I might need a new opti and water pump. Where are some good places to get them? Would a electric water pump be better to buy over a stock unit? I don't want the Meziere, so would a CSI pump be better? Thanks.

 

Here's the man you need to talk to:

Got my opti and water pump from him last summer. Paid a LOT less than my local dealer wanted (they wanted over $400 just for the opti I didn't bother to ask about the pump, I just walked out after that). If I remember right, the vented opti was about $190 and the wp was a little over a hundred.

Some people have good luck with the electrics, some don't. I personally would stay with the stock wp since there is very little chance of it just quitting on you.
