Pretty sure the only thing about the cam will be vtec or non vtec.
if you dont know 100% dont say it.
jdm d15b and z6 are just about the samething. jdm d15b has larger cam, i installed jdm d15b cam into my z6 head and it dosnt work. valve will stick open.
there is more than vtec and non vtec. do your homework and dont waste money.
reason why i got away with jdm d series motor is because its hard to find upgraded parts.
cheap power = nitrous
