Direct Replacement Variable Vane or VGT Turbo for 300 Tdi.
Kit includes new oil feed pipe and filter and gaskets. You will need to supply good quality oil of the correct grade. Inlet / exhaust gasket available on request.
Standard, fixed geometry turbo design is always a compromise. Engines need a small turbo for fast spool-up and improved throttle response (reduced turbo-lag) but the small compressor size does not allow enough flow for anything beyond mid-range revs. So a larger turbo is required for mid-range and higher revs and increased flow, but this leads to increased lag at the low end.
The VGT – Variable Geometry turbocharger acts like a small turbo initially then alters geometry to increase flow in higher revs, giving an improved spread of power across the rev range. Tdi VGT units use a special actuator operated by boost pressure to control the vane angle.
The VGT unit is designed to be a direct replacement for the original requiring no mods to the car.
Power is improved throughout the rev range but particularly in the lower and mid-range revs.
Turbo lag is reduced and compliments any other tuning such as an uprated intercooler.
The kit is supplied complete with all gaskets required to complete the installation.
To get the best from the turbo it is beneficial to adjust the fuel settings however, improvements in driveability will be seen even with standard tuning assuming a healthy engine..
The following must be considered prior to installing an after-market turbo charger –
An uprated intercooler must be used along with – Fresh oil, filter, feed and drain connections. If the engine has been rebuilt or the turbo has previously failed, at least two complete engine flush processes must be undertaken. Oil pressure must be checked and verified as correct and the original cause of failure ascertained and rectified.
The aftermarket turbo charger must be installed by a professional mechanic following the recommended procedures supplied.
Non-restrictive intake system – we advise against the use of a raised or nonstandard air intake. Please note – any restriction to the air intake on performance turbos will invalidate warranty. This can include raised air intakes.
Correctly sized exhaust system – either restrictive or too little back pressure can cause problems with uprated turbos and can invalidate warranty.
Please also see our listing for improved flow intake hoses and exhaust components.
Note that the turbo is likely to sound different to standard units
Turbo Technics offer a limited warranty of 3 months. Please be aware that Turbo Technics warranty is based on the unit being returned at your cost for inspection. Full terms available on request.
