GTB2871 ball bearing turbo on tubular manifold
Flagship build

Hybrid turbos, built the hard way

Every AR Performance hybrid turbo is machined, assembled and balanced in-house — not bought in a box. From the fast-spooling GT1752 to the 400bhp+ ball-bearing GTB2871 on our TIG-welded tubular manifold, each unit is built to a spec we'd run on our own cars.

  • Billet compressor wheels & CNC-machined housings
  • Balanced core assemblies on every build
  • Complete manifold packages — genuinely bolt-on
  • Matched injector, clutch and tuning packages available
