Obd1 D17!
A local shop is doing D17 swap in older civic... and they use the old computer to run it! They remove the coils pack on the D17 and install a distributor on the cam...
So you can run it with a OBD1 set-up if you like...
I was first skeptical, but he posted some pics!!!
Here's the D17 in a 98 EK (with a D16y7 IM swap on the D17, running OBD2):
Anyone has done this?
I am not an expert on this, but I guess you can tune the D17 way better with older computer...

yea, that heatshield looks way different from anything youd find in a dx/lx and the thermostat housing looks different too.. then again, i dont know if the valve covers are swappable..besides, what cam would they be using to drive the distributor? and i dont agree, obd1 cars are not easier to tune on..

Rep Power: 304 maybe he's talking about the ability to run hondata on the older ECU vs not on the D17 ECU. that would be a cheaper benefit in some ways. If you could get the distributor,plugs,d16 cam and ecu + maybe harness it might be better for the F/I members who dont wanna drop $1600 on AEM EMS like me.

Rep Power: 0 That was my first reaction too, when he posted the pics... but look carefully
That's a D16:
That's a D17
Look carefully:
a) the oil dipstick is not at the right place...
b) the (i don't remember the exact name) tubing going from the head to the CAI, is not located at the same location
c) the hole to bolt the coils of the D17
So it's at least a d17 head on the first pics.
But I agree for the exhaust manifold, this is not a d17 one... I already asked the question to the guy on the local forum! waiting for the answer...
He said that he used the hole on the side of the D17 to reach the cam..
I don't know how he bolt it to the distributor...
So it's less tunable... I thought it was easier... with uberdata or other thing (but I am a noob on this, like I said!
).
Well, maybe it's
... that's why I wanted advise...

Rep Power: 289 If the rest of that car looks half as bad as that engine bay, why bother?? It is a D17 head, but unless they somehow got the old header to bolt up the D16 block (i have no idea if they're compatible, but i doubt it), that's not a D17 block. Either way, i'm confused.

Rep Power: 289 The pics above show that the head, at least, is off a D17, even if the block is a D16 (i don't know). And, he said it's in a 98 EK. You can tell from the strut towers it's not a 7th gen. I just bolted on a strut bar about an hour ago, so I spent a few minutes staring at my 7th gen's strut towers, and they didn't look like that.

Rep Power: 239 The exhaust bolt patterns on the d17 is a lot different than the d16. even the port shape is different (d16 has exhaust port half again bigger than the d17)
I can see where he might of stuck the distributor
I'm going to do some poking around on the d's I have on stands in the garage and see what it all looks like.

Rep Power: 0 For sure it's sure not GearBox engine bay!!! 
Here another crappier one:
The guy told that it is the complete D17 engine!
He only modified the d16 exhaust manifold to fit the D17 (I guess it is in order to keep the rest of the original exhaust...)
He also said that the D16 transmission is bolt-on on the D17...

Rep Power: 304 maybe because there are tons of D16,B16/18 motors with much more milage and which are becoming more extinct. D17s are plentiful,cheap and apparently not diffuclt to install into older chassis. I wish I had an old beater hatch or crx that I could drop my spare D17 in.

Rep Power: 0 And the goal here is not to show that you can swap the D17 in older chassis, but to show that you can use an older ECU with the D17 and get rid of the not "tuner-friendly" D17 ECU.
It could be a cheaper alternative than an AEM EMS...

Rep Power: 304 Well looking at the pictures, the intake manifold is top mount, i'm pretty sure all of the older D and B series motors have side port intake manifolds. Some D16 parts have proven to be very close if not the same as the D17 parts. For my A2 head swap I had thrown in a Web camshaft which I *think* was made for a D16.
^VTEC motors, yes, the y7 intake manifold is a top mount.
These pics aren't clear enough to distinguish whether its a d17 or not. I would have to look at the exhaust sides of both heads side by side to tell you if its possible to bolt the d16 exhaust manifold on. Not sure if there is clearance or not.
I personally would never consider going d17 over a d16. It is sooooo much easier to make power on a y8 or z6. The d17 is proving a major pita to pull power from, the head is just so ridiculously restricitve....
And yes the d16 tranny bolts up, catalyst did it a while back, just requires some custom cables if I remember right. This may be a route I go later on so I can run an lsd.

Rep Power: 0 There is enough evidence showing that it is at least a D17 head.
However I don't know how he fit the D16 exhaust manifold.. maybe he cut the flange of the d17 manifold and welded it to the D16 one They are too different to fit...
D17
D16
Even the ports don't have the same shape....

Rep Power: 0 Too bad we couldnt see the block to see what it realy is. If the guy said he put a full D17 in there then the block would have the engine code right on it.
i wish we could convert to obd1 for cheap just for the sheer fact that we could run a chipped ecu on uberdata or chrome for near nothing instead of running a piggyback or buying a super expensive standalone
