This is a Closed Deck (Semi Closed) EJ257 +2mm Long Rod Engine With Forged Internals.

This is for 550 WHP or less and under 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 the 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.

This engine consists of the following parts:
  • Seasoned EJ257 case halves
  • V3 Closed Deck Process
  • Forged CP 8.2:1 Pistons
  • Outfront Motorsports H Beam Rods
  • King Performance Bearings
  • New OEM Subaru Heat Treated Crankshaft
  • Honed with torque plates

No Core required!!
