I dyno'd 154rwhp with my ka. Though it spun a rod less then two weeks later. True story. I then went and bought and sr then rb20 then rb20 then ca18 then rb20 then rb26 then sr then sr and now am buying another sr. So as you see, after 154whp blew my ka, I decided that even a rb20>ka. And thats a pretty big statement saying there exists a motor that is inferior to the rb20.
