EG: the reduced lift & duration economy camshaft in the special XFI model of the Geo Metro that reduced peak HP by ~10% and shifted the torque curve lower down in the rev range. I put one in my car.
PS: thanks for sharing this info, Fit!
The XFI Metro was the bomb for sure. I had one and I would get around 55 mpg regularly. I wonder if you put the 3A91 1.1 liter camshaft in the the 3A92 you would get better mileage. Torque peak is at 3500 rpm on the 3A91
