get that bore and order some pistons. I know most people dont like JE but they have a really bad ass new design for the EJ257 that they have availble that no one knows about. I have seen them with my own eyes.

Wiseco's? Just about any set of pistons will drop in be fine and give you no trouble. Any set of forged pistons will probably outlive the block, or at least the rods.

Actually, the "allowed" tolerance between the A and B sleeves is a full thou. On a recent new block we just built, it was more.

Boxer, at the very least measure to double-check and touch re-hone for better new ring seating. You can do this without splitting the case if you have someone who knows what they're doing.
