IAG 550 2.5L Subaru Short Block for WRX, STI, Legacy GT, Forester XT - 550 BHP

This is the entry point into a real forged EJ short block when the stock bottom end is no longer the right foundation. It is built around new case halves with stronger rods, forged pistons, and race bearings so it can handle real boost and real use.

• Power rating: 550 BHP
• Core setup: 2.5L EJ short block
• Bottom end: Forged pistons, H-beam rods, race bearings
• Best use: Street cars and moderate power builds that still need reliability

Why you'd choose it: This is the one to choose when you want a solid street and track short block without stepping all the way into the more race-focused closed deck options.

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

Selectable options: Choose the seal kit, oil pickup or baffle setup, and Stage 1 or Stage 2 EJ25 11mm oil pump from the product options.
