I have a question that is getting differnt answers, can a D16 or D15 non vtec USDM water pump (that is easily found at auto parts stores) fit a JDM d15b vtec motor?, which also brings up will a USDM d15b7 timing belt fit a JDM d15b, i am tuning up a d15 jdm vtec jdm and need to know if the two are interchangable like the other d series, so far most say it fits ok but are the cam gears and other timing belt driven components like the water pump and oil pump going to be ok? Thanks...
