I have a 91 si civic, it came with a b16 0bd2 head from 00 si and 0bd0 block setup running a pr3 ecu. I took out the swap and have a full 0bd1 b16a with a p28 ecu swap i want to put in but not sure what i need.. just the rywire 0bd0 to 0bd1 conversion kit? thanx for any help

 

P28 4wire o2 ecu and dizzy jumper

 

you will need the obd0 to obd1 ecu jumper
obd0 to 0bd1 distributor jumper(you cant use obd0 distributor with obd1 ecu)
if you use obd0 injectors you will be fine but if you use the obd1 you will have to remove you resistor box and trim the inside of the injector clips
you will need to wire in vtec, oil pressure switch and 4 wire o2 sensor
and if your using a hydro tranny you will have to do the cable to hydro swap

thats all i can think of right now if anyone knows anymore feel free to chime in

 

the swap i have has the engine harness (0bd1 setup)... i was wondering if i all i needed was to order this... http://www.rywire.com/catalog/obd0-m...efbc96954e7fb6 .... sorry i work alot and try readin about the conversions it gets confusing.. i dont get how they ran a obd2 set up on pr3.. and some1 told me pr3 is the better computer.. i will get pics of the build up soon..

 

you cant use an obd1 harness you have to use your stock mpfi obd0 harness, are you trying to say they used a obd2 distributor with a obd0 ecu

 

no im not sure of that...i just know it had a 2000 si head..i have two not sure the diff. but i know 1 is 0bd1 for sure... so i just keep the same engine harness and get the rywire jumper/conversion..?

 

from my first setup... and not the 0bd1 right?

 

ok i get what your sayin now, yeah the head doesnt matter if its off an obd2 car as long as the distributor matches the ecu, just use the distributor off the motor thats in the car now, its got to be obd0 since your running a pr3, and use the pr3 and you wont have to get that jumper you can just run it obd0, unless you wanna convert it to obd1 then yes you need that jumper for the distributor and ecu other than that all you previous stuff will swap over
