If you could some how get a hold of a pair of Aerocharger turbos from their short run Focus turbo kit, you could use those in a twin setup. They use a self contained oil reseviour and are mountable virtually in any position. Each is only good to 220whp on the Focus, but in pairs on the V6 you should do around 300whp.
The biggest problem is Aerocharger no longer in business for automotive applications so you'd have to find used units and they almost always will need a rebuild because the variable vanes get gunked up causing overboosting and the turbo breaks past 12psi. However, some people have just added stock external wastegates and that fixed the overboosting.
But they are hard to get just one these days, nevermind two.
