it can be done...you wont get the max potential out of the motor with an auto trans. Also, the ecu's that came with autos generally produce less power and all that good stuff. but if you arn't seriously worried about being the fastest thing on 4 wheels, go auto and build that motor and tranny up and suprise a lot of people with an auto. Im actually going to start working on a 91 integra ls turbo thats auto. Make it a sleeper and suprise a lot of people
I just did this a month ago. 4gen with H22A JDM Auto. It is easy. there is no additional wiring, just make sure you have the auto trans computer. The ecu is also badged as auto. Good luck. Oh and it makes the car what it should be, a nice sport sedan. The power is great.
swapping auto to manual can sometimes be very involved. If you know what you are doing it is fairly easy. For example, converting an automatic accord to manual you need the pedals, ecu, tranny, linkage, shifter and accessories, center console, gauge cluster, one of the mounts..i dont remember which..and you have to run new wires..There are some other steps but I dont remember off hand whatthey were..
so its very involved...but the pros definately outweigh the cons from a performance standpoint
well, an auto swap in a 6th gen civic is just a bit more of a hassle then a manual to manual swap would be.... three things
1) to keep things simple, get a b16 automatic with ALL the engine, and tranny mounts!!! (its gonna be hell to find JDM auto b series mounts in the USA)
2) your going to need a custom converstion harness (mine is being started on for 300 dollars.
3)don't have your heart on being the fastest thing on the road... cause its gonna take a little bit of work before you'll be able to suprise anyone....
