This Block Is Our Closed Deck EJ20 With Forged Internals. This short block is for 700 BHP.

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 EJ205 case halves
  • V3 Closed Deck Process
  • Forged Pistons (Default is CP but you can choose any shelf JE or Manley)
  • Outfront Motorsports H Beam Rods
  • King Performance Bearings
  • New OEM Subaru EJ20 75mm Stroke Crankshaft
  • OEM Case Bolts
  • Rear Covers, Rear Seal, and Pin Plugs Included!!!
  • DEFAULT: 8.5:1 Custom CP Pistons UNLESS you select a different Block Configuration in the pulldown.
    • 8.5:1 JE Pistons
    • 9.5:1 JE Pistons
