i just went through this with my 33... was just gonna be a SUPRISE MUTHA f**kAS sorta thing for wen my car was complete lol...
u need front crossmember with driveshafts, hub carriers etc.. not sure if the 32's suspension is different tho...
u need the complete attesse wiring harness with pump reservoir and computer to make it work for one....
then u need to extensively work the floor pan to get the transfer case and front tailshaft to fit aswell...
being a 32 id probably suggest the rear cradle would need to be swapped out for a gtr item aswell.
and as nismoid said engine mounts need to be changed i dont think the gbox crossmember would even suite a gtst but unsure its alot of work and not for the faint hearted is different and kinda cool but personally not worth the effort...
wat u do now is upto u
