FS: Almost new Borg Warner EFR-6258 turbo

I have a Borg Warner EFR-6258 turbo, single scroll, internally recirculated, set up for external wastegate, with V band flanges in and out.
This turbo is only two years old, less than 1000 miles on it (autocross and hillclimbs only), but due to now rebuilding the motor to larger displacement it will be too small for me to keep using.
It is extremely fast spooling, you dont need a blow off or recirc valve because its built into the casting and recirculated air only has to travel about a half inch, reducing lag. This does not have a built in wastegate.
It also comes with a built in, unused, Electronic Boost Control Solenoid.
Internal oil flow restrictor.
This is the smallest of the EFR turbos, and is good up to 420hp. Common on Miatas, etc.
I was running a motor with horrible compression in two cylinders and was pushing mid 300s on 16psi.
Looking for $900 plus shipping

Image upload doesn't work on mobile, so I'll have to add them in a bit.

I made 330whp in the beginning of 2017, on horrible compression. By the end of the year, my compression was to the point that I couldn't hit rev limit (spark cut) without fouling plugs instantaneously. Here were my compression numbers - I was so discouraged by wet to dry numbers that I stopped and knew I needed a rebuild... haha. The turbo has tremendous potential!

Yes - V band in and out, you can weld one to the crossover pipe. And downpipe.
Need an adapter plate for the oil drain to mount on the pedestal, and adapt for oil feed.
Is by no means direct fit. But it's a great turbo
