Renegade recommends using the Meziere water pump with their kit, but I decided to go with a local manufacturer called CVR. Their pumps are a little cheaper, but the build quality is still there. I've seen this pump used on other 911 swaps as well. The inlet/outlet orientation of this pump is not ideal for the Boxster, and given another chance, I'd probably go with the Meziere setup. I got an extra engine mount bracket with my Renegade kit (no surprises there...), which works out great as a pump mount. Below are some pictures of the bracket. Once I have the complete cooling system figured out, I will post more pictures of the pump location and hose routing.
