did this swap in a dx but you have an si so no worries about wiring. rest is as simple as pulling the old motor it is a direct bols in, not sure if you can use the zc tranny without finding a weird axle combo. but could be wrong. if you si tranny is decent just use it with a good clutch. good luck si ecu will work. or 88-89 integra i s common to i think.
