I've owned an 02' Maxima, and an 03' Altima, and they are AMAZING cars. They're fun, good looking and well worth their money.
VQ35DE motors aren't that fun in my opinion. They don't handle boost too well. Naturally aspirated they can only make like 340hp(seriously). However, since I'm sure you're not trying to make a racecar out of this, a full rebuild is out of the question, I'd stick with an intake, exhaust and a good tune.
If you do a rebuild, spray the shit out of it, and make sure it's built by someone who knows these motors very well. I made the mistake of trusting a Nissan Tech to build mine, and it only lasted 500 miles after the break-in, and I didn't even get to spray.
