You do realize that with this set up, you are taking the oil, running it to a separate filter, then one line goes to the turbo, and one to the engine. On the factor set up, the first port after the filter is the turbo feed and gauge/dummy light. The turbo gets the filtered oil first. If you have a major engine failure, the filter will still clog, and the bypass will still let the crap through, and send it to the turbo. The only set up that does anything different is the one that filters the turbo feed only. If I am wrong, someone correct me, this has been my train of thought for years.
