I own a 1989 civic si swapped with a sohc d15b vtec (1.5L 130bhp). I cant get much info on this engine since they dont exist here (only in japan and europe). This is what i know: -These engines were in the del sols in japan. -1997 was the del sols last year -My engine has a black valve cover with a vtec written on it What i wanna know is if the engine i have, had the possibility of being manufactured in 1997 because thats what i was told when i bought it. I wanna know this because the only engines ive found on the net with black valve covers and vtec on them existed only from 1992 - 1995. 2neItTillYouKillIt
