I have been looking thru the schematics of the 840 (1994my) and I couldn't see anything that relied solely on the driver side battery. So I removed it, and the grounding strap and brackets.

Drove the car around for about 50 miles, checked every single feature.. heated seats, sunroof, windows, power seats, a/c, heater, cruise control, headlights, foglights, wipers.. anything I could see that had a switch and it all functions properly. Car starts without a hiccup and idles and runs great.

Just saved myself 46lbs of battery and wiring weight, and added a hidden toolbox location for my small car toolkit I always carry with me.

So far up (down) to 170lbs of weight saving, next week if my seats come in, will be up to 379lbs of weight saving when that's all said and done, along with some sound deadener removal and misc other pieces and a lightweight primary battery.

My goal is 500lbs, while keeping a mostly stock/daily driver looking interior, but we'll see how that goes as I run out of hidden things to remove and replace them with. The real weight saving will have to wait til I get a new daily driver so I can really strip her down for some real re-wiring.

Anyone else have any adventures in this direction?

LOL Not bad not bad at all, second person here to do this take a wild guess who was the first.
Get ready for a minor flaming.... i already caught the real one.
It is the young guys turn to take there E31 to a differnt level all within keeping the style of the car of course.
Car feels a lil differnt doesnt it?Wait till you change seats completely differnt car.
I went to a smaller spare size (same diameter), a single battery that was 25LBS.
The only thing you have to be carefull of is if you have one of those cars with a heavy battery drain, Solve that problem and you are gold.
Under the seats there is some relays and a module i think it controls or links the electric mirrors and steering memory along with the seat sensors that tell you your seat is not fully reclined, Thoses are the only issues you should have cause i did .
Happy Trails Congrats on having the NUTS to make this change not many others do but will give you sh.t anyway.
Your next project should be the 6SPEED ...lol That would be the S

Well, hopefully you're balancing both sides equally. :cool

Just don't park for like two weeks without starting.

You might get away with it down south, since your temperature never gets too low but up here north it is another story.

First one to put a E31 on a weight loss program????

Dinan, years ago did a E31 "lightweight" got it down to +/-3800 lbs. Seats and battery are only scratching the surface. Carbon fibre trunk lid, rear valance, hood and front air dam, manual seats, etc. With all the interior finishing out, the sheet metal looked like Swiss Cheese! Holes everywhere. No power windows, sunroof gone.

This was probably done before most of the "young guys" on this forum were out of diapers! Not that young guys can't come up with innovative ideas, (there is always some rock that hasn't been turned over and some of us old guys have learned that some rocks are just not worth turning over) but they should do research first to find out what has been done before claiming innovation.

No flames, just basics facts that we all have to deal with!

Is this for fuel efficiency or dynamics? Weight balance is key. What is next? Put a light weight E36 motor to offset the less weight in the back? Keep us posted.

alu block z3 2.8L, offset the weight loss from the 50-60lb lighter block with some boost and you'll have a nice broad curve with more power/torque than the m60/70 :)

most of the weight gain would probably be in the gearbox! those suckers are light

You want weight saving? What about this?

1991 BMW 850i race prepped by Nieminen Racing. Weight: 1127 kg (2484 lbs). This was a little more than just removing the battery and seats. There's very little E31 left in that car.

isn't that the car with the turbo 6 cyl? :)

Yep, although they were prepping a new engine for this season. Not sure how far they are with that. Harry might know more about it.

Anyway, if you are looking for an 850 "CSL", this is the closest you can get. Personally I don't see the point in replacing the seats, remove one battery or replace the hood with a carbon fibre one... The weight savings will be so little, it's almost impossible you'll gain a noticable improvement in handling.

it might be interesting to buy a totaled 850 just to systematically break it down to see where the weight is distributed.

FWIW I believe that the sunroof cassette is 60-70lbs, a good place to drop weight if you're feeling motivated.

