How are you guys with Subaru turbo engines handling your turbo oil scavenge?
I'm actually swapping into a 912, and I don't have any room for a top mount turbo, so I have to go with a bottom mount turbo. That means I'll have to scavenge it somehow. The 914 too is pretty tight engine space wise, you guys also have to run a bottom mount turbo right? A couple options are one of those electric scavenge pumps, but I hear they're crazy noisy and loud. Another option is somehow machining one of the heads and using a cam mounted scavenge pump. Or what about using a power steering pump as a scavenge pump? |

When we were building the turbo systems for the (then new) 928's, same low mounted turbo oil return issues. Problem solved by using the Weldon 12v (FAA grade) oil pump. Has #12 a/n fittings, and high duty rating...just don't run it dry so run a separate switch, other than the "On" from keyed ign. You can even pump the oil straight uphill to the return area you choose.They are not cheap and have a super good track record...unlike the Ebay pumps. Weldon ships from their factory in Ohio.
