Paul,
Can the coolant flow through the block be reversed with no ill effects?  I
am running a remote mount pump (Toyota) and found a block online that
permits plumbing to the inlet,outlet where the stock water pump mounts.  I
am trying to find the best way to plumb the system and reversing the flow is
one of them.  I will keep trying different scenarios.

Not good. The coolant flow direction in the block is critical.
The flow goes in the hot side and the warmed coolant then
flow to the cool side of the block to warm it up.

This reduces the tendency of the block to go into a banana shape
looking down at it from the top. The cooling system is more
sophisticated than it looks. The early NSU engines cracked
the rotor housings right through the spark plug holes
because NSU did not get it right. The water jacket R&D is
still on going the 16B is a total rethink.

The Wankel community spent
a lot of time and money developing it so modify it at
your peril.
