IAG 800 FA20 Subaru Closed Deck Short Block for 2013-20 BRZ, FR-S, and GT86 (12.5:1 Compression Ratio) - 800 BHP

This is the closed deck FA20 short block for BRZ and FT86 builds that still want standard compression. It keeps the stronger block and sealing package, but it is a better match for lower-boost or sharper-response combinations.

• Power rating: 800 BHP
• Compression ratio: 12.5:1 standard compression
• Block style: Closed deck with O-ringed deck and 1/2-inch head stud machining
• Best use: Lower-boost or responsive BRZ, FR-S, and 86 builds that still need serious strength

Why you'd choose it: Choose this when you want closed deck strength but do not want to step down to the lower-compression version.

Fitment: 2013-20 BRZ, FR-S, GT86
