JTD-Performance

After having worked at many Alfa's with JTD engine, we were asked to do a power transformation for a Giulietta QV. The idea was to keep the stock turbocharger (for now anyway 😉 ) and to optimize all the relevant parts to get the best possible performance with this setup, but with a stealth look and sound. So we mounted our intercoolerkit, replaced the stock airbox with a performance airbox with cool air infeed, mounted a full stainless exhaust line with 3" front section, sports cat, and 2.5" centre section with Ragazzon rear silencer. And last but not least, to keep the intake valves clean (disadvantage at direct injection engines) and increase power even more, we fitted a SnowPerformance Stage 1 water/methanol injection system, with the WMI tank placed in the engine bay.
Let's call it a Giulietta QV, the "JTD-Performance way".
The first results at the road are very promising, but to see the real potential, this car will be mapped and tested at the dyno very soon, so stay tuned for more updates!

JTD-Performance

Newly available for the 166 2.4 JTD 20v, the JTD-Performance intercoolerkit. In general, the need for performance parts for the 166 is less compared to the more popular 147,156 and GT JTD, but fact is, that the Alfa Romeo 166 coupled to this 2.4 20v euro 4 (version without DPF) engine is one of the "tastiest" JTD's available. This engine, which is basically the same to the ones found in 159's is very tuneable, and the total weight is approx 100 kg less for the 166. However the weak point for the 166 is the stock intercooler, and that's where this upgrade comes in. On this car we were able to drop the intake temperature with 25 degrees during a 4th gear log. Looking at the temp curves, it is obvious that the difference is only getting bigger at longer durations of full throttle. After a remapping session, the torque curve shows a broad band close to 500 Nm without any visible smoke output. It makes this 166 an elegant powerhouse! ... See MoreSee Less
