All of a sudden there is no boost. How do I tell what is the problem. I wanted to take the turbo off and see if it was froze up or something but not sure how to get at it. I am thinking the turbo went out because it doesn't sound like it is spinning at all and the power sucks, can the stock turbo be rebuilt and who does that kind of work, If that is the problem what are your suggestions as far as replacing it with a stock turbo or getting something bigger and what kind of things need to be done for a bigger turbo besides tuning, like will it just fit into place or is there a lot of adaption needed? also what are the turbo models called to find another one like the stock numger or a bigger replacements id number. Thanks for the help!
