How Do You Know if Your Turbo Is a Garrett on a Mercedes
Tuning the one.nine TDI PD engines
Regarded past many equally the all-time Diesel engine from the VAG group the ane.ix offers plenty of tuning potential.
It had a long production run and is still regarded by many enthusiasts every bit a more than reliable engine than the later 2.0 that replaced it.
The ane.nine TDi was used in a wide variety of cars from the VAG group and came in dissimilar power levels.
All had BOSCH injectors, and Bosch ECU's which are really sturdy and very protective of the engine.
If you desire a quick beginner's guide to tuning diesels please see our new video tutorial.
1.9 TDi Mutual faults & Problems:
There are some reports of the BLE or BXE engines breaking con rods.
The second generation PD engines were bullet proof every bit most of the kinks had been worked out which is more than nosotros can say for the later two.0 TDI engines.
The 1.9 TDi is regarded by many every bit the best VAG grouping diesel engine.
Early on engines suffered from cracked injector looms.

Remaps offer good power gains for very fiddling outlay. Pre 2000 cars volition require a demote flash in most cases simply post 2000 cars will by and large be remappable via the OBD port.
Approximate power figures subsequently a remap with no other mods.
(Carry in heed that peak power figures are only a small part of the equation, the whole torque band is improved).
- TDi90 = 116ps
- PD90 = 120ps
- PD100 = 130ps
- PD105 = 135ps
- TDi110 = 143ps
- TDi115 = 124ps
- PD115 = 150ps
- PD130 = 163ps
- PD140 = 175ps
- PD150 = 182ps
PD engines more often than not give a better power gain than the original TDi engines. Farther gains are possible on the standard block past uprating the turbo units.

Best Engine Mods for your ane.9TDi
- Differentials - improving the diff on FWD cars using the 1.9TDi engine really aid you lot go the power down.
- Mapping - remapping provides the most advantage in terms of cost savings, aftermarket ECUs, and piggyback ECUs are all alternatives.
- Intake and Exhaust - Note that on their own these mods will Not ADD POWER in most cases, but they can help enhance power after other mods by removing the restriction.
- Upgrades to turbochargers - forced consecration upgrades and hybrid turbo upgrades, in item, are the near efficient way to increase air supply, allowing you to burn more fuel and make more power. It is one of the most costly upgrades but provides the best gains.
- Fuelling upgrades, the injectors and fuel pump volition demand uprating for larger power gains.
- Intercooler upgrades - the stock intercoolers are restrictive when running maps so swap in an FMIC that flows better and resists heat soak for longer.
Alert: Do Not FIT A Lite Unmarried MASS FLYWHEEL TO THIS ENGINE! The vibrations will drive you crazy and gearbox life volition be reduced.
Typical stage one mods often include:
Remap, Lighter flywheel (stick with dual mass though, SMF's are not great on the one.9), Sports frazzle, Panel air filter.
Typical stage 2 mods oftentimes include:Ported and polished caput, Ability/Sport clutch, Fast road cam, fuel pump upgrades, high flow fuel injector.
Typical stage 3 mods often include:
Engine balancing, Internal engine upgrades (pistons/head/valves), Contest cam, Calculation or upgrading forced induction (turbo/supercharger).
Differential upgrades to maintain traction on the ane.9TDi
You volition get lots of traction issues around 250bhp, and so bear this in mind, while your wheels spin you won't exist moving!
For a machine that is used on the route in unlike weather weather, I call back the Torsen diff is the best pick.
Torsen ways "Torque Sensing," and it is very subtle in how it works. It comes on very slowly and gradually.
There are some LSDs that aren't very noticeable, and in that location are Torsen diffs that are a little more quick. This all depends on the diff maker and how the car is ready.
Torsen diffs can exist found in a lot of production cars. LSD diffs are ordinarily found in cars with a lot of power or a high price. A, B, and C are the three main types of Torsen diffs. Each ane has different applications and characteristics, and some aren't adept for everyday utilise.
I of the diffs our members recommended was a Quaife LSD. Quaife as well makes ATB diffs.
Remapping the ane.9TDi
How does VW set the factory maps? It accepts that some countries' CO2, HC, and NOx emission targets differ, necessitating a fudged approach - the lowest common denominator if y'all volition.
Manufacturers practise not desire customers to be inconvenienced by mechanical failures or poor fuel economy, therefore they build in a big tolerance.
Depending on how finer the components are machined and assembled, the ability output of each engine tin vary past as much equally 20bhp. Rather than examine each automobile individually and create a custom timing map, they utilise a one-size-fits-all approach.
Manufacturers also employ remaps to create multiple power versions of the same ane.ix TDi engine, lowering insurance rates and improving fuel economy.
So there is plenty of scope to excerpt more ability from your 1.9Tdi with a remap.
Downsides of remaps.
Service your automobile more regularly, peradventure decreasing the interval.
A map optimised for high octane gasoline volition demand you to repair components that neglect due
Additional power puts more pressure on components similar turbos, hoses & pipes, and injectors.
Months afterwards a remap, an engine's weak areas resurface. remap problems, encounter our instructions.
