Stage 2

Maximum performance at same external dimensions
longer lifetime, at an affordable fixed price
available for almost any turbocharger, up to 40 % more efficiency

If a Maximum of performance should be sheetingable also Plug and Play
A Stage 2 optimization differs to a Stage 1 optimization only in the size of the compressor wheel. That sounds simple enough, but it is quite expensive in reality. In the first step, our experts can find out which wheel dimensions on the one hand fit into the compressor housing, perfectly complementing the other to the housing and turbocharger. Some turbo upgrades are a selection of a possible part, but without much concern for the resulting performance. Since we are able to mill compressor wheels according to our specifications, we can offer the combinations that do the maximum.

The large compressor wheel
In the Stage 2 Optimizing a compressor is selected or customized, that is larger than the standard built wheel. Which size difference arises depends on the feasibility of each turbocharger and can be inquired with us for already developed Stage 2 optimizations. The large compressor wheel is shipped of course state of the art. That is, optimized flow, with a slim hub, optimal number of buckets and Extended Tip Technology.

The compressor housing
To provide the large compressor wheel enough space, the compressor housing is machined consuming process by 5 axis CNC. Contours and gap dimensions are optimized in this context, so that the new, larger air flow rate is also used optimally.

The bearing
As in the case of Stage 1, the turbocharger is replaced during the optimization of the O.S.T. Stage 2 optimizing a special friction bearing, which has a special coating with the highest dry-running properties and bridge the lack of lubrication in eg cold start of the engine. Sometimes there are moments when the turbocharger not yet received the full oil pressure and the bearing is not lubricated sufficiently. This usually caused the gradual damage to the turbocharger over the term . Thanks to the O.S.T. Bearing the normal wear is significantly reduced and extends the life of your turbocharger.

The affordable price
O.S.T. Stage 2 for new turbocharger starting from 690€ (only if Turbo is not listet in our website)
O.S.T. Stage 2 for used turbochargers starting from 990€ +70€ if with VTG*
O.S.T. Stage 2 for racing turbocharger on request

The delivery time
For many turbocharger we can realize a Stage 2 optimization already within 3-6 business days. The special thing about us is that we provide not only for the optimization of best-selling turbos, but can optimize almost any turbocharger on the market. For models for which we still have no components in the offer, the development time is only 4-6 weeks.

What should be considered in the Stage 2 optimization
A Stage 2 optimization developes significant power in contrast to the standard turbocharger. Individual tuning is required in every case. Likewise, further modifications have to be made depending on the vehicle model and engine type.

The advantages of O.S.T. Stage 2
The focus of O.S.T. Stage 2 optimization is clearly on performance. In addition, of course, the lifetime is improved. Whether O.S.T. makes sense for you, you have to decide. If one or more of the following statements apply to you , O.S.T. is right for you.

I want to achieve the highest performance with my turbocharger which is sheetingable plug-n-play
The Stage 2 optimization uses the largest possible compressor wheel while retaining the original exhaust housing and compressor housing. Thus, Plug and Play installation is feasible. In this size is the power output at the upper limit.

Chip Tuning isn't enough for me, I want to set my vehicle individually
The air mass, which is funded at a Stage 2 optimization is much higher than that of the serial turbocharger. A custom engine tuning is required in every case. If you are planning to do so , anyway the Stage 2 is the right choice.

I want to have a durable turbocharger with more life
The O.S.T. Special bearing has a special coating on a special carrier material. Through this combination, the bearing is able to bridge short moments of a lack of lubrication. This lack of lubrication occurs inevitably at every cold start and other situations during the period of engine use. The O.S.T. bearing increases the life of your turbocharger.

What is O.S.T. ?

O.S.T. stands for Optimized Serial Turbochargers. During the optimization, a standard-turbocharger gets a new milled impeller, which optimizes the flow and which is especially lighter. In addition, also a special friction bearing is being installed, which has a special coating with the highest dry-running properties. Thanks to the O.S.T. Optimization your turbocharger gets significantly better performance and longer life.


Upgraded, reinforced bearings
An OEM turbocharger that has a normal 270° or 360° journal bearing, gets with the O.S.T. optimizing a stronger special journal bearing, which has a special coating with the highest dry-running properties and bridges the lack of lubrication in eg cold start of the engine. Sometimes there are moments when the turbocharger not yet received the full oil pressure and the bearing is not lubricated sufficiently. This usually caused the gradual damage to the turbocharger over the term. Thanks to the O.S.T. Bearing the normal wear is significantly reduced and extends the life of your turbocharger.

Stage 1 upgrade CNC milled compressor wheel
With a TurboZentrum O.S.T. Stage 1 hybrid upgrade the turbocharger gets a new CNC mashined compressor wheel. Every Stage 1 features:
  • compressor wheel optimized in the dimensions (height, slim hub and Extended Tip technology)
  • still fits the contour of the OEM housing
  • CRW optimized for more flow
  • CRW lighter than "cast" wheels with the same dimensions
  • CRW machined from forged aluminum
  • More stable and thus more durable at high boost pressure
  • Perfect for engine with ECU Chip tuning
  • "Zero gap" compressor technology
These type of CNC billet compressor wheels are found today in wide range of Motorsport turbochargers (f.e. BorgWarner EFR / SX-E, Garrett G-Series, Precision Turbo, etc.). Normal cast wheels are mostly out of date. The O.S.T. compressor wheels are machined from forged aluminum, are more stable and thus more durable at high boost pressure. So it is perfect for engine ECU Chip tuning. The O.S.T. optimization does not reach the extreme performance of a Stage 2 (larger) compressor wheel, but the response remains at least equal, if not improved, and high performance in a performance-enhanced (eg in chip tuning) engine even better. It is not as extreme as Stage 2 or Stage 3 modifications with larger compressor wheels. With this modification, the response characteristics remains at least equal, if not improved, and the maximum power in the (eg by chip tuning) upgraded engine is even better. The compressor of an O.S.T. Stage 1 turbocharger is up to 15% more efficient!

Stage 2 larger Upgrade milled compressor wheel and CNC mashined housing
The main difference between the TurboZentrum O.S.T. hybrid Upgrade Stage 1 and Stage 2 optimization is to fit a compressor wheel as large and efficient as possible. That may sound easy, but the process is quite complex. First our team figures out, which dimensions work best with your compressor housing. Some of our competitors simply take any compressor wheel which is "laying around" without inspecting the airflow and shape into consideration. Because we are able to CNC mashine every compressor wheel to our exact specification, we can give you the best possible power output. Next, the compressor housing is CNC milled exactly to the dimensions of the new compression wheel combined with a "Zero-Gap" compressor technology. With our Stage 2 you will get the best efficient (up to 40%), maximum air flow and highest horsepower turbocharger output in an OEM plug-and-play package. Every Stage 2 features:
  • Compressor wheel optimized in dimensions (height, slim hub and Extended Tip technology)
  • CNC mashined OEM housing
  • CRW optimized for more flow
  • CRW Lighter than "cast" wheels with the same dimensions
  • CRW machined from forged aluminum
  • More stable and thus more durable at high boost pressure
  • Perfect for upgraded engine with high horsepower
  • "Zero gap" compressor technology
  • *clipped turbine wheel for less back pressure
