I've been looking at water pumps since I have mine off right now and I've seen there are several. Which one is everyone using?

Not much of a choice since we have reverse cooling. It's either going to be a stocker, CSI, or Meziere.

I just put on a NAPA reman. $98 with lifetime warr. Works well so far, but the car runs hot when A/C on. Even with my fans on high.I don't know why, it never did it with the original.

CSI and Mez each have their advantages/disadvatages. The CSI needs the pump housing modified, the Mez has pump motor to fan shroud clearance issues. In either case, you'll need a 1LE intake bellows to do away with the silencer tube. I've seen alot more posts about problems with the Mez.

You can still keep your stock intake elbow, you just need to cap it off with something like the bottom of a shampoo bottle.

I run a CSI pump on my setup and couldn't be happier. The temp doesn't change by more then 1 degree during a full 1/4 mile pass.
