What engines will work in 78 Wagon
Posted 24 August 2005 - 03:28 PM
I've got a 78 DL that I drove in college. Now it sits in garage and is sadly been adopted as a storage unit. I was driving home from work in '02 when it started to have engine problems. I drove it home 65 miles on 2 cylinders which took some time but amazingly got me home; I have never been stranded by any Subaru knock on wood. I took out the engine and saw that one head gasket is blown. I have not looked at the other side but it has compression. Removing the oil drain pan I found some metal shavings in the pan. To top it off, several of the manifold bolts broke on removal. My impression is that the engine is toast.
What I'm wondering is, what model engines will fit? The old engine is s 1600 #974066. It looks like I will be able to swap bell housing if necessary. I had Rising Sun offering me a replacement for $395 and suggesting it was as easy as swapping the bell. Anybody got any ideas on what would be best?

If it was a EA71 (1600) it should fit directly in?
Also "fit" is a relative term. Anything could be shoehorned in.
How much work are you willing to do?

ANY 1600/EA71 engine will work. The bell housing changeout is VERY easy. It's just 10 or so bolts ...period! It's not a modification. You need to do this to mount it properly in your car.
Additionally, low mileage thin case motors are getting very rare.
Feel free to PM me and we can exchange #s. I'd be glad to help you out.

Oh,and Todd,thin and fat are passe,politically incorrect Ducatis of the 60's were refered to as "Narrow case and Wide case".I've got two narrows of Ducs and two narrows of Subaru.
Please consider keeping it fairly stock.You can drop in several engines with modifications,but you'll have an easy time if you stick with the EA71.It's the work horse engine of the early Subarus.A lot of people feel the EA71 was the best engine Subaru ever had for good reason.
The price from Rising Sun isn't so bad.
CCR might be able to help you.They have a great reputation and you'll even see the owner right here on the board once in a while.

My '78 just turned 87k tonight! Just an old baby.

We did find that the "y" pipe flanges didn't match up to the new engine. We took it to the custom exhaust shop and he cut away the heat shield and discovered a gigantic hole in the "y" pipe. He cut it all out and made up new flanges for $60. He knew exactly what he had to do before we told him, he said it was common on these cars.
The dipstick is different too. The new motor didn't have one, so we thought we could just use my old one. It takes a shorter stick than my original, so we had to cut it down and make a new witness mark for full.
He also changed the distributor to electronic. Everything else bolted up fine.

Yes, I forgot to mention that. The junkyard man even wrote "change pilot bushing" on the slip when I picked up the motor. The clutch kit came with one and was newly installed when the tech school did the tranny swap last fall, so the bearing didn't even have 100 miles on it.
