^^the price you spend getting the k swap + turbo set up u can buy 2 b series motors with turbo set ups that make 400+ whp... but b series is proven to perform just as well or better with forced induction.... there is no comparison on N/A... K-series all the way, plus the first B series vtec motors was late 80's early 90's i would hope Honda would come up with a better motor over the years.....
