It should take maybe 2 hours to drop the subframe.
Yours will be easier than mine because yours is a 4 cylinder, so you only have 4 subframe bolts instead of 12 like a V6 car.
It's really not that difficult.

-In the trunk, take off the access panel and unplug the connector in the pump.
-Crank the car for a while to relieve fuel pressure. You could unbolt the pulsation damper under the hood to make sure you have absolutely zero fuel pressure, but I didn't bother and didn't have much fuel come out when I got the fuel lines disconnected, so that's up to you.
-Raise the car and take off the back wheels.
-Drop the exhaust (the flange at the catalytic will probably be too rusty to come apart, you should be able to get the 6 nuts where the exhaust meets the manifold, though.)
-Take off the brakes and tie them up
-Disconnect the ABS sensors at the subframe.
-Disconnect the fuel lines under the car, and the filler and vent hose inside the wheel well (under a plastic cover behind the spring on the driver's side rear wheel well in front of the gas tank door)
-Undo the emergency brake cables and get them out of the way.
-Separate the knuckles from the subframe (there is a bracket that is bolted to the knuckle on each side that supports the brake flex hose, the e-brake cable, I think the wire for the ABS sensor as well, and the swaybar link. After removing the flex hose and the cable/hose, unbolt the bracket and the knuckle should be able to be separated from the rest of the subframe)
-Undo the rear struts from the subframe
-Jack under tank and remove subframe bolts.
-Let the whole thing down bit by bit, making sure it's not getting hung up on the struts (it will).
-Once it's out, you will need to undo the straps, and these bolts will fight you. You only have to get 1 out on each strap and the strap will be able to be peeled out of the way.
-The bolts that hold the fuel pump will probably look hopelessly rusted, but they aren't very tight and will probably come out (I used side cutters to grab what was left of the heads and was able to spin all of them out) The new tanks usually come with new bolts for this. Same story for the evap canister thingy that's in the tank.

The only issues you will probably run into will be corrosion related. You have pretty much the same climate as we do here, and your cars have lots of miles. But you already knew that
Thanks for the write up. I forgot to tell you thanks for that but I guess my mind was slipping. Yes our cars do see similar weather, as we get similar weather here, with similar deicing methods. That new brine stuff they're throwing around these days though is very hard on steel, and seems more active at attacking rust than regular rock salt. I think the only area worse than ours is NY state, as I've got friends that live over there where they literally throw it down on frosty mornings just to use it up :O They say it's a budget requirement kind of thing. Here the county waits and doesn't toss it down unless they find that they need to (savings to the budget).
