Stock GTB1756VK turbo with vacuum actuator and welded to a cast manifold suitable for all PD 1.9 & 2.0 TDI engines.
This is an OEM unit as fitted to the 2.7 Audi engine and is far superior to any hybrid on the market in terms of reliability, spool and performance.
GTB turbos runs the later 3rd Generation VNT technology with vastly increased spool and reduced EMP compared to the earlier 1st Gen GT1756 style hybrid turbos.
Maximum safe boost: 2.1 bar/30psi
Power target: ~230bhp
Recommended Supporting Mods
PD150 head bolts with 12.9 tensile must be fitted to prevent the head from lifting at high boost
4 Bar MAP (Boost Pressure) Sensor
You will need a 4 Bar MAP sensor to run this turbo to its full potential. A MAP sensor rated to 4 bar will read 3 bar boost (which is 4 bar absolute pressure!)
You always want headroom when it comes to the sensor so the ECU can see over-boost and correct it should it occur!
4 Bar MAP sensors are available here:
You'll need a good FMIC (Front-Mount Intercooler) without plastic end tanks like many stock intercoolers have making them prone to leaks at higher boost levels. Most side-mount stock intercoolers also heat soak extremely quickly which will limit power significantly.
For the Fabia, Ibiza and Polo platforms the following Airtec intercooler is highly recommended:
Upgrading/de-restricting the exhaust helps reduce engine back pressure and promote better airflow. Minimum 2.25" recommended here
This turbo is suitable with stock injectors and will see them run to their safe limit of ~240bhp.
Please note these are custom built to order and take around 1 week to turnaround.
The standard setup is for a Skoda Fabia/SEAT Ibiza/VW Polo ASZ or BLT 1.9 TDI engine. If your car and/or engine code is different, please get in touch when ordering to let us know.
