Put it on. And hope for the best.
Its the luck of the draw.
Ive ran a cheap ebay manifold and wastegate on one of my old cars when i was an apprentice. Its still going strong at 400 kw.
My mate had one on for a week and a dag went through his turbo. Even though he cleaned the manifold up he couldnt see the dag.
Let us know how it goes.
