Description

THE PROBLEM SOLVER

The IAG Stage 2.5 Short Block is designed to solve the majority of common problems which plague modified EJ20 engines, especially at higher horsepower levels. The IAG Stage 2.5 short block builds off our Stage 2 Tuff block’s strengths by adding our proprietary closed deck system. This system strengthens and supports the cylinder walls to prevent cracks which can occur with increased cylinder pressures. (This is the most common issue when increasing horsepower.) The Stage 2.5 EJ20 Short Block also features 92.5mm JE Forged Pistons and IAG Spec H beam connecting rods, along with ACL or King Race bearings. These components also significantly strengthen the common failure points such as cracked ring lands and spun bearings. These blocks are intended to be used with 2.0l EJ20 cylinder heads.

Stage 2.5 Closed Deck EJ20 Includes:

  • Case Halves –Converted to Closed Deck using brand new Subaru OEM case halves, bored and honed to 92.5mm.
  • Pistons –IAG-Spec JE FSR 92.5mm 2618 Forged Pistons, Ring Set, .210″ 9310 Steel Wrist Pins, Clips, (Perfect Skirt Coating and Offset Wrist Pins)
