Buddy is buying a 1996 Integra parts car, and is planning on swapping the B18b out of it and into an 2000 EK hatch.

Details:
-Integra is 1996 (OBD2a) B18b
-Civic is 2000 (OBD2b) has a D16 in it right now

Question: Does having this Integra give us EVERYTHING we need to swap it over to the Civic? I know one is OBD2a and the other is b.. can we just use the b18b harness all the way back through the firewall and to the ECU and not have to buy a obd2b - 2a conversion harness?

ANY help or input on this swap is appreciated, thanks

Use the mounts that are already in your ek everything is good to use from the teg, you will need the 99-00 si rear t bracket, Im not to sure with the harness so someone else will have to answer that for you lol

shaylude01

Thanks for the reply. Why do you need the rear T-bracket? Wont the One in the Teg work?

itsnotfast

You'll need the rear T bracket (the one from the Integra wont work) as well as the driver side mount bracket from a 99-00 SI. You can just use your stock wiring harness in your car. You may need to extend some wires. You'll need to get a OBD2B LS ECU and distributor or convert your car (with an ECU conversion harness) down to OBD2A and use the Integra ECU and distributor. You'll need the B series linkage, axles, and intermediate shaft from the Integra for your hatch.

could we not use ls engine harness run it though firewall straight to the integra ecu?

itsnotfast

No, it wont work. You would still have to adapt the harness in the car to mate to the Integra ECU and that would be quite the rats nest of wires. The ways I explained is the easiest and the best way of doing it.

If you plan on further upgrading down the road you would want to convert it all to OBD1 but this will cause problems with inspection if your state plugs into the car. For now the way I explained is the easiet way to go.

shitty deal i might have to order obd2b to obd2a conversion thing

itsnotfast

They're not too bad. Check out eBay, you can get one for like $40-$50. Keep an eye on where its shipping from. I made that mistake before. It shipped from hong kong and took like a month and a half. You may even be able to find on in the marketplace cheaper.

I still just dont understand why you couldnt just use all the Integra stuff.

Like this:
B18b integra engine - B18b integra engine harness - Then, take the part that the engine harness goes to and runs through the firewall to the ECU out of the integra, transfer it into the Civic - Plug that into integra ECU inside civic.

Doing that your running it the EXACT same as if the whole system was in the Integra, but just in a different car

Integra engine harness - Integra firewall harness - Integra ECU.

u know where i can find a rear t bracket cant seem to find one.

bold= dont need

ek4_b16a

can't do this because of obd2b harness won't plug up to obd2a interior harness. your cluster and all won't work. you're best bet is to do what itsnotfast stated. that is the easiest and workable way you can do. you can get the rear T bracket from the dealer. it's not too much or you can order from majestic honda

I think people are missing the part of the question where the OP wants to know if he can use the engine AND interior harnesses from the Integra. Everyone keeps telling him the interior harness won't match up.

92lxsleeper

double post but whatev.....

dont just swap the b18b into the civic. it only nets you maybe 10 more HP, more weight and a just as shitty gear ratios.

build the motor up. either boost it, or throw some p30 pistons in it with a vtec head. at the least you are gonna want to swap out the rod bolts for ARP;s and i have a set i bought that i dont need. if u want them pm me. $30 shipped BRAND NEW IN PACKAGE

MrFresh

Engine will swap just fine. Use all motor mounts, you need an 99-00 Civic SI Rear bracket because you have a Civic... Not an integra. Secondly, the wiring harness from the civic is an obd2b harness, you can use that harness it bolts up to your motor (doesn't matter if it's auto or manual/same ****). May have to change Ecu... but probaly not. Easy swap should be done in a few hours.

Cheers.

thanks ill have to run integra ecu due to i got sohc in it right now so it wouldnt run the dohc to good. but thanks alot for info man

SloHa+ch

why wouldnt i swap a b18b into my civic ur telling me its gonna be barly faster with b18b over a shitty d16y7?

b18b-142 @ 6300 RPM
127 @ 5200 RPM

d16y7-106 @ 6200
103 @ 4600

i see 36hp gain & 24tq

(temp motor till summer when i buy b18c to build and boost)

HondaPartsHero

I think he's assuming you have the D16Y8 which is 130HP. The B18 will be night and day compared to the Y7.

SloHa+ch

that would make sense than

Question:

Is the only difference between obd2a and obd2b the plugs for the Dizzy?

Heres how im thinking we'll do this swap:
we'll get an obd2b Integra ecu, then we'll use the stock harness thats in the car, and get an obd2b Dizzy. Yay or Nay?

94EG8

As far as the integra goes OBD2A and OBD2B distributor plugs are the same. It's only the '99 - '00 Civic CX/DX/LX/EX that are different ('99 - '00 HX/Si use the large style distributor plug) Either way you look at it you'll need to swap the distributor plug, use a conversion harness for the distributor, or swap the D-series CYP/CKP/TDC sensors into the B-series distributor housing. You'll have to keep the Civic harness and modify it. You'll quickly see why you can't use an Integra harness if you try it, they're just flat out completely different.

Like I said up above Integra distributors are the same, OBD2A or OBD2B. Also all OBD2B Integra ECUs have an immobilizer that has to be removed and replaced with a dummy unit (you also have to repin the fuel pump wire from A16 to A15 or it wont start), or use a conversion harness and the OBD2A ECU.

^Thanks for the reply I did not know that, that makes a lot of sense.


Heres kindof a Far off question. But, lets say we went to a junkyard and bought an interior harness from a 96-98 civic, which would be obd2a (which is what the civic is), would that be a smart idea? Then we've got all the car wiring obd2a, complete. Is it hard to swap the interior wiring harness???

ek4_b16a

again, that would not work because the wires are different from obd2a to obd2b. your speedo will not work and a few other things. you are best off just using your stock harness.

94EG8

No, you're still in a huge mess. '96 - '00 Civics have a completely different type of harness setup altogether, it's not even kind of the same. Integra and '92 - '95 Civic are a 2 piece design. '96 - '00 Civics use a 1 piece design.

I don't think hard is necessarily the right word, but it's sure as hell time consuming. You basically have to gut the car, dash, heatercore, pedals etc.

I understand it could be done but what would be the purpose of pulling the dash and converting everthing under the dash to a different harness when they have jumper harnesses for <$50. Btw you don't have to swap distributors when doing the swap. The only parts you will need to complete the swap is the t bracket, the drivers side "post mount" as its called, obd2b to obd2a jumper, if you want to keep ac you will need a crv or del sol vtec ac bracket, if no ac then the integra bracket will work. The civic harness will be used. You will only be able to use the integra harness for parts.
