The tolerence level of SCP10 frame is much less than NCP10, NCP13 and NCP15 frame, i'm pretty sure swaping 2ZZ engine in SCP10 frame is quite equal to swaping 1SZ-FE engine in Mehran, it will be considered fail.
I'm completely not favouring this alteration, because there are many features of NCP family, 4 disc brakes, extra rugged frame and beefy suspension, these features enable the NCP family to hold such hefty engines..
