Will the ITR oil pump gear fit any b series VTEC oil pump? I am assuming that when upgrading to ITR/GSR oil pump from any other b series oil pump, all that is involved is the swapping of the oil pump gears......

I have a b16a oil pump. I have a ITR oil pump gear. Can I swap the ITR gear into the b16a oil pump housing?

 

depends on what year the b16a pump is. There were two sizes.
Though my guess the gear will be the same if they are the same size.

 

BTW: It's a 99' Si oil pump.

I appreciate any feedback. Thanks.

 

should be the same. possibly different pressure spring

 

 

what would be the benifit?

 

No benefit. They are both P72 pumps, as are the GSR, LS and CRV from 96-on.
