Rotary powered offroad toy?
I'm alright with building stuff and I've been thinking about making some sort of offroad toy like a dune buggy or a sideby side type of deal. I have access to plenty of scrap steal and welded and most metal tools.
I've been thinking about different ways to power it and a rotary was something I thought about because they make alright power for their size.
For simplicity's sake the first draft will have to be naturally aspirated, what all would it take to run a rotary from an fb or fc seperate from the car. Fb's are carbureted(I think) so this would be fairly simple. What about from an Fc? They are fuel injected I believe. Would I
Be able to just pull the ecu and all other related things from the car and mount them in the buggy somehow and it will work.
Another downside to the rotary is that it would have to be front engine unless you want to do alot of custom stuff. What do you guys think?

12A's from a first gen are carbed, but all 13Bs in from the RX7s are fuel injected. If you tool all of the electronics out of the car and put them in your buggy it would work, the electronics don't care where they are (in an RX7 or not) but you may find that the car is easier to run with a standalone computer so you can get rid of certain pieces of the electronics. Then again, a standalone requires more knowledge of the system in general.
Based on your 'first draft' question you seem to be eyeing forced induction for the future. So unless you want to change motors at that point you have to think about what block you want to start with. Running a TII engine as naturally aspirated is possible if you go the stand-alone route.
No engine HAS to be a front engine, and you are talking about an engine swap anyway so you will have lots of custom stuff anyway.
No offense, but based on your questions you sound way over your head on this.

Obviously you could do some custom stuff to put the rotary in the back but that would either requir a new tranny setup and adapter plates or a really long vehicle which ruins the point.
I think the easiest cheap route is to pick up some 4 banger setup from a front wheel drive car and make that the rear drive axle, so that you can wheelie and stuff.
I'm not thinking about making something sweet and impressive mor like a hick toy.
I don't think I'm totally over my head but I haven't looked into actually doing anything yet. More of thinking about a general plan.
