If the FA24 really does have beefier internals, it should respond quite well to mods/tunes.
Good to hear. Prime Motoring seems to have the same observations about the FA24. Granted it's only one example without much testing yet, they've already pushed the stock internals to over 450whp. Time will tell if it'll hold up. But will a stock internal EJ257 hold up at those power levels?

Not talking about maximum potential, the FA20 can make power a lot easier (and cheaper) than the EJ257. If Subaru builds an STI version of the FA24DIT, I have no doubt that it'll be better than the dinosaur EJ257. I think a better HPFP and pnp auxillary port injection system will help push the FA further.
