REVO Uprated Turbos

The Revo Turbo upgrade is an unrivalled performance package. Manufactured and designed alongside our technical partners Turbo Technics, this upgrade goes beyond other available hybrid turbo solutions and features a completely re-designed compressor and bearing housing. The increased housing size allows for a larger custom billet compressor and turbine wheel, and most importantly the bearing and shaft size. This allows us to offer a more reliable turbo solution with larger capacity and efficiency over other options utilising the standard compressor housing.

These improvements result in a dynamic package that offers incredible power delivery at high revs, while still maintaining driveability and boost response for ‘around town’ driving lower in the rev range. Revo Stage 3 Software has been specifically developed to work with the Revo Turbo Upgrade, offering greater power gains without compromising on the response.

Turbo Specification

  • CNC machined billet compressor wheel.
  • Increased shaft, wheel and bearing size.
  • Uprated thrust bearing for higher boost capacity.
  • Increased compressor housing size and inlet.
  • Ported wastergate for greater boost control.
  • Enlarged and straightened outlet to improve flow.

Performance REVO alloy wheels.

The 19” cast alloy is a lightweight yet exceptionally strong wheel, designed in-house at Revo HQ and manufactured by OE Manufacturer and Motorsport specialist Rimstock making it a truly British product. Utilising the low pressure casting process used in the production of Rimstock’s tried-and-tested motorsport wheels, we were able to produce a timeless motorsport classic that could perform where it matters most; on the road.

As with all Revo products, performance was a key factor in our design requirements. With an impressive weight of 10kg the RV019 is one of the lightest 19 x 8.5 cast wheels available, offering a huge reduction in unsprung mass over a factory wheel. The 10 spoke design not only looks great but is designed to clear your Revo big brake kit and offer more efficient cooling to the brake system than other wheel designs. On top of the performance and aesthetic qualities our RV019 also comes with full TÜV approval.

With a classic motorsport look featuring an embossed Revo logo and branded centre cap to compliment the subtle styling, the wheel is available in a choice of High Gloss Silver, Black or Matt Anthracite.


  • TÜV approved.
  • Light weight at only 10kg.
  • Made in the UK.
  • 2 year manufacture warranty.
  • Fits Revo big brake kit.
