Seems like every tuner car except the MKIII has an aftermarket Electric Water Pump available. Someone please prove me wrong.
Electric Water Pump?

i am in the process of looking at designing a kit to do this very process drop in on my build thread i have ordered the parts and then fabrication shall begin
i was going to try and do it so yo could order it as a kit

What's the benefit of switching? Other than just moving things around under the hood for cleanliness.

you can dial in your water temp more or less also it will run the correct ammount of lph for the engines needs ie more at tick over in traffic when it need it so just a lot more efficient the there is a poss powergain for not runnning belt driven pump so overall good thing to do in my eyes although i am sure not everyone will agree with me
The main benefit of an electric water pump for our cars in my eyes is the ability to keep it running for a few minutes after engine shutdown, so the coolant keeps circulating and cooling the cylinder head. The coolant getting too hot after shutdown seems to be one of the major reasons for BHGs...
But this can also be done with a small additional water pump, like many people have done.

Ok, that explanation makes the most sense to me... especially with how hellishly hot our engine bays get.

nah
when the motor is spinning at 5000 rpm the water pump is spinning 1.5 times that much. No electric motor will ever compare to that. The advantage IF it is designed right would be at idle and stop and go where the electric pump CAN flow well past any of the belt driven pumps but install a cheapie or something bad and just as good as a t-stat stuck closed.
I would like to see a pic of an MKIII Pump to see if a simple mod can change things. I know on all Dodge engines all you do is weld a round plate onto the pump and you have no more cavitation. Yes it robs a little horsepower BUT it forces water to circulate at all engines speeds which with a mopar it don't happen once a certain RPM is hit. At that RPM the pump begins to cavitate and stops moving water. Maybe we could do this to the MKIII pump. That simple plate in my old 360 van with a 180° thermostat dropped my temp from a normal 210° on a trailer towing hill climbing 100° hot day to 180° at all times period.

I've been running a 110lph electric pump in series with the stock pump for quite some time now!

Actually I was thinking along the lines of cooling after shutdown as encomiast stated but also to free up some HP. This has been dyno proven on dozens of different cars to free up a minimum of 10-12Hp
i wonder if the impeller can simply be removed thereby reducing the drag on the pulley equal to a idler pulley, then running an inline pump.
Yes in the instructions that come with the Electric they suggest that as a way of doing it!
I just use it as a bypass pump for low rpm in traffic and so on and it shuts off at cruise.

Do you have a link to that model electric pump? Do you think it will be sufficient for a N/A? and are you going to hit 10K tonite?
i don't trust eletrical water pumps so i will never get one there really not need any way far as i know of
but i have all ways liek the idea of coolent free flowing wheil i trun off the car but really it whould have be on for some time plus the t state will close on you so it wonte be really doing it job in less the pump is powerfull eghough to pop the t state
what yae chould do if you are freak about cooling is get new pully a lager one there are chuople out there that will work off otehr toyota's the trucks and such hell it doing even have to be toyota

I use Meziere WP136 20gph pump, it is little cheaper than Craig Davis but if I did it again I would go with Craig Davis, it is lighter and life expectancy longer. Main advantage as mentioned earlier - better cooling at idle.

Life expectancy of Meziere is 2-3 years though they last sometimes 5-7 years as Meziere tech explained. 20gph is the same capacity as mk4 plug'n'play EWP

Why didnt Toyota design the block and the cooling system so that cold water enters the first 3 cylinders and the 2nd 3 cylinders simultaneously?
This way the block is cooled better.
With the current cooling system design, by the time the water gets to the last cylinders the water is already warm and less cooling occurs.
I cant remember if there is a car with this cooling system design?

there water flow is reverse of what most cars is
(ie in the head out the block) instead of in the block out the head
