With similar flow characteristics and .4L more of displacement, lots of available parts, similar-lower costs, I don't see why more people aren't staying KA.

This is true if you don't want to make over 240whp. And pushing stock, high mileage ka's to between 220-240whp you will replace 20ka's very easily. As for the price of parts. I haven't seen a descent pair of rods offered for the same price range as the eagle h or I beams that are offered for the sr20 motors. The cost of pistons is normally more expensive as well. And with the factory sleeved block I can make 398 without swapping the head gasket on a fully stock internal motor. Similar flow characteristics are true to a point, but the ka can't take advantage of the flow without a rod peeking it's head out of the side of the block to say . point is I am sure You can do the same power with either motor when fully built, but for someone who wants to add bolton parts without cracking the motor open and get up to 400whp the sr is way cheaper. Just my
