I do not condone using regular fuel in the supercharged vehicles, but i had a 1992 SSEi that i had for 2 years and ran nothing but regular and drove that car hard and never had an engine or tranny problem. I also ran regular in my first engine in my current 2002 for a month or two and still no problems. My lower intake got the best of that motor and now i run nothing but 93-95 octane in this engine.
I'm not buying that your motor problem has anything to do with using regular, especially since it was only one tank and the tank couldn't be completely empty so there had to be some premium left in there. I'm going with a few others and saying lower intake gasket. When my lower intake gasket went on my first motor, it took my lower bearings with it like yours. I had the option of replacing the lower bearings or getting a different motor. Replacing the lower bearings is relatively cheap as they don't have to remove the motor from the car. But it'* better and easier to just get another motor.
No matter if you get a reman or used motor, don't let them put Dex-Cool in. Have universal stuff put in instead. Also if you get a used motor, get the lower intake gasket replaced ASAP and replaced with an aluminum framed one. The part number is somewhere here in the forums.