A remap will usually reveal turbocharger and clutch bug.
Also, ane.ix TDi turbos may fail, and critical components like pistons and bearings must be maintained. NASP remaps? A remap volition only add a few BHP without a turbo (10 percent is typical).
TorqueCars encourages non-turbo cars to change starting time (cams, pistons, increase compression, engine balance, air intake, frazzle, head piece of work, bigger valves etc...)
Afterwards that, a remap may assist you become the most out of them.
A remap frequently adds boost from lower rpm, making the turbo operate quicker and hotter.
If you don't let the turbo cool, the oil may deteriorate, necessitating a costly turbo repair. Installing a turbo timer will also help cool the engine.
Non all maps are equal then don't compare peak ability claims
Be wary of peak power claims. Annotation: Some tuners are known to create a ability blip or surge to draw attending and capture headline ability statistics.
See the graph below for an example.
The red trace, at 200bhp, is not that impressive, the acme ability happens quite high up and is only a bleep, whereas ability for the rest of the RPM range is substantially down.
However, the greenish trace indicates a consequent growth in power beyond the RPM range and although just 175bhp it will requite meliorate power than the 200bhp map.
On the 1.9Tdi you would want peak power early on at 2500rpm, which is groovy for an engine that redlines at 5000rpm.
On a map, we want to see a nice smooth torque climb with no dips or troughs.
Injector upgrades on the 1.9TDi
The 1.nine TDi injectors on the PD130, PD150 will be good for 240bhp, injectors on the lower powered engines including the popular PD100 PD105 and PD115 units volition need uprating at 170bhp.
The PD150 injectors are a practiced option to upgrade with, or yous could source some high operation ones.
1.ix TDi turbo upgrade options
Is There a Reason to Upgrade Your Turbo?
Many motorists cull to replace or heighten their cars' turbochargers for the following reasons: Turbocharger upgrades are an excellent way to boost a vehicle'south operation and one of the virtually impactful.
Turbos wear out with fourth dimension, needing periodic replacement. Boosted recent turbos have use of newer technological breakthroughs and provide vehicle owners with more add-on possibilities.
The factory one.9Tdi turbos are supplied for cheapness and reliability non operation so thankfully there are many upgrade options around for these. Here are some that TorqueCars have found to be especially effective based on feedback from our members and my own experiences.
On these engines you can choose from the GTB2566VK good for upward to 245bhp maxing at 3300rpm. GTB2260VK skilful for up to 315 bhp maxing at 2800rpm, GTB2056VK good for upwards to 255 bhp maxing at 2700rpm and the GTB1756VK expert for up to 235bhp maxing at 2600rpm.
- GTD2872VRK 375-400hp @3350rpm 40psi
- GTB2260VK 350hp @2850rpm 35psi
- GTB2056VK 300hp @ 2750rpm 34psi
- GTB1756VK 250hp @ 2650rpm 34psi
There is also the GT2052V good for 225bhp at 2200rpm which would be our choice on a road car at is spools up quite rapidly but notwithstanding provides decent boost levels.
Other Turbo upgrade options on these engines exist if you lot are prepared to change the pipework and manifolds. These include the GTB1749V producing up to 205bhp from just 1900rpm, and GTB1756V which is good for effectually 225 bhp. Some companies offer hybrid turbos which can push button power levels to 240bhp or more with the right additional mods.
NB: Turbos will require conversion to Vacuum actuators and have the VNT organization set upwards.
Choose the turbo where the power band sits in your virtually-used rpm range, the larger power turbos tend to come on boost afterwards.
Guide to Hybrid turbo upgrades for the one.9TDi
A hybrid turbo is a direct replacement for the OEM turbo, simply with modified internals to meet your power needs they are generally bolt on upgrades equally they typically retain the OEM housing and manifold design from your 1.9TDi.
Past modifying the contour of the exhaust side impeller, you may increase the turbo's spool time, extend the power range, or increase elevation end power.
Information technology is often a tradeoff, since you cannot take all of these advantages and must select the best solution for your circumstances. Additionally, modifying the intake compressor's profile may take a pregnant influence on the amount of air that can be drawn into the engine.
Turbochargers use two distinct kinds of bearings.
Bearing options include thrust and ball types. Most OEM turbos utilize thrust bearings considering they are less expensive to manufacture, simply when excessive power is applied to them, they might fail, resulting in oil leaks and premature turbo wear.
A ball bearing turbo will often spool up faster than a thrust begetting turbo and can handle far more power and then is the preferable pick. But nosotros are at present seeing ceramic and cryo treated bearings which further improve reliability.
Not all OEM turbo housings can be changed to convert to ball bearings; instead, an OEM-shaped turbo unit is created to accommodate the upgraded internals.
Additionally, the design of the air intake pigsty has an issue on the turbo'south flow characteristics.
Any ridges, pits, or seams in the metal surface might generate turbulence, impairing the airflow properties. Consider the following advantages and disadvantages when determining the parameters of your hybrid turbo.
