Description
This Block Is Our Closed Deck EJ257 With Forged Internals. This shortblock is for 550 WHP or less and 30 PSI of boost.This closed deck block design has been proven to withstand extreme boost levels resulting in high cylinder pressures without the worry of cracking a sleeve. The billet material that reinforces the combustion area has been further optimized with our V3 closed deck block in the known problem areas making it a far superior product to any sleeved block. With a closed deck block the stock sleeves are still in place eliminating all risk of dropping sleeves and pushing coolant that you have with a sleeved block.

Seasoned EJ257 case halves
V3 Closed Deck Process
Forged Pistons (Default is CP but you can choose any shelf JE, Manley, or CP piston)

New OEM Subaru Heat Treated Crankshaft
