- 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.

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.
