being a previous 3fe owner. I think his point is the 1fz is a nicer engine. that said with alittle work (3mm bored out throttle body, serviced injectors tuned headers, extreme valve body in the tranny, after market ignitions system (maybe) ported intake plenieum, the 3fe is as capable as the 1fz but not many people do all the performance upgrades or feel that they are toyota purist to do.
