Hi,
Okay, I still tune Ford TD engines.
So, from the 55kW/75hp-152Nm engine in the Serra, you can easily get around 90hp-175Nm, which makes it a real powerhouse. The engines in the Mondeo and the Escort have 90hp-180Nm, but there are a lot of differences compared to the Serra. For example, the throttle, boost pressure, intercooler, mass airflow sensor, etc. All of this results in around 110hp and about 205Nm.
To get the Sierra up to around 90 hp - 175 Nm, you'll need to install an intercooler, but you'll have a lot of problems. If you want to install the intercooler before, I always do it in the engine bay so that the middle air intake of the intercooler is cooled. The air control system must be redesigned, and the pump must undergo new optimization.
I have a few tuning parts for the Sierra, along with an installation manual, sitting in my storage. If you're interested, you can send me an email.
