JAAY are you doing yourself? Let us know how it goes..

Of coarse I am doing it myself. After that look for my base dyno and then my dyno with techno torque installed maybe late next week. It all depends on when my thermostat comes in. My techno torque will be here on Tuesday.

I changed mine in the garage; it's really pretty simple. It took more time to drain the old coolant and mess with that, than install the new t-stat. I even sold my OEM t-stat and housing on eBay to cover some of the cost of the upgrade (car had 16k miles).

My Box nows runs happy and cooler with lower temps and new juice running throughout.

That is hilarious that someone bought a used thermostat on ebay! You can sell anything on ebay!

Is pressure bleeding of the cooling system necessary after opening it up? Wouldn't want get any nasty dry pockets happening..?

Pressure bleeding is a really good thing.. I feel that quite a few of the head cracks that people are experiencing are coming from cooling systems with pockets that create hot spots..

I bought the t-stat from jmatta. I wanted to get a cheap t-stat that I could do a little work with. When I used to drag race Chevies, one of the tricks we had for cooling was to drill a couple of small holes in the plate that opens and closes. This does two things. First, it gets a little coolant flowing before the t-stat opens. Second, when the t-stat is open, it provides a bit more flow.
So, I've done this with the used t-stat. Here's what I'm seeing:
Once the car gets up to temperature (which does take longer now), the average running temp shows lower than before. Before, my gauge read anywhere from straight up vertical to the far right side of the "0" in the "180". Now, on the highway, the temp stays on the hash mark under the 180. In town, the needle will move over to split the "8" and the "0", but I have yet to see it go as far as it did before. Once I get moving, the needle will move back to the left of vertical. This may be due in some part to a modification I made to the center radiator. I've put GT3 RS type openings in front of the hood, moved the radiator forward about 1", and routed all of the air through the center radiator to exit through the RS ducts, over the car.
My biggest reason for experimenting with the t-stat was the cost of the LN model. I trust their data on the value of a cooler running engine, but when 944, Audi, Benz, etc low temp t-stats are $30-40, the cost of the LN model is a bit high.
