Is the Aus ED (GL) exact same as the american DX Trim/engine level?

No, I reckon ed gl come with Carbie engine, and all American civics came with FI engine.

Ok, thanks that mainly what i wanted to know, so american forums wont be of much help then when it comes to engine conversions with ED civic's

That depends on what your looking for and what sort of conversion you want to do.

Are you thinking of upgrading or converting to EFI? It's been done here.

Transplanting a B16A - also done here.

Considering it, My D15B4 is mostly dead, I'm not fully familiar with engine swaps and so on, so need the guidance from others and previous build logs to wrap my head around it.

It seems like a good time to carry out a swap, B16 is a little out of my price range, but I've seen a few DOHC ZC going for a fairly low price in the trade section of the OzH forums. This does involve carbs to EFI.

Now I've seen a ton of conversion's done from DX and Si honda's in america. For the wiring they all just say use the existing loom and solder on a couple of extra wires. But I have a feeling that's not the case on carby models.

Which brings me to another question.

Are there any other honda motors that can swap into the Australian Carby ED civic that dont require new ECU and wiring loom? Or is it just the D15b4?

If you are able to find someone parting out a ED9 CRX you can get the fuel tank w/pump, engine, ecu, wiring harness, fuel lines etc to do the conversion. The CRX will provide you will all the parts you need.

Yes you could do the twin cam Non-VTEC. That's one option. Another is like I've done and substitute the D16Y1 SOHC VTEC package.

The twincam is revvy, a good engine but a bit long in the tooth unless you do a complete rebuild. A cheaper option is the Y1 which should have fewer kms on it given it's a younger engine.

You can rewire with the loom from the EG5, modify your existing carby tank (please read all the disclaimers before attempting this) because the CRX one is very hard to find, and use an EK/CRV dash cluster (you're also changing from cable speedo to electronic speedo). Anyway read some of the builds in the Build Thread (markismaximus or Dave_XR8 for examples) for details. Upgraded braking from a DA9 including master cylinder/booster and proportioning valve or go bigger with Prelude VTiR redrilled discs and modified calipers (Type R).

You could try a B18A1 out of a Integra DA9 but see above for best option.

Thank you for the response Peter, So is a D16y1 a B16a but SOHC instead of DOHC?

I do like that option.

Also is the EK/CRV cluster a direct bolt on replacment of the ED?

I have read mark's build from start to finish twice now, will have to find dave's.

One thing I have to watch out for is P plate rules and the no mod plate's. As far as I know I can only swap an engine in that was offered as an option. Not sure if it means worldwide option or only in australia. I remember in marks that it used the stock engine mounts, so because of that he didnt need a mod plate if i recall correctly. I would hope they would allow the installation of a newer honda civic motor to be installed.

I wonder if the D16y1 would get a roadworthy with drum brakes on the rear, or if I would have to install the rear disks. Its an upgrade I would do anyway down the track, but would rather hold it off till after RW and car is on road.

My dream one day would be to do up a B20 Vtec, but have to wait till opens for that. So the D16Y1 would be a good step in between to get the car EFI.

[hmetro24]

d16y1 will be road worthy, you do not need engineer cert. Brakes should be allright, no need to upgrade them.

[jdm_b16a]

So is a D16y1 a B16a but SOHC instead of DOHC?

No. D Series (like D15B4 or D16Y1) are single cam. All use interchangeable bottom ends but you get extra capacity with D16 over D15 plus with the Y1 you get VTEC. B Series is completely different. Not interchangeable with D Series.


Also is the EK/CRV cluster a direct bolt on replacement of the ED?

No. You need to get the cluster plugs from the EK/CRV and graft onto the D16Y1 wiring (assuming you have swapped out the carby wiring). Its all to do with the ECU and electronic speedo. Replacement gearbox has speed controller,


One thing I have to watch out for is P plate rules and the no mod plate's. As far as I know I can only swap an engine in that was offered as an option.

All good with the D16Y1 - same family, slight increase in capacity, uses same engine mounts more or less.


I wonder if the D16y1 would get a roadworthy with drum brakes on the rear, or if I would have to install the rear disks.

Again, no problem. The upgrade is easy and worthwhile but not essential to do the engine swap.

Also, have you read my build thread?

[gen2 CRX]

easiest way to go is get a ED9 crx engine with engine wiring harness, ecu and the fuel tank and pump and lines...or run a aftermarket fuel pump with your carby tank.

[90civicGL]

Once again guys, thanks for all the info. Think for memory your's it the bright blue civic? If it is then I've read most of it. But its been a while, little over 3-4 months that its about time I go update my build thread, and re-read over the ED ones.

Couple last questions about the D16Y1.

Are they easily available? And what car/model are they out of, Was it the upmarket australian EG5?

And i doubt anyone knows this but would it by any chance share the same cv shafts/drive axles as the D15b4?

[gen2 CRX]

they from the EG5..your d15b4 shafts should work.
