Will a alternator from a DOHC KA bolt up and plug in to a s13 SR20 without modification?

You need to make the hole bigger were the bolt goes through(upper)

yup you will have to drill a bigger hole where the main alt. bolt is located. Its prob 1-2 sizes bigger than SR bolt. I just got my SR alt. rebuilt.

Yea I just did mine that way, just take a drill dit that fits in the hole perfect and go one step bigger. Some people say u need to shim the sr pulley when you put it on the ka but you dont mine lined up perfect without.
