What is the difficulty on converting a car to obd1....cause i have a USDM B17 swap, but i have a JDM PR3 OBD1 ecu and wiring harness, and i dont know if its gunna be better to go OBD1 or just change the stuff on the motor to OBD0, someone please give me some info, and thank you in advance

 

You might run into problems if you have OBD0 and OBD1.

 

I think it would be easier/ cheaper to go OBD1. You already have a obd1 distributor and ecu...

since you have the wiring harness you can either do the wiring yourself or purchase a obd0 to obd1 adapter to plug into the stock wiring harness roughly $125

then all you would need is a 4 wire O2 sensor assuming you dont already have one.

so you have spent no more than 200 to go obd1

or..

you can buy a obd0 dizzy $150 used
and a obd0 ecu $150 used
then you will still need a second o2 sensor $50 new

you decide... price estimates are rough, but you can see which should be cheaper
if you go obd1 and ever feel the need to get hondata... you wont need anything else

 

look man i converted to obd-1 when doing my z6 and it wasnt hard at all i had to convert also to mpfi but its pretty much just replacing plugs in the engine part in the harness it was easy but i ran into problems cus i forgot to hook up two ground wires the grounds the ecu to my injectors and it would not get fuel but besides that....it was all good oh yea get a harness from blownhatch or kenji i have one from kenji it made it so much more easier look here is a link http://www.geocities.com/chipm....html

 

well i believe its gunna be OBD1 for me so i can run stage2 Hondata
