Dude don't go there............there is no reason why you can't cure those problems without dry sump. It's done for power, not reliability.
I've dry sumped cars before, you go there when you pretty much give up on the car being a street car. Simply way too much complication for the smaller amount of hp you'll get from a 4 cylinder if not supercharged.
Dry sump not well thought out is often a source of many more troubles and many of those result in motor blowups.
