GTB2565VKLR turbo with vacuum actuator and welded to a cast manifold suitable for all PD 1.9 & 2.0 TDI engines.
This is a modified version of the OEM unit as fitted to Audi 3.0 engines 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.
This turbo has ball bearings, custom enlarged and lightened turbine and a race billet compressor wheel.
- Suitable for 400 bhp
- Larger 65mm race compressor wheel
- Custom enlarged GTB25 turbine and shaft - 49/51mm and 33 grams lighter than stock GTB22
- Genuine Garrett Ceramic Ball Bearings
- Dynamically balanced beyond OEM calibration
- VNT actuator and stop screw accurately calibrated
Maximum safe boost: 2.8 bar/40psi
Power target: ~400bhp
|Connection||Plug and Play||Modification Required|
|Boost pipe||No||Silicon connection required|
|Exhaust downpipe||No||GTB flange (included) or v-band must be welded to downpipe (or use a GTB flanged downpipe)|
Included in the kit:
- Turbo charger
- Oil feed line with correct oil restriction
- Oil return line
- Water feed line
- Water return line
- Downpipe flange
Water lines are not required but highly recommended for high load situations like track usage or extended full throttle.
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:
Stock injectors do not flow enough fuel to make the most of what this turbo can offer.
You will want to upgrade to Firad 160% for 400bhp. Check the sizing chart on the link below. You can purchase injectors with nozzles fitted on exchange basis 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:
A camshaft upgrade should be considered to get you from ~270bhp to over 300bhp without requiring excessive boost and heat. We highly recommend the Veicomer 272 degree / 9.8mm camshaft. Available individually or as part of a kit:
The head will need porting to allow the additional air flow from the turbo to the engine.
When fully tuned with big injectors, a Sachs SRE Performance clutch is the only way to be sure the power reaches the road without slippage or removing the box again later due to a failure. These clutch kits are incredibly reliable and with the sintered paddle will hold almost anything you can throw at it.
Upgrading/de-restricting the exhaust helps reduce engine back pressure and promote better airflow. Minimum 2.5" recommended here
High quality turbochargers at good prices takes time to perfect. These are professionally custom built to order and take 5-10 working days for production, balancing, testing and shipping. This can take longer during busy periods. Please get in touch before ordering if your requirement is urgent.
