Product Information
Product Information

DesignTek’s Stage 1 twin turbo upgrade service converts customer-supplied Porsche 993 911 GT2 turbochargers to MD435 & MD436 hybrid specifications. Complete turbochargers are not included.

How the Service Works

Provide your current turbocharger pair for the upgrade work. Alternatively, obtain new turbochargers separately and arrange their modification independently; buying those units does not include this service.

Fits

  • Platform reference: 993 (911) (1994–1998)
  • Model reference: 993 (911) GT2 1994–97
  • Porsche 911 (993) GT2, engine code 993USTGTR2, year 1995-1999, OEM number 99312301382

The platform dates, model dates and detailed turbo application differ. Verify the vehicle identification and fitted turbocharger references before commissioning modification. Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

This is modification work on a supplied pair, rather than an outright turbocharger purchase. The Stage 1 specification involves changes to compressor wheels, matching housing profiles, turbine wheels and sealing components.

Functions

  • Applies MD435 & MD436 hybrid specifications to the supplied units.
  • Adapts compressor covers for the revised wheel profiles.
  • Modifies both turbochargers for paired installation.

Technical Details

  • Stage 1 hybrid references: MD435 & MD436.
  • Modified high-flow compressor wheels and correspondingly reprofiled compressor covers.
  • Modified, lightened exhaust turbine wheels.
  • Motorsport-specification blueprinting and twin piston-ring sealing.
  • Replacement references listed: 5316-970-6736 & 5316-970-6735.
  • Listed engine-output estimate: 600-650 bhp, subject to supporting modifications and suitable engine-management calibration.

These Hybrid Turbos must be fitted as a pair.

The output estimate is not a promise of results from modification alone. The complete engine configuration and its calibration determine the outcome.

Symptoms of Fault

Investigate blue exhaust smoke, unusual whining, rising oil consumption, slow boost build-up or erratic boost delivery before proceeding. Similar behaviour can arise from leaking hoses, restricted lubrication or boost-control faults, so symptoms alone do not establish turbocharger failure.

Why Replacement Matters

An upgrade is not a remedy for an unresolved mechanical problem. Have the existing units assessed and inspect their oil supply, return lines, intake connections and control hardware. Any underlying fault should be corrected, with calibration matched to the finished engine specification.

FAQs

  • Does the service provide a new turbocharger pair?
    No. The work is carried out on units you provide, whether existing or separately purchased.
  • Is modification included when buying new turbochargers?
    No. New-unit purchase and upgrade work are separate arrangements.
  • Is the stated output assured?
    No. The 600-650 bhp figure is an estimate dependent on the engine configuration, supporting hardware and calibration.

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.
