Direct Replacement VGT Turbo for the TD5 powered Land Rovers.
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. TD5 VGT units use a special actuator operated by boost pressure to control the vane angle.
Our VGT 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 often reduced and compliments any other tuning such as an uprated intercooler.
The kit is supplied complete with all gaskets and new oil feed pipe required to complete the installation.
Also supplied is a turbo boost control unit to correct ECU overboost faults.
To get the best from the turbo it is beneficial to use a specific map but improvements in driveability will be seen with any map or even 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.
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 exhaust manifolds and exhaust components.
Note that the turbo is likely to sound different to standard units
As this is a non-standard turbo, Turbo Technics offer a limited warranty of 3 months. Full terms available on request.
