Converting your car from non-turbo performance to a turbo car performance in a proper way would cost thousands of dollars. Why? This is because you would have to replace almost everything when converting your car from a non-turbo to turbo. First, you would have to choose an engine and the possibilities here would be endless. If you choose to stick with what you have and it would most likely be an aspirated one then you would have to adjust the level of compression level to 7.5:1 so that your engine would be able to handle the heat and the pressure that turbo boost would generate. You would have to purchase stainless steel valves for the cylinder head to attain durability and forged pistons and total-seal rings to ensure reliability and performance. Not to mention having the car’s fuel management changed to fuel injection.
After preparing the car for turbo conversion and installing a turbo charger then you would have to purchase a lot more parts. Not only would it be a source of a head ache because there are so many to choose from, but it would also be very expensive. You would have to buy a waste gate, fabricate a turbo exhaust manifest, boost controllers, boost valves, compressor by pass valves and inter cooler plumbing to name a few. Fuel injector parts are also usually upgraded. This is why it is tempting to just partially convert the car; this however may result in you spending even more money than just properly converting the non-turbo car into a high performance turbo car.
