They should be close. The FA had a turbocharged V12-244 engine. The PA has a turbocharged V16-244 engine. I would expect that the sound might be a little more 'throaty'....BTW, what sound decoders are you looking at? You need to add in the correct bell/horn soulds as well as the actual power plant sounds.
