K20c Oil Pan porting

Description

This modification will easily be the most significant increase in oil flow you can add to the k20c engine. A ported oil pump helps but not as much as this one modification. It has been tested to 9000 rpm and shows no pressure drop unlike running just a ported oil pump. This modification is a fantastic for anyone wanting more than 7400 rpm and a must for anyone revving to 8000 rpm or more. Stock  pan configuration shows a 10-14 psi drop beyond 7400 in many applications.

****This will not solve an engine that the bearing clearances were done improperly. ****
