Hello again everyone! A friend and I want to swap a B16a2 into his 2000 Civic ex coupe. and I only have a few questions. I know we will need the motor mounts (probably go with Hasport) obviously and the complete engine with intake manifold and everything, but besides a transmission and the complete swap, what else would we need? I've seen people talk about swapping into DX's using the same harness as their d16 with a couple of plug modifications, would the EX harness be able to be used in this same manner? If so, How? Also, would the engine drop right in? I've seen and heard from some people that the engines are slightly larger than the bay and the bay needs to be ground a little bit for it to fit right, and others say it will fit fine. Any input would be greatly appreciated. Thanks!

If your not able to find a straight harness adapter, then you would need to get the wiring diagrams for the B16 and EX and repin the plugs so the wiring all lines up.

It should fit without grinding the bay. It's not uncommon for there to be conflicting info on how well swaps will fit, but if some say it fits fine then it fits. The people who had trouble were probably inexperienced and doing it in their back yard.

what do you mean by adapter? i didnt know they made adapters? is it like a second harness that kind of 'piggy backs' with the original and work together? or just plug adapters to make them fit?

I know they make OBD0-OBD1, OBD0-OBD2, and OBD1-OBD2 but, I didn't know they made adapters for the Y8-A2 conversion.

Don't quote me but, I think you can use the A2 harness with the A2 ECU. I believe it should be plug and play.

Check here for additional info, they know more than we do about this: http://www.honda-tech.com/forumdisplay.php?f=1

well because we probably will get a Hondata ECU. so wouldnt i have to modify the harness from my ex to plug into the anyways if im going to use that harness for the B16?

2000 Ex
99-00 B16a2


Is a EASY SWAP, You need the following to make is a PLUG AND PLAY SWAP

Complete motor (B16a2)
Use your Ex harness, You will need to extend the IACV sensor wire and the IAT sensor wire
Use ALL 99-00 SI Mount brackets and hasport or OEM mounts

Also use a 99-00 Si ecu


that is a plus and play set up

so all the plugs should fit directly with no modifications besides extending? sounds pretty sweet. We've also been thinking about a K24 from a RSX-S + 6 Speed transmission, but neither of us have read anything on how that swap goes down. Seems to be more and more common every day but i'm still skeptic on how much parts that involves, im not worried about labor, but really who is? lol.

k24 is big money and a big hassle stick with the b16 or b18 it will be significantly cheaper and will do a good job to add some extra power to your car

its really all not that big of a deal from some reading i have done up on it, however is quite a bit more money like you said with having to buy quite a bit more parts for the conversion. but i most likely will go with a B16. although i am equally interested in both.

?!?
is there such a 2.4 liter RSX?

well, what i referred to was a K24 Block with a K20 RSX-S head. makes for a great and quite powerful engine.
