It's a heck of a lot more of a challenge than going boosted too. Making high HP out of all motor is not that easy with a honda. If you are just going for max power then boost is definately the quickest/cheapest way. I just enjoy the allmotor myself. I looked at both and decided I wanted to see if I could hit 200whp with an allmotor b16. I've still got a little ways to go and a few grand more to spend but I think we'll get there.
