Reasonable tuning closes with a power of approx 200 HP and a torque approaching 400 Nm. There is no need to interfere with any mechanical components. After modifying the boost, intake and exhaust, you can target over 200hp and over 400Nm. The 1.9 TDI engine is very resistant to loads and high mileage. When this engine code pops, 9 times out of 10 it is the intake manifold runner or the flap position sensor that has failed. This code is most common on the earlier 2.0t TSI & 2.0t TDI Volkswagen engines. The majority of the time, this code will be covered under VW extended warranty, so the first thing we advise is to call VW directly or your New-old stock crate engine that never been run or even in a vehicle. Bought as manufacturer spares from VW after the end of the vehicle’s warranty period. The exact variant type is 1.9 R4 8v TDI PD ANU (66 kW (90 PS; 89 bhp) at 4,000 rpm; 240 N⋅m (177 lbf⋅ft) at 1,900 rpm). These can be tuned to 220BHP without too much fuss for a lot of Below are step-by-step VW Jetta timing belt installation instructions and tips developed for the 1.9L BRM engine code TDI. Our hands-on experience has helped us create instructions that are specific to this engine. This how-to guide includes instructions on the removal and installation of all timing belt systems and related timing belt components. ACME makes an adapter/flywheel to go from that bell and input to the 1.9 TDI. The tranny is the Jeep 23 spline input to go to a drivers drop NP231J (or you going put the 23 spline input in the NP231C the s-10's come with). I sold the TDI, too many projects, but I still have the bellhousing, tranny, clutch fork, clutch throw bearing, clutch fork Tested the TDi engine with mechanical injection successful. The little four banger could push the 25foot boat to plane with five people on board. We reached 22mph. Had water meth injected to keep EGTs under control and for about 30hp extra power. The boat planes without water methanol at around 19mph. The VW Transporter 1.9 tdi had relatively few engine problems The engine and gearbox combination in the 1.9 was well tried and tested by the time it arrived in the later T4’s and T5’s. The 2.5L was brought out later and uses a much more complex timing mechanism that make them harder to work on. The only good things about the PD engines were the reliability and fuel economy. The diesel clatter was awful. More modern diesels are generally more refined, but I still don't like the diesel .
