HPA Motorsports

Price is for a pair (2 x turbo cartridges & replacement compressor covers if ordered)


Upgrade your Audi C7 S6, S7 or D4 A8 to RS7 turbos without having to replace your entire turbo. HPA offers RS7 turbocharger cartridge and compressor housing upgrades to shorten installation time and save money! HPA’s solution is a natural power upgrade to Stage 2+ if your turbochargers are failing.

HPA Audi 4.0T turbo parts are made with the highest quality OEM service parts. That means OEM quality without buying the complete turbocharger from the dealer - an over 50% savings in cost!

HPA’s solution replaces the super core of your OEM turbocharger. The exhaust manifold and turbine housing stay in place during the installation process. This means better priced parts and less labor.

Own a RS7 or S8? This is a direct replacement for your failed OEM turbos!

HPA RS7 Turbo Upgrade Features:

  • Made with the highest quality OEM service parts
  • Bolt-on fit to OEM exhaust manifold/turbine housing
  • CNC machined billet compressor wheel
  • Replacement compressor covers

Extra Maintenance Steps

If your current turbos have been inspected and no problems are found, please note the following minimal repair/inspection requirement from Audi TSB 2044640/4:

  • Check valve and oil strainer should be replaced
  • Ensure the oil bypass valve is fitted correctly

On top of the TSB, HPA recommends to replace the oil separator (PN: 079103542E).

For the ultimate peace of mind, NGP highly recommends that you install the JHM Stainless Braided Turbo Oil Line and Strainer/Screen Relocation Kit. This kit eliminates the faulty factory equipped oil strainer system and replaces it with a much better filtration system. Replacing your OEM Oil Strainer/Screen is a lengthy process which requires the vehicle to be placed into service position and remove the throttle bodies, intercooler, bi-pipes, oil separator, etc. just to get to the screen. With this JHM kit, this job only needs to be performed ONCE, saving you from this costly service every time you want to clean your filters. For your convenience we have added this kit as an option above.

High Performanace Downpipes

If you're interested in getting the most from your new HPA 4.0T Turbocharger upgrade, consider adding some high performance downpipes to your order. These downpipes allow for the installation of Stage 2 ECU tuning, which nets you even more HP and torque.
