I've seen plenty of the B230 motor (2.3L) tuned to high 500hp so that is definitely not a problem.

You're right, it's a 2.3L engine and holy smokes, that thing with 500 hp sounds seriously scary. Like a rocket powered sled.

I've seen some extreme builds way past 500hp too, but those tend to be more show car type builds.

You can actually quite reliably get 450-500hp out of a 2.3 redblock without even spending that much money, redblocks are notorious in tuning communities for this, almost like the 2JZ of Sweden

Viva la Redblock.
