I take nothing serious from the engineering and development rumors spawned from Scion. whether it be opinions or reps. Turbo or not turbo.
Any mechanical changes warranted to the Zx6 platform will be decisions from Subaru and Toyota Japan, particularly Mr. Yoda, Mr. Tada, Mr. Mori, and Mr. Tachimori. The real figure heads behind the twins. I only trust words from their mouths in regards to future plans.
