i just ordered myself an oil pump for my b16a turbo build.. i ordered the obd1 b16 pump with the part number 15100-pr4-a03.. i was wondering is there a difference between those an the obd2 vtec oil pumps?.. this will be for my turbo build with a goal of 400-450whp give or take.. at first since its pr4 i thought it was for an LS.. but i called honda its for a del sol vtec 94-95.. which im assuming b16, they use those pumps in ALL the obd1 b series . do these pumps flow the same as the obd2 pumps? i know obd2 type r, b16 an gsr are all the same pumps so im just trying to make sure it flows the same and im not making a mistake, i was told there the same an it doesnt matter, i am just making sure.. thanks

 

15100-P72-A01 is what i get for 99-00 Si

 

well yea i know that, im just trying to figure out if that oil pump is any different from the one that i got besides the point that the p72 is for obd2 engines and has a spot for a sensor unlike the obd1 units. i basically just want to know an make sure that performance is the same between the two..
