Default Coverting OBD 2 to OBD 1

Ok, well I tryed searching for this topic and got some results but i still have questions.
What is the name (number) of the ecu that i should use in this conversion?
I have basic bolt ons, and within a few months will have cams and springs.

Also, i have the wiring harness. Plus the ecu, is this all i need? Just plug it in and go? Do i need to mess with the distributor or anything else?
btw, i have a 98 gsr if it matters.

thanks for the help guys

if you want a ecu where you can just plug it in a go, then you will need the obd1 p72 ecu(found in 94-95 gsr's)

p28 is from 92-95 civic ex/si

to make a p28 work you need to have it chipped with a dohc vtec program (skunk2, mugen, jun etc.)

or

hondata

chipped p28 being the cheaper of the two.
