Subaru OEM EJ255 Short Block Engine 10103AC880 - Crawford Performance

New OEM RA Shortblock W- Forged CP Hybrid Pistons 99.5 – Outfront Motorsports

The IAG 550 Short Block is designed for modified EJ25 Subarus that need a stronger short block to support increased cylinder pressures created by additional boost pressure. The IAG 550 short block features IAG Spec H-Beam forged connecting rods. The upgraded connecting rods and race bearings are able to support additional engine load produced by larger turbochargers or increased boost which the OEM STI rods found in the Stock short blocks cannot support reliably.

IAG offers our Version 2 Oil Pickup, Baffle and Windage Tray as a complete package and even better at a reduced price instead of buying the items separately. The IAG Performance V2 WRX / STI oil pickup replaces the OEM EJ25 oil pickup which is prone to failure. It's a well-known fact that the OEM oil pickups often crack and fail which in most cases destroys your motor from lack of oil pressure. The original IAG Performance pickup design has been improved in this all-new stainless steel version.
