Hi. My name is Eric and I am the proud owner of a white 1991 civic dx. I have had the car for a year now and want to do an engine swap . Problem is the wife can't drive manual, and she needs to drive the car. Now I know a b18 swap can be dome with a standard transmission but can it be done with an automatic tranny? If so how?

The best option is to swap another dSeries in there bc it will mount up to that trans.

That will be what I would do once I have exhausted all my possibilities but I know there is so much being done with the b engines I would hope there was an answer for me..btw thanks for the reply

Ive seen a bseries with an auto trans but they had to make their own mounts

eaps575

With the b series being as popular as it is I figured it has been done. Would you happen to have any links, pics, or any info on that? Thanks for the response.

Not many ppl want the auto trans. If you Google it, it might show up. But I don't have any info

eaps575

Yeah. Neither do I.lol But fair is fair so I have to get an automatic for my wife.lol

I'm paralyzed so I drive with hand controls which means I'm stuck with an auto. To get a b18 auto to fit we had to notch the passanger side frame, custom rh mount, modify rear mount, modify rh radius rod, and wire in the transmission control module which is 28 wires. So my advice is stick with a d or learn how to drive a stick. Way too much work IMO.

Thanks for the input. It's greatly appreciated.

Just throwing it out there, you could run a dohc zc.
Plugs right in. just need to splice in a dizzy plug and ecu.


I'm sorry, you said a dx. You need to convert to mpfi first

eaps575

If I can't do a b series auto swap in my ef what is the fastest engine with an automatic transmission I can put in my car?

eaps575

Dohc zc? Is that the 1.6?

eaps575

Is an ej8 similar to an ef9?

You could get some better solutions here for transmission repair .Hope this solves your problem.

While fabricating a mount for an automatic transmission in a B-swapped EF will be a challenge, the BIGGER challenge is trying to fit the transmission itself. I don't know if you have seen an automatic B-series transmission, but they are ALOT bigger than the manual transmissions. Not only that, but they are more cylindrical rather than conical like a manual transmission. Given that the B-series manual transmission extends beyond the passenger frame rail (and tucks somewhat under it), you will probably have to make extensive modifications to the passenger side frame rail in order to allow it to fit. So unless you MUST have this car with an automatic AND a B-series motor (and have LOTS of cash to spend),I would forget about doing this swap. Going D-series is a better idea if you need to run an automatic transmission.

Probably the best motor would be a D16Z6. It puts out 125HP vs 108 from a stock A6 (or 92HP from a stock DX motor). Plus, you can get the whole package with an automatic transmission and ECU.

But honestly, it might be better in the end to just get your wife a different car. Perhaps something good and reliable, but with no performance aftermarket (like a Corolla).

DONT PUT A ZC IN THATS WEAK!!! I BEAT A EG BUBBLE WITH A ZC (STANDARD)AND I WAS DRIVIND MY B20 AUTO 1996 COUPE

adrianek9

NO. ej8 is a coupe and 4door 1996-1999 ef9 is 1988 -1991 hatch wagon or 4dooor

adrianek9

NOT A GOOD CHOICE FOR AUTO!!!! U WILL BE A LOUD SNAILL THOSE MOTORS COST THE SAME AS A B20B NON VTEC 2.0 LITERS!!!! I HAVE THE SSAME THIT IN MY AUTO CAR AND THE ONLY CAR THAT EVER BEAT ME WAS A GSR EK HATCH BOLTONS
go DOHC its the same price

adrianek9

single gingle sucks get a dohc b18b1 or b18a1. b18 a1 would be better for u with the tranny cause of cable shifter but you still can put the b18a1 cable tranny on the b18b1 engine and you will still have more fun than a sohc any day or get a b20b like i was saying in my older posts b20 +b18auto tranny + ef = AUTOMATIC POCKET ROCKET SLEEPER

A B SWAP IN A EF IS EASY YOU NEED A B ENGINE ,HARNESS MOUNTS AND STOCK TEGGY DRIVE SHAFTS

Matt8314

Maybe easy with a manual transmissions. But I personally don't consider having to modify the passenger frame rail, fabricate a transmission mount, modify a rear mount AND modify the radius rod to be an EASY swap.
