[not to be mean] And if youre racing usdm gsr's then I would hope that you'd win...youre 200+ lbs lighter and its the same exact hp rating (sure torque is different though)
Sure, the difference isnt as large, but it being already nearly 1.8L gives it a much more open field to play with, if we're mentioning that.

If .2 of a liter and 8 more hp is a big deal, then why have you not swaped your motor? I have 45 hp on you - now thats a big deal.

Oh ya, and check the price on a JDM B18C - I could take 600$ of the Extra 1.2K the JDM B18C costs and make my motor out perform it.

Basically, there is not a big enough difference between the B18C and B16A to make it worth the extra $1.2K.
