    That makes me a little depressed

    I have no interior but
    dash, 1 race seat (19lbs), power windows, power locks, sunroof fixed (no track or motor) and cage

    No AC
    No speakers/stereo/wiring
    No cat but a decent muffler
    I have the 6 Speed
    I have PS


    I am really hoping for 2500lbs it would absolutely make my day/week/year if I hit that mark

      So your E30 is a solid 3k lbs wet with you in it? A cage can ad a lot of weight though, my rough uneducated estimate is on the order of 100 lbs.

      I weighed in my 318is (with the M42 in it) at 2560 lbs iirc at a junk yard with me in it, a nearly complete interior w/ stock seats, and full sound system including 8" sub and amp. I weigh ~160 lbs, I suspect my complete sound system weighed at least another 50 lbs or so when you add it all up, and I may have removed ~50 lbs of interior since then as well.

      Keep in mind I had no AC or PS when I weighed it.

      EDIT: re-read some of your above posts. If you have since removed your interior, stereo, AC, cat, You can't still be at 3k lbs. That is an extremely high number. the heaviest stock E30 is at ~2800 lbs iirc.

        Hopefully in the next 2-3 weeks I will be able to put it on some corner balance scales and see what she weighs.

        All the speculation in the world is only that, speculation and the scale never lies.

          Yeah put it on the ACCURATE race scales and post the results. Mine was EXACTLY 2500lbs with half a tank of gas with full interior and m30b35 swap.

            My m20 87 325is track car, with a fully gutted interior (just a 10lb seat and dash/cluster/hvac), 4 point roll bar, removed sound deadening, and no a/c, 1/2 tank, was 2410 verified on Longacre scales (55f/45r, 50.1% cross).

            Jean, I'm surprised by that number. My m50 car with no a/c, no sound deadening, otherwise stock, 1/2 tank, was 2820. Carpet, seats, door panels, etc... really add up. Each seat is what, 30 lbs? Carpet must be a good 40 lbs...

              I just returned from a race weekend, and went across the scales at about 2500lbs, with somewhere between 10-12 gallons of fuel in the vehicle, and a 210lb driver. Our car is *very* stripped, with fiberglass hood/decklid/fenders, gutted bumpers, custom wiring harness (zero OEM wiring), polycarbonate rear/side windows, removed sunroof cassette, no headlights, door glass, sound deadening, etc.

              FWIW,

                ^^ there ya go, battle cattle!

                And Jean, an M30B35 is definitely much heavier than an M60, so that number makes me happy.

                  This was done at a local race shop on corner weight scales. I can tell you exact configuration:

                  84 318i chassis with euro bumpers/valances
                  full interior but with corbeau trs front two seats, stock rear seat (cloth)
                  stock carpet and door panels, manual windows, manual sunroof
                  car has no trunk tar, no tar under the rear seat either
                  no spare tire, no jack, no a/c compressor.
                  stock headliner, this was on 15x8 trm wheels
                  half a tank of gas, magnaflow exhaust/cat.

                  tipped the 4 scales at exactly 250X

                    I've weighted the original m10 and then m30+tranny, I will do the same with m6x. I already did weight the dry e39 6speed tranny it was about 110-110lbs. I think I did weight the m62tu but that was with the 30lb flywheel and the water cooled alternator/vanos and all that which isn't exactly apples to apples..

                      This was with the M30B35 swap, yes? Also, did you only remove the AC compressor, or the rest of the AC components? the condenser/fan is a pretty significant amount of mass.

                      That's a pretty tight measurement tolerance you got there.

                        Haha, I meant 100-110 dry. Sorry.

                        Car had no AC compressor, no AC lines, rest was there. I was using the condensor as the electrical fan mount until later.

                          Well, E30 has suspension geometry from the '80s, whereas E46 is almost 20 years younger. It makes huge difference when starting from standstill.

                          e.g. when racing from 100 to 200 km/h M60 powered E30 will win, but from 0 to 100 it'll lose (depending on drivers, suspension etc etc). But you get the point :)

I'm guessing my m60 car will be about 13.5@103 with a typical 2.2 60' (I suck). Depends on weight, track, driver, gearing, etc... but if an e34 540i/6 can run low 14's at ~100, there's no reason a 500lb lighter e30 won't be considerably faster.

                          Well, go and try out. So far the best 1/4 mile E30 M60 time slip I've seen is around 13.75 ...


                          Also, JGood, I believe an E30 at ~2500 lbs is more like 1000lb lighter than an E34 540i. Wikipedia puts the E43 curb weight at 3450 lbs. a 1000lb difference is huge.

                          What comes to the weight of the V8 E30 swaps, with full tank and without driver we have measured these;

                          -e30 cabrio v8 6-speed manual; ~3000 lbs
                          -e30 cabrio v8 automat, ac, el seats etc..; 3300 lbs

                          These misses are not too light.. Of course having hard-top model with stripped interior etc will reduce weight by what? 200-400lbs?

                          It will, as you'll have to swap driveshaft, brakes, gearbox etc etc.. to larger items. Weight will add up quickly..

                          Actually, numbers look like this;

                          -M30B34 137kg
                          -M60B40 140,5 - 142kg (not sure why the remanufactured engine is over 10kg heavier at 154kg..)

                          Weight distribution will be better with V8 as the weight sits further back than with I6 engine.

                            ^^ That is all very good info there. The E30 cabrio w/ M60 6-speed at 3k lbs seems reasonable, and like you said, a regular E30 will weigh less without the convertible top, and I have no backup for this, but I think the ZF 5-speed is lighter than the Getrag 6 speed. Of course I can easily gather this information, as I have both transmissions sitting on the floor of my garage now. The 5-speed is a lot smaller in size, that's for sure.

                              ... or check the weights from ETK.
