take a sealed coupler and make a small hole in the middle. they sell different sizes at home depot you need a 2in i think. they should be in the plumbing section they use it to cap off pipes. anyway you cut your small hole in it and then put it over the inlet of your turbo. then you blow compressed air in through the small hole and then cover it up with your finger then listen for any leaks. quite simple really. or you could just bring it to my house.
