Does all FC3S coolers have a thermostat? If so I'm going to get me one

Question is if it can be avooided to run the oil through this pressure valve.

you can remove the valve if you want, when i go to the track i just remove the thermostat

yes, just remember to put it upside down, the thermostat plug facing up so you can unscrew the plug and drain it every oil change.

sorry need to correct myself the thermostat plug facing up NOT down im sorry.

here is another pic of it from my friends car

Now I need to find a 'free-flow' sandwich plate which suits the hachi engine and make some hoses to connect them. Would be great to be able to use the FC oil lines more or less...

Nice SutteR! Let us know wich sandwich plate you go with...

Btw how much did the cooler cost?

I tell you but you won't believe it for sure. It was ~40€ total with the thermostat in and the hoses. Only little bents on the radiator, otherwise great shape.

Adapter will be no problem, I just look for the cheapest but still reliable option.

Hoses with fittings will cost more than the adapter and the cooler I suppose.

Will keep you informed.

Thats cheap! I found one for €100 but we don't have that many RX7s in Denmark, so they don't lay around much

For all you Euro guys wanting to go for the mega overkill RX7 cooler route ... here's one for sale.
