IAG 950 Closed Deck Long Block Engine w/ IAG 950 Heads for 02-14 WRX, 04-21 STI, 04-13 FXT, 05-09 LGT

This is the long block for EJ builds that are headed into serious race territory. The 950 short block and CNC ported race heads make it a much better match for cars that need more airflow, more sealing, and more overall engine headroom.

• Power rating: 950 BHP
• Package: Closed deck EJ long block with IAG 950 race heads
• Head package: CNC ported race heads with larger valves, upgraded guides, springs, retainers, and cams
• Best use: High-horsepower drag, time attack, and competition EJ builds

Why you'd choose it: Choose this when you want a ready-to-go long block that makes sense for real race power instead of a milder street combo.

Fitment: 2002-14 WRX, 2004-21 STI, 2004-13 Forester XT, 2005-09 Legacy GT
