For Srockwood's and Jagt's information, the high compression on a diesel is necessary to generate enough heat for igniton of the fuel. Also, diesels have not always been turbo-charged. The first Cummins put in trucks (called a "JT") was naturally aspirated as was the NT220. The diesels that Oldsmobile & Cadillac used in the '70s weren't turbo-charged.
