R an S distributors out of minooka, illinois specializes in turbos, free inspection an tear down too, guy RICH will tear it down right there while u wait, (if not busy), let u know whats wrong, what it will cost and usually done by the next day, if nothing needs to be ordered...
rebuilt my turbo for less than $200
midwest fuel injection in bolingbrook, IL does not rebuild turbos, they send them to R an S to get built...
P.T.E. wanted $185 to tear down and inspect.....

HTH, ray
