I think the K24 has proven to be a strong engine. I don't know if the FA24 will prove capable of handling boost the same, especially with such a high compression. A built K24 is pretty strong. The reality is that most people just won't be building the car for monster power.
The FA24 will have D4S and high compression, so response, low end torque, fuel economy, etc will likely be better at similar peak power, but I bet a K24 will make more NA power with E85 and bolt ons, but with that high compression, the FA24 will possibly respond really well to E85.
This swap is for a particular audience: someone who blows their engine might really want to consider this over a new, used FA20/FA24 or a rebuild. I can't see many people selling their stock motor, especially a low mileage FA24, just to put this in their car unless they are a Honda fanboy or know the K-series or are hell bent on saving weight and maximizing an NA build. I can also see people doing what solidsnake11 did, as an alternative to a LS or 2JZ swap, do the high hp K24 swap.
