Simple Air Engine (No Hardware)

On my profile there is a mini turbo that fits this engine! more parts are soon to come like the exhaust pipes that connect to the air engine intake to the exhaust of the turbo! there are 2 intakes and 2 exhauston the engine. The two exhaust dont have a slit, and the tubes for the intake of the turbo fit on those exhaust holes. One of the intake holes is for the air pressure the other intake hole will be fed by the exhaust of the turbo!
