and with the 3-4g's for an SR you can boost a KA reliably w/ more power so i dont see why youd throw away money on an SR, the only thing the dual cams (KA or SR) has on the KA-E is the high hp possibilities (like550-???) and that isnt what most daily drivers want, but this is an oppinion based debate so no one will convince the other but all i have to say is before dual cams became the hottest thing this side of Japan, everyone was saying the same thing about them and how unreliable they were. So the few brave souls will build what pleases them and we'll go from there
