Typically 2-3 week lead time on this turbo.

Supports 215whp and 370w torque with our tuning. 

Instant boost on demand. Say goodbye to turbo lag with the KS3 Turbo.

Finally(!) an honest to goodness, self-contained, "plug and play" upgrade turbo stage 3 for a CBEA and CJAA.

The famous "CR170" turbo.. also known as the "stage 3 turbo" in the parlance of various internet forums, comes as standard equipment on the 170 hp (European spec) common rail Mk6 VW Golf, Jetta, and Beetle. Some consider this to be a minor upgrade for the USA-market CR140 CBEA and CJAA engines. The improvement is realized mostly through better high rpm performance that's brought about by the better breathing turbine wheel and larger compressor inducer. This facilitates airflow improvements compared to the original CR140 turbo. The resulting HP and torque improvements are accompanied by lower EGT.

In the factory Borg Warner trim, the CR170 part number is 53039880207, listed for a PQ35/46 engine. The VW part number is 03L253056C. ETKA shows this as fitting cars with the DPF-equipped 170 hp common rail engine in overseas markets.

While it's possible to use it in CR140 CBEA and CJAA engines as it comes in the Borg Warner box, doing so requires the purchase of very expensive (and illegal) exhaust components along with "special" engine computer changes. This is hardly what we would call plug and play. That's why it's is not listed as fitting any US- market car. Until now. 

The KERMA KS3 ("KERMA Stage 3") turbo is the first upgrade turbo ever offered for the US Market CR140 cars that's 100% compatible. This Kerma KS3 turbo retains all factory emissions controls, for an honest to goodness "plug and play" solution that actually IS "plug and play"! No other changes are required... installs perfectly with 100% factory piping and all factory emissions controls in place, for a "no brainer" fit and seamless integration. Our custom version of this turbo with new areo billet compressor wheel configures it for use in any CBEA or CJAA without compromising the integrity of the factory installation. If you need an upgraded stage 3 turbo for your US/ North American-market common rail CBEA/CJAA car, this is the one!


It will even work with the original factory ECU programming, with zero problems, making it a viable upgrade replacement for the original equipment turbo. To attain the full potential of this turbo, a Kerma ECU tune is suggested. 

We require a refundable core deposit to ensure your stock turbo is returned to us. The core deposit is automatically added to the shopping cart. Conversely, you can send in your core in advance to avoid the core deposit.

For a limited time, we will offer further discounts if you can supply additional factory turbo cores, please contact Sales for details at 877-537-6283.
