if u thinking about putting stuff from 200b into the Z... don't//.. in modern terms its like putting ford focus stuff into a ford falcon... just completly differant cars... save up some cash and if u want a new interoir... get sulio to hook u up with his vinyl guy that stiched him a new interoir for cheaper than the kit u can buy from all Z parts... same as carpets, get sulio to hook u up and also the seats, l
look on trading post or similiar, or import website for aftermarket seats... always easy to find some half decent newer seats... S15 200sx seats, wrx, or GTR seats, or most honda seats are all awesome.. or just call up some wrecking yards heaps of good seats sitting around, my friend picked up a set of front s14a seats for $40 from a wrecker in dandenong
if the carbs are SU's then, they are for the 4cyl L20 or watever, and would need work on them to get to work with the 6cyl which needs more fuel etc, etc... , but interoir parts, other than seats, and steering wheel and gear lever, nothing else will fit as i am to beleive...
