Is here any reason for putting in a new water pump at belt change time when you can buy one of these for about the same price?

I know nothing about them yet, but the idea looks great.

hi phil!

yeah seems like a great idea. i seem to recall that someone posted something about these units recently.. maybe do a search ?

i was looking at these in the car bible yesterday a.k.a rocket industries catalogue and would be interested to know how they would do in the miata

hey guys, ive got one of these as i wanted to put it into my rx7, im still unsure how much room there is to play with in the mx5 engine bay, but with my turbo setup in the rx7 there was just not enough room to fit the water pump anywhere in the engine bay, they also cant or shouldnt be mounted & should be carried my the water hoses so it also needs a bit of room to float. ive put a pic up tp show you how much room i had to play with. but yeh if the room is there they are a great idea & if you buy one get the controller or if you have a good stand alone computer you can also run the pump off of that. With the rotaries they recommend removing the thermostat & letting the controler adjust the flow through the engine. I hope this helps

Actually, that's with all engines not just rotors. The mania race cars run them. Overkill for a naturally aspirated street MX5 though. For best results, the water pump needs the impellor removed.

My first car was a side valve Morrie Minor. That engine had no water pump or thermostat and worked on the thermo-syphon principle. I'm surprised that a modern day version of that process hasn't been produced after all these years.
