Hey guys, my name's Lucky and I'm selling my Eclipse for something a little more.. old school

FF sucks so I'm thinking about grabbing an RX-7, there's one right by my house. It's a 1990 RX-7 and I'm going to drop a turbo motor whenever the original engine decides to crap out.
My question is, how difficult are rotories compared to pistons? I know some people might ask you this kind of stuff and I bet it gets tedious too (we get people in the Mitsu forums telling us they has a 700hp DSM lol..), but I've looked at diagrams and read up about rotories and they don't look too bad. I just don't know if I know what I'm getting myself into. I know my engine like the back of my hand, so would enough experience with piston engines be enough basic knowledge to understand how a 13B would work piece by piece from engine to wiring to ecu? I've looked at one, and it blew my mind away how complex but simple they are.
So basically, I have enough dedication to the car, but not exactly the knowledge. Would the RX-7 be a tough car to repair in terms of cost and difficulty in labour? Thanks.
