Hey guys, I bought the KMS high flow oil pump. Now my problem is when I went to install it, it doesn't match my engine. My car is a 95 GSR but it seems as my block might have been a 96 and up because the oil pump is different. I don't know it's really confusing me but someone please tell me which is which? Here are two pics of the oil pumps.....

Is this for ODB1???



....and is this for ODB2???



Also, I guess I'll need to get new timing belt pulley because it's too big, has external teeth on it and won't fit on the current oil pump I have.......
Someone please help me!!!!!

 

You got it right! Top is OBD1 and bottom is OBD2. Should be no difference in timing gears though.

EDIT: The lower timing cover is different between the pumps.

Yes, also look at this picture.....#14 and #15 are also different....#14 should be for ODB1 and #15 should be for ODB2. Those are also pullies just not the crank pulley....

 

#15- OBD2, has the extra teeth on the outside for the senosr, crank angle sensor,
#14- OBD1, not teeth on the outside.

either gear will work with either pump.

No they won't. Thats what screwed me over yesterday when I was putting the engine in. The ODB2 with the teeth will not fit ODB1 pump because those teeth end up touching the oil pump itself....which is why they made two different pullies. ODB1 = without the teeth and ODB2 with the teeth.....also that is used for the sensor......

 

Does it hit the front of the oil pump or the lip for the timing cover? I've never tried the OBD2 gear on a OBD1 pump. I know OBD1 gear on OBD2 pump works. Sorry for incorrect information, my fault!

No problem, but you're right on one sense, that the gear on ODB1 will work for ODB2 but you won't be able to use the sensor....but what happens is, when you look at the pump, u see that border on the oil pump, it starts from the left side of the pump goes around the crank bearing and to the right of the pump, if you look at them closely, u'll see they're different shape. So the teeth hit the border of the ODB1 because it's more narrow....
But KMS said it's high flow and they also said that they never use ODB1 pump so I wonder if they're lying???

 

holy ****!!! I just ordered a type-R oil pump last week cause I blew mine on my LS/Vtec. I had no idea there was a difference between OBD 1 and 2, but I looked back at the pic of it (ebay), and is and OBD2 in the pic, and thats good cause I have a 2001 B18B1 block. Since you guys are already on the subject and know your oil pumps-- the B18C ITR pump will fit on my B18B block right?? The item description says so, but I trust you guys better. And is there anything special I should know before I go try to install it, I do have the helms manual, but its my first oil pump install??? Thanks

If you end up using #15 dont use both #16, found that one out the hard way.
