Here is a how-to for a 2000 S-series. All s-series struts are the same http://www.saturnfans.com/forums/showthread.php?t=67077

The Saturn sl2 does not have a timing belt, it has a timing chain. And under most conditions it does not need replacing.
Approx $500-$600.
Vehicle does not have torsion bars
Yes, this is a fuel injected engine.
The 1993 Saturn SL2 does not have an inertia switch. Inertia switches are typically found in vehicles equipped with fuel pumps that need to shut off in the event of a collision, but Saturn models from that era did not include this feature. Instead, the fuel system in the SL2 is controlled by a standard relay and fuse arrangement.

I drove my 1995 Saturn sl2 until it had 263,000 miles on it. At that time, the transmission started to slip. I then gave it to a friend, to buy a newer Saturn sl1.
I am prettysure you can change the motor as long as the body structure is the same and you have skill in this sort of thing.
