the internal integrity of your engine can have surprisingly litte bearing upon an engine's performance, especially regards a turbo engine where you have large excesses of air pumping capability.
I'm not talking about engine longevity here, just speaking strictly to the performance aspects, that's all.
My point is, if your engine specs ok (compression check, oil pressure?), then, for your goal, you may not even need a rebuild! Or, maybe not a rebuild as comprehensive as Dman, where a cam lobe went south and did further damage.
Off topic: My take on outsourcing engine work is the same as for any other business: You loose oversight, accountability and control of the product -do you work as hard on your neighbors project as you do on your own?
And, of course, ya gotta put up the labor bucks.
So, do your "homework", as they say. Hopefully, you get what you want.
