I'm a not a big fan really of any one type of racing, though I tend to like Touring cars and WRC. But like others have said, it's apples and oranges we're comparing here. I think part of the allure for NASCAR is the lack of technology. Average Joe Mechanic can understand a lot of the modifications to a standard old GM, Ford, or Mopar pushrod V8, with a carb. Plus, seems like I've heard a few times before, and maybe it's wrong or becoming outdated now, that carbs actually do a better job of atomizing the fuel than injection does. It's just injection is more easily controlled for best milage and less quirky than carbs. A lot of folks don't understand how a DOHC engine works and such, and lets face it, people aren't likely to pay attention to somehting they don't udnerstand.
Also, you can't forget that NASCAR, or stock car racing in general has come a long long way from it's roots. Hot Rod magazine recently had a bunch of pics from throughout the history of it and some pics from the 60's and stuff the cars still had factory dash's with a key hanging from the ignition. It's just since I dunno, mid 70's maybe that they've turned into the cars they are now that only share a body profile with somehting in the showroom. And I hate to say it, but my guess is you're not gonna convert diehard NASCAR fans to touring very easily because a lot of people are still all about Red, White and Blue, Big 3 car racing and don't care to see hopped up german and jap cars buzzing around a road coarse. I dunno, apples to oranges, don't have to like it, but don't have to make it out to be evil either.
