crossmember is the same, mounts are the same, everything should be fine just use the B13 harness and ecu. All the parts you need will come off the sentra. I would do a gasket kit while the engine is out and new clutch aswell. Start with all new fluids, spark plugs and filters. Nothing is impossible.. I swapped my first B14 from GA16DE to SR20DE with just about nothing for knowledge. I had not mentors, didnt ask anyone anythring really, and no help. I just dove in, did it, and I somehow got in running flawlessy. Since I figured it out, I've done it like 5 times already.
