you should correct you info to probably specify that IPS KME cams would maybe allow full VTC on K20A-2 motors defenetly not the hybrid engines or the TSX engine. I have concluded this through my own testing. My engine was thouroughly compared to a k20a series and I found some Interesting info on many components of this engine. When the time is right i'll release the information. Since the build is currently underweight.
