I looked around on the pinned threads and didn't see anything that was swapping a newer Integra motor into an older I have a list of everything that I have so far and am just curious what can be reused from my car and what needs to be used from the Integra
Was also doing some digging around and saw that both are obd2B so just wanted to make sure that means that everything should be plug and play from what i have read just might have to make some wires longer to reach
Here the list of stuff that I currently have for the swap(Both are Manual) -Bare LS Long Block From 01 Integra(Basing off the VIN)
-LS Trans
-Integra Shift Linkage
-Integra Axels & Half Shaft
-Integra Alternator
-Integra Intake
-Integra Exhaust manifold
-All New Mounts For EK to Fit Integra(Motor and Trans)
IF SOMEONE HAS ALREADY MADE A THREAD ON THIS I WILL GLADLY TAKE THE LINK
An '01 Integra engine is actually 1:1 same gen as your 00 Civic, so this is the easiest option to swap in.
You can recycle your Civic mounts but it's good (easiest) to do new ones while you're in there. You need a wire harness, Most ideal for your setup would be a 99-01 CR-V (PHK) manual one, it's 100% plug & play to your car. Any intake intended for a 99-00 Civic Si (B16) will work.
Guessing the ECU my car has won’t work ? So do I just need an LS OBD2B Manual ECU? Also wondering do I need to use a different harness or can I use my harness and just extend what needs to be extended ?
37820-P75-A05 is the ecu you need if you want to keep the engine 100% stock and are willing to wire in the secondary oxygen sensor and a couple of other things. The immobilizer board in the ecu will also need to be replaced with a dummy, or you can wire in all of the immo stuff from your donor Integra. (Obviously, the former is much easier than the latter).
Most people just use a jumper harness and convert to an OBD1 ecu. If you aren't going to leave the engine 100% stock (aside from maybe an intake and exhaust) and/or don't have to deal with emissions in your state, this is the easiest option. You also won't have to worry about the secondary oxygen sensor. Buy a good
You can make the D16Y7 harness work. You'll have to convert the three-wire connector to two-wire (trivial) and add a knock sensor wire, then stretch it all round to 'make' it fit since the Y7 has a totally different intake manifold setup. You'll also have to extend the IAT wiring over to the sensor that's now on the manifold instead of the intake tube. Secondary oxygen sensor wiring can either be extended back to the cat from the transmission housing (pre-made extenders are on eBay for <$20) or run it from the ecu 'A' connector across the dash and out the tunnel like factory (this is the better way).
The PHK harness is 100% plug and play with B18Bs or B20Zs. You would still need run the secondary oxygen sensor wiring through the cabin to the rear of the cat though (if using an OBD2B ecu).
So I’m going to try and get the car BARD in California which means the car had to be basicly had to look like that motor belongs like all emissions stuff has to be the same as the Integra all the vacuum lines ect, so I’m wondering what ecu would be the easiest to make work I would rather just have an Integra ecu with a jumper to the chasis harness if that’s a thing and just run a crv harness like you mentioned would that work or did I just miss everything you had said before
Gotcha. I just went through the BAR process with a B20Z in an LX (effectively the same swap) so can confirm, you'll need the ecu I listed above and you'll need to make sure you have all of the right emissions stuff on board.
Ok, I just want to clarify tho would an OBD2B Integra manual ecu work for the swap ? As my car is currently obd2B so I don’t see a need to go back to obd1a if I don’t have to just to simplify the whole process and the sensors I need to wire in do they just connect from the main harness or do they need to go from the chasis harness to the engine harness
Yes. It has to be a 00-01 ecu, which is obd2b. I gave you the exact part number that you need above.
the O2 sensor wiring will go into ecu A, which is on the chassis harness. The knock sensor will need to run through the engine harness.
You may also have to rewire the CKF sensor down by the crankshaft (if you repurpose your Y7 harness). I can’t remember which engines had the three wire sensor, but the b18b is definitely a two wire sensor.
So I know people have said I can just use my stock harness for the engine is it just easier to not use that and just go to the junkyard and pull the engine harness off a a crv/Integra like you said then so I don’t have to cut up a good harness and then from there would I only have to wire in the O2 sensor, and then the knock sensor ? And just trying to clarify sorry if im going rounds over the same thing just don’t want to mess it up so the O2 sensor from the engine harness from the Integra/crv will plug into the sensor just has to be modified from where it plugs into the Ecu
Ok so I did some looking around on eBay and this is what I’ve found so far for a harness and ecu just walked to double check that all of it would work for what I need before I buy it Guessing this one wouldn’t be ideal to buy since it says it needs a tune basicly
That’s a pretty good price for that harness. I was going to offer you one that I have but I want 50% more than that for it lol.
you need to remove the immobilizer board from the ecu and replace it with the Doctronic immo board. Otherwise you have to install all of the immobilizer crap from the Integra into the car and have it programmed. So not tuning.
So that harness should work along with the ECU I sent correct ? And does the ECU need to be flashed with a stock tune or should it come that way ? All I know is that California is super **** about tunes currently
It’s got nothing to do with the cal. Just pairing the ecu to a key.
These old ecus are not tunable or writable except for the immobilizer. They also don’t report any cal ID, CVNs, or VIN info so the state really can’t tell anyway. I actually bar’d mine with a CRV ecu board inside of a P75 case because it seemed to fix a strange issue that I was having. Not legit at all but I figured out that they oils be none the wiser due to the lack of info from the ecu.
I just picked up a ecu for the car and a 00 crv manual harness and I’m looking at the plugs for the ecu and 2 of them work but the green connector is significantly smaller is there something I did wrong or was I sent the wrong part possibly
