This is an oldie I remember from awhile back from the old days of s2ki, pre-2.0.  If anyone wanted to do an ITB turbo s2k, it’s been done before.  It seems like he is using Jenvey Throttle bodies, a custom Plenum, Meth injection, and a Garret GT35R turbo.  According to the thread he dyno’ed at 555whp 370 ft0-lbs of torque at 18psi, not exactly the best numbers for the money spent these days, but I’m sure the response is pretty nice.
