Paul / all



    To make a 20B mount I need the dimensions of the oil pan mounting hole
    positions and I was hoping I could get this from this rotary list.
    Would be much appreciated.   Also, the locations of the holes in the
    windage tray.  I need to know if there needs to be a CG shift  forward
    from the 13B position?



    Also, does the 20B use the same water pump cartridge as the 13B?

    Cozy soon 20b?


    I don't have those dimensions but if you use a 1/8th thick sheet of
    Lexan
    and place it where the pan goes you can center punch the hole positions.

    The need for a windage tray is over rated. The locations are mainly
    a function of the parts such as the pressure regulator and the oil
    pick up tube that must pook through them.

Rick,
If you have a true 20B, then the 13B wp cartridge won't work unless
you use a 13B wp housing too.  The 20B has a larger diameter impeller
and the cartridge itself is longer.  I started to use a 13B wp and wp
housing on my 20B, but changed my mind because it moves the pulley
location to where it rubbed on the crank pulley (would require switching
to a smaller crank pulley).

I'm considering changing over to a Renesis wp as it is 6# lighter. (Paul
is not real fond of the design of the Renesis impeller.)  That would
require you to change to a Renesis front cover as well.  But that would
give you the lighter and more accurate crank mounted CAS.  The Renesis
front cover makes it easier to plumb the coolant lines as the inlet &
outlet are both on the side of the housing.  In my case, it would
require me to rework the coolant lines (again).

I've also attached a picture of my oil pan, showing where the holes are
located.  Sorry, no dimensions.
