Ok, so I recently got a good deal on a JDM B18B with B16 transmission. I plan to put it into my 91 Ef Hatch STD.
All of the write ups i have seen focus on converting to OBD1 for the engine swap, but very little info on obd0.
I have gotten conflicting info on using the injector resistor box and not using the resistor box.

If anyone has some imput on wiring that would be very helpful.
Thank for looking!

 

If you're converting to OBD1 you use OBD1 injectors and "NO" resistor box.

If you keep it OBDO, you will use the original injectors and a resistor box...

 

Im caught up on the same thing. So i should get a obd0 resistor box out of a da. Any particular year? then just do the the straight up DPFI to MPFI Conversion?

 

you dont "NEED" to get rid of the box. my b16a2 is obd1 and still using the resistor box.

 

Completely wrong information. here is the correct info...

-if you want to use obd1 or obd2 injectors then you will need to eliminate the resistor box.
-if you decide to keep and use obd0 injectors then you will need to keep the resistor box.

 

obd1 and 2 injectors need a constant 12volt source. with obd0 they only use 5.5volts you can run obd1 with the resistor but run the risk of frying the ecu or worse. rywire has the injector info on there webpage

 

HEY WATS UP I JUST FOUND THIS SITE AND IM NEW I DNT KNO ANY ONE AND DNT KNO HOW THIS SITE WORKS BUT I WANTED TO KNO IF U HAVE ANY IDEA WHERE THE HONDA MEET IS THIS YEAR AND WAT DATE IM TRYNA GO DEEP I JUST STARTED THIS HONDA CLUB I GOT PEOPLE EVEN FROM FLORIDA IN THE GAME BUT YEA LIKE URE EF I GOT ONE OF THOSE HELLA CLEAN.

 

uhhh is this guy spamming or just being an idiot?
BTW crx_si-r is right on. Do what he said, with a proper OBD conversion, and you should be ok
