oil squirters

[effvee]

Hi, I'm looking for an alternative way to supply oil to the interior (back side) of the pistons. Currently my engine has been moded for the 911 oil squirters.

Although I have seen external oil supply, along the side of the case, that's is what I'm looking for.

I just don't see how the squirters,which are aimed at some part of the interior of the back side of the piston;will cover the area well enough.
