CREST CNC Subaru EJ22 Billet Block

CREST CNC has rethought the Subaru EJ block casting. The billet block is designed to remove the problems the standard block faces in high-power applications, including improved piston-to-bore sealing. With the right build and supporting modifications, these blocks are designed and tested to support applications up to 1000hp.

Each billet block is CNC machined from solid 6061-T6 aerospace-grade aluminium and features:

• Darton ductile sleeves, fully supported to eliminate sleeve drop
• ARP block case bolt kit
• 4-bolt main tunnel system
• 8 block main dowels (compared to 2 on the OEM block)
• Clearanced for stroker applications
• Precision tunnel boring and hone alignment
• Precision deck finishing
• 14mm head stud threads
• 16.5mm dowels

Available in raw aluminium, hard gold anodised or hard blue anodised finish.
