So I have a 92 civic si with a JDM D15B. The A/C isnt all the great. Its just enough to keep from sweating. Im about to swap in a GSR. Is there anything I can do to make the A/C a little bit colder, and maybe blow a bit harder? Or anything I can check?

 

could go to a shop that could check the pressure to see if you need to recharge your ac.

 

^ x2 sound like a recharge

 

Are you going to use a/c with the gsr? If so decide on keeping yours and a adapter or a B series a/c

 

If you keep yours it seems like it would be less expensive on you, because then you would only have to have a shop check the pressure and possibly fill it... but im kinda confused is it just not cold or does it not blow hard enough?

 

You have a low charge and your system is R12, [no longer avalable] so you will need a retrofit to the new R134a system.

Biggest issue will be fit, will the compressor off your JDM fit the GSR???
If not, custom bracketing will be needed, changing the compressor to one that fits the GSR may be easier but you will have to make sure the manifold is the same or the A/C lines will not fit and they would have to be changed.94

 

Once you convert to R134, all you need to do to re use your AC system is get a P7J (Honda CRV with B20) or the del Sol VTEC AC bracket. They have the correct pattern to bolt the bracket to the block and to bolt the D series AC compressor to the bracket.

I agree you are probably low on charge.

 

r12 is no longer made, so if you find someone who has it in stock or recycles it then your good..
for me locally there is a shop that sells r12.. yes r12 yes r12.

 

Both, it doesnt blow hard enough, which makes me think i need a new blower, and its also not all that cold. Ill take it to a shop and have them check the pressure. Thanks for the tips. Would the GSR use a better AC compresser then the D series?

 

There will be no big diff. in the compressors, [efficiency] other then how it is mounted and the manifold.
If you can find a shop that will sell you a R12 charge, stick with R12, it is a much better refrigerant then R134a, it will save you some money as you will not have to retrofit your system.

That was the good news, here's the bad news, if you have poor air flow from your vents it could mean the leak you have is in the evaporator, when the evaporator leaks the oil coats the evaporator picking up dust that clogs the evaporator leading to low air flow, if that's the case you will need to replace the evaporator.

Not sure if that's a dash pull on a 92 Civic or not. 94
