Starting to figure out the cooling system. Nothing really lines up the way it did in the Miata. Annoyingly, the hot side of the radiator is on the opposite side of the engine bay as the coolant exit from the engine, so the coolant pipes have to cross over. I could probably change this, but it would require a custom radiator to make the air bleed and overflow piping to work correctly, and I'd rather not re-engineer that.

Anyway, coolant exits the cold side of the radiator on the passenger's side, then uses this short section of steel pipe to carry water to the water pump inlet on the driver's side. Because the engine is so far forward relative to a Miata the bend was entirely wrong. So I cut it and re-welded it in a different orientation. Nice little half hour job that saved me a lot of time searching for the perfect cooling hose.
