What issues are you concerned with? The ZC intake will bolt straight up to the D16a1 head and will have to use the ZC fuel rail unless you can find a way to mount a different piece. With the use of the ZC fuel rail, you may need to build your fuel feed line to reach from the pass side of the firewall to the drive side of the rail. 

 

Another option is a P29 ZC intake. Its the best flowing intake out of four generations of dual cam motors. The only mod is the removal of the top center mount stud.

I am looking forward to how you make these 84-85 headlights work with the 86-87 header panel, side marker lights and grill.
 
I did the same conversion on my 86 CRX Si and found many little differences between the 84-85 and the 86-87.

These are custom made buckets specifically designed to fit the 86/87 front end.

As most projects go. Not much has been happening.

 

Took a chance on ordering a custom sedan front lip and 86/87 recessed headlight buckets.

 

The seller took great care in protecting the lip. He welded a metal cage around it.

 

You had my curiosity, but now you have my attention.

All four models are different. The 84/85 Sedan shares a similar design/shape to the CRX, but unfortunately they are not interchangeable.
