The Miata's motor started banging around pretty violently on the drive home. I think it's terminal. Where do I get a 1.6 worth a snot or do I just grab the cheapest one from the JY and abuse it again?

We bought the car for $1250 from the sleeziest used car lot on Earth. It had a hardtop, so I basically paid full price for a hardtop and got a free Miata. We knew it had serious issues going in. Even including a "new" motor, I am way ahead of buying a nice one + hardtop. Honestly, I'd just buy a nice one next time.
I imagine it's just the bizarre head noise that sounded like a collapsed lifter coming back, but when entire 1.6's cost the same as a valve job you might as well pull the whole thing.

That's really cool!
It's not that hard to put a 1.8 in there while you're at it....Someone is selling the tb adaptor for $45 on miataturbo.net
WTF? I started it up this morning to see how many pistons were missing, and it ran perfect! No noises, no death throes, just a little blue smoke.
Maybe I should just put a fresh/JY head on it and see what happens...
You should buy this instead-

I'm tellin' ya, your plug wires are goin' bad. I've had the exact same problem. And so have thousands of other Miata owners.
I seriously doubt that my 8-month old Magnecor wires have suddenly "gone bad" and now the motor makes random knocking noises whenever it feels like it. What could wires possibly do to make that happen? It's not running on 3-cylinders, I know that much....
Options:
Rebuild head, hope the bottom end is OK (has good compression) - $1250
Swap in JY motor with warranty (found a 117K mile one for $550 plus core and delivery) - $1500
Swap in a JY 1.8 with warranty (only $100 more form the JY plus $194 from FM) - $1800
Swap in a 5.0 like this car deserves, then break the rear diff - $2500
Sell it for another Miata, keeping my Hardtop and RoTa's - $1000
Sell it, the RoTa's, and the Hardtop, buy something else - ???
Profit!!
Think outside the box: How about a three cylinder, two-stroke Saab engine? If you really want to man the miata up a little, you could use a pair of them.
You'd want to do it mid-engine/RWD, though to get ride of the nasty understeer that setup caused.

I've had to do it on both the 95 and the 99- and I'll bet the OEM wires are better than the Magnegcor.
Or the coil pack- they are pretty cheap, and I replaced mine recently, too.
Don't tear it apart, yet.

+1 for OEM wires and they're cheap to boot. Magnecors, or anything else not OEM, wires suck for Miatas.
