Back on subject, a stock B17 makes more tourqe than a stock B16...although, put a .25 overbore 10.2 piston and you've made up for the displacement loss and tourqe would be raised. Point is, if you plan on building an engine, it doesn't really matter what the stock ratings are, unless you plan on stock rebuilds (wimp ) then the 1.6vs1.7vs1.8 won't matter that much. I'm building a 2.1 L LS bottom-end. I could still build a 1.8 B16A bottom just as easily. Stock for stock the B17 should be faster. (slightly)
