Cheers guys.
Found out the diff is body kit, turbo, larger ports and vavles, reshaped combustion chamber, higher compressio, intercooler, gearbox - strengthened housing, shot-peened gear set, better clutch, differentials, and suspension.
All this for an extra 22kw and 13Nm over the GTX...
So i honestly have no idea how rob got ~ 40kw extra from just a turbo and manifold...
Oh welps..sal good
