I would take the B18 over any B16 any day. So much more torque...The B16 dosent have enough stroke to make much power from a turbo. My friend has a Civic, litte done to it, bought a 98 Integra, did a few things to it, then was on his way to a shop to order some goodies, turbo, pistons, rods, clutch, axles, etc, which would have gotten him around 360hp. Not bad for a little 1.8L eh? On his way there someone ran a red light and totaled his car.
