I've mentioned a few times that I'm undertaking a Getrag 284 swap into my 2000 Impala LS. For those who don't know what a Getrag 284 is, it's a 5 speed manual transmission that was available in 1st gen W-Bodies with the 3.4 DOHC motor between '91 and '93. As far as I know, I will be the first one performing this swap into a 7th gen Impala, although I'm not the first one to swap it into a 2nd gen W-Body.
I've done a lot of research on this, and I've been getting all of the parts together since October 2011. Finally, last week I felt prepared enough and started to tear apart the car.
I picked up a 92 Lumina Z34 with a blown motor from a member of W-Body.com and trailered it back home from PA.
The car to be going under the knife:
The trans fits, but it is not a direct bolt in. I fabricated a clutch pedal bracket to mount one in the LS. To do this, the entire dash has to come apart down to the mag beam. I've done this already with a spare mag beam I pulled from the junkyard, so that's ready to be swapped in. I still have to mount the clutch master cylinder to the firewall plate. I also have to lengthen the CMC rod about 1 3/4 inch as the distance from the pedal to the firewall is longer on 2nd gens. I plan on ditching the accumulator and running a braided stainless line between the CMC and CSC.
I also have to repair the 284 trans mount, as they are no longer manufactured and mine is broken. I have not been able to source one, so I've ordered some polyeurothane and plan to repair mine with that.
I need to fabricate an intermediate shaft to engine block bracket, that shouldn't be hard.
I'm going to have to have to swap to a steel subframe from a Grand Prix/ Regal, as our aluminum subframe does not have the provisions for the 284 trans mount.
I have a oil filter adapter from an '88 Buick Reatta that I need to modify for clearance with the power steering pump and axle. To run this, I am also switching to the aluminum oil pan and newer style motor mount from an 06+ Grand Prix.
The flywheel is from a L36 Camaro, milled down to 0.84". I've ordered a SPEC Stage 2+ clutch.
The shifter should bolt right in, and I will have to drill a hole in the firewall for the shifter cables. I'm removing the foot parking brake pedal and installing a j-body hand e-brake lever. I'll have to modify the center console.
I think I'm going to need to modify the ignition switch somehow so I can get my key out, as I will be tricking the computer into thinking the car is in neutral at all times.
Kevin @ Cartuning.ca will be doing my tune.
I'm also doing many other mods to this car at the same time.
I will be attempting to swap in control arms from an H-body as they are cast aluminum and the front bushing is horizontal instead of our silly vertical design.
I'm switching from f-body front calipers to c5 Corvette front calipers. I am also installing stainless steel brake lines and rear calipers from an Olds Alero as they are cast aluminum and therefor lighter.
I'm removing the rest of my air conditioning, as it hasn't worked for years and I've been running a bypass pulley.
I have SD headers ready to be installed.
I'm changing out the stock steel front bumper support to an aluminum one from an Rendezvous.
I've also got some other things planned in the future, but I've listed my main goals for now. If the funds are available, next year I'll be top swapping. I already have everything for this except for the necessary gaskets. I'd also like to rebuild the SC I have before it goes on. I'm holding off this year because I'd like to install a XP cam at the same time and upgrade the valvetrain.
Hardware from the Z:
Clutch pedal bracket fabricated:
Preparing to pull the engine:
Obligatory standing in engine bay shot:
Subframe and brake booster out:
Engine on stand, SD headers mocked up:
Interior stripped down, but not stripped down as much as it will be:
Impressive build! You've taken most everything that I've wanted to do to improve my Impala. By the time you're done, it should be pretty sweet, but that's a long road ahead. Definitely keep up with the project, and don't turn this into a dead thread like I've seen many times before. Keep progressing!
Don't dis ma base man! Besides it's human nature to complain. When one starts doing it the rest follow.

Trust me, this will not be a dead thread. I'm well invested in this project and very motivated.
I have my reasons for sticking with this platform.
I grabbed some Bonnie control arms today. Here's a comparison:
I think the balljoints are slightly farther forward on the Bonnie ones, so I'll have to move the rear mount back slightly and fabricate a front mount. Shouldn't be difficult, as I'm swapping to a steel subframe, and I'll be able to weld to that easier.
On Tuesday, I'll be continuing the project. On Tues/Weds I plan on mounting the new control arms to the subframe, getting the motor and trans mocked up on the subframe, fabricate the intermediate shaft bracket, modify the OFA, mount the shifter, run shifter cables, install hand e-brake, and mount the CMC to the firewall plate.
I'm confused. Above, you say you're using driver's side axles and now you say passenger side axles. Are you certain that, when mounted, the 284 will be perfectly positioned so that you can use two equal length axles?

Yeah, I've been taking lots of pics. They're going to help me when its time to put everything back together, and I want a good record of this swap.
Seems most of the people who would do this type of thing have moved on to other platforms. I don't blame them. These cars lack a lot to be desired, which leaves a lot of room for improvement, which I like. I like things that are built, not bought. If I were starting off with a really good car, there wouldn't be as much to improve, and I would get bored with it.
I have a (stupid) love for these cars. I guess my whole family does. My dad has an '09 LT, my sister has an '02 LS, my grandfather had an '02 LS before he passed, my first car was an '00 LS, and I currently own a different '00 LS and a '02 LS Sport. I'm only 22 and I've had 5 W-Bodies in total, and they've been good to me. I have a wealth of useless information about this platform both in my head and saved in word documents on my computer. I even have a press release kit from '99 when they were introducing these cars, complete with "jumping deer" lapel pin.
