Turbocharged engines are slightly different to standard engines. This is because they use excess gas to bring more air into the intake valve while a non-turbo engine, also called a naturally aspirated engine (NASP), uses natural air for this. Fitting a turbo to a non-turbo engine is a difficult job, but it’s not impossible.
What you need:
The turbo needs to be the appropriate size for your engine. TD04 is a popular choice among cars between 1.6 to 2.0 L.
You’ll need to make oil line modifications on any non-turbo engine in order to attach the turbo to the vehicle’s oil system for cooling. This could require sump modifications as well.
Sometimes you will find that there are already pipe kits that can connect the turbo to your vehicle’s intake manifold. If you cannot find a kit for your model of car, you can have them custom made.
You’ll need to invest in either a piggyback or standalone electronic control unit (ECU). This is so that the ratio of air and fuel injected in your engine is maintained. The piggyback ECU intercepts the signals entering and exiting your current ECU. A standalone ECU is pre-programmed and replaces your current ECU. The standalone ECU is the more expensive option.
You should consider having your turbo installed by a professional . They will take all the necessary precautions and change what needs to be changed for the turbo to run perfectly on any engine.
