Hi all, a little while ago I seem to remember reading that it is possible to fit a variable turbo to a tdi. It was suggested that a turbo from a merc sprinter or vito van was used but I can't remember which one specifically. Is this something that anyone here has attempted and if so what were the pros and cons of the conversion?
Cheers in advance. Rhubarb and custard let fly with their secret weapon. |

We do a bolt on VNT conversion for the 300tdi here http://bellautoservices.co.uk/products/vnt...vgt-turbo/ Our 200TDI conversion will be available very soon.
The VNT we sell is made especially for the 300TDI and is cast specifically to fit directly as a replacement unit which gives masses of power more over the standard turbo. The turbo is nearly double the size of the factory unit. Here are a couple of pictures below showing the standard turbo and our VNT hybrid, you can clearly see the size difference in the two units. It also shows that the fitment is as factory standard of which can be done by any novice mechanic with no extra components needed like special manifolds or expencive pipe work needed.

Pete, that looks very interesting
. Do you do a fitting service and if so are the 300tdi prices on your website? I havent got time to check right now as im at work. Do you recommend replacing any other components whilst im at it? |

Hi
Yes we can offer a fitting service for the turbo, it will need at the same time new oil and filter as part of the install. Fitting will be around 100+parts+vat and we will need the car for day to do the work. Even more power can be gained from the engine/turbo when fitted allong with a performance intercooler. Allisport offer a double core 300TDI drop in cooler which greatly increases air flow and cooling for the ultimate performance package. Below i have copy and paste the text about the turbo from my web site for ease of reading for all. So what’s special about our 300TDI Defender, Discovery and RangeRover Variable Geometry Turbo? All turbo’s are a method of forced induction – i.e. forcing a greater mass of air into an engine. A conventional turbo consists of two main parts, a turbine (driven by the exhaust gas from the engine) and a compressor wheel (driven from the turbine wheel via shaft). A turbo charger needs to be exactly matched to an engine to ensure it works correctly. In simple terms, if the turbo is too big, you will get turbo lag due to the time taken for the exhaust gas to spin the turbine wheel fast enough to produce useable ‘boosted’ pressure. If the turbo charger used is too small, then it will spin to fast (thus damaging the turbo due to over speeding) and it will also ‘throttle’ the engine as it will not be able to supply the volume of air required. However at low speeds you will have next to no turbo lag. As is often the case, turbo selection is always a compromise – you want a big turbo so you will be able to compress more air – thus get more power, but at the same time, if you go too big, you will induce turbo lag. But then if you go too small, you will restrict engine performance. A Variable Geometry Turbo is basically a turbo that can adjust itself internally. So now you have the turbine wheel, the compressor wheel, and a set of veins that direct gas flow around the turbine wheel. At low engine speeds (when the engine will be exhausting less gas) a Variable Geometry Turbo acts like a small turbo, so makes full use of the lower volume and lower speed of the gas being ‘exhausted’ by the engine. This means you make full turbo boost pressure at a much lower engine RPM – which, when matched with correct fuelling – dramatically changes your/the low speed torque, and ultimately how your Land Rover drives at low speeds. As engine speed (and load) increases, the turbo adjusts its internal veins to slow the speed of the turbine wheel down, and ensuring that it spins fast enough to ensure the compressor does its job (i.e. making the required boost pressure) meaning that the turbine doesn’t over speed. Our Variable Geometry Turbo conversion doesn’t just make a difference at low speed it also ensures that the turbo is always working at its optimum setting regardless of load/engine speed (RPM) – this means that turbo lag becomes none existent. When you put your foot down you will instantly you will feel the effects!! This can never be obtained with a standard Fixed Geometry Turbo. All our turbo chargers are designed and made by Turbo Technics, who specialise in automotive turbochargers and associated turbo equipment. Turbo Technics are a world-class company acting as consultants to many car manufactures who use their turbo remanufacturing facility for many car brands including JLR, which gives us the edge with our specially made Hybrid turbos as we know that they are built correctly and come from the same factory which Land Rover use for their own remanufactured turbos! Priced at only £895 + shipping + VAT where applicable. This price is based on you using your own manifold ends “bull horns” from your existing turbo manifold. |

What's the fitting like on these? On one hand it says you need the ends off the old manifold and on the other it says its a straightforward fit - so wondering what you have to do with the old manifold - cut it up?
How much extra for an export order without returning the old turbo? |

Hi
The turbo is a direct replacement so fitting is easy, the old manifold "bull horns" slide out of your old turbo manifold. for non UK orders and forum orders exchange is not needed you can keep your old turbo. Pete |

I think it was working,just bought the motor, and though best to update the engine was manufactured in the late eighties and been standing in a field for nine years, on the isuzu forum some one said best to update, it is in a Land Rover 127/130 made in 1986 still trying to find out when the isuzu engine was put in, Found this The 4BD1T is a turbocharged version of the 3.9 L 4BD1, it was produced from 1980 and was fitted to Isuzu NPR trucks from 1986 and sold in the US. Approx 135PS peak torque is 330Nm at 1800rpm, also use in jeepneys in Batangas, approx 180kph on its high and low transmission they use. The engine was also used in the Australian Penrite. Will get a beter picture tomorrow, one of each side.  Live Life Ti'l You Die
