If you're flexible on your requirements, this combo should do 13's and 140HP all day long, and it's all PROVEN. Buy in one place, dyno-tuning included, set up just the way you want it, no experimentation (read: blown/hosed parts) required. Kits are available if you wanna "Build It Yourself."
Oh, sure, you can continue window shopping like everyone says to do in the
HOPE of "saving" a few bucks here and there, but it's not
their money you'll be spending when the pennysaver part(s) break. And when you compare specs, look for all the so-called "rebuilt" (verses "new") parts; an indication of where they cut corners for that "great" price.
