These motors are probably 15-20k once they reach the track. Just a offhand guess. As my son has spent 13k on a street motor with no tranny mods. Just motor, ported heads, bigger cams, 100mm bore, open source tuning with datalogging and utec piggyback, bigger injectors, bigger fuel pump, bigger oil pump, front mount ic, 8qt oil pan, true cold air intake and a 30r rotated turbo at 26 psi. Conservative tune about 425awhp. Also no water or alcohol injection yet.

Shift "down" to fifth? The STI engine I was talking about is in a 914, so no sixth gear and no "parasitic" awd power loss either. Excepting the aerodynamics the 914/STI would keep up just fine since each car has about 7 lbs/hp, but why on earth would I want to try him on at top speed, anyway? On I-35? In a 914? Wouldn't happen. My fun is more like Hwy 49 between Mariposa and Coulterville, where there isn't a straight more than a quarter mile long. I'm sure as hell not hearing a beep beep from any Corvette on that road.

Any kind of engine running high levels of boost will consume oil, and any OHC engine needs the belts, chains maintained. Nothing special about the Subaru in that respect, one way or the other, and at 100K miles it still beats adjusting valives. From the build quality it sounds like your son knows what he's doing, but every hot rod turbo motor I've ever been around has tempted the owner to turn up the boost until something eventually popped. But since the first post my point has been that when it's in a 914 you don't even have to hot-rod a Subaru engine to have the same lbs/hp as you get in that monster Z06. You can do that with a bone-stock STI motor and have all the fun you want. Except, as you correctly point out, at top speeds on public highways.
