I am planning on swapping a B16A2 in to my EK hatch as far as obd1 b16a2 into a ob2 chassis and I cannot seem to find all the complete accurate info and looking to compile all swap info.

I tried to search for the swap info and here is what I found out:

But B16A2, 5-speed, axles, ecu, shift linkage

99-00 si trans mount

Del Sol A/C bracket to run A/C

Conversion P28 connector which is plug and play, which means I shouldn't need any other wiring issues

what about things like throttle cable

or any other odds and ends

thanks a ton!!!!!!!!!!!

 

If you run an OBD1 B16A in an EK civic, this is what you'll need.

Mounts/axles/shift linkage:
A 99 Si and 94-01 integra (any model) is your friend for this swap btw.

- 99 Si rear engine bracket
- reuse your existing SOHC driver side mount & dual-post bridge bracket
- If the OBD1 B16A comes with the front tranny bracket, use it. If not, you'll need one from a 99 Si or 94-01 integra.
- reuse your existing SOHC TOP tranny bracket & mount on the OBD1 B16A. you won't be able to reuse the OBD1 B16A top tranny mount as it is designed soley for an EG/DC2 chassis.
- If the OBD1 B16A comes with a complete shift linkage, USE IT. IF not, you'll need one from a 99 Si or 94-01 integra.
- Reuse the OBD1 B16A axles if it comes with a set, totally compatible with your EK chassis. Make sure it has the half-shaft too. If no axles come with the motor, guess what? you'll need a set from a 99 Si or 94-01 integra or even from any other JDM 92+ B-series engine.

Wiring & ECU:

Wiring can be a slight hassle when tossing an OBD1 motor into an OBD2 vehicle; because OBD1 and OBD2 engines use different style connector plugs for the distributor, injectors, alternator, and IAT sensor.

You HAVE to use an EK engine wire harness for your swap period. Because EK's use a 1-piece wire harness design unlike Integra's and EG's which use a 2-piece wire harness. You can either reuse your existing engine harness or use one from a 96-00 EX or 99 Si depending on what year your EK is. If you have a 96-98 civic, using a 99 Si engine wire harness is out of the question because of slight changes between OBD2a & OBD2b wire harnesses; you'll have to use a 96-98 EX engine wire harness.

The reason I'm suggesting an EX or Si wire harnes is because these harnesses are already pre-wired for VTEC, 2-wire IACV, and knock sensor. When you use a CX/DX/LX engine wire harness you have to add the wiring the EX harnesses already have and you'll essentially be manuall converting your non-VTEC engine wire harness to an EX/Si engine harness. You'll have to manually wire in VTEC, add the knock sensor wiring (unless you run a reprogrammed P28 which deletes the knock sensor), and perform the 3-wire to 2-wire IACV mod.

On top of this, being that the B16 motor is OBD1 spec, you'll have to perform some further wiring by changing out the EK wiring distributor, alternator, and injector plugs to that of OBD1 plugs. Or you could try and source out an OBD2 B-series VTEC distributor, injectors, and alternator...then you won't have to cut & splice over to OBD1 plugs.

Reading that you want to convert to OBD1 P28 ECU via jumper harness is a smart move. This will save you a little bit of heartache as far as extra sensors you will not have to worry about. ie. the 2nd 02 and CKF sensors.

It would help to know what year your EK is.....

Other than that, that's all you need to do...

sorry for the wordiness...

yesh...
My other life can get in the way of Honda tech support life

 

That is a flippin awesome write up.

Thanks a ton!

Just on question, can I use wiring conversion components from Rywire.com for all the wiring issues?

What about the guage cluster do I need to get a new cluster and what about getting a tack signal when I put in a new cluster. What should I get EX or SI cluster.

You don't have to do any wiring ot the cluster; just plug n' play an EX/Si cluster depending on what year your EK is.

Yes, Rywire's products should help in the distributor area...

 

So I don't have to have a si or ex cluster to have working guages?

Is it only on gsr, prelude, the bigger engines have to have a bigger fuel pump?

With the stock b16 manifold hook up to my factory DX exhaust, at least till I get some more money?

Is the HASPORT wire harness conversion worth $300 or do you think that it can be done easily by cutting, splicing into a EX wire harness. Because all I would have to do is buy the conversion harness from chassis to engine harness, right.

I may have screwed myself though, I live in NC and we have emissions testing and I don't know what is going to happed when they plug into the OBD2 chassis and get readings from an OBD1 engine. Oh well I will have to worry about that next year.

Sorry for any headaches I will be giving you but I just want to make sure that I can do this in one weekend. I hope that I am not forgetting anything.

that is correct

not necessarily. Your civic pump will be enough fuel pressure for a B-series engine and H-series engine. Integra/civic and I think preludes all share the same fuel pump PSI specs.

With the stock b16 manifold hook up to my factory DX exhaust, at least till I get some more money?

No it won't because the cat on a 96-00 DX is on the actual upper portion of the exhaust manifold and not down below where the collector is.

Is the HASPORT wire harness conversion worth $300 or do you think that it can be done easily by cutting, splicing into a EX wire harness. Because all I would have to do is buy the conversion harness from chassis to engine harness, right.

I actually have never seen a Hasport harness for a B-series swap, so I can't comment on that. My original suggestion is to either reuse your existing DX wire harness and modify it as mentioned, or find an EX wire harness (can be found used for under $200) and use it with minimal wiring mods.

I may have screwed myself though, I live in NC and we have emissions testing and I don't know what is going to happed when they plug into the OBD2 chassis and get readings from an OBD1 engine. Oh well I will have to worry about that next year.

Well, there are a few tricks you can do to pass emissions, but you can ask those questions next year
