Alright, I'm going to be ordering my 98 or 97 JDM B18C GSR swap from Steve at HMO. I just want to make sure I got everything I need in order to complete the swap in as little time as possible. I was told a 97/98 JDM GSR engine is OBD2a, while my 2000 Civic EX is OBD2b. So, here is what I'll be ordering:

-OBD2b to OBD2a Conversion harness (http://www.boomslang.us/obd2to2.htm) <- possibly that brand?
-Rear tranny mount from 99-00 SI (50827-S04-N10)
-Driver Side mount bracket from 99-00 SI (11910-P30-000)
-'96 Del Sol A/C bracket (38930-P54-000)

Am i missing anything? I should be ordering all this within the next week. So i need confirmation as soon as possible. I'll be doing the swap myself, so also if you have any tips/tricks, let me know. Again, this is a 97/98 JDM B18C GSR complete swap going into my 2000 Civic EX.

 

Alright, just checked. the JDM engine ill be getting comes with a P72 ecu... which is OBD1 correct? so i would need a OBD2b to OBD1 conversion harness correct?

 

The P72 comes in OBD1, OBD2a, and OBD2b.

 

alright, so all i need to do is call HMO, have Steve confirm what OBD it is... and then just get the correct harness right?

 

Right.

 

alright, its OBD2a. so ill just get a OBD2b to OBD2a conversion harness...

now, about the wiring. will all i need to wire is...
Vtec Pressure switch
Vtec solenoid
Knock sensor
IAB solenoid (B18c)

?? my 00 ex alrdy has vtec so do i need to add wires for those 2? how do i go about wiring the other 2?

 

i hope your state doesn't pay attention during inspections... Or else you may fail inspection... and that would be no fun... Since they don't like older engines in newer cars... not that i care... just a warning... i mean... if they don't look... go for it... i would... in fact that's the same engine i want... except i have a 93 coupe... anywayz... goodluck\

 

For the KS and IAB wiring, if your engine came with the plugs already, and you plan on reusing your stock EX harness, then just cut off the two plugs and wires from the B18. Those two wires will have to be run from the sensors, through the firewall, then into the ECU. Going into the ecu you have two choices: get ecu pins from a junkyard, solder them on to the wires then plug in. The other option is to just jam the wires into the ecu plugs (worked for me).
