PA K04 F23T Turbo for EA113, EA888 Gen1, Gen2 Transverse Engine

We are excited for the official release of our K04 F23T Turbo.

The K04 F23T is a high-performance hybrid turbocharger designed as a direct bolt-on upgrade for transverse VW and Audi 2.0T engines. Available in Stage 2 and Stage 3 versions, it offers a strong increase in power while remaining easy to install.

The Stage 2 version features a billet compressor wheel with a 46mm inducer and 54mm exducer, a 60mm inlet, and a 0.6 A/R compressor housing. It uses a journal bearing cartridge and a turbine wheel measuring 56mm inducer by 50mm exducer with a 0.64 A/R. This configuration is capable of supporting up to 450 horsepower.

The Stage 3 version steps up with a larger billet compressor wheel measuring 53mm inducer and 71mm exducer, while keeping the same 60mm inlet and 0.6 A/R. It uses a ball bearing cartridge for improved response and durability, paired with a turbine wheel of 54mm inducer and 47mm exducer with a 0.64 A/R. This version is rated for up to 550 horsepower.

Both versions use a high-temperature K04-spec turbine housing and are designed for direct fitment on EA113 FSI and EA888 Gen1/Gen2 TSI transverse engines.
