For 400whp, go buy a Stillen kit and be happy. 400whp NA isn't an uphill battle. A 400whp NA car is a fool's project. You'll end up with an undriveable mess. For power on this platform you need boost.

Yeah I started to look into building a 400 hp VQ. Way too many limitations with VQ heads. And stockish VQ internals aren't up to RPMs you'd need to turn to get to 400. No reasonable way to get there on pump gas in my opinion.

Not an easy road to 400 plus but the HR head race motors are mostly all cranking out over 400. Just takes a lot of work from internals, to cooling and oiling systems, to intakes, to exhaust and engine controls.

And ultimately that 400 hp NA isn't going to be too street friendly

Think low pressure forced induction is way to go for a street car.
