Generally, you'll need to consider these factors:
* Emissions Regulations: Adding a turbocharger significantly alters the engine's performance and, consequently, its emissions. Most jurisdictions have strict emission standards, and modifying your car to exceed these limits is illegal. You might need to get the modified car re-inspected and certified to meet current emissions standards. Failure to do so could result in fines or even the vehicle being deemed unroadworthy.
* Vehicle Registration and Inspection: Modifications like turbocharger installations often need to be declared to your vehicle registration authority. Failing to do so is illegal in many places. Your vehicle may also fail its annual safety inspection if the modifications are deemed unsafe or improperly installed.
* Insurance: Your insurance company needs to be informed of significant modifications to your vehicle. Failing to do so could invalidate your insurance coverage in the event of an accident. Some insurers may refuse to cover a car with unauthorized modifications.
* Local Laws: Specific regulations vary widely between countries, states, and even municipalities. Some jurisdictions may have stricter rules regarding vehicle modifications than others.
In short, while it *might* be technically possible to fit a turbocharger, it's highly likely to be illegal unless you comply with all relevant emission, registration, inspection, and insurance regulations. You should always check with your local Department of Motor Vehicles (or equivalent authority) and your insurance company *before* undertaking such a significant modification. Improper installation can also lead to serious mechanical problems and safety hazards.
