Is that an advantage or a disadvantage?... and why?.... come on people I'm trying to learn.
To answer your question, from working with the s14vvti motor and the s13 redtop, in stock for the s14 vvti does produce more horsepower than the s13 red or black top. As long as you keep the stock cams you can keep the vvti. If you swap cams you will loose the vvti which will throw you in the same boat as the sr besides different porting on the head which allows the vvti head to flow more. My suggestion would be to decide what upgrades you are going to do before you decide on the motor. If upgrades include cams then either the s13 or s14 will be fine, just look for the best deal on the best condition motor. If you decide on the s13 you may want to look at the black tops just for lower mileage.
