IAG 800 FA20 DIT Subaru Closed Deck Short Block for 2015-21 WRX - 800 BHP

This is the stronger closed deck FA20F for WRX builds that are leaning harder on boost and cylinder pressure. It adds the extra support and sealing strategy that makes more sense once power keeps climbing.

• Power rating: 800 BHP
• Block style: Closed deck FA20 DIT
• Sealing support: Closed deck support and stronger head gasket clamping path
• Best use: Higher boost WRX builds that need more than a basic forged short block

Why you'd choose it: Choose this when your WRX build is headed into the range where closed deck support starts making sense.
