i need a AC heater box for my E9
My car does not have A.C. ,but I want to install it,so basically I need everything to install A.C.
maybe not, but wedont know, he has to confirm it, yes the heater is independent from the ACYou don’t need a new heater box. You will need the AC specific heater duct though.
Some stuff interchange w/others. I think an evaporator from an E20 will work as well??
There are some minor differences among the supplied evaporators. Real OEM shows E3, E9, E21 same part number. Here is a photo of the E9 unit on left, E21 on right. Pardon the mess, cleaning staff had day off . You will see plumbing a bit different, but so what? May make attaching hoses easier. Plus, there is a upright plastic piece on top of E21 unit, can easily be trimmed away, if in fact it is in the way when positioned in an E9. Then intermediate piece fits perfectly. Dimensions same.There are two known complete setups on the market right now. A new forum member is in line for either. That means that there may be another complete setup available. A Deq mentioned they aren’t cheap.
I pointed Alan towards an e21 parts car in his neck of the woods. He needs only needs the case. Perhaps he can chime in on fitment if pulls the trigger.