That kinda was my point, the E31 is a E31, nothing more, nothing less. Trying to make it something else has been done--but after--it wasn't an E31. maybe looked like it but it isn't/wasn't a E31 after all. I agree, seats, battery, carbon fibre--in the grand scheme of things is nothing! Dinan found that out, they only did ONE!

There are so many heavy ingredients that make up the vary nature of the E31 that it is impossible to change its personality by simple measures. if you do, it will be by major measures and it will loose its character.

Enjoy it for what it is!

I only wish that one would do an actual "weigh-in" before and after-kinda like doing a dyno run B & A engine mods. Too many phrase like "I believe changing the seats saved me over xxx pounds" and "I'll bet that part xyz weighs a hundred pounds" and suddenly we've got over 800 pounds saved.
Case in point: Everyone used to talk about how heavy the sunroof is (just the SR, not the whole mechanism-don't want to be vague or inflate any numbers here :)) - When I did my CF version it saved a grand total of 8 pounds as the roof only weighed 15 pounds to begin with...

Not flaming at all - heck, mod the crap out of your cars if that's what floats your boat. It just seems that weight savings becomes like adding hp ("I chipped the car, honed the manifolds, changed the exhaust, dropped the cats-and now I'm up to 400hp") - Just looking for hard data, not just someone adding up the perceived savings.
Our cars are kinda like the proverbial "big-boned" girl. She can dress up, got the gym, wear the right makeup and look completely hot - but when she steps on the scale she's still the same as before...

I did rockytt for the seats and batterys only.
The seats he is going to use are differnt than mine i used M3 LUX seats
Batterys are 50Lbs each depending on the type of seats you get for droping that weight
Since i have a 25Lbs battery thats 75Lbs

Yup - I remember - (and please remember that I'm not flaming/attacking here)

What I'd really like to see is something like this:
When I the project started, I weighed the car with a full tank of fuel and it was 4418 pounds. After completing my project (feel free to list all the mods and calculated savings here) I weighed the car on the same scale with a full tank of fuel and she weighed 3715 pounds-

My only point being that "calculated" weight savings and "actual" (just like hp) can be two different numbers. The "oh yeah, I removed the sunroof and that thing weighs like 150 pounds" isn't accurate (not directed at you, btw). Someone removes the sunroof and cartridge and then welds in a new panel to cover the old sliding one and the actual savings is closer to 38 pounds when it's all said and done. "I pulled those front seats out and they're like 100 pounds each and I replaced them with e36 vaders and saved 150 pounds there" is also false-as you and I both know from experience.
Calculated and actual are usually very different animals is all...

oh i know i been meaning to drive down to the scales to get a new weight on my car just havent done it yet.
I know from now on Ill call my E31 Granola 8.
If you need pics i have i did weigh these things

My numbers are precise. Nothing is an estimate. Parts were either weighed by myself or used figures from BMW itself.

And to those who say a little weight saving here and there wont make a difference, when you remove 400+lbs from a car, its like the difference between having two fat kids in the back seat of your e36 while taking it on an auto-x, or not. Seriously, go try it sometime.

400lbs is 10%. That's no small change.

6 speeds in the 840 have been done here in the USA already,
Very well said. :alright

Manual swap. The 5hp-30 is a 240 pound beast. Torque converter is another 35 pounds. I swapped to manual in my 5 series and dropped a minimum of 150 pounds + the extra enjoyment of having a manual transmission.

:rolleyes sorry, but ever swapped it at an 8? It ain´t only a mechanical prob...

The 6 speed behind the V-12 is very big and HEAVY, yes I have swapped a few and shipped a few. Dry the 6 speed weighs about 148 lbs, add a 40 lb flywheel and then clutch pack you are over 200 lbs. Other contributors are the slave cylinder, throw out bearing, clutch peddle etc. 4 speed auto is about a wash as compared with the 6 peed manual.

The V-8 6 speed manual trans is quite a bit lighter/smaller then the V-12 6 speed but the flywheel is a "dual mass" flywheel and is very heavy. The 5HP auto is heavier then the 4HP auto, but depends on which model 5 HP.

