Another thing ... I just went for a ride in a 83 300D tonight with an auto trans..
engine is retarded to 11* degrees ... ist they bubble timed it and it ran like a dog and nailed. Then they road timed it to 11* and it is a rocket ship...well. kind of

I have read that a 240D 4 spd is equal to a 300D normaly aspirated non turbo..

That is way off.. that 300d with 250k could kick my butt all day long... now I'm startin to get second thoughts.. I better not go for a ride in a turbo!
