You are free to do what ever you like to your own property, but I would prefer you didn't.
FCs are getting rare, the Wankel is special, and Mazda isn't in a good position financially so a new Rotary based car isn't gonna happen for atleast 5 years, assuming Mazda improves its position soon.
I'd rather you not "ruin" a car that I care about. The FC is special to me, and I'd like to keep as many of them as possible "pure". Chances are there will not be any technical benefit, and if you really want to put the motor into some shell, why not a $500 80's civic?

What the guy does to his car is his business. Don't push your ideas on everyone. Deal with the fact that people want what they want. If people love the lines of the FC, and the way an SR performs, so be it.
So, instead of filling the thread with useless arguments that get nothing accomplished but running of a possible contributing forum member, I will say that this is the wrong section to ask this.
Search the "other engine swaps" section and you should get everything you need to know.

First off:
+1
Secondly, this is in the wrong forum. Do as Jerd says and go ask in the "other engine conversions" subforum - ironically listed under Rotary Car Performance.
Third, I will UNhappily give you my negative opinion of your idea if you really want.

There is one forsale in the "se forum" and there is a decent friend who drives at local drift events with one.
Helped swap a sr into a "86" corolla, in terms of difficulty if you do your research it isnt too hard.
The fc with an sr runs great.
Good motors with their own set of problems. Almost every guy with an sr from an importer ive known has dealt woth rod knock

Under-Suzuki in Japan who runs his all-carbon S15 in the Battle Evome and WTAC has had countless rod failures. Most of them simply blown up due to the high-boost situation he runs. But he is running over 700bhp out of his SR. From my knowledge, most stock SR's have a problem with the lifters going bad. It's usually the head that goes bad in an SR before the rods or bearings actually do. And I am not sure if the internals are forged like the KA engines though. Being in the rotary game for a while has caused me to forget some common knowledge on Nissan engines
But I digress!
Back to the OP!

^shows one way of dealing with oilpan clearance, motor mounts, and driveshaft
The gentleman who is selling his seems to have just let the motor sit a bit higher to avoid clearance issues with the oilpan, and ended up with a neat little hole in the hood.

Go have fun,
be different,
you'll have people love/hate you for it.
Personally I'd love to see your interpretation of the swap and how you overcome the problems it poses.

SR's have forged crank and rods, probably pistons too, however evidently they have valvetrain problems along with some shoddy ignition/coil wiring from the factory.
every engine has its own set of issues, its whether or not you decide to be an ignorant hill-jack or shed-yuppie about not fixing them and blaming your engine/trans/car/part failure on it.

Why waste the time on a shitty nissan motor?
If you're going through all the work of getting the motor to fit, mounts, trans mounts, shifter location, driveshaft, wiring, gauges, engine management, cooling system, intercooler piping, etc... Why waste the time on a 4 cylinder?
For the same amount of hassle, you can be doing an LS, or cheap out with a LT.

Because you could have the same power with less weight. Swapping in I4 engines from other cars make the FC a lot like a 944 IMO. But them why not just buy a 944?
Regardless, think it's a cool idea, so don't let others discourage you if you really want to do it. Just be prepared to shove out the $$$$$$$$$$$$ for it.

I was just stating to the OP that it is something to be aware of since a lot of these motors in the states will probably be coming from ignorant hill-jacks and shed yuppies.
As far as bad tuning I thought that the two main causes of rod knock were oil starvation or detonation.
