Yes i have ea81 into 78 wagon i used the 4 speed deul range took some shifter mods strut brace mods clutch cable carb hoses mounts worked rad works drive shaft works overall the car performed way better and had high low. Took me about 3 days work but i had whole engine and runing gear to work with. Also had my 81 brat with factory ea81 in old body to compare factory install to mine worked good

I did it in a 77 wagon, the driver's side half shaft housing will rub on the steering shaft although the amount that rubs is low enough that if you chucked the DOJ housing into a lathe and machined it down a bit it probably would not be a problem. If you can swap in the crossmember and steering rack out of an 81 Brat with the 1800 it's not an issue.
For the shifter, the transmission has the bolt holes around where the shift linkage connects at the rear of the case (wish I had a 4 speed to take a pic of) I did have to space the bracket up off the trans with some washers for the lever to work. It would not clear the center console in the car, however I suppose if I had cut and rewelded the lever at an angle it would have cleared just fine.
I might be picking up an early 77 coupe (currently 2nd in line) and if I do it will most likely either get a built EA81 with EFI or an EJ18/EJ22 (haven't decided yet) although the 1600 that's in it has under 100k on it...

I have a crossmember/rack out of a later model '84 hatchback which im assuming will go in with an EA81, do i keep the stock '78 box though? or is it the box out of a later model gen 2you speak of having to space the lever out on?
As for gearboxes I have a very late '80 gen 1 box with Hi/Lo transfer box on it,the box thats in my wagon at the mo is just 2wd/4wd,and it is knackered as it wont stay in 4wd for long....i also have an '89 gen 2 brat box with Hi/Lo ratio transfer and also if i really need it an '84 hatchback with a 2wd/4wd box in....just wondered which would be the most straighforward to put in without too much modding with regards to propshafts etc.... :/
(i have a '78 coupe sat here waiting a new home if you fancy hiring a container lol )

Could you post some pics if you do continue with this swap out? I did an early EA71 to late EA71 swap in my '79, which was very easy of course but a later engine would have always been a better choice.

with both of mine i kept the ea71 cross members and support beam just drilled the motor mount brackets 1'' forward as the engine is 1'' wider and 1'' longer and put washers between tranny mounts cuz it hit a little. its all in adjusting thestabilizer on the top of the engine to get the best steering shaft clearance.
I also ground the bell housing down about a half inch where the bottom left engine bolt is and shortened the stud.....fits like a glove.
