I have a 99 Honda Civic HX and I want to swap to a B18c Type R but can I still keep it an auto and get a new tranny? What would I need to complete teh swap? Please help me out!! Thanx!!

 

hybrid forum is that way ---->

So you want an auto b18c5? :eh: I'll just keep my mouth shut.

 

If thats what you want, then you'll have to get a auto b series tranny.

But I recommend doing the conversion to stick. not that bad on an Ek

 

LOL...Y would you do that to the B18C5 motor...

 

maybe he wants a really fast automatic

~boom

 

It could be that he has an auto now, wants to swap, but doesn't want to do the manual swap with it. It kinda makes sense.

The only problem that I foresee is deciding which ECU to use. I know that manual and auto ECUs are different and that the TypeR didn't come as an auto. Andy or PHiZ may be good people to ask about this.

As for the mechanical part of this, any auto Bseries tranny will bolt up to the motor.

 

The auto will bolt up, but to my knowledge, your stuck with an LS automatic tranny. Supposevly there are B16A automatics in Japan, but I haven't seen one sucessfully swapped into a Civic yet. I know one guy who did an LS swap auto to auto and he had to replace the entire in-car harness with that from an Integra to make it run (it wasn't fun). Since your Civic is an EK ('96-'00) you probably wont' even have the option (the wiring harness is much different that the EG and DC chassis). As westcoaststyle posted above, you'd also be hard pressed to find a computer to run your new engine. Even a B16A/auto computer would have an 8000 rpm redline and hurt your performance.

Bottom line, if you want to stay an automatic, stick with your D-series engine. If you really want performance, a small turbo system or nitrous setup will help, but I'd say it's just a matter of time before the tranny goes boom. Consistant fluid changes and being careful to not overheat the thing will help but it's not designed to handle a lot of power. If you want to swap over to a manual, that's a different story and probably the best solution (that or selling your car and starting with a manual version) if performance is high on your list.

Oops, I just noticed you have an HX. I really wouldn't considering pushing a lot of power through a CVT tranny, it most likely just can't take it. You might consider a D16Y8 ('96-'00 EX engine) swap and use that automatic. I don't know what's involved with that swap specifically, but probably wouldn't be too bad. Get a much more efficent VTEC system and extra 12hp right out of the box, and far more potential but honestly, I'd consider starting with another base car.

 

yeah I would swap to a EX motor because I was afraid that I can't do the high performance engines and keep the same tranny or else I would have to do the whole thing over again and that would cost to much. How much would it cost to do a tranny conversion?? but thanx for your advice, i will take up on the EX motor and do more to that.
