Good salvages or used engine source?
 

What some places are asking for NB engines is outrageous, north of $1500 for every single one, some as many as 150k miles and asking almost $2k. Locally that is, I'm in Tulsa, OK.

If I had the money, I'd just buy a Trackspeed built engine and move on, but I don't have that kind of scratch at the moment.

Any good 'yards I could work with? I don't mind paying shipping and picking up the engine at the closest dock.

I'm finding it insane I was able to buy BMW I-6 engines for cheaper than a Miata engine goes for now.
