i have a 98 sl1 1.9 twin camand im wondering, are ther any egines that are interchangeable from another saturn?

 

Need to figure out which engine you actually have first.

You either have a 1998 SL1 1.9 single cam
or a
1998 SL2 1.9 twin cam.

If you have a SOHC, a 1993-2002 engine will work. If you have a DOHC, then a 1993-1998 engine.
