Direct Replacement Variable Vane or VNT Turbo for the Land Rover 300Tdi engined Defender and Discovery supplied with new oil feed pipe and filter.
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 VNT or VVT – Variable Vane 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.
Our VVT units use a special actuator operated by boost pressure to control the vane angle.
Our VNT 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 the uprated intercooler.
