Kelly, 

Yes, the 20B wp is similar to the 13B, but longer and the housing is larger (two thermostats) also.  The renesis housing will fit onto the 20B, but the studs will need to be replaced with ones that are approx. 1/2" longer.  (I found some 8mm studs at McMaster Carr for about $3.50/ea.).  

The problem is with the pulleys.  You'll have to figure something out on that.  I had a Renesis front hub with pulley.  The Renesis hub won't interchange with the 20b, so I had to have it modified.  Nothing major, but additional work.  You may have better luck getting your pulleys to line up without having to resort to machining misc. pieces.

I got lucky and found a new Renesis front cover, wp, and oil injection pump for $100.  Not too bad a deal.  It was missing the thermostat housing, so I had to make an adapter, but I could have bought one of those pretty cheap from the wrecking yard.  I bought some aftermarket pulleys for < $100.  And as I had stated earlier, I already had the Renesis crank pulley, hub and CAS wheel.  

Now I need to remove the 20B WP, install the Renesis WP, weld up the new plumbing to fit, and relocate the alternators.  See, nothing to it!

P.S.  PL builds & sells a Renesis inlet/outlet adapter for $150.  Adds a bit of weight, but incorporates the radiator cap.

George,
    List on the Meziere pump is $360.00 US + adapters for hose + building
something to mount it to the 13B.............RX8 pump is $138.00 plus you
will need the RX8 front cover (with pump housing built in) to cut the housing
from the cover to facilitate mounting to 13B or 20B..........I have not found
a price for a new front cover and pump combined but I will bet Mark can
tell us...........If a cover can be found used one may save some money.......
 
   Mark just read your reply...........I may not have the info above correct.....
Is the 20B pump housing almost the same as the 13B housing.......Separate
from the front cover ??.........Will the RX8 pump and housing then bolt to
the 20B (or 13B) "With minor mods" ??............

weight saving..........Jump in here Mark............Photos welcome !!.........