:rolleyes sorry, but ever swapped it at an 8? It ain´t only a mechanical prob...

the associated 5 speed to the V8 is actually significantly lighter, can't give you numbers, but I can lift to install the manual and can't get anywhere near that with the auto :)
Also I'd imagine most people doing the A->M swap will be ditching the dual mass flywheel..

swapping the tranny in the 8 isn't much different than an e34, OEM parts and a recode of the computers is the most it would take

edit: I also wanted to add a link to this blog which dropped off some months ago http://850csl.blogspot.com/ there are a few items accounted for with weigh-ins included

Actually the clutch/brake peddle box with peddles is the same part number between the E34 and E31.

Err, the curb weight of the 2005 645ci is 3792, the curb weight of an 840ci is 4130. Which is a slightly bit more then what my target weight is.

The 645ci has an engine that makes more hp down lower(330hp @6100, 330trq@3100rpm), gets same avg. mpg(16-18avg), and does 0-60 in 5.9 seconds. The 840ci (base model vs base model) does the same jog in 7.5 seconds.

Well, first off, it is always impressive when members contribute information and take one for the team, although not all members are willing to follow behind because of the money and advantages to disadvantages involved. Nobody on this thread is cockwaving their $10,000 Ferrari's;), their just people who have a love and passion for this car, they are proud of their 8, just like I will be when I get mine. We leave the cockwaving to the M3 owners, and yes, starting with the E36 owners:D

No one here has really dabled with trying to reduce weight because the question you ask yourself is "What else can I remove to lighten my E31?" Other than lightweight batteries, carbon fiber sunroofs, carbon fiber hoods, and light wheels, there really isn't anything else that can be made lighter. Once again, most will say, if you want the characteristics of an M3, buy one. Owners of these cars know that they are not made to be quick, their made to cruise the Autobahn. Now, I'm sure everyone bought their E31's because they liked the individual looks, luxury and size, and of course the performance on the highway or at higher speeds. Most did not have the reasons of getting this car to track it or take it to the quarter mile, because taking out seats and adding (nonexistant) full CF body panels is the only way you would be able to reduce weight to where you absolutely know its lighter and by a huge margine.

Everyone has their right to voice what they think and know, and they are just trying to tell you that not much of an improvement can be made by trying to lighten the 8 series. You'd be better off buying performance parts for the engine because lightning this car can get expensive and you waist money that could have made a difference you could feel.

g/l with your project.

adding more power won't help you move all that inertia around tight(ish) corners

I think that there are gains to be had by pushing the envelope of tire sizes, if anywhere.
Some firmer springs and/or sway bars in combination with 275 width tires up front would leave me much more satisfied.

I'm a proponent of fitting the widest tires that you can reasonably fit, then adjusting the suspension components as necessary until they match.

That kinda was my point, the E31 is a E31, nothing more, nothing less.

For what it's worth, I did the swap when I was 18 :stickoutt It's not too difficult.

I used the drivetrain out of a 530i(m60b30 trans bolts right up), m60b30 flywheel and stage 2 clutch(the 3.0 liter components rev much faster than the 4.0L) and a modified OEM driveshaft mated to a 530i driveshaft pushing the stock 2.81 differential. I only had to do 1 jumper wire from the fuse box for the car to start. It took a month to do the job. About a week of real work and about 3 weeks of waiting on parts.

Not bad really. It was worth it because I have a love affair with my car. If something ever happens to it, I will swap the drivetrain into an e31.


BTW, here is an acceleration vid with stock chip, open 2.81, freeflow exhaust, and K&N. God it's good to shift gears!!

In the meantime I concentrate more on pleasure :)

Although there´s a new project within reach...

Just figured I'd update, I installed the sparcos, waiting on the seatbelt harnesses tomorrow. Replaced both batteries with a single Odyssey lightweight battery and it works like a champ.

