I have been told by a budding engineer type that using the Mazda RX7 Oil Cooler with internal thermostat will require removal of the thermostat.

My question is WHY?

The thermostat bypasses the cooler until operating temp is reached, so what is the difference between the internal one and an external one?

Oh, cooler will be installed on the scavenge line of a /6 as if it makes any difference.

Why do we have such a fascination with Mazda's ability to cool oil?

I would say buy a Mocal, Setrab, whatever that is the right size, with the right AN fittings, with the right mounting tabs, with the right flow...

With all the money and time everyone spends on hacking together a Mazda unit, you could have a real one.

The fascination with the Mazda cooler, IMHO, is because it is really really close to the right size (within a quarter inch or so, in most respects) it is the same type of construction as the original coolers, it is readily available for cheap and can be modified fairly easily.

No doubt it ends up being not much cheaper than buying a new one, but there are other advantages, as noted above.
