CSI, its cheaper than the Mezeire, has better reliability, and you don't have to clearance the fans.

Another vote for CSR. I bought mine off Ebay, a user had already installed it into the housing. Saved some time and money that way. Fits nicely, no mods to the fans as he said.

Yeah you have to cut away part of the fan shroud on the Meziere. Bad news bears.

There is some modifying the waterpump housing with the CSR. You have to clearance the housing some but its not too bad.

just to let you know i bought a csr brand new and put it on my car and the impeller backed off they put right hand threads on the shaft when the pump is supposed to turn counter clockwise so when the engine heated the water up the impeller swelled up and backed off and blew my head gasket i called csr and said the shaft should have had loctite but it didnt if you decide to go with the csr i called meziere and they said thier impellers are pressed on im sending the csr back to summit and going with the meziere thats fine if i have to trim the shroud cheap isurance btw csr has a warranty disclaimer of any damage cause by thier product so im paying this all out of my pocket they should have cut left handed threads on the shaft bad design

well i would just make sure the impeller is tight once mine backed off i put locktite on it and the seal started leaking because the ceramic seal has a spring to push it against the impeller and there was no way to hold the sahft from turning to tighten the impeller all the way without disassembling the motor and holding the shaft didnt want to void warranty or credit when i sent it back i also looked at the summit pump and they didnt knw who made it and couldnt tell me how the impeller was attached
