That guy has a crazy (valvetrain?) noise above 6.5k. I noticed after the raised redline that my M20 made a similar sound above 6.5k, but it stopped after awhile. I wasn't really a fan of that sound, so I was happy.
no 24v sounds like a built M20. they just have different sounds.

After I do the M50 swap on my current E30, I kind of want to pick up a redundant E30 and build up the M20. That's how much I like that motor.
