r12 to r134a ac conversion
i have a 91 coupe that lost its engine. while in the process of transplanting, i have considered converting to 134a since my ac is not as cold as it used to be. i dont know anything about ac systems, and was looking for someone who maybe has already done this to save me the heartache of doing it wrong. thanks.

If you want your AC to blow colder r134a is going to do the exact opposite, stick with R12, it is more expensive but it is worth it. If it isnt blowing as cold it may be low a couple of ounces. If so, just go ahead and have a complete evacuation done and refill it with new R12, as opposed to topping it off. The capacity for the Rx7 is 30 ounces of R12.

Have the r-12 re-claimed, then have it charged with R-414b, it will run a bit cooler than r-12, but is cheaper than 12. Its a drop in replacement for r-12, no hose, drier or oil replacement required..Max

Hear is a boat workers site which has an "expert's" opinion of the R-414. Fishermen often have to have huge refrigeration systems on their boats, and they use the same refigerants as you find in cars. http://www.dockwalk.com/issues/2000/...hillout1.shtml The guy said that it isnt a good refrigerant to use if you have a leaking system, since it is a blend and will "fragment". It also says that charging is a bit more difficult since you can't use the sight glass to determine if you have the right amount.
