Well the b16a is the 90-93 ls engine if I'm right and the B18c is the vtec I think. Owning an LS, and having ridden in a GSR, I say go with the B18C, the torque difference is just disgusting, and once your over 4 g's, the acceleration you have is seat-mount-breaking..

. Don't get me wrong though. If I take my ls up past 3 g's, the car jolts violently if you floor it. :fawk:
