Especially compare to a pushrod motor. Many turbo 4 set up weight the same as a Chevy small block V8. Just look at all the latest drift car, they are all running LS swap instead of the old turbo 4 that they all had. And why? Displacement!

Still static mass compared to moving momentum of the extra cylinders. I must admit that a bigger engine with more cylinders gives that smoother drivability well suited for a luxury car though.

Maybe I missed your point, because your opinion was pointless (re: Evo) in the first place?

That's hardly a flat torque curve.
I'll see your 2-liter and raise you another liter.

Here's an N55 with the following mods on a Mustang Dyno:

Compare it to my custom (self) tuned Evo IX w/ intake/exhaust/DP:

My old little 4 banger has more hp and more torque (at almost the same low rpm as well)...

I've been giggling at these torque specs for some turbo engines including BMWs advertising maximum torque at only 1250rpm, a completely unrealistic loading situation that's never going to happen in any sort of situation with the cars unless they're being driven stupidly with manual transmissions, and HOW LONG would it take them to reach full torque at only 1250rpm, a minute??

Okay so lets put both on a Dynapack then, tune to about equal power, hold them at specific RPMs, and then time how long it takes each engine to go from completely unspooled to max torque. Slow roll in 4th gear at about 2000rpm, it'll take my 3.0L a few seconds to get up to full boost. What about a 2.0L? What about a 1.0L all at equal power levels? Then compare with a 6.0L NA with no "lag" or turbo to spool at all.
