shit man you are right! I looked into it and it was explained to me wrong from the guy I bought my car from. Everyone seems to think this VTC stuff is like VVL/VTEC/VVTI but its not at all. You are correct it appears to be aimed to decrease overlap up top by switching off at 5700 like you say. Well man you can always unhook the solenoid... You really need to get cam gears though with the SR20s to degree the cams in properly. Whereas an EVO 4G63 doesn't need them because they bolt in degreed almost perfectly.