Heres the breakdown so far...(all numbers in lbs)

Stock seat+bracket -165
Stock batteries removal -086
Stock mufflers removed -052
Stock resonator removed -024
Stock cats and downpipes -051
-------------------------------------
-378

Sparco torinos and corbeau belts +76
Odyssey battery +26
Dual hooker mufflers+pipes +30
Magnaflow muffler/resonator +11
Magnaflow cats +10
--------------------------------------
+153

Net change to date = -225lbs

Pics and vids coming next sunday or shortly thereafter when the car is dropped on H&R's and after I swap in my new 3.65lsd.


The project continues...

Keep going I want too see it all!!!
noticed any pep in its step?

What wheels are you using? A lightweight 16"?

What wheels are you using? A lightweight 16"?

I'm using 19x8.5 19x10 LM-R Rep's at the moment. Got them before the lightweight bug bit me. I'm debating selling them. They just look so correct on the vehicle its hard to part with them.

Though I've been looking at 17x8.5 OZ Alleggerita HLT's as the main option for wheels if I do change my mind. They are 17.1lbs each and could fit a 255/40/17 all the way around.

Have you looked on the tire rack?
They have a few good staggered wheels i got mine from them

OEM M Parallels ring in a hair under 20lbs if memory serves, great lightweight, low cost, big tire solution

smokum, you have the AR1's correct? Those wheels are known to be on the heavier side

Well, I figured since I was messing around today might as well update this as its been a while

One caveat: I am assuming the published curb weight, though the other weights are either weights I weighed personally or took from reliable sources (ETK), when I get to the track one of these days I'll get a final weigh in.

Also, project "lightweight driver" is going well too.. started this year out at 240lbs.. down to 207 as of this weeks weigh in! :D

http://i520.photobucket.com/albums/w324/nukeduster/weight-loss.gif

I think I'm getting close to the limit of what I am going to do with the car. I was planning on pulling the stock carpet and replacing it with lightweight carpet, and relocating the battery as this would save an appx. additional 50lbs or so. Also have to pull the automatic transmission oil cooler and lines and weigh those out though its only a few lbs.

Interesting reading there Nuke, but I don't see the difference in the Getrag 420g vs the auto and attendant parts to make'm work, that should be significant. Also, you need to factor in the lighter wallet weight from this project....... :stickoutt

Could you post a couple of pictures of you interior showing the Vader seats. I was thinking of doing it myself. Not to save any weight. To me they just look better. Rick

The M3 Lux seats look good too seen mine? :)

BTW i get to lean all the way back
O did you notice the car is a lil zippyer?

Dunno what weight savings is but my personal preference for alternate seats wold be the 330i Cabrio ones...... uses a pillared restraint system like ours and look a little more refined for the 8er IMO.

Have'nt seen a picture of anybodies seats yet

Rick-I never put the Vaders in my 8, they're actually from my e36 and just sitting in the garage right now...

Ignore the fact that the car is quite dirty har har

The rear area will eventually be re-carpeted, just waiting until I'm done with removing all the excess wiring and crap that's back there.

Thanks; I sold mine in my M3 before I thought about recovering a pair and using them in my 840. Not sure what would need to be done to get them to fit. Thats why I asked. I would like to know they would fit before I would try and buy another pair. Thanks:) Rick

The 840s and 850s don't share the same 6spd transmission Michael... Getrag s6s 420g vs s6s 560g completely different from bellhousing to diff.Has anyone modified it to use the s6s 560g in a M60 powered car?

No, because there's absolutely no reason to. The 560g was a very specific and limited production transmission, introduced primarily for the E31. With the introduction of the E31 V8 in '94 (keep in mind this was an economic decision because of lagging sales of the V12s) the lower torqued motors could share the same 420g transmission already in use by the late E34 and E39 here in the US (and other models in europe) There would be nothing at all gained except weight to go to all the trouble to modify the 560g to a V8. I mean c'mon.. it bolts right up to the V8 block and for our cars any year can be used because we don't need the triggering ring that the E39s do, so go ahead and put an '02 in.....The best of that driveline is here for the V8s... the modified flywheels that utilize the larger non-SAC 280mm CSI clutch.

Hey carspainc.com, what deck are you using? Did you need to modify anything to fit that in there? Looks good.
