hi have i question.. can i use a s4 or s5 N/A alternator on my s5 TII engine? they are both 80 amps i think?.. just not sure if i can use it or not thanks guys..

 

you can use an s5 N/A alternator on your s5 TII, but the post to the neg. terminal will have to be turned 90* to accomodate the stock intercooler/ FMIC piping if yours runs over the engine like mine. The s4 alternators don't produce as many amps, so I wouldn't recommend one, plus it's not a direct plug-in to an s5 connector.

 

exactly what i was looking for thanks !

 

i love this forum btw .. rotaries all day
