    TBI will look like a normal carbureted car. The air filter housing is round and will be in the middle of the motor on the top.

    TPI will have the intake connected to the front of the motor on the top. The air filter housing is separate.

    TPI looks like this:

    tbi has injectors that look like a carburetor and the most of the time the tpi motor says tpi on top of the engine
