EF Civic Sedan B18B swap, PARTS you NEED!

[@DJV94022]

For those who go obd0 to obd1 ebay ecu jumper the $20 ones..those are coming out with mixed wires at that harness and missing alternator wire..so it will make your car shut off...i highly suggest to get the 80 dollar jumper harness or blox which is around there too.if you go the 20 dollar route be prepared to depin and repin.plus once you dipin those putting the wire will.be a loose connection so youll have to use hot glue to make a solid connection

My best friend of over 20 years unfortunately took his own life back in 2017. He owned a 1990 Honda Civic Si EF Hatch. Because of him passing away, I reached out to his family and ended up buying his car. I'd already driven his car several times and I've always been a fan of Honda's and the import scene. I used to have a couple badass 4th Generation Preludes back in the late 90s! With that said, his dream was to have a White EF Hatch with a K20 swap. The hatch is indeed white, and in great shape, but no K20! Just the stock D16 engine with 140k original miles. I got the car a month after he passed away in 17'. I've had it now for nearly 6 years just parked out in my garage. My daily is an Audi S4 but I keep that outside in the elements and keep my EF Hatch covered up in the garage to keep it in the best shape as possible. Especially since the car is so damn sentimental with me! Sorry for the long rant, just wanted to share my story and my love for the EF Hatch and how I came about getting the one I own. Yes this info has been covered a million times already on Google, but for people like me that are clueless on how to work on cars, having it banged into our heads over and over and over again is definitely helpful! +1 Sub!

[@Mista808]

I'd love to swap a K20 into it, but unless I meet someone who has experience swapping engines in and out of old Hondas, I'll most likely end up going with the B16 VTec that redlines at 8200rpm that came out of the 94 Del Sols. Of course they were also in the JDM EF Hatches as well! Not as beefy as the K20, but from the research I've done, MUCH CHEAPER and MUCH easier to swap! The car again has been garage kept for the last 5 years, but that'll be changing in the near future. I'm finally getting a list together and as Rafiki from the Lion King said... *IT IS TIME!*

[@Knownworldwide]

Well considering you have an SI hatch already, just buy the mounts to swap in the K20. If you have had it this long, do it right and get the K20 in there. Take your time. Build it how you want it and how you friend (RIP) would like it. Too bad you don’t live closer, I would gladly put it together for you.

I don’t understand where I went wrong with my swap.

I threw on the driver side mount first… maybe thats my issue? B18a1 from a da9 integra using da innovative mounts

You should be using swap mounts for the EF chassis. Can’t use DA mounts on the EF chassis.

Just throwing more info out but the OB2B doesn't always use an immobilizer. I had a 01 Integra and had just a regular key. So I don't know if the immobilizer is chip key based or not.

[@Knownworldwide]

Should be inside the head of the key. Most of them are within the black portion of the key. Of course by now who knows what previous owners (multiple) have done to the car’s electronics by now.

[@aaronhoward7226]

@@Knownworldwide As confusing as it is, it was not. When I first got it only had one key and just got a regular one cut from the original for a couple bucks. I used that key till I got rid or the car, actually still have the original lol. I mean it's possible that it was modified but seems unlikely since it was stock and still had a B18B1. Although my car never had the unlock fob, the person I got it from said in order to get it he would have had to take it to the dealer and etc. So maybe it's only if the immobilizer gets activated it works?

Hey, thanks for taking the time to watch! As stated in the video, you can use any B-series axles and a manual transmission intermediate shaft. If you use the intermediate shaft from a 90-93 Integra, you need to use 90-93 Integra axles. If you use an intermediate shaft from a 94-01 Integra, you need to use 94-01 Integra axles.

I had swapped DA hubs on my STD EF a few years ago. I am due to replace my front brake lines due to cracking. I can't remember if I used stock front brakes lines or used DA brake lines. Would you happen to know which lines I would need?

[@Knownworldwide]

Hey thanks for watching the video! You have a B series in your civic as well? If I recall, I believe DA or CRX si brake lines would work. Might be within your best interest to take the line off and match it up locally at a parts store. You can ask to see a CRX or DA line. I’m 90% sure DC brake lines fit as well. However I would like to think you naturally would have went with a DA or CRX line.

