Has anyone else used the Cosworth low temp thermostat before? it became out of stock as soon as I ordered and I searched but couldn't find any other site that sells this individually (without the Cosworth power packages), I will soon install this when I replace the OEM header with the new header and will try running 30/70 mix to keep the coolant temps a bit low.. in theory, it should also help the OEM sandwich plate that come with the DIT OEM oil cooler.. I will report back, I have some other projects too but I will see if time will allow
