turbo or non turbo

What is the difference between a non turbo engine and a twin turbo engine? I know the non turbo is missing the turbos, but what other differences are there?

the crank, rods, pistons(10:1), oil system, and heads. so just about everything.

Just about everything is right.


If you are asking with the thought of putting turbos on a SL model - do a search here (its been asked a hundred times). Its not a simple job.
