Description

Direct Replacement Variable Vane or VGT Turbo for Defender, Range Rover & Discovery 300 Tdi.

Direct replacement for original Garrett requiring no modifications.

Kit includes new oil feed pipe, oil filter and gaskets. You will need to supply good quality oil of the correct grade and inlet / exhaust gasket (also available on request)

Designed to use original manifold outer sections (bull horns) but we also offer new items to make installation even easier.

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.

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.

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.

    Turbina stupenda, ottimo pezzo e si monta senza fare altre modifiche.
    Un po’ più complicata è la regolazione, ma va fatta da un meccanico o da un pompista.
    (Gorgeous Turbo, great part and mounts without making any other changes. A little more complicated is the adjustment, but it is done by a mechanic or pump.)

    Hi Andrew!
    Just a update: I finally have installed the turbocharger this week, it’s amazing! There is no turbo lag anymore, very cool. I had to make some minor adjustments to fit it on Brazilian 300tdi, and I would like to share with you what I learned, in order you can advise further buyers from Brazil:

    – We have a different oil feed pipe that uses a banjo bolt on both sides
    – The exhaust connection is the same, but about to 10cm shorter; It was easy to solve welding a pipe to make it longer.
    – Our 300tdi is not fitted with EGT, so the blanking plate ERR4698 is required
    – Finally, as we already knew, the exhaust manifold is very different, and the “bull horns” are required to be purchased together.

    I’m very satisfied, and I hope you could sell many others to Brazil, I will certainly recommend your products. Thank you.

    Vehicle: Defender 300 Tdi / International Maxion HSD 2.5

    Easy to install (even for an amateur like me).
    I only had one problem. I had to place the steering shaft upside down, because the joint was rubbing against the silicone hose between the intercooler and the turbocharger.
    Makes (in combination with my larger Allisport Intercooler and silicone hoses) a very big difference.
    Feels like driving an entire different car. Going up a steep hill is not a problem anymore. I don’t have to gear down…plenty of power.

      Thank you for your review, we are glad to hear you are pleased with the products. We are not aware of the problem with the steering, it could be a nonstandard steering joint perhaps. We would be happy to look at a picture of the problem and advise.

    Hi to Andrew, danke für die großartigen Produkte. Ich fahre einen 300 TDI in der Dominikanischen Republik, das Fahrzeug ist in ursprünglich deutsche Ausführung.
    Wir haben XXL Front mount Ladeluftkühler sowie den VGT Turbo verbaut, sowie den Luftfiltereinsatz und die Silicon. Schläuche von Allisport verwendet. alles hat super und perfekt gepasst.
    Die Leistung ist überraschend gut! Der Drehmoment Zuwachs in den unteren Drehzahlen sehr groß, was natürlich ein unglaublicher Fahrspass nicht nur im Gelände bringt. Es ist nahezu kein Turboloch zu spüren.
    Preis zu Leistung sehr gut. Ich kann jedem der einen 300 TDI fährt dieses Upgrade empfehlen.
    Die technische Unterstützung auf die Entfernung, als wir Rückfragen zur Dieselpumpe hatten war ebenfalls sehr gut. Hier nochmals danke an Andrew und sein Team. Einfach Professionell!
    Später habe ich noch den Hauptkühler der aus Altersgründen defekt war gegen einen von Allisport getauscht, auch dieser ist in einer Topqualität.
    Danke und Grüße aus der Dominican Republic
