TTE420 Upgrade Performance Turbocharger VAG 2.0 TFSI (EA113)
Please note: These are a special order with a dispatch time of 4-6 weeks from date of order.
The formula to making a TTE420 starts with a much larger 2871X TTE billet compressor wheel, chosen because is highly efficient, new generation type with very thin blades, creating an extremely high flow for comparative size, giving a compressor map that's very wide. The Re-Profiled compressor cover is machined to an optimised tolerance to ensure maximum compressor efficiency is given. Also, the intake pipe is ported to give a smooth transition for the incoming air flow. We also fit our TTE CNC K04 silencer delete, we modify the turbo discharge silencer, removing the baffle internals and fitting a new straight through section, removing any restriction and its function as a noise cancelling device, so improving the flow and enhancing the sound.
A key part to driving the large 2871X compressor and in turn making this unit produce the huge power advantage overstock and also our 400 upgrade hybrid, is machining and fitting a far larger BorgWarner K16 curved clipped turbine and shaft, while still keeping the k04 core, this is not so easy to do. This K16 turbine gives much lower back pressure and keeps EGT lower compared to stock K04 turbine or clipped stock.
The clipping of the K16 turbine. Clipping reduces blade area thus increasing gas flow and so reducing backpressure and lowering exhaust gas temperatures, allowing safer higher boost levels. This process also gives a secondary advantage of removing some material, lightening the turbine thus reducing the rotational mass improving moment of inertia. Dyno's have shown a little loss in response vs stock K04 yet huge gains in power and torque.
Special TTE developed in house 360 deg high-performance motorsport journal bearing system is fitted. Durable at high loads with no loss in transient response.
The actuator used is uprated sprung OE unit, fitted with our reinforced clamps for trouble-free operation. This also can also be modified to customer needs and specifications.
Precisely balancing our turbochargers is a key critical factor to become a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers to achieving our balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using our single parts machine, then components are assembled and then the CHRA are dynamically balanced, but this time depending on application at up to 250,000 RPM in multiple planes using our in-house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with serial numbered balance test result document.

BREXIT 2021 EUROPEAN TAXATION CHANGES:
For European Customers prices now displayed in cart once you enter your address will have 20% UK VAT Tax removed, however you will have to pay some form of Duties / VAT prior to delivery of your goods.

Why is postage on bulky items to some countries expensive compared to some other companies ?
For both yours and our safety we use well known couriers such as DPD Local and UPS for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. Shipping small items can be cheap, but items such as bodykits are expensive to ship - we have a very small margin on the postage fees merely to cover packaging. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cant be responsible for.
Not everything on our website is in stock, if you need a part desperately please contact us first to confirm availability before placing your order
