Not to wander too far off topic, but the only reason I've ever seen reported for Corvettes not using DoD is they don't want a 4 cylinder exhaust note under cruise. The typical Corvette owner doesn't like it, so GM doesn't want to do it. It's not an issue on a car with quiet exhaust, but on the Vette, you'd be able to hear the difference.
That may be true on the LS2... but I can tell you for certain on the LS4... I can't tell a change in exhaust note from 4-8 cylinder mode in my GXP. To be honest... that transition is so seemless... unless I am watching the instant MPG reading, I can't tell if I am running on 4 or 8!
My hat is currently off to whoever designed that... now when it breaks, I will be cussing, but for now... that is waaaay cool....
I think the sound of a R32 sounds pretty exotic. I wouldn't mind having one of those engines in a Fiero.
That might be my next swap if I can find a crashed R32 for a reasonable price. The sound is definitely exotic. Then again, a Jetta 24v VR6 with six speed and some upgraded cams can sound just the same for a lesser price. Dave

Thats would be awesome if you got ahold of a R32 engine. I have rode in a R32 and its a amazing car, I can imagine what it would be like in a Fiero. I like the 24v VR6's too, those have a nice tone to them but everyone that has them around here swears they are rare, so they jack the price up on them. My friend had a 1988 GTI with a Twin Turbo VR6 in it and that thing was nasty, crazy fast and it sounded amazing. I want a old GTI like that.

Here's a lambo cover I am putting together over a 3.4L DOHC motor
I still have some work to do and I have decided to try and carve the center cover out of foam so I can have a mold made. I didn't use the diablo cover because of the sloping upper intake manifold. I have the side cover basically done since these pics were taken.
Go with the 3.4L dohc if you want to get anywhere near v12 sound, chevy just ain't gonna work.

I wonder if they'll have to do something like that for the Tesla Roadster, or Fisker Karma, Venturi Fetish, etc. to slowly wean people off the "engine sound" they're used to growing up.
Would make a great joke gift for Tesla owners..
Although I have to say that I absolutely love the sound of a Tesla Roadster. Kind of like a supercharger whine, without the engine, or a Jet engine wine, without the excess noise..
_____ Note: the above cars mentioned are electric cars that do 0-60mph in 3.9 and under 5.5sec* respectively.
(* IIRC, I don't remember Fisker specs exactly.)
Heard only part of a news article this morning that said there is legislation that may require electric/hybrid vehicles to make noise. They cited that a Prius can only be heard when it's 40% closer to a pedestrian than a normal car. I'm guessing this is to address concerns about blind pedestrians not being able to tell that there is an oncomming car.
If my vehicle has to make noise, I want it to sound like the ice cream truck... really screw with the neighborhood kids.

Most of the Euro exotics are small displacement. A lot of tiny cylinders makes a very distictive whine I dont think you will ever get from a V8. A 6 cylinder engine can sound more like them. My V6 Ferrari kit sounded very much like a real 308 when it was wound up. My V8 car just had too much deep throated rumble. You might play with some kind of fan or turbine blade inserted in the exhaust pipes but i dont know. Good luck
