Over a year ago I rebuilt the 2F in my FJ60 and at the time I had planned on installing a second alternator in place of the smog pump. I first tried to mount a Delco CS-144 (

A couple of threads in the 80 series forum (

http://forum.ih8mud.com/80-series-te...0-150-amp.html) lead me to look at the Toyota 130 (150) amp alternator. 2003-2007 Sequoias have a 130 or 150 amp alternator, PN’s 27060-0F040 and 27060-0F050 respectively. Some V8 Tundras have a 130 amp alternator. I went with a 2003 Tundra V8 130 amp alternator, PN 27060-50300, and hit a small snag with it (explained here

The alternator is slightly smaller than the smog pump. The upper and lower mounts are in nearly identical positions, but the spacing on the alternator is slightly smaller. For the install I used the stock 2F smog pump bracketry. The slot in the upper mount had to be slightly enlarged to accommodate the slightly closer spacing between the upper and lower alternator mounts. A dremel easily took care of this.
