I do all the mechanical work that I can, a philosophy that remains from my teenage days of tinkering with cars. Long story short, I was one of the first people (that I knew of anyway) to turbocharge a Saturn, and during the project sought help from a number of performance shops in my area. They all laughed at me, so I told them to fark off. Bought a Saturn factory service manual off eBay and did the entire project without professional help.
