That was painful to read.
Here's the deal: First off, we've been here (240sx.org) since 1997, and actually started a few years before that. So, you'll be hard-pressed to find more / better info on the KA anywhere else.

Third: There's TONS of high-hp KA-T's running around. The SR guys used to have an advantage - not anymore.
Stick around, do a lot of reading in our KA-T forum... here's my build (the engine build is the part you want to read:
