I have a 93 EJ22 in my offroader. One thing that has always bugged me is the cast iron alternator mount.So I was wondering if another subaru had an aluminum mount?Same goes for any other bracket on the engine that has an aluminum counterpart.Right now I am trying to remove as much weight from the front end as possible.Aluminum alternator pulley would be cool too.

Assuming you mean the big alternator/ac compressor mount, then yes, the later model EJs had them. Both my 97 and a 96 I'm rebuilding have aluminium ones.

I've seen aluminum pulley kits on eBay. They're usually just the crank and alternator. Dunno about the PS pulley, but those are pretty light already.

Next step would be lightweight flywheel and clutch assembly, you can lose about 20 lbs that way.

If the AC doesn't work (or even if it does) you can drop at least 20 lbs by ditching the compressor, condenser, and hoses.

one year only 2wd legacy 89-91 had no ac light duty brackets
