Default 2000 SW2 Bad engine any other options?

2000 SW2 3.0 V6 As this looks to be a hard engine to find in TN are there any other GM options? I would rather have a 2.2 as they are fairly available here. How bad is a 4 cyl swap?

LW2, Totally different car, you'll want to make sure you specify that when you search the yards.

Welcome to SaturnFans!

SC2Sick correctly points out that you appear to be referring to an LW2 which is paired either with a V6 or 2.2L ECOTEC four cylinder engine, and not SW2 which was available only with a 1.9L engince (DOHC or SOHC). Please be clear on your model designation.

How difficult? That's tough to say.

1) You need to verify that the sub-frame/engine cradles are identical so the engine will mount correctly.
2) All engine wiring harnesses must be swapped along with the Powertrain Control Module from the four cylinder vehicle. These mount inside of the passenger compartment forward of the passenger seat whereas the Engine Control Module sits atop the V6 intake manifold.
3) The V6 utilizes a separate Transmission Control Module which doesn't exist on the four cylinder. The PCM monitors and controls both engine and transmission for that engine and transmission pairing (4T40E).
4) You'll need to be sure that the 2.2L engine can mount up to the larger transmission model used with the V6 (4T45E) if you are not swapping the transmission as well.
5) Be certain as to whether or not you'll need to swap the Body Control Module between the cars. The BCM mounts atop the glove box.
6) The V6 engine uses Drive-By-Wire computer controlled accelerator pedal and throttle body. Not so on the 2.2L. You must examine what's required to convert to a cable controlled accelerator and throttle body.
7) The air cleaner box and related tubing must be swapped.
8) Power steering hoses must be swapped. Check as to whether or not the rack and pinion gear are the same for each vehicle. Use RockAuto.com to compare part numbers between the vehicles which have the V6 or the four cylinder engine.

That's what I can think of for now.

I should've thought of this earlier:

9) Air conditioner and related lines will need to be swapped.
10) Radiator must be swapped.

Another item comes to mind about the transmissions. The transmission fluid inlet and outlet piping are likely to be different and perhaps not transferable from one transmission to another.
