Build the New Car: Monster

After completing the quest "T-Bone" Junction, you will get this quest from Scooter after you complete the quest "Boost the Monster", you will have to find the 3 parts for the machine.

The supercharger can be found in the lowest portion of the level closest to the far right semicircle as seen on the map. It's almost dead center of the map and behind a small shack.

The nitrous oxide tank can be found in the middle of the right semicircle of the map in a trash pile Near Marcus' place.

The exhaust pipe can be found at the bottom of top left semicircle attached to a car that's crashed into a pole. It's right next to Zed's place
