Dry sump modifications

[Zoltarc]

Aside from the obvious modifications needed to the sump are there any other modifications needed to convert an RB26 to a dry sump setup.

Remove crank driven oil pump and replace with a blanking plate. I can only assume the primary feed can then be directed straight to where the oil filter normally sits via an adapter. Or does the blanking plate need to have a feed plug tapped into it?

Do any pump holes inside the block or bearing caps need to plugged with the RB26?

Is it necessary to scavenge the cam valleys? I don't believe so myself.

If the oil feed to the head is restricted to stop pooling and the return paths enlarged this should negate the need to scavenge the head.
