How long should a TDI turbo last?
In my experience with turbo engines, they have lasted between 150,000 to 200,000 miles. The problem that seems to be the limiting factor of their lives are the oil seals and the bearings that hold the shaft between the impeller and the compressor turbine.
How long do Volkswagen Turbos last?
That said, there are many turbo engines that can last long. Take, for example, the turbodiesel in the Mark IV Volkswagen Golf / Jetta (from early 2000’s). Many of them are going well past 200K miles with good maintenance.
What kind of engine does a VW Jetta have?
A second injector nozzle option, the popular PP764 nozzle, also offers a path to 180whp or more. Found on the 150hp European version of the 1.9L engine, the Garrett VNT-17 has long been a popular turbo upgrade for state-side Jetta TDI’s.
Is the VW Jetta bv39b twice the power?
In conjunction with DLC 1019 nozzles and custom tuning, we’ve seen the BV39B support twice the factory torque rating and a 75-percent increase in horsepower without sacrificing any drivability, fuel economy or engine longevity (the car is still running the exact same, six years after the build).
Are there any modifications to the VW Jetta?
In fact, over the past 15-20 years of playing with these cars, so many parts combinations have been tested that—for all intents and purposes—ALH Jetta performance has been nailed down to a science. From high-flow injector nozzles to drop-in turbo upgrades and performance camshafts to custom tuning, everything is available for them.
How much boost does a VW Jetta get?
When retaining the factory overboost protection functionality, the OEM 2.5-bar MAP sensor will only allow you to make 16-18 psi of boost. With the 3-bar MAP sensor in the mix, roughly 23 psi of boost can be seen. Beyond that, Malone Tuning offers a Bosch 4-bar MAP sensor for even higher boost potential.
