     Looks like it would pump less water but on the other hand you might be able
     to run it faster. The RX8 cartridge is aluminum like the Toyota and a lot
     lighter than the 2nd gen cast iron cartridge shown. A problem
     with the Toyota is the right angle turn in the output. Frankly I would
     have to run the test using the same test rig to draw any meaningful
     conclusions over one being better than the other. Not that it matters
     much. I am sure they are not that far apart. I also don't see any means
     of adjusting the belt tension on the Toyota by pivoting the pump.

The layout we have in mind would be mount the pump low on the side, the alternator above it, the pump stays fixed and a turnbuckle tensions the 5 rib belt.
