As for the hotside I took it off to port match my FP exhaust manifold and these iphone pics make it look bad but its actually really nice and really smooth inside.
That's actually really nice looking and insane considering that's all $900.
If I were you I'd consider porting the j pipe or make a new larger one. My biggest pet peeve with the stock drop in stuff is how small the outlet is. It's honestly amazing that people can shove up to 700hp through that small hole. Can you measure the ID of that?
I'm curious to see how accurate those wastegate springs are though.
Oh, also it doesn't look like there's a restrictor built into the oil feed port so be sure to use one in the line or buy a feed fitting that has changeable restrictors.

oh yeah the j pipe is getting ported for sure at the very least, and i purchased a new oem j pipe gasket that I will modify as well. ideally i would like to make a custom j pipe but I got no welder currently. As for the restrictor it actually does have one, you have to see it in person because i can’t take a picture of it due to the angle. The restrictor is part of what keeps the ball bearing cartridge pinned. I got a lot I need to do before I throw the turbo in, drilling and tapping the valve cover for 3 10-AN ports is one of them, cause I don’t want this thing puking oil. And yeah for $998 you do seem to get a lot, especially if this performs decent!
Unfortunately the jpipe does not have much material to work with so that I could at least somewhat port match it. Ill have a friend try and put some more material behind the flange and on the pipe itself and try to port match it a bit. Look how much smaller it is than the gasket:
Consider making a custom J pipe, with the outlet that large you're just bottlenecking it by using the stock J pipe anyway. I've designed a stock flange with a 2" discharge for when I make my new charge piping next year, it uses an oring too so no need for a gasket.
If there's interest from people for a large outlet pipe on drop in turbos I could probably get the ball rolling on getting some made
