VERY good info man, well done, couple things I noticed. Not just making this up aswell (I performed RSF98's swap
For the AC compressor, if you want to keep the factory AC lines, the compressor to use is from a 95 3100 Buick Skylark. You will also need the little bracket that goes between the engine and compressor from a 94-96 Grand Am for this to work. Here is a picture where you can kind of see this compressor mounted. With this setup I also use a 95 3100 Grand Am belt.
If you are going to use the 94-96 N-body top mount and shave down the engine bracket, you will only need to trim it about 3/4 inch, thats what I did and it ended up perfect.
I though I would put up a pic of the custom lower mount bracket that I made aswell, so you have a general idea of what to do if you tackle making one yourself.
In terms of wiring, I spliced a 2003 Alero wiring with the 98 Sunfire harness. I used the 3400 pcm to run the engine and used HP Tuners to get rid of VATS and all the auto codes and used the J-body PCM to run the gauges. This setup worked pretty well, so this is another option for wiring aswell.
Thanks for taking the time to do this
All the major issues on one page
I know that there are some differences between the 3100 and the 3400, so here's a couple things that I did:
Fuel lines: the lines from the Eco will work well, as they have the same click-on connections as the newer 3x00 engines. You can also custom make lines that match up to the older style lines on the J-body. This will require flaring and bending tools.
My 97 Fire had the clip on connectors that mated to the 3400 with ease (in case one needs to source parts)
Heater hoses from a 99+ N-body (this also requires the engine pipe to the heater hose from the 3400 in place of the one that comes on the 3100)
I trimmed back the J hoses a couple inches and used some worm gear clamps to hold them in place. I'll get pics when its daytime
The 3400 can be switched over to the 3100 setup, it will require however, the removal of at least 1 pulley boss for clearance for the Y bracket as well as the tensioner bolt from the 3100.
Since this is a compilation of info, one more tidbit of info:
The starter from the 2200/2.2 OHV will bolt to the 3400, so if one gets an engine from a yard w/ no starter...
Actualy, for the heater lines. The 3400 montana lines go up towards the brake master aswell. The Grand am lines wrap around the back of the engine.
Can anyone give me a little more detailed instructions on the install for a 99 cavalier with 2.2 to a 3400. I was wondering about the dimensions for the engine mounts and about the wiring, do I need to swap the computer from the 3400 , and can I use my cluster?
Lower engine mount: Please read through the 3rd Gen V6 swap threat (i know it's huge) but you'll find information in there about use of what computers we have used for the swaps.

