Oh really?! That's cool. I was wondering how common that was. 15
years ago we had engines with 2 position hi/lo cam timing, and more
sophisticated stuff seems to be more and more common. My Acura has 50
degrees of infinitely variable timing on the intake and the VTEC big
cam/little cam on the fly switching. And BMW has some even fancier
hardware.

Sweet Car!! What year ya' got? I really kick myself for not getting an
E36 M3 back in the day. All the used ones I've looked at are "rode hard
& put away wet." I'm really looking forward to the 1-series htat's
suppposed to be coming out -- correct wheel drive, killer engines, low nass!

Yeah, that's freakin' crazy!! Remember 1980s turbo engines with like
7:0 compression, "because it has forced induction" hahahha! I think the
new BMW 335 is also 10-something.
