| Since turbochargers are a universal fit, meaning you can adapt them to everything/anything that is an internal combustion engine there is infinite ways to mount them. In order to make turbochargers work within a given space often times the compressor and turbine housing must be rotated in order to allow for fitment. The rotation of the housing in relation to one another is called "clocking". Here is a step by step, picturial guide on how to "clock" a turbo: 1. Grab your turbocharger. The one pictured is the ultra exotic GT28RS. 
2. Now take the turbocharger and place it on the compressor inlet. You should see a total of 6 bolts, and three backing plates. Pictured is two of the bolts holding the backing plate. 
3. The 6 bolts that are holding the compressor housing on are a 1/2, so grab your 1/2 box wrench. 
4. Using the 1/2 wrench, loosen the 6 bolts. 
Here is another shot of the backing plates, bolts and me loosening them. 
5. You want to loosen the bolts just so they are not "biting" into the backing plate. Their purpose is to hold the backing plate against the compressor housing, and not allow it to rotate. Here is about how far you should back them out: 
6. Now that you have all 6 bolts loosened as pictured above, flip the turbo so that the compressor housing inlet is facing up: 
7. The compressor will rotate freely, just move the housing to the desired position. 
8. The turbine housing will need to be rotated, there is 6 bolts holding the backing plate on. Using a 1/2 box wrench, loosen all six bolts in the same manner as the compressor housing and rotate the housing to the desired position. 
Its as simple as that. |
