VG turbo improvements?

[dhirocz]

I'm fortunate that not only does my truck appear to have had a recent turbo installed before I bought it, but I have another low mile turbo/actuator at the house.

I have no reason to doubt the stock turbo's capability. But I'm all about improving reliability.

Would it hurt running a small oil cooler in line before it feeds the turbo?

Any thoughts on having my turbo jet hot coated inside and out to help control heat and improve efficiency? What about a turbo sock?

I used to port cylinder heads as a hobby. Anyone clean up the casting internally with a die grinder? I was also curious if anyone has tried cleaning up( not porting) the intake to make it harder for soot to build up?

Anyone using an air filter sock over their primary filter?

and yes, I'll be putting an air shutoff inline with my turbo. Just in case.
