the ecotec, even by itself puts out 140 hp. (unless you have a malibu classic like myself, which has 145 stock, lol). Mated to the 4t45e (auto) its kinda sluggish below 2500 rpm, but wakes up pretty quickly, goes to 6000~ rpm..you'd think it would go higher? Mated to a manual, it goes fairly well right off the line. its impressive. Now, if you could get the VVT 2.4 ecotec it produces 172 (iirc) NA Hp. I even considered it when i had my SE, but..just didnt have the cash.
