There is pics of everything included It is basically the entire set up to bolt to your car and go it comes with everything you see in pics, even an oil pan tapped for oil return. The crank pulley that comes with it is for an 8-ribbed belt so there will be no slipping of boost it comes with 2 pulleys for boost I believe one is for 7lbs an the other 14lb. I never even mounted this on my car i purchased it from neal sutton and unfortunatly now i have to sell all my honda parts I believe the set up fits b16 and Type r heads i dont know about gsr 2300.
