its a direct bolt on. ur b16 axels will all fit. im running a 2000 integra type R tranny on my b16a3 and love every min of it. at that time considering a clutch/flywheel upgrade if applicable since the transmission will be off. just make sure the tranny your're getting is a typeR/lsd. a good way to see this is look thru the axel hole, if its hollow thru, u got lsd. good luck.
