Nortech Performance - VAG EA113 2.0 TSI/TFSI Turbo Kit

Stock to order In stock


This Big Turbo System has been rigorously tested over many months and thousands of miles on a multitude of vehicles and applications. This set-up represents the ultimate advanced turbo solution for the EA113 2.0L engine.

With 400 to 700whp (depending on turbo selection), it delivers savage, yet linear acceleration. But it isn’t just about peak power. The progressive nature of the set-up, together with OEM levels of drivability and refinement is what makes this a genuinely usable package.

PLEASE NOTE: This kit does not include ecu tuning or the turbocharger.

Suitable Applications

- Volkswagen Golf GTI (Mk5)
- Volkswagen Golf R (Mk6)
- Volkswagen Scirocco R (Mk3)
- Audi S3 (8P)
- SEAT Leon Cupra R (1P)



Having identified the integrated turbine housing and manifold as the main restrictions with the otherwise very durable EA113 engine, we set about developing a solution. For those looking to make 400+ bhp, reliably, there really is no substitute for a high-quality tubular manifold with external wastegate.

Although hybrid units are available for the 2.0 TSI, we firmly believe that a big turbo is the better performance option. It was essential that the package delivered more power, but without the high boost levels and associated stress of a hard-worked hybrid. As with any Nortech product, the watchwords are Performance, Drivability and Durability.

Around town the car is refined and civilised, but get it on the open road and it delivers a thrilling driving experience that can worry far more exotic machinery.

To get the most from your Big Turbo kit and to fully utilise the increased performance available, you will require:



- High Flow Intake System
- Performance Intercooler
- Performance 3" / 76.2mm Cat-Back Exhaust System


- Performance Brake Kit
- Performance Suspension Kit
- Limited Slip Differential
- Performance Tyres


The Golf R Mk6 and Audi S3 8P are still some of the best all-round hot hatches available. Straight from the factory, they offer a potent 2.0L EA113 engine, four-wheel drive and are wrapped up in quality packages. This is a great starting platform however, there is so much more potential just waiting to be harnessed.



- Nortech tubular manifold (available on its own)

- Nortech de-cat downpipe & secondary section
- Turbosmart Hypergate 45 external wastegate
- Nortech silicone boost hose
- Silicone inlet hose
- Nortech Hardpipe
- Nortech Heat shield
- All clamps and fittings




The Nortech Performance tubular manifold is beautifully crafted from T304 stainless steel. This robotically TIG-welded component features a unique cast CF8C+ merge collector for ultimate strength and reliability, along with optimised primary dimensions and a an in-house CNC machined Nortech signature head flange. Not only does this bespoke manifold optimise exhaust gas flow, it also looks like a work of art.


Included with the package is a Nortech high-flow de-cat downpipe. Manufactured from T304 stainless steel, including flanges, flexible section and lambda bosses, this robotic TIG-welded component has been specifically designed for use with Garret turbochargers. Please note: this item is designed for off-road use only.


Our STG4 package has been rigorously tested on several Golf 6R development vehicles. We’ve driven them in every real-world situation you’re likely to encounter, from fast country roads, to stop-start town driving and, of course, on track. The car has also been subjected to many hours of dyno development to ensure it meets our stringent demands of performance, drivability and durability.
