I have read that they both will work… “sr/ka”

- KA24DE alternator if used on a SR will need the top hole drilled out a few mm & you need to use the SR pulley, not the KA “have read of people using the KA pulley thou”

All the wiring/plugs are said to be the exact same and plug right in.

“Info from the FAQ on [240sxforums.com](http://240sxforums.com)” quite a few are using a kA alternator + PS pump on their SRs"
