b18a1 into 89 crx hf obd0- obd1
okay i need someone that KNOWS what they are talking about here. tired of seeing hundreds off different stuff about this swap. i am looking for a full write up of what needs to be done todo this swap successfully and have it be OBD1 not OBD0. i already know that i need the obd1 ecu, obd0-obd1 jumper harness for ecu, people say i need new hubs cuz mines a hf is this true? some say i dont. i also know i will have to delete my resistorbox. i know i need integra axels. and all the other basics.

Dont delete the resistor box, just run your obd0 injectors.
Get the jumper harness, re-pin your dizzy if you want, it's really simple.
Get any OBD1 ecu, and run a new basemap on it (around $20) if you want.
Besides that, ask away. I did the swap.
okay my buddy is hooking me up with crx si disc all the way around. and i can just mix and match like that? i can just use a obd1 ecu obd1 alt, obd1 dizzy and keep the resistor box? and also do i need a base map or will my stock ls ecu work fine?
and im putting a obd1 intake mani on to get rid of that mess of vacuum lines on the firewall lol

i wanted to delete the resister box for a cleaner look, and by putting obd1 injects with obd1 clips on my harness would let me do that? by making the resister plug "dead"?

hey im doin this swap to and i was wondering instead of wireing it up for multi point obd1 what if i wasto get a complete engine bay obd 1 wire harnes would it work or wpould i have to wire up the engine bay and the uinder dash harness to obd1
if u go with the obd1 wire harness u will need to do the whole underdash bc the plugs in the engine bay where the engine harness plugs in are different. and urs isnt multi point fuel injected?
just use ur obd0 and u just have to cut your obd0 injectors plugs off and wire the obd1 ones on not hardd, and u have to extended some plugs. also needa 4 wire 02 sensor but on ur jumperharness for your ecu (obd0-obd1) will have a 4 wire plug on it which is ur 02 sensor
