Well this was used on a D15b Motor, Which is the same family and the cams are pretty much the same so it should fit and work with those two engines,
I am sure there won't be a problem but If there is one it might be with the timing belt because the newer ones might have more/less teeth than the D15b ones but for that you can get the D15b timing belt which for a brand new OEM Honda one costs about 600 RS.
It's an after market cam gear which replaces your factory one, This thing is attached to the cam and is connected via the timing belt to the main crank pully, You can use this cam gear to adjust the power band of the car through different rpm range.
P.S: Forgot to mention that I'll ship it any city in the asking price or a reasonable offer
