will a vx water pump and timing belt and tensioner bolt onto the dx block?

Im pretty sure the water pumps are different. I remember reading a post about JDM D15B motors using a Vx water pump as if it was different then any other. CX,Dx,Ex,Lx,Si

Dude you need some pictures, your words make no sense.. what motor setup do you have? Is it a D15b2 or a D15b2 with a vtec e mini me swap? what does the following statement mean "so I have a d15b2 dx block and , I am thinking a 1.6 vx civic vtec e head its all on and good to go." Are you thinking of doing it or is good to go????

Its no surprise that the car is running weird. From what I gather you have a 90 civic with a stock block and maybe a vtec head swap using a 92 vx timming belt and a non vtec 90 dizzy and somehow a dpfi to mpfi conversion. With that said I suprised the car even runs!
