Full Line of USA-Built Audi 2.7T Upgrades!

Posted by at 27 January, at 19 : 35 PM Print

After 2 years of R&D our complete line of 2.7T twin turbo upgrades for the A6, Allroad, and B5 S4 are available.

Each of the FIVE models (stage 2 has two variants) have been meticulously developed and improved through trial and error with our numerous tuning partners to offer the Audi community four different turbo upgrade options for customers with different goals and objectives. Every model uses Turbo Concepts custom-designed DZX center rotating assemblies featuring:

  • 11-blade advanced aero compressor, for smoother power curve, lower inlet temperatures, and wide efficiency range
  • 9-blade turbine with features that make it lighter for quicker spool and lowers back pressure to allow more power into higher RPMs
  • Low drag stainless bullet shaft nut
  • Upgraded internal components to handle more thrust and enable more oil flow

Read all the pages to find what’s right for you, and if you still have questions our experienced turbo experts are on call from 9-5 EST by telephone or email. Nervous you won’t pick the right one or you might want more power down the road? Got you covered, we offer core rebuild-and-upgrade service to turn your stage 1 into a stage 2 or stage 3, pricing will vary but will be right around half the cost of a new set.
