I didn't have a renesis water pump housing to send them. They do a lot of impellers for auto racing. I'm not sure how an aluminum impeller would hold up to long term use.

Bobby,
I like it - do they have one for the Mazda, it didn't appear so.

Mark,
 
I spoke with Racemate a couple of years back about machining a better impeller for the renesis. He needed the water pump housing for proper clearances. He looked at the renesis impeller and thought it was junk.

Kelly, 

Keep in mind that I'm comparing it to a 20B water pump, not a 13B water pump.  The 20B pump (housing & cartridge, no pulley) weighs 11.8 lbs.  The Renesis pump & housing after being cut off the front cover is 4.5 lbs.  So, I potentially can save over 7 lbs.  The big question is if the Renesis WP flow is enough water to cool the 20B.  

At present, I'm still gathering parts for the conversion, so I'm currently running the stock 20B pump. 

Any idea what the Meziere pump weighs?  You'll need to add the weight of brackets too.  The Renesis pump will fit onto the front cover same as the stock pump... well, with a few minor mods.

    Beautiful pump but did you see a few posts back that Mark Steitle has
adapted a RX8 aluminum pump to his 20B and reported several lbs of
weight saving..........Jump in here Mark............Photos welcome !!.........
