Re: * * OBD1 B-series engine into OBD2a/OBD2b civic/integra * *
Question about the OBD1 Distributor, does it have a CKP sensor inside of it? as opposed to the OBD2 Distributor where the CKP sensor is external?
I just swapped a OBD1 B18c1 motor into my OBD2 98 Integra GSR. There is no spark, Im trying to use an OBD2 distributor <it plugs into my OBD2 harness> but im wondering if there is no spark is because the OBD2 doesn't contain the CPK or TDC sensors the OBD1 ecu is looking for? or am i off base in my thinking.

If you're reusing your 98 GSR ecu with an OBD1 dizzy
You might wanna crack open your OBD2 dizzy and see if the internals are all there (igniter and coil), also maybe, your ignitor or coil has gone bad on the OBD2 dizzy, hence the reason the vehicle won't start.
Are you getting a CEL at all? if so, what code is being flashed?

Re: * * OBD1 B-series engine into OBD2a/OBD2b civic/integra * *
ok dont flame me lol im tired and just ran into a bitch of an issue that i have yet to see in all my years of doing motor swaps. first off the car being swapped is a 99 ex coupe. doing b20 vtec swap for a kid. head is from 99-00 si, came across an issue when i noticed that the distributor plug on the harness is tiny and will not fit any b series dizzy plug. so i went ghetto and hacked the plug off the original d16 dizzy and attempted to splice it onto the b series dizzy. almost everything matched up fine until i got to the light blue and yellow wire on the dizzy and the dark blue wire. noticed that the light blue and yellow wire had silver wire in it and there was only one wire left on the d series dizzy plug that had silver wire in it so i spliced it together. (this was simply an experiment cause the kid plans on buying a new distributor) well i ended up having only the dark blue wire left (copper wire inside) so i left it hang. car fires up and is not throwing any kind of ignition or firing code. so my question on that is uh is that gonna be ok? also we are using obd2a y8 ecu still till his p28 and harness come.car is hitting vtec but is throwing a code for the vtec spool solonoid, my question for that is why is that code being thrown? is there a conflict with the y8 ecu? car is only throwing 3 codes (primary 02 which i can fix, ckf no duh, and the vtec spool solonoid). please excuse my grammar or lack there of and my lack of knowledge on this, never seen that little plug before or dealt with obd2b. any help is appreciated.
It's quite ok to leave that extra dizzy wire hangin; that's actually required when swapping the bigger dizzy plug over to a 99-00 EX dizzy.
VTEC spool is the actual vtec solenoid wire (not the vtec pressure switch ie. green solenoid housing). Do you have this wired in?

Re: * * OBD1 B-series engine into OBD2a/OBD2b civic/integra * *
yea, the car was an ex so it already had both plugs for the vtec pressure and the vtec solonoid. the car hits vtec around 5300 like normal. we are still running the stock ecu that came with the car (sohc vtec obd2b). i figure the only issue with that ecu is that its only gonna rev to like 7200 rpms and have a speed limiter. now when i do get his p28 and harness. what wire do i splice the rpm signal wire into?

OBD1 dizzy's do have a CKP internally and are compatible with OBD2 ecu use, but you still need to have the external CKF plugged in as U.S. OBD2 programming looks for this sensor.

Do you have access to another dizzy to test out? perhaps your igniter or coil is going bad, or something else (have enuff fuel?)

It sounds like in order to run an OBD1 motor you need an OBD1 dizzy? unless your going to convert to OBD2 and use an OBD2 harness and install the crank position sensor by the oil pump.
OBD1 ecu, conversion harness, OBD2 engine harness, OBD1 motor, OBD2 dizzy, OBD2 sensors and alternator is what im working with. Everything is installed and connected. Just not sparking. I tried with another OBD1 ecu as well, but still no spark.

Re: * * OBD1 B-series engine into OBD2a/OBD2b civic/integra * *
The distributor im trying to use is an OBD2 <it plugs into my OBD2 harness>. Ive tested the coil and igniter and they check out. I dont have an OBD1 dizzy, but it seems like its not going to start without one.

Why you're not getting spark is beyond me at the moment.
Do you have the spark plug wires routed correctly on the distributor?
Sufficient amount of fuel in the car?
all grounds grounded?
any CELs?

Hi Katman,
My EK is running! it's 2000 GSR with Blox IM into my 96 EK. running obd1 with a chipped p28. Just wondering, does the CFK by pass trick still needs to be done? I have not check the CEL for codes yet...

Not to sound like a dik, but does anyone read any of my previous replies?
No need for CKF trick if converted to OBD1.

