I'm all for the bottom mount turbo locations as they place that hot turbo away from the engine but there's just one thing that turns me off most... having to run a scavenging pump! Just another thing added to the list of potential fail points.
As said earlier, there really aren't any compromises here which is a bummer
I still think Ptuning has the best kit but be prepared to run an external oil pump if you're okay with that. AVO, same thing.
