How to Build a Turbo Car
- 1). Mount the turbo housing close to the throttle body of a fuel injected car. Use a mounting bracket to secure the turbo in a place inside the engine compartment where the hood can be closed and the turbo is as close to the intake manifold as possible. Use a wrench to bolt the mounting bracket to the engine using an existing accessory mount. A forward air conditioning compressor is a good place to put the turbo mount.
- 2). Remove the exhaust manifold closest to the turbo housing with wrenches and dispose of properly. Engines without manifold but with headers can use existing headers for the conversion.
- 3). Install an exhaust header and cut it so that the only piping left is closest to the header flange. Measure the distance from the ends to the turbo housing and draw up a diagram of the new exhaust header with measurements.
- 4). Weld together a header using new exhaust tubes to join all four pipes into one collector tube before entering the turbo at the exhaust inlet. Secure the end of the new turbo header to the turbo inlet using an exhaust flange to secure the two together.
- 5). Drill and tap a hole in the bottom front of the oil pan to collect oil for the oiling system of the turbo. Screw in an oil fitting to accept an oil line and run an oil line up in front of the firewall of the vehicle. Use brackets to hold the line to the firewall and then direct the loose end of the line toward the turbo housing oil fitting. Connect the oil line and oil fitting together.
- 6). Cut a down pipe from new exhaust tubing to exit the turbo housing and run down to the old exhaust system under the vehicle. Create a custom "candy cane" tube that runs over and down the firewall of the car toward the muffle to expel the turbo exhaust gases after being used.
- 7). Connect the turbo housing to the intake manifold using a hose and hose clamps to make a tunnel connecting the throttle body and the turbocharged air supply coming out of the front of the turbo housing.
