Oooof man that's not good. We have interference engines, meaning if the valve timing is off or the belt goes, there is piston to valve contact (interference).
LIKELY CASE: Is bent valves and impact damage that compromises the piston integrity. Meaning the heads come off for new valves, and the bottom end comes apart for new pistons. Essentially a rebuild.
BEST CASE: If your RPMs were low enough that MIVEC wasn't active and you shut her down FAST, you may have some bent valves and very minimal piston damage/dings that you "might" be able to skirt by with. That still means the heads come off for new valves.
Given that there are 6 pistons each potentially impacting 4 valves with goobered timing, and the fragile nature of the cast pistons we have...you're probably going to find at least a couple pistons with damage that necessitates piston replacement. It's a BIG bill that hopefully gets warranteed through the parts company to cover the shop bill.
Here is a parts diagram for reference:
Engine for 2007 Mitsubishi Eclipse | Capital City Mitsubishi Parts
For a piston+rings+4 valves, you're already looking at ~$350 in parts per cylinder. That doesn't include nic'nacs like valve guides or head gaskets. Additionally, you will have an exceedingly hard time sourcing parts. I could not find flywheel bolts last summer (nationwide) as Mitsu stopped sending many parts to the U.S.. Best of luck, I really do hope you get her back on the road.
