there are no awd silvias
closest thing would be a gti-r, but that is only because they share the same motor, but obviously the tranny is completely different. actually the normal pulsar may have had awd, sorry too lazy also. but quite a bit of nissans in japan have awd.

lots of the s15 clips are coming with the rear as well, but not true for the previous gen's. you don't need everything though, the front clip is enough. most people will just upgrade their brakes off a z32 or skyline.

if you're looking into this seriously take these things into consideration.

if you're going to do it right, expect to spend quite a bit of money, you will need to find someone who can hook up the wiring correctly or else you will be driving around without all your accesories working. do not buy just the motor, get the whole clip, yeah it costs more but it would be more costly to buy the individual parts that you may be missing if you chose to just get the motor and tranny, especially if the wiring harness is cut.

you're going to need to focus on suspension and brakes first before cranking up the hp on the motor. this isn't like swapping a b18 into a civic, you'll be putting in a motor capable of 600hp on stock internals, and many people have a habit of trying to hit that hp with little suspension and brake work and end up losing parts of their car.