Re: * * OBD1 B-series engine into OBD2a/OBD2b civic/integra * *
What if I need the opposite? I have an eg with a 01 gsr swap.. I just bought a eg with a gsr swap and I need to double check the wiring... The car has a p30 ecu and for some reason it bogs while driving... When I give it full throttle it just completely stops... It has to be a fuel problem or wiring... I noticed where the dizzy was spliced that the wires needed to be done... Haven't looked at the injectors yet... Wha could it be? Tomm Ima check the injectors since they had to be spliced to see if that was the problem but what do u guys think?

Re: * * OBD1 B-series engine into OBD2a/OBD2b civic/integra * *
ok im hoping for some quick help here. putting a b18a1 into my 98 ex using the ex harness making the motor run on a 97 integra ecu so it will pass emissions. right now i have the motor hanging over my car started to hook up the wires and one of them has 2 pins in the plug and on my d16 what i thought was the same thing has only 1 pin( or possiably got broken while removing it???) i was told on my d16 that the plug is the knock sensor but what i thought was the same thing is oil temp or something else. i need help or a link to pics of the plugs and what they are or something
pic of plug that is in question on my b18a1, what is it for? the green one

also does anyone have a link on people hooking up there ac and power steering with these swaps? im putting my b18a1 into my 98 ex and when i got the b18 it didnt have ps or ac so idk if they use brackets to bolt to the motor or just bolt right to the motor and if they use brackets will that allow my 98 ex ps and ac to line up correctly or do i need them out of the integra? thanks

If you wiring looks haggard around the distributor, there's no doubt in my mind that could be the source of your bogging problem as well as the injector plugs (loose connections perhaps).

That green plug is either an oil pressure sensor or water temp sensor (forgot), its one of the two though. If you only have wiring for 1 of the nipples, just try plugging into one of the 2 nipples and see what happens.

As for the mounting of the A/C goes, you need to pick up a P54 A/C bracket (from a DOHC Delsol) which will let you retain your D-series A/C compressor while using it on a B-series engine.

OBD1 B-series engine into OBD2a/OBD2b civic/integra
1. Can I use obd2 JDM GSR injectors?
2. I have a 99 gsr, does it matter if I get an LS obd2 injectors/alternator/distributor?
3. I'm using obd1 ecu, which O2 sensor should I connect (before or after cat. conv.)?
4. IAT sensor plug: how small/large should I make the hole in the intake manifold arm and what's the reason for doing that? Do you have image?
Thank you very much for all your help!

Yes

does not matter, regardless of OBD2a or OBD2b, they're all the same parts and plug types. The ECU is where it differs
3. I'm using obd1 ecu, which O2 sensor should I connect (before or after cat. conv.)?
before cat (primary 02)
4. IAT sensor plug: how small/large should I make the hole in the intake manifold arm and what's the reason for doing that? Do you have image?
OBD2 integra's use an IAT sensor thats located on the intake manifold runner. You don't need to drill or modify anything. Only 96-00 OBD2 civics use an intake pipe mounted IAT sensor.

1. How about the engine wire harness-does it need to be obd2 GSR? If I get an Ls one does it effect the Vtec?
Thanks!

Re: * * OBD1 B-series engine into OBD2a/OBD2b civic/integra * *
OBD1 and OBD2 integra engine wire harnesses are compatible with OBD1/OBD2 integra's and 92-95 civic chassis's. So it doesn't matter actually. But to alleviate any kind of confusion, if your integra is OBD2, stick with an OBD2 integra engine harness. You can use an OBD2 LS engine harness, you will just need to add the required wiring for VTEC to work (vtec solenoid and vtec pressure switch) and the knock sensor as well (Unless this is disabled in the programming).

Re: * * OBD1 B-series engine into OBD2a/OBD2b civic/integra * *
ok.... it FIRED! for 2 seconds.
well, sorta anyways. The main relay was making a clicking noise as soon as the key was turned this entire time. I pulled the radio backup fuse <reseting the ecu> and the main relay would stop clicking. Engine would fire and start up for about 2 seconds then would shut down, and the clicking at the main relay would start back up. Only reseting the ECU will stop the relay from clicking. I tested the relay and it checks out. HOWEVER, i checked the resistance of the ground wire inside the main relays plug, it shows about 1500 ohms of resistance. Shouldnt that be zero? Is that a sign there could be a wire grounded somewhere or a bad ground connection? The valve cover, trans and battery grounds all look great.

Katman,
How bout the injector clips that is connected to the harness, can I use any obd2 fuel injector clips to clip onto obd2 fuel injectors?

Honda didn't change anything with the injector connector and clip design, hence all OBD2 injectors are compatible with OBD2 injector clips regardless of OBD2a or OBD2b type.
