This is a bolt on hybrid turbo upgrade for 1.9 & 2.0 TDI engines, suitable for 250+ bhp.
This turbo is best when you're not ready to upgrade other supporting mods, but would like a hybrid turbo upgrade or need a simple replacement.
It's essentially a PD150 turbo with a larger compressor wheel and housing and reinforced bearings for reliability. Fully balanced and actuator precisely calibrated - ready to install.

Alternatives
We also sell 3rd generation VNT Garrett GTB turbos which have improved spool and decreased Exhaust Manifold Pressure (EMP) from an improved VNT mechanism:
Supporting Mods
4 Bar MAP Sensor
A 4 bar MAP sensor will be required to allow the ECU to monitor higher boost levels. The stock MAP sensor for a PD130 is 3 bar absolute (2 bar boost).
Head Bolts
PD150 head bolts are advised to prevent head lift occurring from the higher boost levels this turbo will produce.
Intercooler
An intercooler upgrade is advised - stock intercoolers have plastic end tanks which are prone to leak. They also heat soak extremely quickly beyond stock power levels
Injectors
This turbo is suitable with stock injectors and will see them run to their safe limit of ~230bhp. Firad 50-80% is advised for over 230bhp for extended runs, such as on track.
Exhaust
Upgrading/de-restricting the exhaust helps reduce engine back pressure and promote better airflow. For example, larger diameter exhaust, and catalytic converter removal (for off road use) will improve turbo spool and prevent high back pressure occurring from the additional exhaust produced.
