very common on m3 L6 engines though.
I have never drivven anything so responsive to the go pedal as a well mapped set of ITB's on a 4age (16v and 20v)
there's a few 7m-ge engines on MC ITB's driving around here, the sound is amazing, with a higher revving 2jz it would be very nice I think.
ps why is everyone using 20v throttle bodies? they are quite small hayabusa items are 46mm throttle valve and cheap as chips, + a manifold is very easy to make.
we got 240hp 300nm ford pinto's (2.0l 8v sohc) on the busa ITb's at the kitcarclub over here. they bought the iTB's rails injectors and cables for $80
