Water pump for fast 102 I’ve done a bunch of research guys, can’t seem to locate the part# for the ls2 gto water pump, it’s going on a 99 z28, and local part stores use the same part number for my car and the 06 gto, I’ve also ground on a new pump and that didn’t work was gonna screw the pump up……Can anyone help?

All LS1/LS2 pumps are the same now, I bought a new AC delco pump last year for the same reason. They are the updated version without that casting bump on the top of the water pump.
As mentioned a LS2 waterpump off a GTO. I will say that I ordered one from RockAuto and it was the same thing as my LS1.
I don't know if it was boxed wrong or what. I ended up finding the AC Delco part number and ordered that from RockAuto and it was correct.

I'm looking at a FAST 102 install and was reviewing the water pump situation.
Many suggesting swapping to the LS2 water pump, but other threads suggest the LS1/LS2 water pumps are the same.
I suppose it makes sense they're the same if the LS1 water pumps were replaced with the LS2 versions at some point.
So for those of you with the FAST 102 intakes...
AC Delco 252846 is the water pump listed for my 2001 LS1 Camaro and a 2006 LS2 GTO. That is the part that I want to use?
Thanks,
Scott

Yes that looks like the correct water pump. If you look at the back of the pump, There's a huge plug that is pressed in that covers the impeller.
On the original style, it had a plate that bolted to the pump instead of that plug. The mounting bosses where the plate bolted into caused the issue with the larger intakes and throttle bodies.
