I think you'll find that the only the rev3 3sge was over 170bhp the rev 1/2 was quite a lot less and as for pushing it to 200bhp would require a substantial amount of money spent on it, far more than upping the boost and a fcd on a 4efte Lol at the boosting on stock internals that's why so any people Do 3sgte engine swaps on n/a's believe me I've blown the rod out the bottom on a na there's no way you could boost one safely if that was possible everyone would buy one :-p
