[Mg-t] Pressurized cooling system?

[JohnD]

I've seen write-ups on fitting a coolant recovery system to the pre-TF T car
system.
Makes me wonder if anyone has converted a TD to a pressurized system?  Maybe
sealing the radiator cap with with a rubber gasket and tightening it up and
then running a tank off the overflow with a low pressure cap?
Thoughts?
Thanks in advance.
