what sort of HP are you planning on running? a set of aftermarket cams with adjustable gears "properly" dialed in will probably give you what your after without spending so much$$$$ for very little, if any, gains.
you cant compare a car tuned with vct by just disconnecting it and seeing the difference as you will definitely feel the difference as its set up to run vct!
very hard to compare as every car will "feel" different and react different on the road
