and do we need to talk about using that secondhand TPS.?

Please do!

I haven't handed my motor over to the guy I bought the donor motor from yet, so my original (albeit, probably second hand) TPS is still available if I need it. I'm trying to keep the parts swap to a minimum although I did swap distributors, the flywheel for my flex plate and am about to swap the EFE heater because of a broken connector clip...

Which requires removing the 4 long bolts on the top of the TB...

so you can "lift and separate" the TB from the heater (and it's upper and lower gaskets which will also be replaced...

I was going to have to wait for the gaskets until Sunday, but that didn't have to slow me down since swapping the TB heater could wait until after the motor was back in the car.
It took three attempts to get the motor into Shrek. The first attempt was with the alternator on:

Because Shrek has A/C lines, even with wiggling and twisting, there just wasn't enough room to get the alternator past the high pressure line:

Taking the alternator off and mounting the passenger side engine mount & A/C compressor bracket resulted in failure for the same basic reason: Not enough room.
So, when pulling a 4-banger that has A/C out the top, you first have to remove the crank pulley, the alternator, the passenger-side motor mount, and the A/C compressor engine mounting bracket. Then, and only then will the 4 cylinder motor come out and go back in
as "
easily"
as a 3-banger.
On a side note, the replacement motor never had A/C with it, so the extra bolt holes for it had to be cleaned out with some PB blaster spray, a can of compressed air, and a brass "pipe cleaner" that I think I picked up at Harbor Freight a couple years ago:

See the bolt hole I circled on the front of the block? That's one of the mounting points for the A/C compressor engine mounting bracket... and when you're installing the bracket, that bolt has to be
tight before you start tightening the rest of the bolts!
Edit on 9/29/2012:
I think Michael removed the compressor bracket originally, but still, I didn't catch my mistake until after I posted the previous sentence. When I finally got around to mounting the the bracket, I discovered it doesn't have a front face mounting point like Copper Top's '94 factory A/C bracket!! I found aligning and mating the motor to the automatic transmission bell housing at least as difficult as with a manual transmission. Once the motor had been lowered into place, I think it took somewhere over three hours to bolt up (working by myself because the kid didn't come over to help).
Not only did I have to figure out how to rotate the motor clockwise and counterclockwise in front of the bell housing (to line up the motor/bell housing mounting holes), I also had to figure out how to tip front end of the motor up and down to match the same angle on the transmission.
To rotate, I put a floor jack under the oil drain plug (located on the right (firewall) side of the oil pan):

Jack it up, and it would rotate the motor clockwise - and visa-versa. However...
because the drain plug is towards the front of the motor, this also affected the front-to-back tilt.
To change the tilt, I had to use screwdrivers through the chain links & leverage them against the bottom of the hoist's hook to pull one link at a time through the hook, and then jam a second screwdriver through the new link in order to hold it in place so the chain couldn't slide back to the center of balance:

And of course, as the front of the motor tilted up or down, the floor jack would cause the engine to rotate in one direction or another. Raising & lowering the hoist was simultaneously affecting both the tilt and the rotational position of the motor.
Needless to say, changing the hoist and jack heights has to be done in the smallest of increments! Changing the position of the hoist hook on the chain... one link at a time... that really messed with the rotation & tilt!
My first task was to line up the motor's lower rear right (firewall side) through-hole with the stud sticking out of the front of the bell housing:
Attachment:
ThreadingTheEyeOfTheNeedle.jpg
What can't bee seen here is the alignment dowel pin right above it. (There's another metal dowel pin on the bottom front (radiator) side of the bell housing that will have to be lined up) Maybe it would be OK to do it, but once I was able to slide the motor backwards over the stud I decided to NOT put the nut on since I didn't want to risk snapping or bending anything down there if things got screwed up. Sure enough, they did...
At one point the motor slid off the floor jack, lurched forward off the stud, and then dropped slightly downward until all the weight of the motor was completely on the hoist, forcing me to start all over again.
Very gradually things came into alignment until I was finally able to attach both of the upper bell housing mounting bolts:
Attachment:

I then had to put a second floor jack under the transmission to lift it up slightly so the larger gap between the motor and the bell housing to the bottom was pretty much the same as across the top. Then I was able to put the rest of the bolts in the bell housing and attach the motor to the frame. I did NOT cinch up the bell housing to the motor. there's still a gap there - at least until I confirm the torque converter is still able to spin freely and am ready to attach the flex plate to the converter.
Still a long ways to go. This seems like a swap that could normally be done in a weekend, but in my current condition, it's left me doing this off and on for over a week.
I don't think I was able to build up the steam to get started on the motor install until early Saturday afternoon, and it was around 10:30 or 11PM that night before the motor was finally mounted to the frame. The ordeal left me staring out the window at Shrek throughout the day Sunday, wanting to work on it, but mentally unable to take that first step to get started. Finally started to see some relief Monday and was actually able to get out of the cabin and tackle some chores. Temporary setback. I'll get'er done. No need to worry about that.
