Pin drive oil pump for 1275cc engines, as originaly used in the Cooper S. CNC machined from alloy billets with sintered internals assembled to very exacting standards. These close tolerance pumps produce consistently high oil pressure even at high RPM (10L/min at 1000RPM). So finely engineered that there is less oil drag on the pump giving potential for higher BHP.
Please note 'S' blocks will need drilling and tapping to fit this pump as not all the holes in the pump will line up correctly. You must drill and tap the block so that all four holes in the pump are used.
