Default Improving/upgrading 1987 A/C system

My wagon has a bad compressor that needs to be replaced, but seeing as I live in South Florida, and that we're moving into the hottest part of our already sweltering summers, I was wondering if there was anything that I could do to improve or upgrade the A/C system to be as cold as possible.

Are there newer and more efficient compressors that could be swapped in, for example?

The previous owner already converted the car over to r134, for what it's worth.

Envirosafe or Duracool refrigerants should get it plenty chilly. Parallel flow condenser is a good upgrade too, from what I've read.

Charge the system with Envirosafe ES12 industrial refrigerant and add a pusher fan in front of the condenser and it will get plenty cold.

Are there any drop in replacements available on the market?

By the 93+ 9 series condenser, which was factory R134a. Might not be drop in, but best available stocker.

I used a universal parallel condenser from ebay and it was only 54 bucks. I cut off the old mounting brackets and riveted them onto the new one and had two custom hoses made. I also used industrial es12 and got down to 40 degrees at idle. I actually left it idling in the driveway the other day and had condensation on the windows I have a 1990 with the crappy evaporator too. All in all including the new blower motor and resistor block I only have I think about 200-250(I replaced all the hoses, resealed my original compressor, and replaced the drier also) in it.
