wth, matt agreeing with me???... Hell you actually even posted other right stuff so I dont need to correct you.... Man maybe people dont all hate me around here....
Anyway.. I have had a few "IC only" cars out here making over 300whp (ok, this was probably 6 years ago) but its a solid setup that IS pretty simple for the average dude to install, as its more bolts and plumbing, than it is actually engine work like a cam install (where you need to pay attention to stuff like torque specs, install methods, timing, etc).
