Not a good way to start off a thread.
Main reason to go electric is for the gains in hp (roughly 6hp at 6k). To install the electric pump you will need your old water pump, all your really doing is replacing the cam driven impeller with an electric impeller.
You will need to plug the weep hole in the original water pump housing, and a few other things which I believe you can get in a kit.
I would recommend around a 36lb injector, and not sure on the throttle body I would stay stock, or go 52mm.

what kind of "chip" are you wanting to install
maybe a mailorder tune or a dyno tune
most chips/programmers are a waste of money

He didn't start it with that, he ended it with that
Guess I am in that catagory now
There really isn't a down side to it. Both pumps cost about the same. Hardly any fab skills are needed except to notch the fan assembly, if you are using the Mezeire, not sure about the CSR pump.

"The CSI/R pump requires minor trimming of the pump housing. Nothing a file/Dremel/etc. can't resolve in 5 minutes."
It certainly took me more than 5 minutes!! I had to stop often to clear the aluminum that kept blinding the rasp. It was well worth the effort. I've had no cooling problems or leaks. It been running fine for more than 5 years and stuck stopped in traffic recently in 95° weather (160° thermo, 185 on - 170 off) the car never went above 195°. (BTW, Freescan says the gauge tracks the ECU sensor very closely)
Anyone know why the CSI pump has those little lumps that require filing the housing?

Sorry it took you longer. I mocked it up, marked the ears with a sharpie, and rounded them out using a 3/8" sanding drum on my Dremel. Done.
