This is not the first car I have done this mod on.... the car has almost 5000 miles right now and 3 back to back runs at the track..... turbo swap takes about 5 hours on this car.... I WILL admit it, WHEN they fail..... I suspect around 80 or 90 thousand miles to have to rebuild them. I do have to say the car ran 13.06 @107MH which is much faster than I thought it would run at 10PSI @ 700 feet above sea level.
