ok, i need to rip out this motor out of the NX 2000...as for the wiring harness anyone know what i need? like can i just clip it somewhere and use some of the b12's harness? and for the big brake upgrade anyone know the whole part list?
The wiring harness you will need off of the NX2000 is the one that runs from the engine to the ECU. It's short, only coming off the engine and ducking in through a hole in the firewall, directly connecting to the ecu.
As far as teh big brake kit is concerned, if you already have the NX 2000 at your disposle get take the front brakes off of it. They are way better than the Big brake kit, which are only SE-R brakes.
Grab a Haynes manual at Canadian Tire, they have all kinds of info about the enigne and wiring harness. If you already have the engine out of the car, you may want to think about doing a tuneup/rebuild. The Hanyes guides you through all this.
The normal Haynes manual for the 82-94 Nissan Sentra should have what your looking for. It covers the SR20DE engine (as well as E and GA series) in depth and has wiring diagrams. The harness will most likeely be the same or very close and its location will proably be similar.
