Doo-Wayne the 85 4wd wagon
ThreeEyedBandit
Band Wagon
First off I don't see much info on the 4wd wagons. Yes, RT4wd, but not 4wd. So let me start here.
I have a 85 4wd wagon, engine stamped as a ew1 with 30psi in most cylinders and leaking oil faster than I can fill it. Yes it ran, but got under 20mpg...
Next I have:
Z6 block
A6 pistons
Y8 head gasket
D15b7 head and all wiring out of a friends 92 civic dx.
This will end with a basically obd1 non v-tech z6 in my wagon hopefully. And filling in all this little problems that arrise. Currently the engie is bolted to the trans and sitting in the car, but waiting to be pulled for the intermediate shaft and last non cracked piston to be installed. Thoughts? Ideas? Boost? Yes it will come, thats just my style.
Pics to follow when I get to a computer.

1-Lower starter bolt threaded boss on the engine doesn't line up. My solution was to make a threaded insert that threads into the now threaded hole of the transmission which accepts the new shorter bolt. Easy and done.
2-Use EW oil pan and pickup, just like the RT4wd swap. Easy peasy.
3-Z6 lower rear bell housing bolts. 4WD EW has two, Z6 has one and is half a hole off. I took the Z6 to work and milled a hole in the new proper location and lopped the top hole off of the rear mount. Should be plenty strong with three bolts, but I also plan on adding a fourth mount to the front of the engine. You could dremel or die grinder the hole into a slot, or even porta band or sawzall it into a big slot.
4WD EW1 sitting next to Z6 block...
Pushbutton 4wd transmission. More to come on this later.
Intermediate shaft mounts. Trying to source a RT4wd one to see if it fits, otherwise I will just lop off the two that don't line up and weld 3/8" tabs in the right location.
And crappy pic of mocked up engine bolted to trans mounted into car. The drivers side mount is the stock EW, with the top hole bored out a little(get a size later) and only two of the studs lining up. More junkyarding to see if I can find one that uses all three, if not the two will work.
Other than a couple of problems that are easy to overcome, this has been very easy to get to this point. Still waiting on one piston to show and the engine will be assembled and mounted by the weekend.
Sadly the hardest and most worrying part is where to mount the ecu. The stock one is under the passenger seat(don't like that idea), and there is NO room under the dash with the A/C. That'll come this weekend.

Good luck this is going to be awesome! In for updates for sure.

1- I lost my EW flywheel cover and the 2wd z6 doesn't fit.
2- Intermediate shaft mounts are modified and in.
3- Use the 4rh gen wagon coolant nipple on the head.
4- Scratched the starter bolt threaded adapter, ground half the head off of a long 10mm holt and stuck it through the mounting hole from the inside out.
5- Engine is mounted for the final time.
6- z6 block and b7 head use the z6 tensioner and b7 timing belt.
7- D series alternator adjuster hits master cylinder slightly, little cutting and it clears.
8- Waiting on my steel fuel line to arrive blows...
9- Obd1 wiring looks pretty straight forward, still need to stash the ecu some place accessable so I can tune it when thr boosy bug hits me in a month.

Engine is in for the final time, intake and exhaust manifolds mouted. Need to bbuild a standoff for the clutch cable so it isn't laying across the engine. Also stock throttle cable would work, but the cable is to short for my liking. Luckily the 4th gem cable has the s ends and is the perfect length!
Crappy pic of the 'rose' interior (barf, but very 80's)
B2 wagon nipple installed. B7 coupe nipple, no go
Stock alternator adjuster
Modified adjuster
Finally clearance!
There's the end of today's progress. Next up is plumbing, exhaust, and wiring.

And proof that a z6 with a b7 head will fit in a third gen 4wd wagon. All in all the getting it in was easy. Combining the harnesses was the most time consuming, and of course the cobbled together exhaust was by far the worst part of the project.
It is a bit tight, but I think I can get a turbo in there later on. First thing is to find a z6 head, wire up the vss, get a real intake, and build a real exhaust. I have some 2.25" mandrel bends and tube that will work great for this.
It's been a long three days getting this ready for work tomorrow, I'm going to relax and try to fill in all the little things I missed later on.

Engine choice was just an experiment and cheapest available parts. Brother gave me a disassemble Z6 short block, and friend had a crashed 92 civic with a b7 and blow head gasket that I robbed parts from. Overall super happy with the drivability and moderate power.
P06. I have the chip, burner and logging interface in the mail as of tomorrow hopefully. Really want to get the vss sorted before it all shows up.
