If you have the tranny you should be able to drop the whole powertrain right in and plug and play. You might think about relocating the knock sensor and disconnecting the balance shafts before you put the engine in the car. I would also go ahead and get a header for it right away. That sounds like a great project... The torque of the QR in a light little 92 SE-R. nice car!

the qr25 has different mounts than the sr20, even in the b15's, those would all have to be custom
you need the ecu and a wiring diagram for both cars so you can splice it all together. From what I've heard the trannies (sr20 5-spd and qr25 6-spd) are very close, and I believe you might even be able to bolt your 5-spd up to the qr25. You also need new axles (if you swap the 6-spd as well) and gauge cluster most likely. The throttle would have to be converted (qr25 is all electronic, sr20 is cable). A lot of money will have to put put into it, but it can be done. Actually I can recall one person who swapped the qr25 into a nx2000 I believe (same basic principle as into a sentra). Pretty much, unless you're being paid to take the qr25 then it's not worth it, because you can get a DET and stick that in, or simply turbo your existing motor, with much less work and money.
