Mark /Kelly,

I believe the Renesis is a much improved version of the 13B pump, but can't remember the reasons. I assume it is partly because of the impeller and partly because of the tolerances between the impellor and the pump housing ( being a close tolerance).

Do you have any info on the impellor/ tolerances etc.

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.
