Hey, i need some input here. My girl friend drives a 95 civic sedan (4 door) DX automatic of all things. and no matter what i can not talk her out of the auto. I myself drive 5spds and have a few of them.
Im no stranger to engine swaps and customizations. What i wanna know is what else do i have to think about when putting my old ls vtec mild built engine in her 95 auto with a 97 ls auto tranny. I have a 97 auto teg parts car. I figured most the mounts wouuld be the same (as in general motor swaping mount useage) until i got to the tranny mount and the d series auto mount is different than the B series integra auto mount.would i dare venture to say i have to cut and move the mount bracket back and adapt the auto teg mount to the eg mount bracket? and since im obd1 and have a chipped obd1 computer i can tune it out, or just rock an obd1 auto teg tranny right? any input will be greatful. i can provide more details if you feel im missing something. thanks

automatic ls/vtec how interesting...

dirtrdr22CRX

yea i was thinking about a turbo, ls vtec auto. constant boost cause the butter fly would never close. wot and the tranny would shift with out missing a beat so the boost would be full on until you stepped off the pedal.
but back to the main story. gotta figure out this auto swap before i just go and put her car up for a weekend and drill and cut and weld

I don't think a auto LS/vtec with even work.
What ECU would you use? How would you tune it?


A auto B swap will be doable in the car, but I don't think you have any clue about how much work it will be.

A auto B has been done in a EG.

What year is the integra you have?

I wonder if you be able to swap all the wiring from the integra into the civic. In my mind that would the easiest way to do it.

THIS IS INTERESTING!
PICS!

a pain in the *** job, helped my buddy do a ls auto swap into a 99 lx. big headache!! good luck though bro

You can do a basic LS swap but it's a royal pain in the *** due to the TCM wiring and having to fab up mounts. LS/Vtec isn't likely to happen as there's no way to tune it (i don't know of any tuning software that supports automatic transmissions)

Cynical 1

my suggestion would be to split the wiring harness, and use 2 ECUs - one that is tuneable for the LS/VTEC, and a stock auto computer to run the transmission...

only have what is needed running into the trans ecu, and the engine functions and the rest running into the engine ecu...

or, buy JDM wiring harness for the engine and trans, and run a JDM automatic B-series ecu...

You would have to run power to both ECU's, but that would work. But then you'll have two ecu's to find a home for. The DSM guys use the auto-tranny's all the time. My buddy has a "shep" tranny and gets like low 11's high 10's in his car. They are fun if you do it right.

why even bother. honestly if she wants to have an auto tell her theres no way to do it. Easy fix, that way you can either do it your way and make it a 5 spd or not have to even bother with it. kind of a win win situation there lol.

Thanks for all the responses, yea i know. its kinda an out there job. but i find it intresting as well. Im no stranger to tuneing, but i know you can not chip and tune an auto ecu as far as im aware. but runnign 2 ecus is no problem. thats a quick wire up job. a straight ls auto swap seems more probable so ill just take the vtec head off and save it for another day. well i can keep it on there and just run it as is with no vtec. I kinda want that AH factor when the hood is popped on her car and everyone is like auto b? im lookin at getting it done by honda tech seattle.
My integra parts car is a 97, but i have no problem sourceing an 94 for 0bd1 control. and the auto tranny parts. i figured i could just swap all the harness fromt eh 97 and make the eg 0bd2 and wire up the chasis harness as it needs to be for inside controls?

Its more than you think. The throttle body on a manual car is designed different from the automatic version. Map sensors are different for communicating to the ecu as well. I am pretty sure there is a lot more different **** so save yourself a pain in the *** just so your "girl" can drive an automatic ls vtec.

dirtrdr22CRX

everything on the Ls vtec is 90% off the auto ls teg. i have both throttle bodies and they dont look different. map sensors and stuff and all the crap for the auto tranny is all there. i have full complete cars. well the teg is wrecked and salvaged. but its all there. other wise, id jsut put her in that. both cars are auto, eg and ls, so its a quick swap and plug and play when i look at wire harness diagrams in both books. its jsut a game of wire chaseing and welding. its a challenge dont get me wrong. Im just looking for other peoples inputs and insights on the challenge

It would be an interesting setup to say the least. That's why I already sourced the OBD1 B16 auto trans, all brackets, cables, throttle body kickdown cable plate, etc.
Good luck, I heard getting a DC auto trans in an EG, while doable, is a major undertaking, while the JDM B16 auto trans is a M24A, just the same as the D series auto trans, just different bellhousing to mate to the B series.

DSMs are not Hondas there is a difference, one of the biggest being that honda automatics don't use a planetary design like every other major manufacturer.

Any pic's or proof?? You would be the first the first person I have ever seen do a auto swap in a 96-00.

dirtrdr22CRX

I am going to have to look into that. im sure they are hard to find. i heard a kid talking about one one time. never thought about it tell now.

Finding the M24a B series trans is easy, it's finding the t bracket, passenger side mount, kickdown cable, etc. that's going to be the hard part. I visually compared the B series M24a to the D series M24a and there are very few differences, the dimensions are the same and the electrical connections are exactly the same.
I have one sitting in my basement and can compare dimensions to the D series you currently have for comparison. I have seen one EG sedan with a B16A auto swap and he claimed it was a bolt in affair, I didn't notice any alterations in the engine bay, but didn't have much time for a detailed examination. I am only waiting for a EG auto to fall into my lap before I go ahead and try this for myself, so I can have actual hands on first hand experience.

dirtrdr22CRX

sweet man!!! im looking at a few b16 autos right now. ones right in my area too. just in seattle. so thatll be a quick drive. yea i got a sedan with a d15b7 in it with the auto, forgot auto code but its the dx trannny, gutless wonder but great gas mileage. so if i get all the mounts and what not for the auto b tranny, maybe it wont be that hard to line up and be close to a drop in affair.

94EG8

If you use a B16A M24A auto tranny you'll need to run an automatic P06 DX/LX ECU on the LS.

If you go for it, please, please, please take pictures and document it, there is so little information out there on auto swaps. I just don't have the funds to drop on another car, I have 4 already.

Wouldn't you be able to run the JDM P30 auto ecu as well? Or any OBD1 auto ecu? I was planning on keeping mine all original B16A and Auto trans running on a JDM P30 auto ecu, no chipping necessary.

dirtrdr22CRX

sweet. good call on the ecus. and yes. i will be documenting this!! not just for me and my work portfolio but it will be going up on here too!! if the weather strats brighting up out here in Wa, ill be able to go out and work. i just have a car port and a shed for all my stuff so i kinda freeze in the winter months.

Yeah I feel your pain, I did my last engine swap on the cement slap outside my basement doors. I don't have a garage, so my basement doubles as my shop, the wife hates it...lol
And I am in Wyoming, land of -40* in Dec-Jan. hahaha

dirtrdr22CRX

oh yea man. you got it bad!! i did an 7mge 86.5 supra build out side in jan and caught pnemonia from trugeing back and forth from out side to inside. me and the girl are looking at houses and the main requirement is a garage!!!!
I have one of them propane jet heaters for working but outside it just warms in its direct postion so its still cold every were else
