what all do i need to convert my 90 crx hf from odb0 to odb1

 

do i need just the engine harness or the inside and tailights as well

 

talk to kj at zmr he can tell u want u need
but if u ask me I would keep the pre obd for a sohc motor
if u want obd1 your looking for a wiring nightmare & alot of$$$

 

It is not too bad. You'd need an ecu jumper harness for the ecu. You use the stock obd0 engine harness and modify the plugs for the obd1 motor.
Off the top of my head:
-Re-pin the distributor to accept an obd1 distributor
-you need to extend and change the plug for the coolent temp (fan) switch.
-injectors: you can install a set of obd0 injectors on the obd1 motor and run the wiring as is. If you run the saturated obd1 injectors you will need to bypass the injector resistor box by installing an obd1 power distribution plug.
-install the obd0-obd1 ecu jumper harness
-do the engine specific wiring, i.e) vtec wires, ect...

 

how much u think all that would cost

 

Cost for what, the ecu jumper harness is about $200. On my car I did all the other wiring so cost was $0.

 

how much would it cost for me to have u do it kj

 

I tried to pm you a price but your box is full. pm me when you clean it out.
