A number of people (including myself) have automatic transmissions on Turbo cars. I know of no one who has had any reliability issues with the Auto trans with the additional power of a Turbo engine. I believe the specifications for HP and Torque for the Houston engine are less than the Turbo, so I don't think you should have any problem with it. A call to DMCH may yield a more accurate answer to your question. As far as opinions on the Houston setup, I do not own one but having seen them demonstrated at past events I think they are WAY too loud.
