I tried the headers on the motor to see what they looked like for fitting an oil cooler thermostat near the oil filter, it looks kind of tight.
This is tight ! Its a bad angle.
There is just enough room to get my finger in there
I'm not sure if its too tight to the headers for the Improved Racing oil thermostat to fit without soaking up too much heat and the thermostat staying open because of it. I'd like to use the one that fits there but I may have to use a remote inline thermostat.
