I heard they retuned the dampers and some other stuff. The suspension stuff gets me lolI think most of the power increase comes from lower heat at the turbo and better flow through the individual runners as opposed to the single turbo mount on the B58C. Obviously the pistons play a part, etc. but ultimately it's just that it can handle a bit more boost while remaining as reliable as it's predecessor. At least that's my take from the tech details posted earlier. So technically no, mod for mod the newer engine will likely be slightly better all the way up.
And the suspension stuff is adding front strut braces and perhaps a slight spring upgrade. I wouldn't expect more than that or they would have said something more than mentioning the braces in the release.
Important to note however, that tuning the first engine to beyond the capabilities of the transmission is trivial - so you'll still have that very significant "firewall" on either version... you'll just hit it even sooner on the MY21's
So Im guessing they went short runners vs long for the extra Hp āas the tq is negligible. I think they will run about the same mod for mod. Either way I never keep a car over 2 years
