    My car was 2,450 last time I weighed it. That's an '87 chassis with euro bumpers/spoilers, full cloth interior, 3/4 trunk tar removed (still a bit back there), removed trans tunnel insulation, no A/C, no P/S, no glovebox handle, no radio/antenna, and an S52B32 with an M42 radiator.

    I posted up a thread with more info from the night I corner-weighed it, if you are interested.

      That's so sick that swapping in a chevy v8 will save weight. Not to mention the hp and torque!

          i was wondering the same. i hear an ls1 weighs about 400lbs, which is heavier than most bmw motors. maybe he has something really heavy in there now. 2200lbs is a light e30 though...

            It's going to be close and if I loose weight, it won't be much. The LS motor/trans is a little heavier than my S52/trans based on internet numbers but, I've got a few weight reduction plans for the accessories. I didn't have time to actually weigh my motor/trans/drive line before installing it in it's new home so I'll have to rely on total car weight to see the difference. One thing certain, the weight that is there now is better distributed (lower and further back) so even if total weight stays about the same it will be an improvement. I should have the car back together in a couple weeks and I'll see what the scales say then. :D

              Hi Bob

              Is that possible that official weights of the LS1 motor include the accessories, such as the power steering pump, air conditionning pumps, etc?

              BTW (sorry for the OT) I shipped your subframe mounts last Tuesday or Wednesday. Some guys have started receiving them. First batch has been made with caps slightly loose in the subframe tubes to overcome the possible lack of consistency in chassis and subframes. After the first installs, I may go to press fitted caps if I prove to have been wrongly assuming that BMW ain't capable of making two chassis or subframes perfectly identical... ;-0
              Brake harder. Go faster. No shit.

                Here's some weights from a couple of E30's, starting with the 1991 318is we built for STS autocross class/NASA Time Trials. The new owner has added a 4-point Kirk Racing competition roll bar (60 lbs) but lighter wheels. It has a custom/lightweight exhaust, 2 aluminum racing seats (15 lbs each), and a lightweight battery (Odyssey PC680). The SCCA ST class (renamed last year) has fairly restrictive rules so this car has full interior, air con, catalysts and emissions equipment, and all of the stock glass and sheet metal.



                Here's the M20 powered 1986 325e we're using for our $2010 GRM Challenge entry:


                1986 325e, 5-spd, lightweight battery = 2436 lbs

                This weight above was as purchased, running, except with a lightweight (14lbs) battery we added to get it running. We later yanked the stock bumpers, rear exhaust and some more little junk and got it down to 2359 before we pulled the M20 for a V8 - still running and driving. The hood (39 lbs) and hinge (5.1 lbs) are a little porky, so we're looking at alternatives - but we're massively budget constrained by this Challenge.

                Let's look at some hard data...


                M42 and Getrag 5-spd = 427 lbs. The Getrag is 68 lbs


                Aluminum 5.7L LS1 and T56, with all accessories, wiring harness, and ECM is 609 lbs

                I haven't weighed the M20 that came out of our E30, but I will try to later this week. M50s are pretty heavy (400+ lbs range), but I need to see one on the scales and with a picture before I believe any internet data. :D

                The LS1/LS6/LS7 has a lightweight aluminum block (109 lbs for the LS/LS6), especially for a V8. An assembled 5.7L LS1/LS6 motor with accessories weighs 457 lbs. There's more weight to lose from these, namely in the dual mass flywheel (50 lbs stock) by going to an aftermarket aluminum unit (12 lbs). This weight also includes the a/c condenser, which is usually not used in swaps or race cars. We get them down to 420 lbs, in the car, full of fluids and running.

                We hope to have our E30 V8 around 2300 lbs when finished, but we're not using an LS1. We are using a much lighter Borg Warner T5 behind our V8, which is only 73 lbs. I'll post more data, including the final chassis weight, once we've revealed the engine we're using.

                  Thanks for the data....looks like mine needs re weighing!!
                  Does the first 318is still run an M42?
                  Can I guess the V8 you are using is the Toyota 1zufe???

                    Fair, it is nice to see you post on the GRM challenge car on this side of the planet. Good luck and do make your updates available here as well.

                      The 1991 318is we built and raced for a bit, that a local buddy now owns, does still have the M42. He's campaigning it this year in SCCA ST for auto-x and NASA TTE for track events. It was down to 2338 lbs before he added the 4-point roll bar:

                      Maaaaybe. Or maybe not. The team has a gag order on me about further engine discussions until we get it running. I can tell you this much - I spent all of last weekend fabbing up the motor ans trans mounts, and just moments ago figured out the wacky bellhousing combination needed to run the trans we can afford behind the V8 we're using. :D

                      I figured I'd piss off too many E30 fans posting our $2010 GRM project on here. We ruffled so many feathers on Bimmerforums that they finally created an "Engine Coversion" subforum there, where I duscuss our E36 LS1 swap kits/projects and this E30 V8 project. What subforum here would I even post about this in? The "project forum" under the "member's rides" forum?

                      Please PM me with any forum location ideas - we don't need to crap-up this thread any further about our V8 E30 project. ;)

                        However you take it somebody is going to be upset. Purist will be but people who appreciate ingenuity will not be. Ask Lee. Some still wonder why you need to upgrade "BMW" brakes. As I said nice work; somebody will be motivated by it.

                          Well, I was wrong - we had already weighed the old M20, it just took some digging on our photo gallery site (which has 30,000 images) to find the picture.



                          If you subtract the weight of the 5-spd (about 68 pounds - we've weighed several) that puts the M20 at 429 pounds. The M50 is roughly the same weight, but I'll weigh one some day and post it up.

                          The LS1 + T56 weight posted above (609 lbs) is with the heavy 50 pound steel dual mass flywheel. A super common upgrade to these is to ditch that and use a 12 pound aluminum flywheel (its cheap and causes no added NVH or driving issues). That puts it at 569 lbs. Ditch the a/c compressor (which we usually do) and its approaching ~540 lbs. The weight killer in this combination is the T56, which itself weighs in excess of 130 pounds. Its a HUGE transmission. We've seen Borg Warner T5's used behind LS1s in lightweight applications and they only weigh 73 lbs.



                          So with the T5 and an LS1 you're around ~485-490 lbs, which is slightly less than an M20 and Getrag.

                          Cheers,

                            When are you going to spill the beans on the powerplant?

                            As time went on, the factory developed the car each year, making it faster, more comfortable, and capable of handling at higher speeds.
                            You don’t want this. You want the trickiest, most dangerous, oldest model you can find. Only then can you prove to the world that you’re a man.
