Closed Deck EJ20 Base Shortblock With Forged Internals FA20DIT WRX Shortblocks The thick discs have betterThis 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
