You can purchase an SR20VE from SR20Development. They usually have 1 or 2 on hand (they did about 2 weeks ago, so I heard) They know alot about swapping and have a great reputation.
Since you have a 2002 your ECU cant be reprogrammed by JWT (darn 2000+ Nissans). But you have 2 options.
1) You'll have to use a reprogrammed 95-97 ECU from an SE-R and rewire every wire to the ECU.
2) Hopefully you can find a complete VE with the ECU and wiring harness.
Call Chris @ SR20Development. I believe the number is 619-69-TURBO. He'll have all your answers and he's a really nice guy.
