Re:B16 waterpump problems! HELP!
 

I ran into the exact same problem. I thougt the Delsol VTEC pump was the right one, but itwas different because my B16A is a 1million series that came from a JDM 90-93 Integra XS-i. If you had a 5 million series B16a (comes from a JDM 88-91 CRX Si-R) Then your pump would have worked. I found that either a b18a pump or a mump for a B17A (92-93 intergra GS-R) will work. Glad i could help. Ps, if you need to know what series your engine is look at the casting serial# under where it says B16a on the block, if it starts with a "1" it is 1 millon series,if it starts witha "5" it is a 5 million series

Re:B16 waterpump problems! HELP!
 

if u were mechanically incline enough to do a mini me swap you;d know which water pump to ask for when getting a new one, wouldnt you :) say, a 92-95 civic ex? hrmm.. why would you tell him a 1.6 91 Si CRX??? thats just setting yourself up for the wrong pump. Lie damn it, say i have a 93 civic EX!! then u get the right pump for a mini me swap no?

thats true i mostly get parts for my b16a1 ither asking for a 99 civic si, and or b18a i have never asked for the del sol but i have never ran into problems with anything most b18a and integra type r motor parts will fit a b16. mostly 90-93 though i think the year continues though.
