Depends on how many lbs of boost you plan to run. If youre gonna keep it below 10, just go with the b16a, but if youre planning on taking it up to 11, 12, 13 psi on a stock block, def go LS. Although you will see higher hp numbers at the same boost level on a b16, the torque will still be down there. The awesome thing about LS motors is how the torque and hp numbers are close to each other.
