That Ford Performance 3.5-liter EcoBoost? It's all new
http://www.roadandtrack.com/car-show...ceits-all-new/
Calling the 3.5-liter EcoBoost V6 that's destined for the new Ford GT and second-generation Raptor pickup a high-output version is a bit disingenuous. Ford basically wiped the slate clean to make it, retaining only the displacement measurement—and, you know, the fact it has six cylinders in a vee configuration fed by turbochargers and direct injection.
It starts with a new block, heads, pistons, and intake, plus bigger turbos. Ford adds a duel-injection system, a combination of port and direct fuel injection, like Subaru uses on the BRZ/FR-S motor. That makes the H.O. 3.5 the first and only EcoBoost engine to use port injection. Ford calls this a second-generation EcoBoost, so maybe that dual-injection scheme will spread to other engines.

And then there's the anti-lag system. It's not a fuel-dumping system like on fire-spitting nutso rally cars, but we're told a lot of work went into the control systems to make sure manifold pressures stay up to keep the turbos spooled. They're not messing around here. The turbos aren't in the valley—a so-called "hot vee" setup like many of the German companies have moved to lately—but the resulting engine is still much more compact than the V8 it replaces.
