I want to build my maxima to get down and dirty on a dirt track. I would rather have low-end torque for this and want a responsive turbo so will likely opt for a smaller one. my question is will my car gain hp at all rpms with a turbo compared to naturally aspirated? At a certain rpm, the turbo does not give much gains and chokes the engine but is it to the point where it is weaker than the same rpm naturally aspirated?
