ls swap in eg
Ok, heres the deal guys, I have a 1993 Honda Civic SI with a bad D16Z6 in it. My buddy just totaled his 1996 Acura Integra LS. I would like to throw his motor, tranny, and A/C into my car. I know this is a very common swap, but I am new to it. I am unsure if his car is the same gen OBD, and I don't know if I'm going to run into problems with swapping in a non VTEC motor. Right now I was planning on taking his engine, tranny, shafts, mounts, shift linkage, exhaust, intake, starter, fuel line, and ECU. Will this engine and ECU simply plug into my harnesses? I just don't want any surprises, and thanks for any info you can throw me.

Re: ls swap in eg (phyle69)
yeah thats a direct drop in and plug and play for your eg.but i am not sure about the ac part..u might need to do some modification to ac.i think u might need to use your existing d series ac setup and get a crv or vtec del sol ac braket and re use your d series ac compressor

Re: ls swap in eg (crazyguy)
I forgot how to retain AC, I forgot if you have to use the AC bracket off a del sol or any 5th gen civic.
@ OP:
Don't listen to the other guy, '96 is OBD-IIa, your 93 civic is OBD-I.
You will run into some "mods" - but no problems. First off, use the injectors off your Z6, they can pump enough fuel for the LS, don't worry, but the plugs won't match since OBD-IIa and OBD-I are diff, so use the Z6 injectors. Neither will the plugs on the distributor and the alternator (match) - so you'll have to use the alternator off your old engine (again, it will work fine) - I'm not sure if you can just rewire the plug on the LS alternator - probably, but I don't know. As for the distributor, cut the end off the LS one & the Z6 one, and wire the plug end off the Z6's distributor onto the LS - this'll make it so your distributor can plug into the engine harness as well - it's just color matching.
Then for the ECU, you'll need either an OBD-I to OBD-IIa conversion harness to run the LS ECU, or you'll need to run a chipped OBD-I ECU running an LS basemap.
The fuel system is the same, you don't need to change the fuel lines going all the way back to the tank/pump, the stock ones are fine, just from the firewall filter on forward.
After that it's pretty much plug 'n play w/ B series mounts.
As far as the exhaust goes - I'm not sure about the interchangeability between DC2's and EG's...but I'm not sure if it'll fit..you're probably better off keeping yours.
You won't run into any problems swapping in a non-VTEC motor, just tape off the VTEC solenoid plug and the VTEC oil pressure plug as they won't be needed - but don't cut them.
Hope that helps some.

Thanks guys. So I can't use his mounts? And where do I find the conversion harness? I have a Greddy full cat back, I'll prolly try to use his manifold and cat. I'm actually not to worried about the ac for now, I go to school for residential ac, i can figure that all out later, plus the car has windows and moonroof. Please keep the info comin.

Ok. B series. Sometimes I'm retarded. What should I do about switching OBD? Where can I get a conversion harness, or an ECU that will work? And do i have to pull all the wires through the firewall in that case?

Do a search for "b18b1" in the 92-00 forum. make it archived. You'll find tons of info on b18b1 swaps.
We also have an index at the top of the forum with all kinds of b18b1 information.

Re: (Syndacate)
correct. 1996+ = 0bd2a
you need to get a p75 ECU. thats a obd1 ls ecu.
using the original harness off the civic, since it has a sunroof, it is an SI so you can use the harness but needs to block of the vtec parts that are not being used. You need a obd1 distributor and obd1 injectors.
ORRRRR
convert everything to obd2. Use an the obd2 ecu from the teggy, get a obd1 to obd2 conversion harness, blah blah blah. list goes on.
my personal recommendation is to stick with OBD1 for tuning sakes. If you ever plan on FI, you made a wise decision sticking with obd1. and Yes the b series axles and mounts are built for 92-95 civics.

If your D16Z has the throttlebody map sensor you can ignore this.
If your car has the firewall map (92s do and some 93s) do a search for 2 map sensors and with the pics(ff-squad) and basic instruction at the bottom will get you through that easily.

don't listen to this guy, the LS harness will plug directly into your civic allowing you to use the obd2 injectors and dizzy . as for the ecu you can get an adapter harness for the ecu out of the 96 teg or get an odb1 P75 or you can get your P28 chipped to LS spec. as for the ac, I don't know if the lines will bolt up or not

At least one guy knows what he's talking about. to you, man.
Dont reuse any of the civic parts.
Use everything from the obd2 integra, except the ecu. All the mounts, shift linkage and axles will bolt right in. The obd2 engine harness will plug directly into your civics main harness.
Then simply plug in an obd1 LS ecu and you are done.
I have done this exact swap more than once.

Re: (e gee two)
If you want AC in your LS swapped EG you will need the LS ac compressor along with a bracket from a CRV or Del Sol. I dont know the years of the cars unfortunately... sorry.

Wrong. Use the stock civic compressor, not the LS compressor. Correct on the CRV or Delsol Vtec bracket, though.

Reread his post.
He is saying you DO NOT need to use the obd1 injectors or distributor. You DO NOT need to swap any plugs.
And he is correct.
You can use the ENTIRE obd2 engine assembly(including obd2 engine harness, injectors, distirbutor, alternator, etc,etc).
The OBD2 integra engine harness plugs DIRECTLY into the civics obd1 main harness.
Then simply plug in an obd1 ECU.
The first time I did this swap was back in like '99. I drove the car for 3 years, then sold the swap to another guy and it is still running in that car today. Zero problems.
Full obd2 engine, obd2 harness, obd2 distributor, obd2 alternator, obd2 injectors, in a '93 civic running off a obd1 LS ecu.
