Three generations of Ford turbo
Ford's turbocharged performance cars fall into three groups: the Sierra and Escort RS Cosworth, with Garrett turbos on the YB engine; the five-cylinder Focus ST and RS of the late 2000s, with BorgWarner turbos; and the EcoBoost engines that followed.
Ford did not feature in GP Turbos' past listings, so an enquiry starts from the turbo's part number and condition. A turbo rebuild returns a turbo to its original specification; a hybrid keeps the original housings, upgrades the internals and needs a calibration matched to it.
GP Turbos is independent of Ford. Model names are used only to identify which cars a turbo fits.
