if by "pgmgi" you mean the dual point injection d15b2 engine, it's not
quite so easy to drop in the zc.  you'll need to convert to 4-point
injection, re-wire accordingly, and get the relevent ecu, etc.

if you just replace the d15 engine with another, they're dirt cheap.
definitely cheaper than rebuilding your old one.

HI,

The ZC is one heck of a engine.   128HP vs 96HP.   It's a noticeable
differance.  I had one in my old 90 Hatchback.

You could run the your DPFI intake on the ZC w/o any issues.   I still
passed the e-test with it on my zc.

Going from DPFI to MPFI isn't too hard.   You can keep your ECU.
You'll have to get a few more parts and re-pin some wires on the harness.
Just google search  DPFI to MPFI .  There's a lot of info on how to do it,
parts needed, etc.

Make sure you replace your t-belt, tensioner(maybe), & water pump with the
engine out. Also install a new clutch.

$500ish engine  $200 for t-belt/waterpump, $200clutch kit,  MPFI if your
decide to go that way $20-$30MAX from the junkyard.

You may want to check out www.hondaswap.com fourm.   There's a lot of info
there.  Just make you SEARCH before making a post.

Also I would stay way from the DOHC version.   It's a lot harder to find
parts for.  SOHC ZC basicly shares parts with the Si D15/D16 block. ie. same
t-belt, water pump, etc.,