[@liamkelly4478]

Hey mate I’m doing a b16 swap into my EF2. I’ve managed to find a full ef9 running gear swap. I’ve been told that it’ll sit to high in my engine bay and I’ll need to use a d series alternator which is fine. Do you know how much taller it will be, can I cut my hood and use hood spacers to make room? I’m using factory ef9 engine mounts

[@Knownworldwide]

@@liamkelly4478 Hey! Thanks for watching! Hood clearance is more or less a thing of the past. This was back when motor mounts weren’t as good as they could have been back in the day. People using eBay mounts/cheap mounts we’re having hood clearance problems. My engine (B18) fits just fit without any hood modifications or spacers. You shouldn’t have any issues IF you use aftermarket B-series mounts from a reputable company. You could potentially have issues IF using the factory mounts from the donor car. B16 engines are shorter than B18 motors so you honestly need to just sit the engine in the car and find out if using the stock mounts (EF9 I assume?) B-series alternator can clear but you will need to take a hammer to the frame rail in order to make some room. You can try and source a DA9 (90-93 Integra) complete alternator and bracket and that might get you a little more clearance back there but you’ll still likely have to bash the frame rail in slightly. Another thing to note (seems like you might live across the pond) if you find that you have clearance issues, you could. 1. Use spacers (cheapest way) 2. Find a ZC hood 3. Sir front end conversion

[@liamkelly4478]

@ thanks for the quick response, I’m trying to avoid hitting my frame rail in since I’ve just painted my engine bay. I have been told to use d alternator to avoid the clearance issue (I’ll experiment when the motors in) I did try to fit the motor in the car lastnight but couldn’t get the gear box to clear past the gearbox body mount. I’m using a ys1 lsd which I thought was the best fit as the casing is smaller than the hydros. I’ll have another crack at it tonight but yes if I can get it in I might be able to try the si hood or some hood spacers. Sir front would be nice but I’d probably be best just to wait the 2months for hasport mounts to get delivered. Thank you for your help 🙏

[@Knownworldwide]

@ The problem with the d-series alternator AFAIK is only one bolt will mount up so you only will have one bolt holding on your alternator. As far as the back mount is concerned. It’s definitely easiest to mount the bracket into the car first and tighten up the bolt that goes to the subframe mount. Then shoehorn the motor in there and line up the bracket to the transmission. YS1 is no smaller than a hydro transmission as USDM “RS/LS/GS” Integras also have YS1 hydro transmissions. You can swap all gear sets and diffs between the two cases. Also quite sure the USDM Si hoods are the same as any other crx/NON-Si hood so not sure you’ll be gaining any extra room there. You might look into the DA (90-93) Integra alternator and bracket. They are slightly smaller than the 94+ integra setup. But there is some work involved. You would also need the DA power steering line.

[@joshserna9398]

So the b 20 would work with the same parts u showed

[@Knownworldwide]

Yes. However I suggest using a B18B intake manifold since the B20 intake manifolds are very tall. Might not clear the hood without running spacers on the hood hinges.

Quick question, on your shift linkage does the bolt holes for the shifter line up perfectly? Mine seems to be offset and haven't heard back from innovative after multiple inquiries. I either have to find someone to weld one of the holes shut so I can drill a new hole.

[@Knownworldwide]

Which hole are you referring to?

[@marcozuniga8163]

@@Knownworldwide where the shifter bolts up to the shift linkage opposite side of the bar with the joint.

[@Knownworldwide]

@@marcozuniga8163 I didn’t have any problems getting mine in. I mean it wasn’t exactly a walk in the park but it wasn’t hard. There is a bushing on the bottom of that shift lever that may need to be persuaded to line up with the hole. I will say that my bolt was definitely tight in there and there wasn’t any slack or looseness at all.

[@rauelramos2212]

So with this conversion the driver side mount should come with a thick billet looking spacer, did u out that on the driver side or passenger side? Im having this issue to and i may of figured it out, my linkage is tilted to the left towards driver and at first my buddy was having issues with the mounts without the spacer, so he put it on the passenger side and it corrected it but it was wrong, its supposed to go on driver side

Hi, not sure if you have been following along on this build but I haven’t gotten that far as of yet.

@ I see. I am not super familiar with that chassis. Obviously you’ll need the proper mounts for that car. I believe some of those (if not all of them) already were running sequential fuel injection (4 injectors) and if so, it would be to your benefit to find the wiring diagram for your specific ECU (your factory accord ECU) and rewire your current harness to use on the B series.
