a friend of mine is wondering if a jrsc from a gsr can fit on an ITR ? i realize the intake manifolds bolt up different..could a guy order the type r intake mani and put it onto the gsr jrsc?...i dont know a thing about superchargers.....i also realize the gsr kit has more boost than an ITR might like

 

No can do.
The b16 is interchangible with the b18c5...but not the b18c1 (gsr)

 

could a guy order the type r intake mani and put it onto the gsr jrsc?

ya. the bare mani sells for around $200.

 

I don't see why not they are both M62s. You might need the ITR specific double alternator pulley because the shaft size might be different.
