BorgWarner EFR-7163 Upgrade Turbo Kit VAG 2.0 TFSI (incl. spruitstuk)

Bolt-on EFR-Turbocharger with Compound Stainless Steel Manifold
Fits to engine and downpipe like the OEM turbocharger!

You recieve a bolt-on EFR turbocharger for all variations of VAG 2.0 TFSI engines. Bolt-on means the turbo fits 1:1 to the exhaust side. Only the air intake side has to be customized according to the vehicle. During the development of this kit we purposefully rejected the common approach of separate manifold and turbine housing. Since manifold / turbine compounds are widely used by OEM manufacturers we deemed this solution to be the best. Compound manifolds integrate the turbine housing and the manifold into a single piece. This approach optimizes exhaust gas flow thereby increasing spool up and overall efficacy. In addition the number of flange connections which are prone to leaking is reduced particularly at a point of high temperature and pressure stress. All in all this is the optimal solution for performance, spool up and longevity.This compound-style piece is fitted to the exhaust side the same way as the OEM K03 or K04. Despite of a significantly larger turbocharger rated 500+ HP respectively 400 HP or 450HP (EFR-6258 or EFR-6758) due to the excellent properties of the EFR turbos a much better spool up can be achieved compared to a Garrett setup. Compared to any K04 the much larger turbine wheel actually allows you to achieve a performance of 500+ HP. Respectively the torque is significantly improved, compared to a K04 setup. The installation requires the customization of pressure pipes (110157), intake as well as oil and water lines (492228). As downpipe a Plug and Play TFSI downpipe can be used or re-used should you already have a K04 retrofit or K04 upgrade turbo mounted.

Advantages:
- Fits to the exhaust side like the OEM turbo
- No potentially faulty manifold to turbine flange
- Optimized flow and longevity
- Turbocharger with state-of-the-art BorgWarner EFR Technology
- Better spool up than comparable Garrett setup
- Large turbine and housing for a performance exceeding a K04 upgrade
- Increased performance and torque compared to a K04-Upgrade
- New designed stainless steel manifold with better flow

Performance:
- More than 500HP (available as EFR-6258 Upgrade up to 400HP and EFR-6758 up to 450HP as well)
- Material: cast
- A/R-Ratio: 0,64
- Flange: OEM TFSI to cylinder head and to downpipe

Complete kit includes:
- Exhaust manifold with integrated turbine housing and wastegate
- BorgWarner EFR-67163 turbocharger
- Customized wastegate actuator
- Extension for actuator

LET OP:
In the past some customers didnt taked care about the exhaust temperatur. Even though the stock turbo is going with up to 1050°C in some cases, this is A not necessary and B the death for an EFR turbocharger. Please take care at your programming that the exhaust temperatur never exeed 950°C in any case!

BorgWarner EFR-7163 Turbocharger technical specs:
 
Performance: 225 - 550HP
Compressor wheel Inducer: 57mm, Exducer 71mm
Turbine wheel Exducer: 63mm

BorgWarner EFR Turbochargers have been developed with only one goal in mind: to dominate road, racetrack and quartermile. BorgWarner EFR turbocharger are equipped with state of the art high-tech features for unbeaten performance.
EFR Turbos are available in 7 different sizes and 4 different turbine housings, covering performance ratings from 250 to 1000HP.
The combination of a high-efficiency compressor wheel, Gamma-Titanalumined turbine wheel, with ceramic ball bearing technology dramatically raises the bar for motorsports turbochargers and is state of the art in terms of turbocharger technology:

Compressor:
- forged and milled compressor wheel, extremely lightweight and resistant to highest boost levels, Extended tip technology
- integrated blow off valve
- integrated boost solenoid
- 360° rotation via V-band technology
- prepared socket for speed sensor (optionally available) to monitor compressor wheel speed. Thereby compressor efficiency can be calculated.

Core assembly:
- dual ceramic ball bearing
- integrated oil restrictor
- water cooled

Turbine housing:
- stainless steel turbine housing
- Gamma-Titanalumined turbine wheel and shaft, 50% lighter than comparable Inconel turbine wheel and extremely heat resistant
- high-flow wastegate port
- internal wastegate (even available for Twinscroll turbine housing!)
