"S" 2 bolt fitting, long pin pump. Almost all pumps available today have the same design capacity. The problem is the lack of precise manufacturing. Most factories in their quest for production volume have sacrificed precision. These special pumps are 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 RPMs (10 Litre/min at 1000RPM).

So finely engineered that there is less oil drag on the pump giving potential for higher BHP. Alway check the fixing bolt length because if they are just slightly too long the pump will never seal against the gasket and block causing oil drain down.



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.
