I've got one of Mike's kits on my 782D. It's a great kit, very complete and Mike is good to deal with. The 782D will make about 6 pounds of boost pulling a loaded cart up the shallow grade on my property. There are no traces of oil in the air tubing. My drain line is routed similar to yours but by using careful routing I got it to slope downhill all the way to the fuel pump block-off plate where it drains into the sump. I would check the waste gate carefully to make sure it seals against the body of the turbo. The kit uses a spring to keep the "door" closed instead of the actuator that would be there in the normal application. Most likely there is something under the door allowing no boost. I'm sure Mike and the rest of us can help you thru this. The Kubotas are a great little engine and a lot of fun at the shows when they have a turbo on them.
