what water pump do i use on a b16a, i bought one for a 99 si but then it was to big so then i got one for a gsr it fit but the pully was to small and it made it seem that the timing belt look to big, so where can i get one to or how do i make it fit?

 

I bought one for the del sol with the b16 but I think I remember the 99si one was the same part #, the only difference i saw with the 99si setup was the tensioner was a different #, I used all the del sol stuff and it was all the same.
