2nd Gen B16 In A 88-91 Civic?

[B16RacerN2NR]

I have an 89 4 door civic and me and my friend put a 2nd gen (obd-1) b16 in it. i'm having a problem tho...i'm using a pr3 ecu but apparently it's not working properly with the distributor...could it be because that ecu is pre obd and the motor is obd-1? i'm pretty sure it is but my real question is what can be done to solve my problem? get a obd-0 distributor? that's what i am doing right now but i want to know what you guys think. the main problem is that the rev limiter kicks in at 3200rpm :unsure: the ecu is reading a code 4 which is crank angle sensor...any help would help me alot

Mechanically,I believe it is the same as the siR,but electronically your going to have some issues,not that bad though.From what I gather you need the harness and adapters to put it in,and ecu from the car the motor came from to accomadate the OBD II.The OBD 0 ecu isn't going to work,your going to need the P2T that goes with the OBD II motor.Or OBD 0 distributor.

if you are running an obd-0 ecu and the stock obd-1 distributor, then yes that is probably your porblem. go get an OBD-0 distributor and see if that fixes your problem.

no my motor is obd-1...i say 2nd gen as in SiR-2 not b16a2...some people told me that they've done this swap before and they swapped out the distributor for the 1st gen (milky white connectors) and still used the pr3 ecu...anything else i could do that would help me? anyone? thanks for the reply

Sorry,lost my mind for a minute there.But really the same should hold true,just in OBD I terms using the distributor to match teh ecu.

thanks for the help huys...anyone else have a take on this?

ok... i have the same setup... you are going to need to swap the dizzy out for a 1st gen b16....also you may just want to see if you can swap out your exhaust manifold for the one that uses dual o2 sensors....if you have any questions you can pm me...

 

[B16RacerN2NR]

paybac...what other problems have you had? right now i have the stock ls exaust manifold on my car right now because i had no down pipe for the b16 one...which i have for sale if anyone is interested ...anyways... the ls one has the o2 sensor right on the manifold itself...i was just going to run both o2 sensorwires to one sensor itself...that's the only thing i can do right now...you have any other suggestions? thanks

bump: anyone have a idea???

with the dist. u have to use the obd0 dist with the obd0 ecu your car will not run right with out it..unless u rewige ur existing dist which is a process i dont know much about but ya run the 2 o2's from the one u have on ur manifold i did that with my d16z6 setup because depeng on my mood i swith from my obd1 p28 to my chipped pr3...and everytime i change the ecu i change the dist from a obd1 dist to obd0 dist.....

thanks guys

TO a Conversion to OBD1 ECU and Engine Harness!!

The question is how much you wiling to spend people charge a grip for these wiring.. good luck..
I am doing the same swap.. wiring is a bitch.. if you don't know anything like me..

DONT do that. running 2 o2's into one sensor is a VERY bad idea. just run the primary for now, and it will throw a code- but it will run.

the distributor needs to match the obd of the ecu. so swap that for an obd0 one. you might need to cut/paste the plugs from the obd1 harness to plug it in. thats where your manuals come in.
