thats kinda funny an si with i/h/e only around a 15.4? im not knocking the newer sis becuse i personally like them but they are not that fast at all.ive got a sohc si and my best time was a 15.1 @91 and i have about 120k on it. and i think my car is really slow.but i have gotten beaten by a couple of them on the high end a few times.but the b18c is coming soon.
