I just wanted to find out(for my knowledge) that how easy is it to covert from a 582 to a HKS in USA. If your aircraft is registered as an Experimental E-LSA, what amount of paperwork would this kind of major modification create? I know there are places that do these kinds of conversions. I just want to know for my knowledge. I fly an Airborne Edge X and at times have thought of converting it from a 582 to the HKS engine to make it a 4 stroker. Any guidance will be appreciated.
