The Evo8 is more like the Evo6, IMO. The absence of ACD and AYC is a godsend for me. At least I won't have spend more money maintaining this beast
AYC sucks and its prone to breaking after 36,000 miles, so we got a rear LSD instead. The 6spd is brand-new and hasn't been tested for durability in conjunction with the North American drivers, since we tend to abuse our cars more than the rest of the world. The 5spd we have is bulletproof and very strong, much like the previous Evo's have been. I'm 100% satisfied with my vehicle, despite the STi's in the US having a 2.5L inline 4 pumping out 300hp, 300lb ft of torque, as well as DCCD. The Evo8 in the states is already underrated, since it makes 240hp at the wheels from a Dynojet, which would equate to about 300hp or so at the crank. I mean, there's no way in hell a 1480kg vehicle can run a low 13 sec time in the 0-400m strip, right?
About the Skyline GTR drivetrain loss, I thought it was around 15%-18% or so? I know they have less drivetrain loss than other AWD/4WD vehicles out there.
