Alright so I got to talking to my friend about turbo ing my 2001 grand prix gt. he said he can get me a turbo from a semi truck for $100. And he said is friend has done it and works good and he can put it in for me! But I might have to get different headers and then tune and get a dyno of it. Is this possible and safe for my car? I have 100,000 miles on it and it's in good shape just slight oil leak. Would it work from the same as a normal turbo?
