I have a obd2 h22a4 in my 2001 prelude and i am about to order a jdm motor. I want to stay obd2 so question is what would i need to swap off my current motor onto a obd1 h22a to make it work with my current ecu. I saw some places injectors dizzy and the crank sensor but sense obd1 has no crank sensor w ill it stoll bolt right up ??? Any help will be awesome

 

Swap the oil pump from your existing motor (or better yet, just buy a new one) to keep the crank sensor.
