Just documenting a few things that might help others. The install was on a 2017 Police Interceptor sedan.
1) The OEM-spec CHRA's from CR Performance are made in the UK by Melett and they claim to use their own parts. They come with the needed o-ring for the turbine housing. Avoiding Chinese junk is possible...a big issue for me.
2) If you purchase CR's upgraded turbines, they simply replace and rebalance the turbine that came from Melett. CR does this at their facility in Canada. I could not find any performance data so I opted for OEM-style.
3) CR does not collect US sales tax. I have no idea if/how taxes would be collected.
4) I purchased the gasket kit from CR and while it worked, it was not the best. The crush washers had about 50% less sealing surface over the OEM ones and they were not coupled together like the OEM ones. It was a huge challenge to install them on the cooling lines on the rear turbo. I would definitely look for an OEM kit next time.
5) You can easily remove the rear turbo without removing the axle shaft. I removed the two bolts holding the steering rack allowing it to move back about 2 inches. Rotate the turbo vertically so the downpipe surface is facing down towards the opening. The biggest issue is making sure the cooling lines are pushed back well away from the turbo to avoid entanglement.
6) Remove the rear engine lift bracket to make life easier. Leave it off for weight reduction
7) If you have trouble using the quick release tool on the rear turbo oil line, just unscrew the entire quick release housing from the head. Then remove the line on the bench and reinstall the housing to the head. I used Loctite 592 sealer.
8) Do not buy new oil lines to replace the oil screens. The oil screen is inside the hole where the banjo bolts goes (on the turbo). They are brass and slide out in one direction only. Blast them with brake clean and reinstall. Both of mine had some blockage so don't skip this step.
9) Our turbos have clocking pins on each housing so don't worry about getting the clocking right.
10) There are left and right versions of the CHRA's.
11) If your old turbos were spraying oil throughout your charge pipes and intercooler, clean them. An oily surface does not transfer heat as well as a clean surface.
12) Have a beer to celebrate no leaks.
