Seriously considering putting an offer on this car, what do you think?

You're dumb. An m30 weighs LESS than an s5x.

I think you will find the US S50 is lighter than the M30B34 or B35.

^that is very true.

look under M50 / M52 for US S50 / 52 weights. S50/2s are just bored versions of M5x, so they'll actually be slightly LIGHTER than the non-M versions.

EURO S50 is heavier. S54 is heavier.

M30 is heavier than US S5x by ~15ish lbs.

M10 = 82kg = 184 lbs
M42 = 100kg = 220 lbs
S14 = 106kg = 233 lbs
M20 = 117kg = 257 lbs
M30 = 143kg = 315 lbs
M50 = 140kg = 308 lbs
S50 = 152kg = 334 lbs

Weighed without ancillaries of course.

You guys DO realize that the S50 weight George posted is for the EURO S50, right? The motor that exactly ZERO parts interchange with the US S50?

The US S50 is a somewhat lighter variant of the M50, which weighs 299lbs compared to the M30's 315lbs. This isn't rocket science guys.

Yes, but it's not as much of a difference as people seem to think. That's all.

Correct, the difference isn't that big, but to keep quoting the S50 as being heavier than the M30 when it very clearly isn't is the definition of forums spreading misinformation.

In terms of weights, US S5x < M30 < Euro S5x. Science.

There is a build thread for this car on either Bimmerfest.com or E30tech.com I cant remember which but it appears to be a solid build. If some one wants the details I am sure it wouldnt be to hard to find on one forum or the other.

If you look at the dyno chart for this car you will notice substantial misfiring on the second half of the run. The whole run should be smooth like the first half. This is common on lowbuck standalone ECUs and is not simple and easy to fix. (the tuner would have fixed it if it was) The fix involves an electronics wizard an oscilloscope and a lot of time if it is fixable at all, or a whole other ECU system plus install plus tuning. Not a cheap one either. Just so you know...
