12 months warranty on all units
The K16 turbocharger is the large turbocharger and is mainly responsible for the power output in the higher engine speed range.
The KP35 turbocharger (123d & xDrive23d) and BV35 turbocharger (125d, xDrive25d, 335d etc) is the small turbocharger, and is mainly responsible for the torque output in the lower engine speed range.
Where only 1 turbocharger is selected for modification, that particular turbocharger will be modified to have characteristics which compliment the other turbocharger still being original.
Maximum safe possible power for each variation of the K16 turbocharger is as follows:-
71mm 485ps (535ps with the XL compressor wheel)
Price is for an exchange turbocharger, if you wish to send us your turbocharger for modification, then please use the address provided in the email you receive after purchase. If you wish for us to send you a turbocharger first, please add THIS surcharge to your basket, this deposit will be refunded once we receive back your original unit.
Total peak power as a guide only, this is based upon the flow data of both the compressor wheel and turbine side as a whole, every engine build is different and thus will yield different results. ‘safe’ limitation is based upon the compressor map characteristics, considering all possible engine modifications and improvements in volumetric efficiency, and staying within the surge and choke limits of the compressor map.
Turbochargers suitable for all 2.0 N47 twin turbo diesel engines fitted to 123d, 125d, 325d etc

³All journal bearing turbochargers are fitted with an upgrade thrust bearing and assembly to allow higher boost pressures and still provide reliable thrust load support
If you are modifying your diesel engine, your standard turbocharger will need upgrading. Some manufacturers fit turbochargers so small, its a wonder they even bothered fitting them at all. This is where we come in to help.
These hybrid turbos, will happily see you towards your goal of achieving more power, in a safe and reliable way. They have very good flow characteristics, can run at much higher boost pressures than standard, and are guaranteed to last a minimum of 12 months. They are available in different sizes, so its possible to choose the perfect hybrid for your application.
A brief overview of turbocharger compressor wheels:
Cast – made by pouring molten metal into a mold
Billet – made by cutting a solid block of metal to the correct dimensions
5+5 – 5 major compressor blades & 5 minor compressor blades
6+6 – 6 major compressor blades & 6 minor compressor blades
7+7 – 7 major compressor blades & 7 minor compressor blades
8+0 – 8 major compressor blades & no minor compressor blades
9+0 – 9 major compressor blades & no minor compressor blades
10+0 – 10 major compressor blades & no minor compressor blades
11+0 – 11 major compressor blades & no minor compressor blades
STD – standard size compressor wheel
Extended tip – the exducer blades (large diameter) have been extended
Extended tip & nose – as above + the inducer (small diameter) has been raised
Super Titanium billet XLT® – a billet compressor wheel milled from a solid piece of titanium alloy
5+5 is best for applications that require a very high boost to flow ratio, for example where stock camshafts and only minor intake modifications have taken place, on small displacement engines.
6+6 is best for applications that require a high boost to flow ratio, for example where stock camshafts and only minor intake modifications have taken place
7+7 is best for applications where a little more flow is available, through larger intercooler systems or more freely flowing intake manifolds
11+0 is for the pinnacle of performance. They have the highest flow to boost ratio, which with the larger compressor wheels, can make them susceptible to surge on engines which haven’t made improvements in the valvetrain area, and have high intercooler pressure drop for example.
8+0 / 9+0 / 10+0 are similar in performance to 11+0 compressor wheels, however with smaller wheel sizes 11+0 would add extra weight with no benefit in flow ability. The spacing between the blades, vs the overall length of the blades from the centre of the wheel axis, changes with wheel diameter, so smaller wheels use less blades to keep the blade tip spacing in the range best suited for high air flow performance. With same wheel sizes, 8+0 will flow less air overall at the same boost pressure as a 9+0, so has a higher boost to flow ratio in comparison. The same is to be said for a 9+0 vs a 10+0 and so on.
STD wheels will flow a good amount of air, the volume of air entering the compressor wheel is in a set ratio with the pressure of air leaving the wheel, this is ideal for lightly tuned engines.
Extended tip wheels will add an increase in boost pressure over a STD wheel size, and are ideal for applications where there is enough air flow from a standard sized wheel, but the engine requires more boost pressure in order to make extra power.
Extended tip & nose wheels are ideal for applications that want the absolute amount of air flow and boost pressure possible from a particular wheel size. These are the highest flowing of all wheels in a particular size, and will provide the best performance on a tuned engine.
Super Titanium billet XLT® wheels are the ultimate compressor wheel for the most demanding of situations. Built for ultimate strength, they can support 10-15% more boost pressure and air flow than the equivalent billet aluminium compressor wheel, and thus are able to support 10-15% more power than the equivalent billet aluminium wheel. Higher rotational speeds are possible due to increased strength with less weight, and less load on the turbine shaft and bearing assembly due to lower centrifugal forces.
If you are struggling to decide which turbocharger is best for your application, send us a message HERE and we will get back to you with a recommendation as soon as possible.
Price is based on exchange for fully working original turbocharger, which you send to us and we carry out the refurbishment and modifications required. If you wish for us to send you out a turbocharger first, and you return yours later, there is a surcharge (deposit) to pay, which is refunded upon us receiving back your fully working original unit. Please add THIS surcharge to your basket if you wish to purchase the turbocharger outright, or want us to send the turbocharger to you first and you return yours later. If you don’t add this surcharge to your basket, you will not be sent a turbocharger until we either receive your original or the surcharge.
12 months warranty with all units.
