Choosing a new turbo

Choosing a new turbo
I have a divided DBB gen 2 6466 that is burning oil and I am leaning towards a new Borg S366. I've had trouble with every precision I've had so far. My current setup is far over built for what I want power wise.
Inline pro sleeved 2.4 stroker
9:1 compression
Dual full blown 340 pumps
Full blown twinscroll sidewinder
The kicker is I am only staying on pump fuel now. My current turbine housing is divided and it says 132 AR on it. I want the Borg S366 with the divided 1.10AR housing. How will this perform compared to my turbo now?

Edit: Never mind, I see you have a low compression motor.

The S366 was probably the laggiest turbo I've ever felt with a .96 AR twinscroll I believe. On one car with an AFI manifold it didn't really make boost until 5800rpm and was still pretty meh. Made 722hp @ 33psi on a stock block.
How is your precision throwing oil so quickly? The Gen 2's have built in oil restrictors

Where is your drain for the turbo going to? If the oil pan on the passenger side, that's probably your problem. We have been over this numerous times over the years. The oil drain needs to be either in the girdle above the oil pan, in the front drivers side upper area of the oil pan or in the front cover so not to get backup and end up causing the turbo harm.

I would also highly consider the Garrett GTW3884R and it comes in 3 different inducer diameters and ball bearing. It also has 3 different A/R turbine housings with the T4 divided flange. It's an 800-850whp turbo.
