I don't know why you are finding this so hard to believe considering you have a turbo car. We dynoed one of my Toyota Supras this weekend ( a 1997 twin turbo 6 spd. from the factory) now has a single 67 mm. turbo, complete fuel system with 85 pph injectors, a set of HKS cams, and 4 in. intake and exhaust. We made 626 RWHP and 570 RWTQ. on 1.8 bar or 26 psi. All the mods on this car totaled right around $4000. Don't get me wrong I also Have a Stage Powered GN so I'm not biased here, I will ride anything that is fast. Those EVO's are impressive cars as well, and I can certainly believe 600WHP. if it was set on kill. Not trying to start a war here, just stating the facts, it's very possible the little 4 banger made 600 whp. Drew
