The stock turbo is very capable, 350whp+, so it meets the needs of many. As of now, compaired to DSM's, our bolt on turbo upgrades are limited because of the reverse scroll and stock divided exhaust housing/manifold. Most turbo upgrades require a tubular manifold and O2 housing which increases the price. I think within the next five years there will be a good bolt on turbo.
The stock fuel system can support 22psi, but run 92/93 oct. just to be safe. In our tech guide, the last step is bigger injectors and a 255 pump, but it needs to come sooner and definately before cams.
I came from a 2g Eclipse and I'm using the the same AFC-II, cheap'o palm with palm'n'stein, the same OBD-II cable, and it works great. It's just like a 2g.
