Well, I'm not so sure about this....
NA vs Turbo is a very personal thing. It changes the whole character of a car.
Some people swear by Normally Aspirated engines, personally I swear by Turbocharged ones. For me, I cannot seem to beat the feeling of torque building up on a good modified turbo lump. The rush of boost is something i have always loved, been excited by, its a bit like a legal drug (just about legal!). The sheer umph when the boost goes hard, 'full on' is something I reveal in, in a well sorted car this can feel like nos. Its also the easiest type of engine to get excellent power upgrades on for little money. As for turbo lag, well the GT-R shows just how far they've come these days. The fact that most turbo charged engines can ring out another 30-40% more power with just the normal stuff, air filer, exhaust and boost controller just does it for me.
I've always been keen on lower cc engines which weight less and are efficient with high specific outputs. This, normally for the cars I've ever bought (like MR2 Turbo, mid-ship engine layout) and the like, has always meant less weight and better handling capabilities with less inertia from the engines - the big CC engines just remind me of extra weight and compromised ham-strung by the weighty handling. Even with excellent computer controlled handling like on the GT-R your still aware your carrying over 1600 kilos into a corner...
The ideal weight, power for a car for me would be around 1100-1200 kilos with around 400-500 bhp with a 50/50 weight distribution, anything more weighty is too heavy. This is why its now taking 500 bhp and 5 litres for a merc SL to get to 60mph in 5 seconds, too much weight!
The idea of a normally aspirated engine actually put me off buying an NSX because while there was no doubting it felt fast, the performance was just too 'linear' and I wanted more power. I know, I know, that real racing drivers prefer linear because its preditable (no sudden rush of boost sending you off that racing line) but its really excellent to have in-car adjustible boost to suite your driving mood. Its also nice having more power in your car than people think you've got for those supercar scaring moments you get from time to time....
Obviously all my opinions are entirely personal and I am sure there are many more people who love n/a's more...
