www.fc3s.org has em the cheapest I've seen. ABout $4k! Puls you will need a FMIC, engine mounts, a Tremic T6 tranny, new differential. This is potentially a $10k project! Good Luck!

Theres lots of little things that add up, such as cooling, intercooler, ECU(you cant use the stock mazda one), etc. The installation is pretty straight forward, but it is by no means simple of easy. Be prepared to spend $10K absolute minimum to get it running. If you want to rebuilt the engine and do stuff so that it lasts, $20K if you do the labor, and $30K if you pay someone to do it for you. Physically, there are no fitment problems. There is plenty of room in the engine bay of FC's(unlike FD's) for a 3 rotor.
Unless youre swimming in cash and have plenty of time on your hands, or have enough money to pay someone to do it for you, you would be better off staying with the 2 rotor.

Most of them are about $4K, but you can find them for less from private individuals who later came to the realization that the engine only makes up a small portion of the conversion cost. 
Yes, it will fit in your 87 NA, but making it work is the hard part. I put mine in what used to be an 88 SE, but I also have a TII hood, GXL suspension, and a Series 5 front end (aka "Frankenseven", hehehe). IMO it would be cheapest to start with a TII because you need the hood, and the stock drivetrain would work fine for a stock 20B engine. You could do this for as little as $10K if you were very careful, and do most of the work yourself, but I would budget about twice that to be more realistic.
Here is a site on the conversion:

i dont get why i was advised to get a 2b before as well. It has a higher compression if im not mistaken, and the TII runs at 6-7lbs psi. If he had plans of a higher boost level woulnt it make it more difficult to lower compression to compensate for the higher boost levels? Im asking this because there is not much (to my knowledge) you can do to raise/lower compression the rotary engines. Correct me if im wrong (so i know for future reference)
