The Turbo Repair Birmingham


Best Turbos™ an experts are available to help you at any time!

Turbocharger such as Borg Warner VGT (Variable Turbine Technology),

Holsets VGT (Variable Geometry Turbocharger),

Garrett VNT (Variable Nozzle Turbine),

IHI VG (Variable Geometry)

have highly complex design which make it impossible to remanufacture with any degree of reliability.
Best Turbos™ turbo repair and remanufacture program is dedicated for recovery turbo condition /

full service life due to the same quality, specifications and settings being the same as the original turbocharger.

1.When starting your car from cold, do not rev the engine immediately from idle. Allow between a space of 5-10 seconds for the engine oil to reach the turbocharger.

2. Do not operate the engine under full power until the engine oil has finally warmed up. When the lubricant is cold, it remains thick and gloopy and cannot lubricate the turbocharger effectively, until warmed and thinned.

3. Old oil cannot protect the turbocharger adequately. Therefore, do not extend the oil change interval beyond what the vehicle manufacturer has recommended.

4. Low-grade oil cannot protect the turbocharger adequately. Therefore, always use oil that is only not the correct viscosity, but also to the correct quality API specification (the details are noted within the vehicle handbook and also on the sides of canisters).

Need to rebuild your turbocharger? Best Turbos™ uses the highest quality parts in rebuilding turbochargers. We have highly trained and experienced technicians who rebuild all turbos to OEM specifications
