Seeme like dry sump is the only real solution, but that it also involves a fair bit of custom work, which Is fine but time is not on my side...
I've seen the setup on the SZ site, looks fantastic but has the price to match. I like how the pump is built in to resolve mounting issues and reduce the amount of plumbing. Is the first stage reserved for turbo oil drains? Have head drains also been considered?
Finally where are you planning to mount the tank and what capacity are you going with?
