You are right, DssD is short for Duesseldorf!
Its a 2109ccm with genuine Oettinger 82 mm crank.
edit: Not sure about hp, cause after installing the engine
I had only the pleasure to drive the bug to my garage.
I am not allowed to drive it legal on streets till April 2004.
Hopefully I get some dealers-plates these days to check out
the engines' performance on dyno at
Viktor Guenther soon.
Want to keep that stock appearance of the car and hopefully
I can run the original decklid.
Is it possible?
