I know Porsche pretty well. I have been to the factory four times.
For nearly 20 years the GT cars have been built on the same line as other 911s. Yes there are some different bits but it certainly isn't correct to say the GT3 engine is 'completely different'. Miller is just making out he has something really special. More accurate to say it is very nearly the same.
For those who unlike Miller are not satisfied by the GT3 experience, I run a 997 GT2 I have had from new in 2008. At that time the most powerful road Porsche ever built, it's 530 turbo powered horses to the rear wheels. Still seriously quick by any standards it does 7.6s to 100mph and 206 for those brave enough. Even today there is no road Porsche with bigger rear tyres. It is a wonderful drive at Goodwood where I take it twice a year.
