Driveline loss accounts for anywhere from 13-20%. A stock KA puts down roughly 125 at the wheels, but I've seen higher and lower numbers. 200 at the wheels is a tough reach without headwork, higher compression, or SERIOUS ECU tuning. My car put down 159.8 in Tampa a few months ago, the best it's ever done, with an OE exhaust in place. That's with an short intake, S13 cams, Hotshot header, Mueller flywheel, UR pulley, JWT ECU, and running 225/45-16s, so the gearing is closer to a 4.14. With a good exhaust, 164 might be possible. Torque numbers will fluctuate greatly depending on different mods too. My short intake looses torque at the lowend, but picks up higher. You'll never know exactly what you'll get until you try it on your motor. The same setup might do more or less on another car.
