what all does it take to put a zc in an 84-87 crx

 

Putting the 86 'teg engine (almost the same swap) just required modifying one of the mounts and having an almost complete donor car

 

Like he said. If your cars an Si than its a very simple swap. The motor bolts right in,minimal work. If your car isnt an Si and is carbed than its a whole lot more work. Youll have to swap the car over to fuel injection which makes a donor car very helpful. Its a lot of work but it is possible. The mounts would work, its the wiring and the fuel system and lines that make it so much trouble. It is possible though ive seen it done. HTH!
