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.

This engine consists of the following parts:

  • Seasoned EJ257 case halves
  • Rated to 775 BHP as configured
  • Assembled with 2mm Longer rods for a better rod to stroke ratio.
  • V3 Closed Deck Process
  • JE FSR Pistons
  • Outfront Motorsports +2mm Longer Tuff Connecting Rods W/ ARP 2000 Bolts
  • King Performance Bearings
  • New OEM Subaru Nitride Treated 2017+ STI Crankshaft
  • Rear Covers, Rear Seal, and Pin Plugs Included!!!

No Core required!!
