ok guys, in my tb03 turbo housing i found a few (2) small cracks. not in the turbo itself, but the other half which connects to the manifold. in other words, the brown half of the turbo. will this cause a problem once installed, or do i have nothing to worry about? also how can i tell if my turbo is any good? is there a way i can check it? heeelllpp......i need boost
