OK Max, if OS is the Ford and Chevy of the engine world, then in my opinion, the TSI is the KIA. Some people chose to drive a KIA and after 50 to 60K miles throw it away, while others like me prefer to drive a FORD for 200K + miles and still going strong...

The EXTRA money I spend on an OS is the *insurance* policy of MY hobby world. A *premium* that I'm happy to pay because I believe that OS IS better that TSI...
