I just bought a 1985 300SD and was devistated to find out it was a Kalifornistani version. There is a lot of bare metal before the exhaust flows into the turbo and therefore a lot of energy wasted before it reaches the turbo. I was wondering if anyone has tried wrapping the exhaust and cat before the turbo with header wrapping tape. I really would like to know if this has helped any.

Also I'm getting about 21mpg, is this normal for the Kalifornistani verson? My 79 300SD got 28mpg before my crank cracked.

Any other ways to boost the mpg of the CARB crippled Mercedes?

BTW a new air filter just cost me $70. Any body find a suitable cross for this yet?
