Is it an 80 series turbo you got mate? The MR cams may be a little too mild to exploit the turbo, i would go for some GSC S1's or 272's with that turbo setup. The MR cams will fit fine, but the cam angle sensor trigger is a little different.
Evo 4-6 it's a M8 bolt, evo 7-9 it's an M10 bolt.
If you can get the cam angle sensor trigger with the cams, then no worries.
If not, drill out the cylinder to accept the bigger bolt.
Will certainly notice the difference anyway mate.
