MuchBoost D19AA 1.9 JTDM/Multijet hybrid turbo, Alfa Romeo 159 1.9 JTDM, 200–230 hp

A bolt-on MuchBoost hybrid turbo for applications including Alfa Romeo 159 1.9 JTDM, Fiat Grande Punto 1.9 Multijet. This upgrade is built for D19AA 1.9 JTDM/Multijet applications and retains a clean, vehicle-specific installation.

The turbo is based on original Garrett housings. The upgraded compressor and higher-flow turbine sides provide considerably more capacity than the factory unit, while the housings are precision-machined for the new internals.

Depending on the selected version, the manufacturer rates the turbo for approximately 200–230 hp. Final output depends on engine condition, the fuel system, intake, exhaust, cooling and, above all, the ECU calibration.

An upgraded turbo always requires vehicle-specific ECU calibration.
