The Houston 240SX scene is pretty big. Help should be easy to come by:

The only thing you'll need besides basic hand tools (sockets, screwdrivers, pliers, etc.) are a floor jack, jackstands, and engine hoist. It's really quite straightforward. These are the sites I've been looking while doing my CA swap (SR swap is the same as the CA one):

Have fun! I went straight into my swap with no mechanical experience whatsoever and it's been a blast. Think of it as an adventure, and be prepared to have another ride around as the 240SX certainly won't be going anywhere for some time!
I'd HIGHLY recommend buying the motor from Jhot Imports, who is a sponser here.
