i'm not sure if this topic has already been brought up or not yet but since i'm currently having problems with my heater and ac(which works fine if it wasn't for my leaking heater core) when i do my engine swap i want to have a fully functioning airconditioner and heater do any of you guys have heat and a/c.. this wouldn't be a problem if it didn't rain all the time down here in florida

I have a fully functioning heat and A/C in my install. I got everything from Vintage Air, and the same would work for just about any Z regardless of the engine. The only engine specific item to work out is figuring out where and how to install the compressor and connecting it up with a fan belt.

ok thats cool... i was just wondering b/c i've been reading up on some of these rb swaps but it doesn't seem like anyone has brought up anything about an a/c swap... what do you mean about finding a place to mount the compressor? would i have to move it from the stock location to make it work on the car? and if i was to get custom made lines for the a/c system could i get them to work with the stock 280z setup?

basically if your car has ac in it, you don't have to disconnect any of the lines, or even remove the compressor to take out your engine and put in another. you may have to pull it to the side to do so but not disconnect it. now the issue lies in, "on my motor the compressor was at the bottom on the driver's side but on the motor that i just put in my car the compressor's supposed to be on the top on the passenger side" so in this hypothetical situation the solution would probably be some fabrication on the high pressure and low pressure hoses that go to the compressor, then making brackets that will bolt your compressor to your new motor, then figuring what belt placement/size/length or pulley you'll need for the crankshaft to turn your compressor, then once you've gotten that figured out, the wiring, then evac and recharge your ac and if it was workin before it should work now.

 

as far as your heat, once you change your heater core so you won't have a leak anymore, it's just a matter of running the two heater hoses from your new motor to the firewall and to your heater core and voila you have heat.

 

having heat and having ac are 2 separate systems, you can have one without the other. hope that helped, and good luck :D

I didn't realize that you can get the RB with a stock compressor. Z U L8R provided some good informtion on connecting your stock system from your car to the stock compressor on your motor. You should be able to make them work together.

 

Good luck and let us know how it goes.
