Hi ,

13B engine is 1.3 l engine .

Some says it's equivalent to 2.6 l 4 stroke / 4 piston engine . OK .
Some says it's not 1.3 , it's 3.9 l , 6 stroke engine .

Ok ok ...

Per cranckshaft revolution , the engine displacement is 1.3 l , it's right ?

So , when i choose supercharger , i need to use displacement = 1.3l/rev ? Or 2.6l/rev ? Or 3.9l/rev ?

Same question for turbo ...

Thanks .
