Hello everyone, I'm from Ireland and below are the pics of my car.
i have finally got my hands on my first ef civic. I've wanted one for 10 years so I'm delighted to get a rust-free 1991 ef civic with only 70000 miles.
The downside is its a 1.3 carburated engine with a choke. Despite having folders of information I've collected from trawling through the internet researching the ef civic (and b16/b18/k20 conversions) I managed to miss the issue I've taken on with the dpfi to mpfi conversion.

I've previously owned a Milano red k20 ep3 which I loved. It had 43000 miles and I sold it for 2500 euro/ 2800 dollars during the economic downturn.
Every day I feel like smashing myself in the head with a hammer for selling that beauty of a vehicle for that price

Unfortunately, I'm not mechanically savvy and I have no access to a lift but I do have a great mechanic whos an enthusiast and has himself had plenty of hondas.
First things thing I did when I got the car was undercoat and seal it, then buy the maxspeedingrods shocks but I haven't yet found the wheels.
Ultimately I want to put a b16 into it, but right now the carburater is shot and the car is undrivable.
As far as the engine swap my mechanic has said I should buy a full donor car BUT in Ireland & The UK these cars are if your lucky 4000 euro / 4500 dollars. So unless you get really lucky and find a wrote off/smashed Integra/type r I really don't think his advice is the way to go. What would you guys think?

I've also enquired about turn-key ignition swaps with 2 Leading honda specialist in this part of the world and we are talking north of 5800 dollars and north north of 9000 dollars which was the second quote.

I've added myself into ef civic/crx facebook part groups so I can find parts such as used hasport mounts, b series axles etc for way cheaper than RRP. I'm going to eventually create a thread possibly including links I've pulled etc because if I'm honest there's just so much! I need help.

Looking forward to speaking to everyone.

Cheers
There she blows

 

Looks like a nice, clean and straight car, good find. Can you finish the MPFI swap to get it going for now until you swap it?

 

Thanks! Ye, I'm happy with it. I havent started the mpfi conversion as Im still so confused about it all.
Noob post, but I don't know the exact parts needed and If I can get a manifold that can fit both this 1.3 engine and the eventual b16. I assume you cant as one is a sports engine and one is a lawnmower.
Right now I'm just trying to gather the part list I need to do the MPFI swap. I've spent the night looking at wiring the harness to an obd1 dizzy and then the premade adapter harnesses.
I'm going to remove the carb and try get the car driveable while I gather the stuff needed for the MPFI swap.

Would you advise buying a 92-95 efi donor car to do this?

thanks

 

There's lots of info out there on Dual point to MPFI, but Ive never seen it done from carb to MPFI. I'm sure its possible, just need to figure out what parts you need (Im guessing same parts for a traditional MPFI swap, distributor, applicable wiring, intake with TB and injectors, etc.., and an MPFI capable ECU). Speaking of ECU's, does your car even have one, being carb'd and all? If not, then yes, you may very well want to get a donor car, because you may not have a traditional cabin/under dash wiring harness with ECU plugs, which you could easily source from a parts car.

Or....and I'm thinking out loud here, just to get it running, you might be able to look into a stand alone TBI fuel injection set up, kind of like the muscle car guys run when removing the factory carbs for EFI (like a fitech system).

 

Unless you build a custom harness, you're at least going to need an engine harness and firewall/under-dash harness to do the swap - basically the harnesses that let everything in the engine bay talk to everything under/in the dash. If you can find a wrecked donor car for cheap, that may be the easiest solution. Otherwise, you could always figure out what you need and see if you can pay someone in the US to pull it from a junk yard and ship it to you. You'd also have to run wires to the fuel pump, and swap tanks for a fuel injected tank and run new lines. If you convert the D-series that's in there now to fuel injection, you won't be able to re-use the manifold on a B-series. I have seen a few folks recently talking about wanting to swap a carb'd Civic to fuel injection but haven't seen a writeup on it yet.

 

Not worth going EFI before swapping in the b16. Get the motor you want and work on getting that running.

You'll also need an EFI fuel tank. Easiest route is to get a rywire harness for the motor you've got, and then splice in the few wires to the cabin harness you need.

 

How many miles?
Those quotes. Which* b16 did you have them quote you for? carb = old.5 b16 turnkey = new harness x everything = people suggesting doner cars 🚗
Best advice imo of course is sell it/if you want to drive the car within a year. keep the carbs and find yourself someone that can rebuild it and tune it for you and most off all help with further diagnosis. With a fresh battery see how that treats you/still sell it because lol / where do you live? There are no z6 or y8 swapped running Ef’s in your area that you could have bought???
if your friend hasn’t done at least 2 efi swaps on any Honda I suggest you just buy one. It’s not worth the wait

 

Hi,
so a little update. I've bought a donor car which is a JDM 92' crx del sol B16A (second-gen) the downside is its automatic but the upside is that the engine hasn't been hammered.
I believe the ECU is a P30 that needs "rp18" jumped to change from AUTO to manual.

I've been in contact with rywire who said they can make a custom harness so that's good news! However, this was before I bought the CRX del sol

the other issue is the EFI fuel tank and fuel line/wiring swap. When driving the del sol I can hear the petrol swilling around behind me so I assume this tank won't fit into my ef?

Can anyone link me a write up on the EFI fuel tank fuel pump/ fuel line/ wiring, please?

I think for gearbox/transmission I'm going to go S4C with an LSD. one has popped up with a carbon Syncro rebuild.
Can anyone advise as to what to look out for when inspecting these gearboxes/transmissions?

BTW I won't be selling the EF car, they are ultra-rare here and I have the patience to wait and build the car slowly!

Thanks, everyone, I'm in it for the long haul!
