And so far, I like it. I found a n/t 2.0 at the junk yard a few weeks ago. I pulled the rack and depowered it as shown on tooners and a miata forum. I didn't just loop the lines, I disassembled, did some cutting, readdembled with a lot of grease, and installed. All this contrary to Curtis' advice

Curtis seems to be an advocate for 1.8 manual racks. They get 4 turns of the steering wheel before locking as opposed to the 2.5 of the PS rack depowered. I would imagine that if you found a manual rack in good condition, it would be much easier to go that route as you would not have to put the time into depowering. Just rmove old rack, install new rack.
Overall though, depowering was not hard or overly complicated. I still need to take it to get an alignment, but I took it out for about 10min yesterday driving it around and it really isn't that bad. Definitely gives the car a different feel.
