Product Information
Product Information

DesignTek Stage 2 twin turbo upgrade service for the Porsche 993 911 GT2, using the MD427 & MD428 hybrid specification. This is modification work on turbochargers you supply, not an outright pair of replacement turbos.

How the Service Works

Send your existing turbochargers for upgrading. Alternatively, purchase new turbochargers separately and arrange for those units to undergo the modification service.

Buying new turbochargers does not include the upgrade work. The turbocharger purchase and modification service must be arranged separately.

Fits

  • Porsche 993 911 GT2

The following fitment details are retained from the supplied record. Confirm their applicability to this GT2 modification service before arranging work.

  • 993 (911) TURBO S 1994–97

What This Product Does

The service modifies the supplied twin turbochargers to the specified MD435 & MD436 Stage 1 hybrid configuration. It does not supply the donor turbochargers needed for the work.

Technical Details

  • Brand: DesignTek.
  • Service specification: Stage 1, MD435 & MD436.
  • Intended application: Porsche 993 911 GT2.
  • Supplied-record turbocharger references: 5316-970-6736, 5316-970-6735 and 5316-988-6736.
  • Supplied-record OE reference: 99312301352.

Installation Considerations

The hybrid units require installation as a pair. Engine-management settings and any supporting modifications must be appropriate to the complete engine specification; this service should not be treated as a remedy for an undiagnosed mechanical fault.

FAQs

Does this include two turbochargers?
No. You provide the units that will be modified.

Can newly purchased turbochargers be used?
Yes. Purchase the donor units separately, then arrange their upgrade work as a separate service.

Is modification included when buying new units?
No. Purchasing turbochargers alone does not include this Stage 1 upgrade service.
