Product Description
This RCM 2.1-litre EJ20 stroker kit combines the following components:
- Subaru EJ25 heat-treated crankshaft, manufactured by FHI Japan and induction hardened for wear resistance.
- RCM/Omega forged piston set. The pistons are forged and CNC-machined by Omega, then individually weighed and batched to within 0.5g, keeping a four-piston set within a 2.0g tolerance.
- Manley H-beam connecting rod set, finished to the same tolerances as Manley’s higher-priced Sportsmaster and Pro Series rods.
- ACL Race Series engine bearings, featuring a high-strength overlay plate, hardened steel backs on rod bearings, increased crush for retention, no flash plating on the bearing back for improved heat transfer, increased eccentricity to compensate for bore distortion at high rpm, 3/4-grooved main bearings, tight wall tolerances and enlarged ID chamfers.
Piston sizes available: 92.00mm standard, 92.25mm, 92.50mm and 93.00mm oversize — select from the options above.
