MuchBoost DT20C 3.0 HDI hybrid turbo set, Citroen C5 II 3.0HDI BiTurbo (300–350 hp)

MuchBoost DT20C 3.0 HDI hybrid turbo set, Citroen C5 II 3.0HDI BiTurbo, 300–350 hp

A bolt-on MuchBoost hybrid turbo set for applications including Citroen C5 II 3.0HDI BiTurbo, Citroen C6 3.0HDI BiTurbo. This upgrade is built for DT20C 3.0 HDI 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 300–350 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.
