autozone has them pretty cheap,
the n/a ones are around 150 just like the s4's, but the s5 turbo alternator is only $99.99 with the lifetime warrentee, ant the turbo alt is just about the same damn alternator, same output same mounts and everything.
just thought id throw it out there for you guys.

 

what about price on FD alt?? i think that one puts out more amps, would be great mod while your at it, so you can run more electronics in your car

 

i didnt think there was a difference between the NA and turbo alts.

 

i think the position of the battery terminal is different IIRC

 

and the pins on the voltage regulator...
