most important question to ask is when the engine was rebuilt, and if it has a functioning OMP/and or has been premixed. Check for white or blue smoke when starting up the car, for bad coolant/oil seals respectively. the engine should rev to redline smoothly with no problems, and to be sure conduct a compression test. If all of these go smoothly, the engine should be healthy.

I'm mirin, don't be sad. I own an FC and sometimes wish I had a miata to drive

What makes the S5 meaningfully better than an S4?
Thanks for the advice. Been reading up on the typical issues you encounter. Is it really better to premix than to run the OMP?

The last time I remember posting in one of these, I had just gotten my FD up and running, but it was idling way too high and I just couldn't figure it out. The problem more or less fixed itself since it was the result of the fast idle cam staying totally "open." After an alignment the car drives great and is free of any leaks or heat issues.

I swapped in the wiper stalk (pic related, bottom) and rear sway bar bushings from an RX-8 so my miata is practically rotary powered

OMP much is cheaper, but only certain years of RX-7's can run on it alone. The S5's are notorious for having insufficient oil injection while the S4's are much better in that regard. Additionally, the FD's have excellent systems from the factory while the early RX-8's injected far too little. Later RX-8's had 3 injectors per rotor instead of 2, which helped tremendously. On an FC I would use premix no matter what, but the amount depends on whether you have an S4 or S5, and whether or not the OMP is still functional.
Here's another from that night. Believe me, you don't want to see it in good lighting.
