Hmm.

First off. Don't tell folks they should go to another site simply because you don't like what they say. That's lame. This is a web forum, it's designed for one thing.....for people to say what they want to say. Plus it's IA. You have lots of people who come here, you are bound to find people you disagree with, just as you will on Tuneratlanta. Got it? Good.

Now, on to your car. Take everything that you hear about Rotaries, divide it by half, wipe your ass with half of the half that you have left, toss it too and what you have left over will be usable information. The NA Fc will last you quite simply forever if you take the proper steps to take care of it. It's only when you start turboing them and building the crap out of them that you run into problems. I've owned numerous ones, 5 to be exact. No FC's though, just first gens and FDs. I can give you a very simple case by case on my FDs.

First FD. 132,000 miles. Original engine, turbos, wiring harness..everything. Owned by an older woman in Florida. Auto trans. I traded it in to the dealer on a BMW and it was still going strong. The harness was well into it's last leg, but all still worked well.
Second FD. Built. Pettie Racing engine, upgraded turbos, 3rd wiring harness. I put 4 engines in that car before I said fuck it and ditched it. I just could not get it right. Had it tuned and everything. Not real sure why, but that car just didn't like motors.
For the money I sank into it, I could have LS1'd it and been Batman.

So if you are going to build one for boost, do it at your own speed. Also find yourself a GOOD tuner. My tuner in Knoxville....not so good. That was my fault and I paid a high price to the tune of 4 motors. Don't be a failure like me.
My advice, keep the motor in the FC, do the bolt ons and go enjoy it. Rotaries are super fun, the NA ones last and last and last. There is a huge aftermarket for them and parts are not scarce. Enjoy it.
