ok i know in hondas engine swaps are simple since its a toy car in a way lol but how hard is it to swap rotary engines .... cuz my rotary is pretty much screwed cuz of bad owners before me and i found one cheap and i need something that can at least drive so im goin to give it a shot .. since its only 150 for the engine and if it doesnt run then o well i can just take it apart and learn more





But still how hard is it to swap

If you stay within the same series and type (turbo to turbo, say), it's an easy day's work, less if you're all tooled up.

Mix series or swap from NA to turbo and things will take a bit longer depending on how well prepared you are.

how difficult would you say wiring would be if i'm installing it in a car that isn't a rx-7?

Depends on the recipient chassis and the level of integration you're going for.



I'll admit upfront that I've never swapped a rotary into another car, although I have dropped a V-8 into a rotary.

That swap is pretty well documented though, so most of the hard work had been pioneered by others but even so it took a lot of headscratching to finally make everything function.



Just getting the (rotary) motor to run shouldn't be terribly difficult, the hard part comes when you try to make the swap appear seamless...stuff like getting the stock gauges and idiot lights to work can be finicky.



From the eighties on, the electrical systems in cars became increasingly intertwined, intersecting at all sorts of unexpected points (seat belt and clutch interlocks, for instance)and life became much more difficult as a result.



So, the short answer to your question is that there's no way of knowing till you try.
