CTS Turbo K04 Upgrade for FSI TSI Engines

CTS Turbo's K04 upgrade for 2.0T FSI/TSI transverse engines is engineered the right way: the compressor cover and exhaust housing are built to work with the larger K04 CHRA as intended — not a big K04 CHRA dropped into a small factory-spec housing.

Best bang for the buck

Beware K03/K04 builds that do not flow properly for the larger turbine wheel; they can lead to poor performance and premature failure. CTS's high-quality castings are CNC-machined to replace your factory turbo with no extra parts — all you need is an ECU tune and a performance downpipe. With proper tuning and supporting mods, this turbo supports 350HP/360TQ.
