obd0 to obd1 conversion

Postby hondacodes » Sat Sep 22, 2012 11:30 am

Hey guys I'm trying to convert to obd1 from obd0 in my 89 Rex. I have the a6 block and z6 head. The distributor was put on where only 1 of the bolts is on so I plan on get in a new one. My question is what parts do I need to get. Reason I'm doing this is because I plan to supercharge very soon and have new injectors and want to tune obd1

Do I still need to buy obd1 dizzy? And will I have to buy a new ecu? Would it be better or possible to go obd2?

But you can also use a obd2 distributor.

Yep, only first two links don't work..
yep also sub-harness makes everything simple, i've used rywire's complete obd0-obd1 swap.. had 0 down time with wiring on a 2000 b16a2 into a crx si..
Yes you will need a 4 wire o2.. get it for a 92-95 civic si or just reg civic..
Do you have a build thread? I would like to see the jrsc.. :-)b

When I converted to OBD1, I had to first convert it to MPFI (I have a DX and did this part myself). Then I bought the Rywire ecu adapter harness. Totally worth it. It was more time-effective than doing it myself.

Since I'm doing the same swap with my B16a1, and boosting, I have a question.. I was told by one of the guys at rywire that I would need an injector adapter harness as well if I planned to run larger injectors than roughly stock. OP is doing DSM 450cc and I'm looking at 750cc. Do I need an adapter, and does the OP? I've asked a few friends who've done similar swaps and gotten different answers..

Blue or black top inj, blue tops which is what I have on the JRSC setup didn't need anything just plug and play.

If its low impedance (blue) its plug and play like Dave said.
If its high impedAnce then just remove resistor box

Interesting... So I thread-jacked by asking a relevant question which had a direct bearing on the OP's thread and build (which just so happens to correlate to my own build), but may have been overlooked since it wasn't mentioned anywhere in this thread or in his build thread.. Oh wait.., he has a black top injectors.. I wonder if he needs to do anything for those :|

Good luck on your swap and build HC, I'll be starting mine sometime soon too.
