EA82 to EA81 A/C swap?

[spideyz]

Anyone ever taken the AC out of an EA82 and put in in an EA81 without factory AC? Thinking about doing it now that summer is here and my 89 wagon sits dead (but with good AC) and the 87 brat is without AC.

um... uh.... ok, I'll keep quiet.

But anyway I have AC on my ea81 and none of the parts look interchangeable. Might be more of a nightmare then it's worth. You would be better off going to pnp. But I'm not positive on that one.

i put ea81 motors into ea82 bodies, using ALL ea82 components.

both used the round style inboard compressors.

 

aside from my application using the ea82 water pump, here is what you will do:

take off all the ea81 original anciliary devices. the ea82 ac/alt bracket will fit on the holes on the ea81 heads, the 12mm bolt on the top, and one of the 14mm on the front. the alternator and ac will be slightly spaced forward past the crank pulley, but its not that bad of an offset.

 

now, the alternator will sit farther back with the ea82 brqcketry, but an alt with the 2 pulley(non ac equipped ea82) will make up that space(i welded a double pulley for mine. everything will be in line for use of the ea82 power steering pump(use the ea82 lines, run them to the ea81 rack)

 

take a good look at an ea81 turbo, as it uses the ea82 style ps pump, and alt bracketry. that will give you an idea of how it will all fit to the ea81 block

 

this is how it all physically fits to the motor, but i dont know if the ea82 air conditioning lines will match up to an (ac equipped) ea81. mine used ea81 motor with ea82 components in an ea82 body.

 

i would suggest having all the parts at hand for comparison before you make the conversion, but its not impossible at all
