Our Subaru Stage 3 Shortblock is for those that want to push the stock sleeves to their limit. We utilize many of the same components as the lower blocks but build with the Carrillo Pro-SA Rods with the WMC bolts. These are some of the most tried and tested rods in the industry and offer superior finish quality that nets real peace of mind.
While the components used are capable of handling far more, we really insist on capping this block at 500-550hp as the cylinder walls will be your weak point.
The Mazworx Stage 3 EJ257 is built with the following components:
- NEW OEM EJ257 Block
- NEW OEM Forged EJ257 Crankshaft
- CP 99.5mm Forged Pistons
- Carrillo Pro-SA Connecting Rods (WMC Bolts)
- ACL Race Rod and Main Bearings
- ARP Case Bolts
Each block is carefully inspected, cleaned, machined and assembled, in-house.
