I have B20B motor 2.0L (DOHC) non vtec with manual transmission, with a intake manifold that came off a 1990-1991 integra rs with manual transmission and have 1990 civic si wiring harness produced in Ontario, Canada that came with a 1l na 14 double overhead cam (dohc)honda 16v. OBDO. thats going in a 1990 crx. Already bought a jumper for a obdo1 to an obdo if needed. I live in ca, and already have everything that will make the motor pass smog , I need to know what ecu/ecm that will run the motor?

Very cool, I am in California too. I could have guessed I know you Honda guys will do anything to make it work lol. Let me evaluate your ECU could you tell me what number ECU you have for the B18a1? I think with that list of parts you are actually on your way to making the b18a1 ecu work with a b20b.

Your answers were clear and the diagrams were perfect. Dealer wanted $87 for an hour of labor and even I did it in 15 minutes.

EdUSA

HONDA PLATINUM was great. I really appreciate his help. I was ready to trade my new Honda until he told me to wait until I got 3,000 miles on it and my gas mileage would get much better.

SummerUSA

I took the Power Steering O-Ring service bulletin linked from JustAnswer to my Acura dealer, and not only did they no-charge the o-ring, they also replaced the power steering pump at no cost.

Gary RStevenson Ranch, CA

Mary C.Freshfield, Liverpool, UK
