Please ensure this is the correct turbo for your vehicle, if you are unsure in any way please call our support team on 01924 894171.
The 69mm frame GBT is the largest in the range. This option caters for the larger displacement or higher revving engines requiring greater power outputs. The GBT-69 range is capable of producing engine output from 440-820hp.

The option to now have a ceramic coating on your Owen Developments turbo is one that can increase the thermal efficiency of the turbo meaning an increase to engine performance and reliability. The ceramic coating courtesy of Zircotec applies a 3mm layer around the housing which reduces heat loss and allows protection of vulnerable components near the exhaust.
Studies found that it can reduce exhaust surface temperatures by up to 33% and allowing possible reductions in exhaust temperature of >50 degrees Celsius.
As coating is around £200-250 but with this now standard on Owens turbos you can upgrade for around £100.
The GBT units come with an anodised compressor wheel and compressor backplate as standard. In addition to giving the turbos excellent aesthetic appearance the anodising creates a protective layer on the aluminium that helps prevent oxidisation and increases resistance to scratching and wear.
Water-Cooled or Air-Cooled Bearing Housings.
Water cooling is commonly run through OEM and motorsport turbochargers, to help prevent against heat soak to the bearing system. However, where plumbing restrictions or packaging and weight saving is key there is an option to use an air only cooled bearing housing. GBT turbos specially designed air and oil cooled bearing housing has radial air fins, giving a large surface area. Heat soak is dissipated substantially more than just basic oil-cooling alone. Drawing heat away from the oil, bearing system and rotational assembly parts reduces oil breakdown rates and improves component longevity.
Ported Compressor covers.
Generally Ported shroud compressor covers with anti-surge ports is favoured, especially with larger wheel sizes, as it widens the safe operating zone within the compressor map, increases top end flow and protects against low down surge. The advantage with a non-ported compressor cover is that it is significantly quieter.
All our turbo units except competition units carry a 24-month warranty, or 24,000 miles for petrol, 50,000 miles diesel whichever comes first, this is from the date of invoice, provided that they are fitted in accordance with the manufacturers fitting guidelines and are not fitted to a worn/faulty/contaminated engine. AET Turbos recommend fitting a new oil feed pipe and the use of high quality synthetic/semi-synthetic oil, which should be changed according to manufacturer’s recommendations or every 6,000 miles if no guidance is available. Please see our terms and conditions for further information.
We send fitting instructions with every turbo dispatch.
