I am converting a 150 2.0L to a 200hp 2.4L. <br />I know that I have to enlarge the orifice in the oil pump itself. I have carefully removed it (the cover has two phillips screws, Oring, spring, then the brass pump orifice can be pulled out.<br />This rotates, and has hole in the side of it which needs to be enlarged to increase the oil pump capacity to support the 2.4L power head.<br />Can somebody please tell me the diameter which I should drill this out to?<br />Peter Roy<br />Toronto<br />peter@broy.com
