^^ there ya go, battle cattle!

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

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,

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...

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.

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.

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.

Tell me I will be under that.... I just don't think it will happen. Mine full interior/spare tire/stereo everything was 3000lbs with a full tank of gas. If I can get to 2500 or under, I might pee myself a little.

My E30 at the moment has

1. No interior save one driver's seat and dash
2. No AC
3. No PS
4. Nothing in the trunk
5. No speakers/stereo equipment at all\
6. No cat converter

ok, I am borrowing at cat atm to pass emissions, but my regular exhaust has no cat. I think I am around 2300 lbs or less. Currently my E30 is M20 powered, but hypothetically an M60 + ZF 5-speed doesn't weigh much more than the M20 drivetrain.

That said, I am M60 swapping my E28, not my E30. My E28 is a grey market 520i at 2700 lbs curb weight factory, and I plan on not having AC or cats, but I will be keeping the PS and stereo system. I suspect that car will stay near 2700 lbs. Iwould also venture to guess that the M20B20 weighs MORE than an M20B25, since it is the same block with smaller cylinder bores, so more iron.

You can easily get an e30 with full interior to be 2500lbs or so with M60 under the hood :)

why arent you a fan of these motors? From what i hear and see is reliable 300 hp

They don't thrill me like an old pushrod V8 would. I don't think they're bad but just they're lacking something. The BMW inline sixes are a different story.

I would even venture to say that with proper tire compound, diff, and suspension, you may break into the 12s, especially if you are running a frankenbuild motor w/ ~330bhp.

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.

Exactly...e34s are PIGS... 540i and M5 are the heaviest of the bunch!!! 3500-3800LB!!!! You can easily get an e30 with full interior to be 2500lbs or so with M60 under the hood :) The problem is getting it to hook up....WIIIIDEEE tires.

[FunfGan]

The last car my current engine is in ran high 11's, but that car weighed ~1000lbs more or so, so, assuming my car can get grip, I should at least be low 11's.


Oh. Wait, m60's? Whoops :)

Wow, that seems the same or slower than a S50/S52 swapped e30

It will be faster then 14's. I ran 14.4@96 with my 180whp torqueless m50. Hell I ran a 14.6@94 in my 145whp m20 e30 (2500lb). 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.

[RobertK]

"Stock" E30 V8's with M60 engines make around 13.5 - 14.5 1/4 mile times depending on the suspension and driver. So that's roughly the scale..
