My goal was to take pride in a build I did myself with results I'd be happy with. Unfortunately, it cost way more than I thought, but in the end it was worth it.
Additionally, a big part of the effort was learning about turbocharging, and an NA-T project will teach you just about all aspects of forced induction. However, I'm not just speaking about making power - tuning idle, cruise, start-up, 2-step, anti-lag, meth injection, etc. comes with the territory. Additionally, you'll learn about driveline components, clutches, brakes, and eventually suspension. From that standpoint, going NA-T was well worth it. In fact, I know much more about the 2jz motor than most of my friends that run the GTE power plant, and I believe they have come to respect the effort and results that are possible with a GE motor.
I still recall picking up "Maximum Boost" by Corky Bell about 8 years ago, and the rest is history.
