help needed

I'm kinda new to the nissan world. I currently own an MR2 and I need something a little more low-key(cops suck) so I'm looking to build a sleeper in the near future and after doing quite a bit of searching and looking for ideas I've put an older sentra with a det motor in it towards the top of my list. I know a guy in town that has one-but haven't been able to contact him for any information, therefore I find myself here. I'd like to find the following information:

-What det motors and trannies will fit(I keep finding different info.)
-difficulty of the swap
-ease of maintanence(how hard is it to get to the starter, alternator, etc.)
-hidden costs that I will run into
-performance of cars that have done this or similair
-any info on the net that might be helpfull

Also any other ideas to some other nissan sleeper cars would be appreciated. Thank you.

Look on se-r.net it has alot of info.

The more common swap would be the bluebird sr20det. For more info on the swap check this: http://www.se-r.net/engine/swap .
