Geo Foradis and his Ford Sierra competes in the Hellenic Drift Championship in Greece. The car was previously powered by a turbocharged Cosworth YB inline-four capable of 630 hp (463 kW). Geo then swapped to a turbocharged Barra inline-six. The Barra motor is destroked from 4.0 liters to 3.6 liters. It uses a billet crankshaft, forged pistons, Carrillo forged rods, and Precision 6870 turbocharger. The motor produces 1060 hp (779 kW) on a Link XtremeX ECU. Behind the motor is a Quicktime bellhousing attached to a Samsonas sequential transmission. From there power is sent to a Winters quick-change rear end with Wisefab axles.

What’s the idea behind destroking?…I’ve heard of it but never really understood why, most people tend to make it bigger for more power
Is it reliability based?…or something like timing?
He destroked it to rev higher and make more power up top. Shorter stroke means less piston speed and stress at high RPM, letting the engine safely spin faster. With a turbo, that extra RPM range helps keep power climbing instead of falling off. You lose some low-end torque, but for a high-horsepower build like this, it’s all about top-end power. I hope that answers your questions
thank you for the article and for the support for more material on insta geoteam19

Is there pleanty of room in the engine bay or did the firewall have to be modified?
