I've been wanting to put A/C in my '89 Civic for years now, but it's pretty hard to find a junker with a complete system in my part of the country (Atlantic Canada). The oldest Civic I can find locally right now is a '94, I wondered if the A/C components would be similar enough that I could swap them without too much difficulty.
Or if someone has a complete A/C system for a 4th gen Civic they want to sell, that would be great too.

 

They are not very similar. The pipes through the fire wall and the condenser are completely different. Nothing would be "bolt on".

You would have to switch to a side by side radiator / condenser and those are probably too tall for the EF engine bay.

I see what you mean. I guess I'll have to keep looking for a proper fit or a cheap universal replacement.

 

What is your budget? And what all do you and do you not have?

You could piece together most of the firewall-forward pieces brand new from Rock Auto for ~6-700 it seems.

 

Afraid I don't have much of a budget to work with, probably around $150 would be my limit.

 

It would cost that much just to charge it!

 

^What he said.

 

All of the common replacement items are still available from the auto parts stores. You may as well check there first. Things like lines will be more difficult.
