Thanks. I'm replacing my water pump because it's starting to go bad anyway, but do the electric pumps actually make the engine run cooler?
Besides the relay do I need anything else?

+1 for the relay. you will save a few bucks going with CSR a friend of mine has ran a CSR for a few years now and the ONLY issue was how noisy it is. my meziere is over 3 years old and is still unbelievably quiet. yes they do make the car run a lot cooler as they flow as much at engine idle as the mechanicals do at higher RPMs.

This confused me from the info on the Meziere pump from Jegs...
"Finishing The System: This pump is supplied complete with gaskets and hardware. Factory hardware is reused. There are no other necessary items. "
So what do I actually need a relay kit for?

you need the relay to tie into your ignition unless you want to make a manual switch to turn it on and off. i do not believe mine came with one. oh yea you will have to "notch" the water pump housing to fit a CSR pump. my meziere did not require it.

I have a CSR pump in my car and I have to say its an awesome piece for the price. Mine came with everything need to install the pump minus the "relay kit" everyone is talking about. As for the "relay kit" i don't think its a must to buy. I built my own harness with a relay and inline fuse. Took all of 15 mins to make and cost 8-10 bucks in parts.

Electrical pumps do not vary their flow rate with RPM - they stay constant. So while they do flow more than stock at idle, they do not flow as much at higher RPMs.

i just read a thread about people using the "air pump" hot lead to power their pumps... now that is a lead that is already fused from the factory.... would this be ok to use since im not going to have my air pump set up anymore or do i still need to run a relay off of that wire... ill use the air pump wire as my ignition source...

A lot of people use that fused like and also the air pump relay. Remove the wires leading to the pump and wire in the new ones for the EWP as shown in the diagram. This relay aids in the initial start-up. This is why things are are even done this way from the factory.

That is negligible and should have been a given. Make sure you provide the flow numbers on a mechanical pump for comparison. I am sure he is not building a circle track car so unless he likes to drive redlining everywhere its a non issue.

sorry for this other question, but i got an ewp from another member here and he also gave me the relay, he wrote down some instructions but im not too sure how to wire one connection, he told me to put the wire in the ignition fuse in the fuse box, how do i do that?? stick the wire in and insert the fuse as well?? or what other way can i wire it up??
