I like WRX's along with most turbo cars, but I kind of chuckle at the 1600 degree EGT limit ... most of the Saab tuners out there tune for a "conservative" 1700 for a street car. Suprisingly I've not heard of many turbo meltdowns. I believe Brad from KC Saab has seen some immensely high EGT's for his Viggen, which like mine has Nimonic exhaust valves standard.
The Saabs almost all also have oil squirters for the pistons to keep them cool, forged pistons, and the Viggens, Aeros, and all the newer 9-5 4 cyllinders have Nimonic alloy exhaust valves. Trick stuff! If only every turbo engine came that way from the factory ... :roll:
