Honestly, I would prefer an LS swap to a B16 swap anyway. 6th gens aren't particularly light, and the torque will help a lot. The B16 has more hp, but in terms of speed B16a v. B18b in identical cars... really it would just come down to the driver. You'll like the B18B, go for it. :thumbup:

If you can manage to get a gsr transmission instead of an LS one, I'd spring on that too. It will make it a little quicker.
