Do all D series engines share the same drive axles?

[90civicGL]

So as far as I've gathered all B16 and B18 motors share the same drive axles, I think atleast.

So my question is if people thing D15B4 Axles would work on a D16Y1.

Thanks,
Nick

yes it will work..

[markismaximus]

are you planning on swapping D16Y1 into the ED?

if you are you keep the D15B4 gearbox as well as the driveshafts.

Ok, I'm thinking about it, Cant really afford a B16 right now, so the only options are wait and try find a D16Y1 with harness and ecu and so on. Or repair my D15B4 which I think is the auto choke. But no one including a couple of mechanics really know whats wrong with the engine. So I dont really know how much the D15B4 will cost to repair. Its compression seems to still be strong from the test I did, but it does have 413xxx k's on its clock.

Already got new axles and ignition leads, so If I can use them it makes the swap a little more justifiable. Main thing I'm worried about with the swap though is all the wiring. And I know when you got your RWC they didn't require you to get a mod plate or anything. But I also dont wanna get someone strict come along and say the ED civic never had a D16Y1 in it, need to go get a mod plate, as that would make the car undrivable for me. Although I could maybe get an exception if that did happen as it uses stock engine mounts and is from a earlier civic.

Ah decisions, have to make one soon though.

My D15B4 ran like a dog when I first bought it. Very unreliable, would sometimes just die because the idle was so crap.

I also had the feeling it was the autochoke, as the idle was very very unstable.

Guess I was in a different situation because I knew the motor would be going.

you can use the driveshafts if you swap D16Y1 in but not the leads

All SOHC D series , 91-00 use the same driveshafts.
That is , drivers side short passenger side long

I have the exact same problem that yours seemed to have had, unstable idle and sometimes dies from it, After replacing the spark plugs and ignition leads the idle got a tiny bit better, but still had major problems. Plus mine smokes A LOT, all black though. Got a little oil leak into one of the cylinders which can be fixed with some new lower cylinder seals. Im just not sure if the choke is entirely fixable though. Heard of a auto to manual choke conversion. But sounds like a hard job to carry out.

just do the swap i reckon. cheap, and while you have the engine out easy to change all the seals belts water pump and so on.

you need a mod plate in QLD to swap a D15 to a D16?

Mines a 90 D15, would I still fit into that category?

Not 100% sure, from my knowledge of it all, I thought I could only swap a engine in that was a factory Australian option for the car. But then what happens if you own a car where that option is impossible to find? And B16 is P plate legal, thats a Jap option, So maybe it is internation swaps allowed as well. But then I know a few people that have done the swap and not been hit for mod plate. I think because its just a newer version of the engine from a civic and uses same mounts. But I have a feeling it might be a hit ad miss situation.

EDIT: The Si civic had the D16A6 factory in america, Not the exact same as a D16Y1, But still a D16. So Im not sure how far Australia looks into it all. But its a bit unfair if they dont allow the swap when meanwhile there are plenty of p platers running around in the Jap B16 transplanted into ED6's and ED9's.

well in NSW... if you go within 15% of the max capacity engine offered to the chassis you have then your ok with a blue slip. Anything more requires an engineer certificate. Also engine needs to be newer than your chassis.

SO THEREFORE for an eg5 max they offer is a 1.6. I can upgrade to a 1.8 but anything more would need a eng cert

yes will work, last week swapped a D15b tranny onto a D16y1 motor, we used the d16y1 drive shafts onto the d15b tranny, and fits fine... at first i wasnt sure but as most said should fit with zero problems.

thanks you everyone for the responses

Off topic I know, but a D16Y1 is how much like $500 maybe $800 max if somebody is being hopeful. B16A maybe $1,800-2,200.


IMO just save the extra $1,000-1,500.


But Y1 is still a fun motor if you really wanna budget the build, otherwise I'd say not worth the hassle.

[90civicGL]

If I go with the B route, then it would be a B16 or B18 three years down the track, The pros is that the car will be roadworthy already so can get away with more. Gives me time to get suspension and brakes done properly, or maybe even source out a track specific second car (Just have nothing of my own to tow it with). The cons are I have to wait and am stuck with a D15B4.

but in saying that... might aswell go b18c2 for an extra few hundred bucks....

All d series axles are the same except d16a8 use different passenger axle.

both drivers and passenger is different. Its a different sized spline( larger)....actually the same size and design as B series.

you have the gbox stamp?
i have a hunch you fitted a y4 box to y1.

This was a mates car.... All i remember on the stamp was S20 with alot of other numbers on the side, The gb i brought and fitted to his car was from a eh civic with d15b carby, at first i srs thought it wouldnt work, but realized it was hydro box, so will prbz fit any way, but the end results are good, though it does have shorter 3rd gear, every thing else is same as d16y1 afaik