you will need some sort of computer swap. the 2.2 ECU won't run the 3400.
I'm using a stock 3400 PCM w/ an initial custom tune by Milzy Motorsports to remove the auto trans stuff, then will be going through further tuning by me. RSF98 is using a stock 3400 PCM self-tuned for the same function (03 Alero). SHOoff is using Megasquirt, Quiklilcav is using a Camaro PCM.... the second gen guys use a rechipped 3.1l PCM, others have used a 1998 3.1 PCM (apparently an easier way to bypass the theft lock and for OBD2 compliance)
Depending on what your computer source will depend on the harness source (however if getting a 2000+ 3400, you have to get a 2000+ harness due to changes in the injectors) which will then depend on the wiring, or swap in the 99 injectors AND injector harness if using a 1999 3400 engine harness.
Given that there are that many options to run the engine, there are the same number (if not more) of ways to wire it in.
Now the gauges are another story. 2 options... custom dash or piggyback your 2.2 computer to drive the gauges.
Sorry it isn't a straight forward answer, that's the best I can summarize the 30-something page thread.
Mechanically, its the same as the first post.
u mentioned about the delete again, what makes it possibile to delete, something i can buy? or somewhere i can go
the standard VCM suite is what i need? 500$
yep standard will work. pro if you want no-laptop logging among other features
May I ask from a moderator, since this is a sticky that it be locked. And from that point on only be added to if someone has information, pictures, diagrams, and such to add to it. That way we don't turn this into another 40 page discussion.
a good idea is to put some light strength thread locker on the lower mount plate bolts to keep them from vibrating out like my front one did, leaving too much stress on the back bolt. and breaking the oil pan
posted this in the other thread but figured the info thread would be a better place for it
My 3400 Swap Page
I would like to add my 2 lincolns.
My swap was a 2001 cav 2.2 auto, with a 2001 3.4 grand am gt auto.
This grand am transmission Is a direct drop in and drive, cav axles pop right in. I believe only 00 and 01 gam gt's will work in this application.
If the 2001 Grand am steering rack is swapped the n body ps lines are direct bolt ins. The rack is direct bolt with the exception of the outer tie rod ends. Same ratio and lines are exact fit. This is if the rack is an available option for you in the budget. I dont know how many years the rack covers.
It is not necessary to hook up the power assist solonoid on the Power steering pump. Just make sure if you have this style pump that you order lines for variable assist. they are different. You cannot use this feature because it goes through the ABS system of the N body and has a sensor on the base of the column which the J doesnt have.
On 00+ to 00+ swaps you can connect the serial data lines (purple wire) from the 3.4 Pcm to the J body serial data. this will allow the function of the cluster minus the fuel gauge.
piggy back the 00+ pcms by using the serial data lines. ie. use the n body pcm for the engine and use the j body pcm for the fuel gauge... This will cause hundreds of miles to be put on your odometer when the ignition is cycled on and off.
00+ cluster fuel gauge will not work with the 00+ N body PCM. An aftermarket a pillar gauge can be purchased through Dakota digital at www.summitracing.com
I used the N body 3.4 a/c compressor, and the cav plumbing, the line had to be gently bent to fit but works great.
If using this line combo, and n body dual fans, be sure to grind out some of the fan shroutd to allow access to the a/c charging port later. As said above, that the n body lines will work, I think that one was missed. My research shows that they wont work. the ends of the lines are different, and are different lengths since the n body dryer is behind the bumper on that side.
BATTERY AND AIR BOX FITMENT
If the battery tray is cut loose and turned sideways there is enough room to install the n body air cleaner and fuse panel/ junction box.
on the exhaust , use the grand am down pipe(with cat), the cav 02 sensor will work in there if needed, take the rear bolt flange and grind the alignment lip off of the gasket surface. replace the gasket and bolt the cav flange to the grand am down pipe. exhaust done.
Every ones swap will be unique. especially when it comes to the wiring. To help with trouble shooting wiring issues. always solder and heat shrink splices and document any moved wires especially power feeds and grounds. If possible remove the junction ground blocks that are on at least the 2000 and newer ones. use a couple of ring terminals and solder them on. Pay close attention to the one under the battery because this is the first one to go.
01 cav w/01 3400 gam gt 4t45e
I knew Id forgot something.
The listed 50-250 ohm reading is for J's that have the tank sender originally going to the PCM. 00+, maybe 99's.
Not sure on ohm of pre 99's that the sender goes directly to the cluster. they may be the old 0-90 ohm gm senders. However this gauge Is A universal and will work with either senders.
If in doubt just pull your sender out and measure the resistance empty and full with an Ohm meter.

Part # for the N-bod throttle cable:
I needed to get one, can't say for anyone else...
If your using the N body throttle cable you may have to bend the pedal a little because the N cable seems to be just a tad bit shorter. It will work fine though. thats what I used. it will raise the pedal off of the floor if you dont bend it down.
I think there are a couple of different throttle body brackets on 34's so dont be suprised if the n body cable doesnt work.
Some attach with a ball on the end of the cable and others have a barrel, come cable ends are round, some slide from the front.
Mine was a slide in, I bought the cable for the 01 grand am that the engine came from.
I would recommend buying the cable that is for the engine your swapping in, or at least the Throttle body and bracket your using.

Okay, probably a stupid question...but what's the diff' between:
3.1 Euro engine and 3400?
Yes, I'm that completely mechanically-retarded.
Is $250 for running 3.1/3400 a good price?
