What type of flywheel should be used? Can the 3800 use the same engine mounts as the 3100 or will i have to fabricate them?

Standard HM282 flywheel, machined to fit the 3800 crank pattern.

3800 F body flywheel machined down to the thickness of a 3.1 flywheel
as for mounts if your using a series one, not sure about series 2 get the mounts from a 3.0 grand am from the late 80s or any 91 and older N car with a 90 deg v6 3.0, 3.3 etc series 2 you might be able to pull off the old N car mounts, if not then you have to fab up some of your own
Thanks. Will the manual trans from the 3100 bolt to the 3800 and can i use the original tranny mounts that came with the car or is that a fabrication job.

i think you are confused on the 3100 thing...
you have a 3.1 right? Alot different than a 3100. 3100 is a gen 3 engine.
yes, the 3800 shares the same bellhousing pattern as the '660 so the tranny would work fine. Like was allready stated, use a 3800 Fbody flywheel and have it machined down to the stock thickness of the 3.1 flywheel. If you don't then you'll have rubbing issues with the tranny. Use a clutch made for that tranny, it'll bolt onto the 3800 flywheel fine.
Older grand am 3.3/3.0 mounts would work fine.
What about the wiring harness. Can the original still be used for the interior and the new one be used with the engine?
ok, i just want to make sure i am understanding this properly.
the 3800 will bolt directly to the 3.1 5spd transmission with a machined down flywheel? so i assume this will also hold true for the 3800 supercharged also?
now with the supercharged engine with minor mods, would the 3.1 tranny hold up?
as well, I was told that the ecm of the gtp supercharged 3800 relies heavily on the transmission, would this present much problems as well?
thanks.

the 3800s/c computer is obd2, and unles you have every computer in the entire car hooked to it, the car isnt going to run right. the pcm controlls the automatic tranny and if thats not there, the pcm will run in limp mode (pulls timing and may limit the rpm). realy the only way to run it would be with a full stand alone.
the getrag 5 speed will hold up. guys running turbo 3400s making 350+hp dont have issues.
sure you may be able to get the mount brackewts to make the motor bolt into the car, but you will need to make a custom rear exaust manifold (the 3800 one will point into the steering rack). you will run into a pile of problems like that through the swap. its not an easily done swap. i honestly would put in a lighter 3400 and turbo it. with a stock motor and 10psi you can make 300hp. keep in mind that the 3400 is a bolt in (aside from the front mount bracket, that can be purchased online) and you could do the swap and turbo it for less money than the 3800s/c would be, and make more power.
Thank you for the idea about the 3400 but i already have the supercharged 3800 and i would like to see what it will do in my car. The weight issue is not something I am worried about right now in time I will redo the suspension anyway. Right now I am just trying to figure out what i need and will need to do to get it in and running right. Is there a way to bypass the tranny control?
run a standalone perhaps??? www.diyautotune.com and get a pre-assembled megasquirt?
watch for flying sparks!!!
I'm new to all of this so I might have to explain. A stand alone will run what exactly? Would all of the electronics inside the car still work or would i have to install new gauges?
i beleive its an onboard computer to replace the stock computer that u program urself...how dont ask me im just going by what i think i understand about boost would know more since he has one
a stand alone computer is a computer to controll the engine functions and does not run a stock computer. this would be ideal for your swap so you dont have to intigrate a 3800 computer into the car.
i like the megasquirt myself, ive build 2 of them now (the one in my car as well as in boostNbag's turbo eco swap). they are relitivly simple to use and a very flexible system, you can taylor it to anything. you can read up about it here www.megamanual.com
Thanks, all of you are helping me out alot and it is really appreciated. Is there a limited slip diff that would work with this set up?
I started the swap and there have been alot of problems with it but i think it is going good so far.
You can check out my swap
http://jpc-computers.com/3800z24/. I have mine running on the 2.8 ECM, but do not recomend it. You can get the ECM from a 92ish Buick Regal that has the intire ECM, harness and Fuse box under the hood( there might be other years) I am still working on my swap, but have put in on hold til i get more time to work on it. I am thinking of doing the MegaSquirt myself. I made customn True Dual exhaust for mine, and you will need to make or have someone make you a down pipe.
When i get home, I will find the links I have of other that have done the swap. There are a few.

Checked out your link before and it has helped but there is still more about the swap that i don't know. Like did you use the 2.8 radiator or did you use another. What type of cables were used? What tye of hoses?
You don't have to run a stand alone computer. You need to modify the stock PCM bin ffile to work with the 5-speed. If you want to send me an email I have the ability to tune your PCM to whatever your needs are or you can buy a PowerTuner from Digital Horsepower and do it yourself.
