if nissan is thinking of a retro concept,id be inclined to say the value of datsuns will go up in the coming years.

as of the brz, imagine of toyota releasing an mk5 supra.
Japan has been ahead of their times.To think the rb26dett was in production cars by 1989 and the 2jzgte by 1991 makes you wonder the engines will see in the next 20 years or so.

any idea of the engine which has been proposed for this idx concept?
