obd2 b18b what is the diffrence to obd1 b18b
hello I'm going to swap out my old b18b obd1 for a low milage obd2 b18b. I would like to know what i have to change and what are the diffences in the motors,trans,ecm wires,ac,power steering lines. thanks alot for your help.
are you sure i've been told that you have to use obd1 distribter,injectors on the obd2 motor to use
It's all plug and play if you use the OBDI ECU......

Done several swaps with this method as well.

sweet that sounds good to me no need to swap out any parts on the motor just keep my stock ecu that so cool thanks guys
I think this needs to be clarified.
The obd2 motor is plug and play if you use the obd2 wiring harness(which will plug into your chassis harness w/ no problems)
If you are trying to use your obd1 harness, then yes, you will need to reuse your injectors, distributor, and alternator.
I just wanted to make that clear since it seems like everyone is just assuming you have the obd2 harness also.

thanks that makes the most sense so far do you know if the ac lines are the same and power steering as well? thanks for the help so far

Whoa buddy !!! Who is assuming here ???

OBD-2 Engine harness will plug into OBD-1 Chassis Harness and will work taking in consideration you will be using ODB-1 ECU as well
--- Hence the term "Plug-N-Play"
PLEASE REREAD MY POST!!!
This is what I said:
This is what you said:
The exact same thing.
Im referring to using the OBD1 engine harness(off of the OBD1 engine that he currenty has) on the OBD2 ENGINE(what he wants to switch to).
He never said he had the OBD2 engine harness. You never told him that he needed the OBD2 harness. So by telling him it was plug and play you were either ASSUMING he already had the OBD2 harness or you just dont know what your talking about.
