Here's a great writeup on an engine rebuild and swap. Good pics and details - gives a good feel for what's involved. Also good general advice, and the photos are helpful for seeing some of those "hidden" parts of the engine that are hard to see unless it's disassembled.

thanks,
This is one of the most complete write ups I've seen. Makes me want to upgrade my 1.5 na.
