That is excellent info. although I do not have endless money to do any of those modifications. Fun to think about though!
The impression I had from the "e-tune" cars was that they were the european release of the legacy GT, but one step further without going aftermarket. (similar to our impreza group( L, WRX and STI). They were selling a stock exhaust manifold that was set up for the twin turbos, etc. Do we have any British people on this board that might know if I am correct?
