Ford's new 2.3 Litre I-4 Turbocharged Engine and Powertrain was specifically developed to match the new 1979 Mustang/ Capri. This engine/vehicle combination was developed to provide the customer excellent vehicle performance, good fuel economy and driveability.
Extensive vehicle and dynamometer work was done to match the turbocharger to the engine and optimize in-vehicle mid-range to high end performance. The relatively high compression ratio (9.0:1) was retained from the naturally aspirated engine to preserve low end manual transmission vehicle performance before turbocharger boost. Revisions to basic engine components and structures to insure durability will be discussed.
