Performance inlet hose kit.

To fit:
Porsche 991 Turbo and Turbo S from 2013 onwards
Fits both generation 1 and 2 models

do88 proudly presents the worlds first high flowing turbo inlet hoses for Porsche 991.1 / 991.2 Turbo. Self developed by do88 in Sweden !

• Much larger overall inner diameter for improved air flow, 31 % higher! (see graph diagram ). The hoses have a 2,5 inch (63mm) inner diameter at the narrowest location.
• Smooth flow transitions.
• Very smooth internal surface for best air flow.
• Excellent thermal properties, the hoses will not absorb heat from the engine.
• The hoses are reinforced with stainless steel wire to eliminate the risk of implosion on high out-takes.

It was a real challenge developing new turbo intake hoses for the 991 Turbo. The lack of space made it really difficult to make a set of hoses that would outflow the stock plastic pipes. We succeeded but in some smaller areas we had to compromise and allow these hoses to have no clearance, so they will push or rub in some non-sensitive areas.

Porsche 911 turbo. This immortal icon. The absolute essence of the motorworld´s cars, the Porsche 911, elevated by ten – applied with turbo charging. Could it get any better for a car enthusiast?

Owning a Porsche implicates more than just owning a car. A Porsche is a Porsche. You find yourself travelling in the true definition of immortality, feeling ever so alive. Owning a Porsche is all about enjoying every single detail there is to it. Everything ought to be as optimised and as refined as possible.

This is where do88 fit in. Our self-developed intake hoses increase air flow with 31 %. We can ensure you the sensation while driving is very different. The improvement in throttle response is immense, making the car feel so much more refined and alert. This upgrade makes it become what it should have been from the start. This is an improvement no test figures can explain, it has to be perceived behind the wheel of a 991 turbo!

The package includes everything for mounting:
• 2 wire-reinforced silicone hoses
• 2 silicone hoses
• 2 breather valves
• 2 CNC machined VTG adapters
• Clamps and Screws

This product is available in 2 options, OEM Porsche turbos or with 51.5mm turbo adapters for cars where the compressor wheel has been replaced, and compressor housing machined larger.

TTE850 VTG upgrade turbocharger for Porsche 991.1 & 991.2 Turbo / Turbo S

Welcome to our TTE850 VTG Stage for the 3.8-litre flat 6 engine. To construct a pair of TTE850 VTG we change the original compressor and employ a far larger and more efficient billet wheel and mill the compressor cover to optimum gap to match the new compressor profile. Still keeping the original turbine but clipping the original blades for greater flow and lower exhaust gas temperatures. We also remove some mass to improve response.

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.

Product Highlights:

• Original BWTS VTG turbocharger as base part
• Very early response
• Billet Milled TTE compressor 6+6 BLADE
• High Flow Clipped Turbine
• Plug and Play installation
• 850PS+ Proven

About Turbo Chargers

Porsche Turbo Chargers

At Design911, we supply a wide range of turbo chargers for Porsche models, helping you maintain, restore and upgrade engine performance for both road and track use.

Why do Porsche Turbo Chargers matter?

Turbochargers are central to how a Porsche turbo engine delivers power, torque and overall responsiveness. Operating under extreme heat and pressure, they depend on precise clearances, good lubrication and correct installation. As they age, internal wear, oil leaks or damage can reduce boost, spoil drivability and, if ignored, risk further engine issues. Keeping the turbo system in good order is key to preserving performance and reliability.

  • Keep your Porsche delivering the performance it was designed for
  • Help protect the engine by addressing worn or failing turbo components
  • Reduce issues such as smoke, noise, or inconsistent boost delivery
  • Support long-term enjoyment, pride of ownership and potential resale value

When should you review or replace your Porsche turbo chargers?

Checking turbochargers regularly helps you spot wear, damage or age-related deterioration before it affects performance or leads to more expensive repairs later on.

  • Existing turbos are worn, noisy, smoking, or no longer making target boost
  • You notice reduced power, slower spool, hesitation or an untidy, oily appearance around the turbo area
  • You are upgrading other engine components and need turbos that can safely support higher boost and airflow
  • You are rebuilding or restoring a Porsche engine and want fresh or refurbished turbochargers for long-term peace of mind

If any of these apply, it is a good time to review your turbo chargers and replace anything that is past its best, so your Porsche stays dependable and enjoyable to drive.
