Civic Engine Conversions

[CindyCivic]

Hey all,

I have a 1989 ED Civic and the motor is not to well. I have been told that the crx motor and the integra motor from the same era are a straight conversion, they are injected so the wiring loom will have to be wired, just wondering if this is true and if many people have done it??

cheers Kate

i'm not sure many have as i beleive that that model the integras had d16 & some maybe some of the 1st generation b16s. Not that much benefit if your gonna do a conversion.

If you gonna do a conversion your better off getting the later model b18c from the VTIR which is cheaper or other option is a b16a2 which are more readily avilable or even go for the b18c7 from an ITR which can be quite expensive.

At least you will get a decent upgrade

since you own a ED civic , its carbied and will require abit of $$$ to convert to EFI beforehand. The best bet is the fuel tank / wiring harness etc off a ED8 crx. Then , you can go get B series mounts off a EF8 or EF9 (import with the B16a) and go from there

I think the person must have meant the D16A (also known as the ZC engine )engines from the ED9 aust spec CRX and 1st gen Aust spec integras.

Being a D series engine it would bolt onto your existing ED engine bay, not sure what needs to be done with the wiring though but I suspect you would need the D16 engine's wiring loom to hook up all the sensors and ecu, and of course the electric fuel pump, fuel tank and fuel lines hooked up to make it work.

So sounds easy in concept but still very labour intensive and need all the right parts to make it work. The engine/gearbox may be sourced for $500-1000 pretty easily but for the whole conversion could well set you back upwards of $2.5-4K depending on who is doing the conversion. So depending on how much you like your car it may be more economical to sell your car as is and buy a later model Honda of your choice.

Hey man, honestly, don't bother unless you REALLY like the car!!
If you are just doing it as a cheap way to get ur car up and running again, you are better off looking at upgrading to an early model integra than an engine conversion.

You can pick one up for around the 2-3k mark with resonable k's on it and plenty of life left!!

[CindyCivic]

hey all,

thanks for your help so far, i really like the car. The D16A sounds like the motor to go with, it bolts straight in which is mainly what im after all the other mucking around i can do it can be arranged.

will the gear box from the ed civic fit onto the D16A??

[EKVTIR-T]

Why not just go for a single cam d16?
Bolts up to the existing gearbox and they are cheap as chips.
Just decide if you want vtec or not.

will the sohc d16 fit into a 1st gen integra?

[Kiz_EG6]

No matter what engine you go for, if it is injected, it will be a handful to do the conversion.
As you say, new fuel lines, you will have to find a place to put an ECU, a new fuel tank, or at least modify your existing one with a new pump!!

That's before you bolt the motor in, so i think that engine mounts will be the least of ur worries!!

[EG30]

Glad to hear you really like the car and not minding the conversion not economical, I like your spirit.

I went thru the same myself, wanting to convert my EG Si ( already injected ) with a B series engine with bigger brakes, cams, type r goodies etc and realised it would be cheaper to buy a dc2 integra type R which would come with all the right type R bits.

So I bought a dc2r all the way from queensland last year, and even though it is every bit as competent as they say it is I just couldn't fall in love with it as I do with my little red EG.

I saved and scraped up enough $ this year and sent my car to Sydney to have a conversion done by a forum member. The car should be back in Perth in the next 3-4 weeks.

The 1st gen teg has a D16A putting out 90kw at the fly.
The SOHC Vtec D16 put's (correct me if i'm wrong) 94kw out, i do not think that it would be worth an engine conversion to chase 4 kilowatts, you would probably get more power doing a CAI and header!!

[qikteg]

i'm not really chasing big power from the engine conversion, actually, not really chasing any gains at all. just need something economical to replace my aging d16a3. and rather than replace it with something just as old or worn, or have something old rebuilt, i thought an update mite be nice.

+ sohc has vtec
+ bolt on greddy turbo kit if i want it :)

You could just rebuild ur internals on the d, then GReddy turo too :)
Easy make 120+ kilowatts at the wheels even on stock internals!!

[CindyCivic]

when mentioning the single cam D16 do you mean the standard twin carb motor?? they are quite hard to find actually the d16a i have found a couple of.

[hondavti25]

Hey man where do you live? theres one for sale on carsales in the QLD part...maybe check that one out.

[qikteg]

yeah, rebuilding internals is fine, but i'd still be working off an aging platform.

i'm goin to go with a d16y sohc conversion, something different, and it'll give me all i need to get me for a while
