how would you do a boost leak test??

 

You will have to make a piece that will fit over the turbo intake on one side and will allow you to put an air compressor hose on the other, make sure you have a pressure adjustment knob on it or you will have all kinds of leeks, 120 psi will do a number on the system. then put the tube over the turbo intake and start with about 10 psi and go up from there. listen closely for leeks. most tuner shops have this setup.
