EHH, its a little intimidating at first, but if you just do your research and take your time, it's not so bad. The interesting thing is how easy it becomes to work on after you have removed all of the over engineered and redundant systems that are useless to the actual operation of the car. Assuming that you don't need to pass emissions, which no one should with a 20 year old car, you can remove a total of 83lbs of electronic CRAP, all of which do not prevent the car from running. Nissan engineers were a little paranoid it seems, I guess its due largely to the long list of problems encountered when they produced the first turbo z and the 280z that preceded it. All in all its a much faster car without all this useless bs.
