If someone can show me one bit of evidence where a lower temp thermostat increased performance or lowered KR then I will eat my shirt.
    who works on their car and doesnt tune it to work with the newly added parts? the colder you can run your motor the more power it will make, but the faster it will go away. a 180* thermo is a good choice to run a little cooler. now, if you were to argue the 160* thermo with me then i would agree. that is too cold.

    Apparently I did , but it was only because I read the thread that said I could "drop it in" as a "maintenance item" before doing other mods... I am waiting until I get the downpipe and FWI installed (both sitting in my garage right now), then a seafoam clean, and 104 plugs. Then I will be hunting for a tune to get things working well, and later when I put on a PLOG and then a smaller pulley, I will get a tune again.

    I can't find anyone near me that has a tuner, and I wasn't going to drive 2.5-3 hours to get a tune after putting in a 180* t-stat.

    Your kidding, right?

    Even with a 180* thermostat and your fans set to kick on at that temp, your car is almost always going to run hotter than 180*. Waste of time, waste of money. If you want to run cooler, do it right and get a bigger rad.
