The 2015 shows an ISL 6.7 liter engine at 340HP and 700 torque. The 2016 reflects an ISB 6.7 liter engine. I have an ISB 6.7 liter engine that's been upgraded to 340HP and 700torque. The related RPMs are the same for all years and mine also. I wonder why the different engines (ISL vs ISB)! I'm not sure of the difference between them.
Pretty sure the Legacy never had a ISL engine.we have a 2014 with the ISB and it did come with heated mirrors. I think heated mirrors are actually a standard e en though listed as an option. I've never seen one without them and we bought back in Jan 14.
These engines are pretty darn amazing how they are very upgradable. If it weren't for the smallish mh2500 tranny these ISB engines would be able to go to 360hp and torque over 800 if I'm. Not mistaken. The tranny is the real limiting issue.
I'm going to look into this engine flash this winter as well. I wonder if there is any real noticeable difference in power or mileage?
