TTE420 Upgrade Performance Turbocharger VAG 2.0 TFSI (S3 8P, TTS, ED30, so on)

TTE420 begins as a brand new standard BorgWarner K04-064 turbocharger that we dismantle and then set about upgrading and optimizing as engineers to create our ultimate K04 frame hybrid. TTE420 Turbocharger is great power stage for the 2.0 TFSI range of vehicles while retaining the OE K04 unit for Plug & Play fitment.

Engineered & Enhanced

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 over stock 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.

Equilibrium


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.

I've updated the Spec on TTE420 as we have made a compressor wheel change and moved to TTE 2871X billet wheel.

Advantages :

Lighter
More inducer area
Faster Spool
Higher flow

But have increased price by 100 euro inc vat on both recon and new

Sounds like a big improvement over stock. I'm looking to forge the engine and go for a bigger intercooler before I get the turbo put in.

Don't think the forged internals are needed. As most of the people running the TTE420 turbo are on stock internals including me.

Hmm. I'm looking to go a little over the 420ps mark though. Something closer to 500. Big ic, plasma coils, Uprated Fuel Pump, exhaust intake etc

Deposit of 500 euro extra on return of your old
You mean old 04 cage with new internals or recon internals too?
