Well...
got my borescope/pen caamera today. Wanted to put it ito my RSti to find out what pistons were in there. Had the car for less than 4 months and was running 10lbs of boost with a rich tune. Was told that the rs internals could only handle 6-8lbs of boost before taking a dump. These are def not sti internals...no idea what they are. Anyone seen these pistons before? Seem to handle the power im running through them very nicely. With the vishnu turbo kit, I have had no problems. Thing boost like crazy and holds together great. Headgasket is perfect even after all the ripping I do on the car. I have searched and searched cant find anything even close to these pistons except for pistons that subaru made in the 70s. Any thoughts?

Thanks everyone.

Ben
