for better cooling ?
Yes u can, because R507 and R134a use the same type of oil. So u should only recharge your system. But remember that after this your compressor will be more hotter and u may be would need another captube length

If you charge the system correctly you do not have to change the cap tube.

The cap tube needs to be sized for the load and the refrigerant. It may or may not need to be changed. We don't know what you are working on, or what size cap tube you currently have, if any, so how can we possibly know if it needs to be changed?

Does some one want to reach through the Screen and say, "Look this is what you do....... No no no.. Dont do that" ?

pc ice you make -100C sound easy. Setup looks good and it's good to hear that R134a compressors are good cuz i just got one :)
what size compressors are they pi ice, do you buy new ones or are they similar to ones used in fridges

I would say that it depends a lot on the compressor if it can handle R507 instead of R134a.
Sure, the oil is compatible, so that's not the big point :)
But from what i understood, the pressures in the system will be higher with R507 so the compressor should be able to handle these pressures.

I also read in some posts that compressor size isn't very relevant to cooling power. but I always thought there was.
because of the cylinder volume. am I wrong on that one?

Well sure "size does matter"
But its not how you start out designing your system.
1) Total max load
2) Evap, Metering device, & Refrigerant that can preform the task.
3) Size up a compressor/condensor (These are usually larger than whats needed. Just the nature of the beast.)
4) pipeing size
5) build and test.
