this is cool as hell. looks factory. its like a factory m3 gtr.... but with a s65. how is the balance? if i remember correctly, this motor weighs slightly less than the I6, but how is it with all the other crap in there it needs to function?

yes weighs less, but the 6 speed out of the E9x weighs more than E46 M3 6 speed because it has an trans cooler system which was retained. So it is a wash. The engine sits low and back, balance is not effected, few issues with added steering links to get around the bank 2/driver side header, but found some things that will help

I've had the good fortune of taking a ride in this car and it's a hoot!! Raw power and very well balanced. Even though is as close to perfection as it gets I know the owner will continue tweaking this beast to no end, well done indeed!

Motec M150, car, drivetrain, Motec, basic stuff to get car running/tuned all in about $50K other mods, like CSL roof, coil overs etc..that is extra of course. Cheaper than a new M2..

The s65 long block (complete engine-- includes heads/cams/vanos/etc) is ~30 lbs heavier than the s54 long block. You can verify this on realoem or any number of people who have weighted both engines, fully dressed. It was a very tricky (to put is nicely) word manipulation by BMW, claiming the s65 V8 was lighter than the s54 I6 :P That said, being 2 cylinders shorter, I wouldn't expect the weight distribution to be meaningfully changed.

I still think that's very impressive: a larger, higher displacement engine with more sophisticated valvetrain + components is only 30 pounds heavier than the one it replaces.
