Officially a retractable 182 is an R182. The turbo model is the TR182.
It
is common to see 182RG and T182RG but to Cessna these are wrong.
Doesn't surprise me. I just wanted to alert John that there are people
like
me going around using unofficial terms. 
For FAA/ATC purposes, it's designator is C82R.
