Ok first off I am very new to this.
Second, I want to swap a H22a into my 96 civic lx that has automatic transmission.From what i've read I need a p28 ecu.The proablem comes with me trying to find even
A basemapped p28 with automatic transmission.
I have searched freakin everywhere and cannot
seem to find one. ANY help would be huge.

T.N.

There more than that to an H22 swap i don't even think they have H2B kits for auto's(correct me if im wrong). H2B as it's a real pain to hack for the shift linkage look that up OP. b series is a LOT easier do you have the h22 or yet to go and buy it. Im also pretty sure you'll need to do an auto to manual on you'r civic you need to research a lot more.

Don't think it's going to happen. NEVER heard of such a swap being done.

Variable88

Well my car was automatic when I got
it so I wanted to keep it that way figuring
that it would be easier. Now that I've dug and dug on info
to do the swap it seems an auto H22 isn't gonna happen.
I figured I would ask if anyone had done this with any success. I know there is more to the swap than just boom drop in a motor and a new ecu then drive away. Like I said above I assumed early on that staying auto would be easier.

B_Swapped93

Grumble is right i've never seen or heard of it being done. If you're really set on a H22 then you'd need to go H2B which would involve auto to manual.

You assumed wrong. Auto H22 swap in that chassis will not happen, beyond all the wiring issues there clearance just isn't there. That said there's very little extra involved in swapping to a manual when you're doing an engine swap anyway, especially in a '96 - '00.

a 96-00 ek can not even fit a b series auto in it without cutting the subframe. as the h-b kit spaces the trans out even farther this would make it nearly impossible. its all a dream. you would never get the auto to work as running a h22 ecu will have diff sensors on the trans then the b18 auto. running a b18 auto ecu would not be recomended for this swap as the h22 would run lean most likely. Maybe if u ran a Apexi AVCR ( to controll fuel,timing)on a b18 auto ecu but it would still need a tune and something to control vtec crossover.. this is probably the only way to run it on a obd2 computer to pass emissions. this is ONLY if you can get the wiring and Trans to fit and work properly! If you wanna try it you would be on your own as no one else has done this to help you out....Goodluck

Variable88

Thanks for all the input guys. I think my best bet is to sell it and
get something with more options to swap with.

94EG8

That part actually can be done, sorta, but it's much easier in an Integra. It works like this, you run a '94 - '95 automatic P75 LS ECU, these use a separate TCM that connects to the 4th plug of the ECU. Chip the ECU and tune it and run an H22 TCM. In a civic you need to wire the TCM though which is a good 40 wires or more. The frame clearance issue however remains.

There's not really anything wrong with the chassis, nor will you found many other Honda chassis that are that swap friendly, you just won't be keeping the automatic in it is all.

Variable88

What about just saving for like a b18c type r then cutting
the middle out and fitting a shifter and then clutch pedal
by the break pedal.Would anything else extra be involved? I'd like to keep the ek chassis. I've heard b swaps ARE easier. Seem to be more expensive though.

B_Swapped93

There is NO NEED to "HACK JOB" a b-series swap do an auto to manual swap the drop the B in

94EG8

You just swap out the whole pedal set clutch, brake and gas, the holes are already there, it just bolts in, the same with the shifter, the hole is there.

Chris Ward

yes infact you can run a b18 b20 h22 auto or manual in a ek 96 to 2000 but youd need the right ecu like p28 with jumper harness also in an eg too without cutting the frame

Please show proof of an auto h22 in a civic. 23:59:00 remains.

Caoboy

Don't be daft.

If it can be done in a Prelude it can be done in a Civic.

tony_2018

Still no proof, clock tickin.

Caoboy

I just gave proof. It's in a Prelude!

JRCivic1

It probably CAN be done, but certainly not by a newbie like the OP. This will be a challenging swap... the wiring to begin with will be extensive since auto Civics have the transmission control inside the ECU and Accords and Preludes have a separate transmission control box. OBD-1 Civic P28 ECU's didn't utilize electronic shift control... they used a mechanical cable. IIRC, all Accord and Prelude transmissions from 1990 and up have electronic control (for sure the '94+, not 100% on the '90-93) so the TCU will have to be integrated.

It just seems like a lot of work... and there is little info online to guide you... so the OP would have to be very comfortable with wiring as well as the normal mechanical modifications that will be necessary to install the Auto H22A system. Also, I don't think any aftermarket company makes an EG H22 auto transmission conversion mount... and these will even differ depending on the model year of the Accord/Prelude transmission.

Even manual H22 complete swap conversions in an EG typically require slight frame rail modifications... mine did with the Place Racing mounts I used in '02 when I initially did the swap. The auto transmissions are dimensionally larger than the manuals on the transmission case end, so I wouldn't be surprised if right side frame rail modification will be necessary.

Then again... this thread died six years ago and no progress was ever reported by the OP. I say we put it back in the ground.

Caoboy

Agreed.

It'd be best to have both cars available, in perfect running condition, and by the time one decides to swap engines, they'll probably end up deciding to just sell the civic and drive the Prelude

The hole is there? Must be different on a 2000 EK. I had to cut away the chunnel for the auto shifter cable, section the tunnel, and fab a plate for the B shifter linkage.

tony_2018

i got lucky, my sedan had the opening. my cousin hb had it too.

Freedo_Civegra

The CMC opening was there, but that was it. No shifter hole opening. I had the auto brake pedal in for a little while after the swap. That clutch pedal sat WAY to close to that thing. I remember trying to downshift and accidentally hitting the brake with the same foot almost every time. Drove it like that about 2 weeks.

tony_2018

oh, the shifter hole for the auto cable hole. Yeah I drilled out the spot welds for that one. Easy cheesy weezy sleezy. Yes the hole through the floor for the actual shifter was there.
