To Turbo or Supercharge

All you gotta do is search for it. Are you insinuating that it’s easy and lots of people have 400hp slant 6s?

Depends on exactly what your talking about, durability and or 400hp?
Not saying it's easy but 400 hp doesn't sound like a pie in the sky number especially if going the turbo route. As for can the bottom end take it, I would believe so unless you point out some weakness?
