Heat, but not too much and just on the nut not in the hole (e-shaft/PB).
Its held on with loctite AND 360 ft lbs of toqrues
Impact also helps. And a flywheel stop if you dont already have one

just bring it in to my shop tomorrow at some point with the 3/4"-1/2" adapter you have. and find a way to keep the flywheel stopped without using dangerous stuff, like a hatchet
or a screwdriver...you'd be surprised ive heard of people using stuff like that.

Use an alternator bracket and bend it 90*, Use the slide part and the top inspection plate bolt and bolt it there, then use the single hole and slide it over the flywheel's "rod" that poles out on one of the "castle" things. Sorry for the crude explaniation but it works like a charm for me.
Also I use the RB flywheel nut bar and some 2.5" pipe (its actually RB 2.5" 4 foot exhaust pipe).

I had better luck with a breaker bar with a pipe entension and a big ****** hammer. I impacted it for like 15 minutes on and off with full pressure (rated for like 480 ftlbs) to no avail.

The nut came off with no trouble (impact wrench)
But I can get the flywheel off.
So far I worked up a sweat qnd bent lots of steel. I tighten up the center bolt beat on it with a hammer, tighten beat tighten beat
Boy am I beat

Not sure if anyone still is interested...
I just took a sledge hammer and took about a 1/4 swing and hit the clutch surface, it popped right off (keep in mind I was not reusing that flywheel). You don't want to hit the e-shaft or too far out on the radius of the flywheel.
And here's a pic of what I used to get my 2 1/8'' nut off with, that's a 1/2'' drive socket with a 5 foot 1x3 box beam and a 4 1/2' steel bar for digging rocks. The bar is stuck into the flywheel stopper
My dad sat on one side (200lbs) and I sat on the other side (210 lbs) it cracked loose on the first bounce

First rebuild I did, I got ahold of MazdaTrix's purpose-made remover tool and blocker bar. 3-ft flat steel bar bolts to flywheel via clutch bolts, and rests on the floor; 2nd 3-foot steel bar with cast 54mm socket welded on goes on the nut. Heave, pound... off she came.
Getting the flywheel off the shaft was a different story. Typical pullers won't work due to the pilot bearing bore. Tried heating it, tried pounding it, tried penetrating oil... nothing (this was the original engine; flywheel had probably been on for 15, 16 years at the time). Even took it to a local machine shop... they gave it back three days later, having been unable to remove it.
What finally worked: there are a couple of threaded through-holes partway out from center on the stock flywheel. I got a pair of hardened high-grade bolts that would fit through them and reach all the way to the back iron face. I re-threaded the flywheel nut most of the way on, tightened those two bolts up to the point they were "singing" as they turned, put a hunk of 2x4 over the end of the e-shaft, and hit it firmly-but-not-harshly with a 3-lb sledge. BANG! off she came, with a sound like a rifle shot. Shaft and flywheel later tested out just fine.
Nothing like proper force, properly applied.
