RCM 2.1ltr forged stroker engine with 14mm Head Stud Conversion.  

We have a range of short block assemblies ready to ship as you order.  Each assembly starts with brand new block halves direct from Subaru, which have our 14mm RCM Head Stud Conversion undertaken on them.  They are then thoroughly cleaned, inspected and measured, before being honed to perfectly suit the appropriate pistons.  All components are individually selected and checked to ensure they are perfectly matched.  The short engine assembly is then meticulously hand built by our own expert technicians.  Finally, each assembly is given an RCM identification badge prior to dispatch.

Studs shown for illustration purposes only, will need to be purchased separately.
