Disassembly of Engine Components
Before the engine conversion can take place, several of engine components must be removed to allow unobstructed working access to the turbo compressor shell.A good practice is to "bag and tag" all removed components along with plugging all apertures to aid a quicker and easier reassembly process.The photographs below show the components that are to be removed in the preferred order.Note: The new coated turbochargers will have been supplied with a 5 ° downward rotation to align with the new charge air pipes.The photos below illustrate the various stages of removal of the old cross over pipes.