On a track where y'all spend nearly of your time at high rpm this is fine only in twenty-four hour period to day driving lots of lag can be frustrating to drive.
ane.ix TDi tuning essentials
110 and 90 VE i.9 TDi Engines will demand uprated fuel injectors as well, the standard injectors on these engines are not skilful at higher power figures. The 150 head bolts are strong, in all other engines you may experience head elevator on stock bolts at large ability gains.
Fit uprated caput bolts or get some bolts for the 150 and fit these instead.
When pushing another fifty bhp through these 1.ix TDi engines information technology is recommended to get a difficult pipe kit, joints and pipes that are onetime are more than probable to divide apart when yous run higher air pressures through them.
New clutches are ordinarily ok with ability gains to the 220bhp. Worn clutches will oft exist ok simply it depends on the treatment and condition of the clutch. Worn clutches seem to skid in most half of the cases where large power gains accept been fitted.
Most one.9TDi OEM turbos are the aforementioned merely the downpipe design and manifolds varied according to the type of vehicle they were mounted in.
Newer 1.nine TDi CR diesel engines are much much cleaner, and they take better fuel direction, and pollution reduction measures but lots of curt journeys can pb to clogging up of the DPF (Diesel particulate filter). Meet our guide on how to clean a DPF for more info.
ane.9 TDi Intercooler upgrades
A larger intercooler will likewise better resist heat soak and would be a adept upgrade on these engines.
In a 1.nine TDi turbo, the cold intake accuse and hot exhaust temperatures are near each other inside the turbo. This tin can be a problem. The large rising in air intake oestrus is caused past the air itself being compressed, so fifty-fifty a supercharged engine volition benefit from having an intercooler to assist it cool down.
Air gets hot when it is compressed. If you have ever felt the nozzle on a tyre pump you volition know that when air is compressed it gets hot. There is more than oxygen in the colder the air is, because we learned about this in our chemistry and physics class.
Why is this important?
A i.9 TDi that has more oxygen has more power considering information technology can burn a lot of gas. You can read more about air intakes in the article.
In a car, what is an intercooler and what does information technology do?
An intercooler is a radiator that cools the air accuse earlier it goes into the 1.9TDi engine.
You should put an intercooler in forepart of the radiator and then that it gets a lot of nice, cold air. Later on, the air intake filter and the turbo or supercharger, where most of the rut is added, it would exist piped into the automobile.
An intercooler that is well-designed can give you five% to 10% more ability from your mods, and resist heat soak for a longer time.
Keep in mind that you want to get as much air into the engine every bit possible, so if the internal core of the intercooler is in the way, you will lose power.
Bigger isn't e'er meliorate, though!
TorqueCars would look a force per unit area drop of between.v and.9 psi for a boost level of 15PSi. In the worst case, some applications could lose ane.3 psi. Information technology's not the intercooler'due south design that caused the whole loss of pressure, it's partly down to the reduction in temperature, and so don't blame information technology for the whole drop in pressure.
In functioning cars, weight is ever a business organisation. Many aftermarket intercoolers are both lighter and more powerful than factory intercoolers, which makes them a good choice for these cars.
As a full general rule, if the intercooler is a petty bigger, it will exist better at cooling, just it will also make the car move slower.
At that place should be a lot of idea put into how much extra drag this will add to the cooling. More air stays in the intercooler, the ameliorate it will cool you down.
Some cars have a spray nozzle that can exist used to spray the intercooler with water or nitrous, which lowers the intake temperature even more as the liquid evaporates using the estrus from the air that passes through the intercooler. This helps the automobile run more than smoothly.
Between 5% and 10% of power is gained from a more efficient 1.ix TDi intercooler design over the manufactory ane (assuming there was a restriction which depends on the fashion the engine has been tuned and setup). This is based on a temperature drop of 35C-40C. The bigger the difference between intake temperature and ambient temperature, the more than cooling effect there volition be.
Every bit fourth dimension goes on, even the near efficient intercoolers will get hot. When y'all drive for a long fourth dimension with a lot of high-heave, the intercooler starts to become hot.
In general, the bigger the intercooler, the longer information technology tin withstand heat soak.
Please aid us consummate this article, if you are aware of any 1.9 TDi engine codes we accept missed, common issues or upgrade options including turbos please let us know, we want to brand this as comprehensive as possible.
Tuning the intake and exhaust on your 1.9TDi
Adjacent, we'll examine the all-time options to improve the 1.9 TDi intake and exhaust to verify adequate engine air and exhaust flow. Please note that on this engine you should be fine on the stock setup to around 220hp.
A comprehensive consecration setup maximizes power improvements if you hit a restriction. We recommend a loftier menstruation console air filter on all 1.9Tdi, they will improve the "off throttle" engine running and give me a niggling more fuel economy on mine without impacting on performance.
Opening the air intake port to friction match the intake manifold would non assist much unless a step obstructs airflow into the 1.9 TDi engine. And then most DIY port matching is done on exhaust ports but we don't really encounter a need on the 1.9 TDi engine.
Extending the port size is only necessary for highly tuned engines when the port size has become a clogging and VW did a great job on the design on the ane.9Tdi.
The greatest ability improvements are generally betwixt ane.5 and 2.5 inches.
