Engine performance parts for JTD and TBi engines
Lately a lot of oil pressure related posts here, so let's talk about something that we're really passionate about! Which is increasing the performance of the Giulia-Stelvio 2.2 JTDm engine. ![]()

A new post with the 2025 mods is in preparation, so let's start off with this dyno test we did a couple weeks back.![]()

After the lastest mods we logged 345 hp / 680 Nm with the Performance Logger, so we wanted to check what we'd get on the dyno. (Thanks to Tuning-shop.com) ![]()
During the dyno runs we always have the datalogger connected so we can check if the engine performs the same as in road testing. The short answer is, it doesn't! Lack of airflow had us triggering AFR and EGT limiters during dyno pulls that lowered the output especially above 3500 rpm. See also the comparing graphs of the injection quantity of road vs dyno tests.![]()

The result at the dyno was a (still respectable) 335 hp and almost 700 Nm of torque, and with the reduced IQ on top, we believe that 345 hp is a very realistic number.![]()
As that power may not seem super high for a modern 2.2 diesel engine, it should be noted that this came without smoke, and with a decent powerband. 600+ Nm in 2100-3800 rpm we proudly call "Torque City"! ![]()

More to come, as we're not finished with this engine...![]()
