Standard services include identifying the required level of tune, from a stock road application to full race spec, and delivering an engine tailored to specific class rules, including appendix K.
JSM can provide either new or reworked full race engines and use only the highest quality components made to its own specifications by top manufacturers including Arrow, ARP, Kent, Cams, Omega and Weber. Stock engine rebuilds are also available, again, supplied from new or rebuilt from a donor unit as 'standard' or in 'fast road' to race specification.
