USTCC is a late model series. I needed to move to at least an E46 chassis. I decided to go to an E9X instead and make sure I can race this car for a long time to come.
The series is a power to weight ratio, so you can adjust by adding power if you weight more. The newer cars are also allowed to run 275 tires while the old cars are only allowed 245. The last reason; 3 models old and you get a 150 lbs weight penalty as well.
No mods to the firewall, sub-frame, or rear drive shaft needed. Only motor mounts, custom BTM mounts.

The more I think about it, the more I wonder why the chassis swap at all? Your E36 is smaller and lighter, no?
