Which air con to use

[wally57]

Ive got two air conditioning units that have both come out of 1977 260z 2+2's. One is an underdash unit that attaches to the firewall above the front passengers feet. The second is fully intergrated into the dash with the evaporator mounted right up in the centre of the dash. I had intended using the second fully intergrated unit but I've been told I should do a bit more research before deciding which unit to use, because not all of the systems available work all that well. Can anyone give some advice on which unit is the most effective.

I have both types as well but went with the hidden unit even though had heard they didn't work too well.

Found it works great. Put in a new "ice" compressor which is way smaller than original for $300.

There are different rated fan units. Try to put the one in with 4 speed fan and higher rated wattage blower motor.

Thanks for the advice, I was hoping that would be the case as it's a lot neater installation. I have to buy a new compressor anyway so I'll have a good look at the ICE unit as you suggest.

Just ran across the receipt. It was $500 not $300.
