How much will it cost to turbo a celica?
Your 2001 Toyota Celica engine is not set up for the turbo because the engine for the turbo has to be a low compression engine, your 2001 Celica’s engine is a regular compression engine. So to install a turbo on your Celica is not a good idea because you would not be able to gain any more horse power. Furthermore, emission equipments need to be converted to meet the turbo engine family. My recommendation for you is to buy a used Toyota Celica equipped with turbo. The above answer is a short version of the entire idea to convert none turbo engine to a turbo engine.
