ok i did homework on the EJ18 and can't figure out what the difference in the EJ18 and the EA82 really is ...
Basically talking, the EJ18 has a Single Timing belt for both heads and has Newer EFi Technology than the EA82, which has two different Timing Belts and weak castings on its first two gens Heads. (There are Three Gens of EA82 Heads)
... can i use the same computer and wiring harness for the EJ that is used on the original EA? ...
No.
... what accommodations have to be made to the trans and mounts to accommodate the EJ
Again, Basically talking, if you want to use the EA Transmission, you'll need an EJ to EA Adapter, also you need to Modify the Engine's Crossmember... and many other things, like to Swap the Wiring Harness and Computer, etc...
The Lowest budget plan could be to Swap another EA82 there, or Fix the one you already have: those are Easy to Fix.
Kind Regards.

An EA81 with hydro lifters ('85-'89 all had hydro lifters, '80-'84 had hydro lifters in automatics only) might be hard to come by where you're at, I don't know. You could probably find one around here for a couple hundred shipped.
I'm not a fan whatsoever of the EA82 but they're really not bad engines. If you're pretty good with engines, you could swap the SPFI pistons out of your EA82 into an EA81 block for higher compression.

generally the absolute cheapest option is fixing the one you have. that being said I think the easiest would be getting a running used EA82 cheap and swapping it in. then take the one you have apart and repair it as you go. then you have a fresh replacement.
of course it depends on what you mean by blown. if its just failing a compression test you may just be able to rebuild a head and keep running it.

... when i say blown number #1 cylinder i mean it has a blown compression or oil ring
Sometimes a compression lost could be due a Blown Head Gasket and / or worn Valve seats and seals... Could you tell some Background info of your EA82 engine? ... Was it working Hot or Overheated before the problem happened?
I Kindly suggest you to take out that EA82 engine and Open it to take a better Look of its internal's Shape, maybe it only needs Head Gaskets and Valve job...
Kind Regards.

Before you do anything, you should attempt to tighten the cylinder head bolts with a 3/8" x 17mm socket, by simply pulling off the camshaft covers. If they can be tightened at all, then that could have been your problem in the first place.

sometimes it's easier to swap what you have than to import a car from across the country
find a whole legacy for a few hundred and there you go. you still need a bellhousing adaptor or some fab skills

I'd pull plugs 1 and 3 and compare to 2 and 4 and do a compression and leak down on 1,3 and 2 (2 for compro sake).

If you're also drinking coolant or blending it, then it sounds like a headgasket. Do you have any record of who did the valve/HG job before?
On the last EA82T i worked on, the HG blew not b/c of the gasket, but 3 of the head bolts had worked themselves out and stripped the block. Now, I fixed it by boring the M11 out to an M12 since an M11 tap wasn't readily available (and it was a beater w/ 165K) and it held great! So incase that's also your issue, there are options. If you do it, just be sure to follow the torque specs TO THE LETTER (NUMBER/ whatever). 3 stages and never overtorque or you'll strip that aluminum.
