Look at the dyno video 3.2 dyno TUNED at 236hp 209tq, not exactly impressive numbers. And the stock miata diff/trans is a ticking time bomb.
Second video, crooked steering wheel drives me crazy, that just shows you what kind of work they do.

That is not a tuned J32A2. The video states that its stock, and looking at the dyno graph in the video, I am inclined to agree. 235/210 at the wheels is typical for a bone stock J32A2. Breather mods on these engines (intake manifold, intake, headers, exhaust) typically bump output to around 265-275whp
untuned.
I had a stroked J32A2 in my 2003 CL-S. It utilized J35 rods and pistons with a J37 crank (which made it approximately a 3.6l) and it was making 294/275 at the wheels untuned. This was before I addressed the exhaust and headers. It was running pig rich above 5K rpm (my AFR gauge was reading below 11:1 from 5k to redline). I have no doubt in my mind that that car would've made 310/290ish, but I parted it out shortly after I got the FRS.
Since I sold that car, Hondata FlashPro was released for the 3G TL, and quite a few guys in the J community have been making 280whp or better on J32A3s. J35s (07-08 TL-S) are making around 300whp with simple bolt ons. If torque is what you're after, get a J37. Those are good for 310/290ish at the wheels with simple bolt ons. Cams are available if you'd like even more power.
These engines can handle about 7-8psi on stock components. 7-8psi on a turbo'd J32A2 is typically good for about 425whp. I know one guy that is running way more than that through a stock block and he's making just shy of 700hp. This, of course, is in a drag civic.
These engines do not make LS power without some form of boost, but they do make very good power when you know what you're doing with them. They're packaged very tightly, and they're very reliable. I didn't have a single problem with my J32 for 50k miles before I stroked it, and I didn't have an issue in the 50k miles afterwards either.
I will agree with you about the steering wheel though.
EDIT- Admittedly, I looked into doing this swap. One of my biggest concerns is finding a good location for the starter. The swap kit in the OP moves the starter below the motor (which requires a notch in the oil pan), which is what they do with S2000 when performing this swap. But on the 86, you've got the steering rack right there. Unless you raise the engine (no thanks), find a way to put the starter on the transmission side, or find another location for it, I don't see how it would fit in the bay properly.
