the whole set up is quite easy....1st you need to source a scavange pump then the rest just make up yourself...the sump plate can be made up out of billet alloy plate and machined up....you can also releive the head of oil by tapping into the head itself depends on the paticular engine in question...this helps stop the oil raining down through the engine...The benefits is an excellent supply of oil to the engine at all times,releif of pressures inside the engine and the less drag on the crank as less oil will be flinging around in there....heres a custom built engine with a dry sump where the plate has been milled up from billet....
