Think the only difference is the hotside part of the turbo is bigger. It's called a 10.5 where as the 7 turbo has the smaller 9.8 so don't fit one of those.
As nick said though if your gonna upgrade then go so a evo 9 80 series turbo They are more responsive and capable of just over 400 bhp with the right mods
Oh now is your name ted or you just calling people ted ??
