Stage 1 turbocharger upgrade service. Porsche 993 911 GT2 / Turbo / Turbo S › MD422MD423
- Porsche 993 (911) TURBO 1994-96
- Porsche 993 (911) TURBO S 1994-97
The DesignTek Stage 1 turbocharger upgrade service converts customer-supplied Porsche 993 911 GT2 turbochargers to MD422 & MD423 hybrid specification. No complete replacement turbochargers are included.
How the Service Works
Submit your existing turbochargers for modification. Alternatively, obtain new units independently and arrange their conversion as a separate service; purchasing turbochargers does not include upgrade work.
Fits
- Porsche 993 911 GT2 — application specified for this upgrade service.
- 993 (911) (1994–1998)
- 993 (911) TURBO 1994–96
- 993 (911) TURBO S 1994–97
- Porsche 911 Turbo (993) originally fitted with 5316-970-6736 and 5316-970-6735 turbos.
- Porsche 911 Turbo, engine code M64/60, year &, OEM number 99312301452
Turbo and Turbo S entries describe retained applications, not universal donor-unit suitability for this GT2 conversion. Confirm compatibility of both submitted turbochargers. The M64/60 entry provides no valid application year.
Diagram: 202-16, item 1
What This Product Does
This is a modification service applied to turbochargers supplied by the customer. The specified conversion is MD422 & MD423; it is neither an outright turbocharger pair nor an engine overhaul kit.
Functions
- Converts submitted turbochargers to Stage 1 hybrid specification.
- Accepts existing units or independently purchased new turbochargers, subject to compatibility checks.
Technical Details
- Service specification: Stage 1 hybrid conversion, MD422 & MD423.
- Historical designations MD435 & MD436 are retained for identification only and do not specify this conversion.
- Recorded turbocharger references: 5316-970-6736, 5316-970-6735 and 5316-988-6736.
- Recorded engine code: M64/60.
- Internal assembly information identifies turbocharger 99312301452, note /R.
- Historical output designation: 550-600 bhp. No verified output is established for this GT2 service.
These Hybrid Turbos must be fitted as a pair.
* Please Note: Our hybrid turbochargers require exact engine management settings and/or supporting modifications to achieve these horsepower figures.
The retained horsepower note does not establish an output guarantee for this conversion.
Symptoms of Fault
Investigate unusual whining, exhaust smoke, increased oil consumption, delayed boost delivery or oil leakage before submitting units. These symptoms alone do not establish that turbocharger modification is appropriate.
Why Replacement Matters
An upgrade cannot correct an unresolved mechanical defect. Assess engine condition, oil supply, boost pipework and seals first, and review the engine-management requirements alongside any supporting modifications.
FAQs
Are complete turbochargers included?
No. You supply the units that undergo conversion.
Can newly purchased units be submitted?
Yes, subject to compatibility. Obtain them independently and arrange modification separately.
Which specification is requested?
MD422 & MD423. The historical MD435 & MD436 designations do not define this service.
Before ordering, confirm suitability against your vehicle's model, production year and engine specification.

DesignTek Porsche intercoolers produces high-flow rate and dramatic temperature reduction which are mainly contributed by two key factors. Firstly, the great temperature reduction is accomplished by a 40% larger than stock sized intercooler cores in which each core has the capacity flow rate of 750 CFM. Secondly, which in our opinion is the most important element of an IC; the inlet/outlet end-tanks. Our end-tanks are a one piece cast aluminium construction design, formed with little to no corners and are also fully polished on the insides to increase air velocity; therefore minimizes welding points and greatly increases air flow and reduction in pressure drop which yields to improved efficiency. Also please note that all of our intercoolers come only in high polished finished for that uncompromised appearance.

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
• Proven TheTurboEngineers quality
• Single parts finely balanced then components assembled and core high-speed VSR balanced
• Supplied with a balance test result document
• Made in Germany
