BORED..thinking about playing with my old 85 crx si ...
Does anybody know if i can swap out the 87 headlights with the 85's?
I like the way they look better and where can i get a SI lip for the 85 for cheap
websites please

 

Even though this forum technically covers your generation Civic, most people here (including myself) mostly deal with the 88-91 models. I'd suggest asking at http://www.redpepperracing.com, those guys are very knowledgeable when it comes to 1st gen CRXs/3rd gen Civics.

i used to have an 84...
but some quick advise check part numbers... are they the same?

 

the part numbers are definitely not the same, if you've ever looked at the headlights he's referring to.
to answer the question though - yes they will work fine. I did it on an old 1g a couple years back. 87s look way better than the recessed 85's.
as for the lip, just go to a junkyard. I used a lip from an hf.
