Ordering and build notes

Supplier states approximately 12–14 weeks when the kit is not in stock. Final compression, piston-to-wall clearance, bearing clearance and balancing must be set for the actual engine build.

BBT fitment note

Confirm the exact engine specification, machining clearances and supporting components before assembly. Professional engine measurement and assembly are recommended.
