Hey Monty;
Not sure what you mean below, but our situation is, our Garrett Turbo is hanging too close to the bottom of the pan, in order for it to fit in the cowling of the Legacy.  Our solution is to collect the oil from the turbo, and Tracy's redrive into a small tank, and then hang a special scavenging pump to get the oil back in the system under pressure.  The pump we're using has been tested under race conditions, and is very reliable, as well as simple.  This means a combination of dry sump and the stock oil system, it's pretty inexpensive, and solves a lot of problems for me.

I recall a discussion a while ago about a remote oil tank. I am as usual trying to put 10lbs of poo in a 5lb sack. I don't want to use a dry sump for weight and complexity reasons. How far below the oil pump inlet flange do you  guys think I could locate the oil level before I start to have problems with foaming.
 
Ed, how long is the pickup tube for your tank and how far is the oil level below your pump inlet?
 
Thanks,
 
Monty
