OK so I have a obd2 b18b out of an '01 LS and i'm putting it in my crx with a zdyne. So all I need to do is rewire the b18 to obd0 with my old d16 wiring harness correct? All the accessories on the engine (dist, allt, etc) will be fine being controlled by the obd0 ecu right? I searched like hell for this and i must just suck at searching or something.

i think you would be better off just runing obd1 or obd2 obdo kinda sucks i have a d16z6 in a crx with a zdyne and after spending big cash on my obd0 zdyne i realize i should of just went obd1

Your distributor must match your ECU.. I.E. OBD0 ECU.. OBD0 distributor.. most sensors should work over.

...as for this, that would be a retarded waste of money. The B18B is a non-VTEC motor. The only difference between running this motor and the motor that came stock in that car is the displacement. His Zdyne will run this this motor perfectly. The OBD1 conversion will be require a new ECU, new distributor, and wiring harness. $50/$150/$75.. That's quite a bit of money to spend for absolutely no practical no gain at all.

sweet thanks for the help, now im off to find a bseries obdo distributor. I dont see how obdo dyne could suck if you got it tuned right. incase anyne is wondering why i bought my zdyne it was about 3-4 years ago when there were no other rom editors (besides hondata) and i just have never thlought about changing it.

does anyone know if there are wiring diagrams for obd2-obd0 online? all the sensors have different clips and some diff wire colors.. is there a book online I could buy to tell me how to do this?

If they fit in the hole, use your old sensors. The intake manifold shouldn't be too big if an issue to plugin in.

Take pictures of the sensors and post 'em, and I'll tell you what they are, and if you need to change your plug.
