Jeez.. your gonna have to do some homework guy! but if you wanna find out about your car, i think the best think to do is go get a hanes manual, there amazing i got one when i got my first civic..jus pick one up for a 86-91 civic, as for your engine code, your can find it on the front side of your engine blockits by the leftish side its on a flat piece of casting. it will be something that starts with a D like a D15 or D16 it all depend on what type of civic you have. so thats the engine code! so you for your spring a civic isn't that bad i had 6 poeple packed in my si an it still kinda flew haha but if you want better go the step up with some all-round integra ,you'd be getting rear disk brakes and bigger front disks too, thats what im in the middle of right now, but other then that ..i forget what else you were asking? but i hope that helps a bit, if you can't find it coem back on and tell us what model your civic is, if its a cx,dx,si,2dr,4dr? who knows? ok talk to ya then
