Hmm... look up in the archives under GTi-R, individual throttle bodies, etc and
you should find some stuff.  Rob C. also wrote about I think.

Longer runners, more low end; shorter, more upper, IIRC.  I actually have some
friends designing an intake manifold for a class project.  Lets just say that
there are lots of factors involved which leads to a handfull(or more) of
equations which you need to optimize your design for a certain rpm range on a
specific motor.  It's all very motor specific, with things like intake port
area, length, etc. being variables.  So even with two motors of the same
displacement, one design may not be optimal for both motors.
