s4 alternator = NA alternator?

Hi guys?

Are the alternators from the s4 and the nonturbo interchangeable?

Label on the TurboModel:

A2T06274
N344 I8 300A
12V 70 A
6Y25I

Label on the NonTurboModel:

A2T47474
N326 I8 300A
12V 70A
1913

The have the same amount of Volts and Amperes and also look very similar...
can i swap them?

They have different plugs, but other than that, swappable

FD alternator would be a good way to go if you have to get an new one anyhow. more amps produced. I need to do that myself soon. i dont seem to be making enough volts with the headlights on and using the brakes....

i think that wouldn't be a great problem, isn't it?

only take the NA alternator in to get my TII one out and get him chromed and powdercoated

edit

Another question

is the complete servo pump with pulleys and brakets etc. interchangeable with the NA ones? will do the same with it as with the alternator *blinbling*
