No . Sorry.  Only have part no. for the 1998 year gen 3.  3sge water pump. 16100-79226.
It has 22 teeth. Round profile. Genuine Toyota (Aisin).
I cant see the very slight increase in rotational speed of the pump being a problem so long as it mates up correctly to the other fixtures on the 5S block.  Cam timing can be compensated for at the cam pulley.
You really need someone who has done this conversion to chime in.

I suppose there's nothing wrong with the 3S pump as long as it fits (I'm yet to test fit everything to the block). I had just decided long ago to use a 5S as that seems like what yhe US guys always use, and it means I have 5S oil and water pumps. I also thought it might make things easier with the hard pipes being 5S Water pump, 5S hard pipes on 5S block. I also read somewhere the 3s pump has a water bypass hose coming out of the bottom and the 5s doesn't, which should be easy enoough for me to check as I have both handy.
