Cameron02 Member 164 Member For: 11y 4m 15d Posted 28/12/12 02:13 PM Share Posted 28/12/12 02:13 PM Down the track I would like to ceramic coat my headers, turbo and dump pipe to reduce engine bay heat and increase the life of engine bay components. I would need to pull the turbo apart so that I could send the exhaust side in for coating. Is there anything special I have to do when dismanting the turbo (only enough to get the exhaust side seperated)? For example do I have to mark fan/rod positions etc. Or is it pretty much pull it apart and clamp it back together again. Link to comment Share on other sites More sharing options...

Easiest way (IMHO) to do this is to use either some spacer sockets are suitable spacers between the head of the exhaust housing bolts and the CHRA, place them between the two and as you remove the bolts they will jack the front housing off the rear.

If I dont put the exhaust housing back in the same position then the actuator attachment will not line up and neither will the dump pipe?Trying to understand what you mean about the spacers. What is the CHRA? Link to comment Share on other sites More sharing options...

Red R6 Donating Members 41 Member For: 11y 4m 18d Posted 29/12/12 02:38 AM Share Posted 29/12/12 02:38 AM (edited) Be very sure you will always have time to let your turbo cool down before you turn your car off as keeping the heat in the turbo can cause bearing failure when its off as the coolant and oil stop flowing.

Cameron02 Member 164 Member For: 11y 4m 15d Posted 29/12/12 03:26 AM Author Share Posted 29/12/12 03:26 AM Thanks Red,I did not think of that. I guess that would be good advice for any turbo, not just a coated one?Do you know if they are able to coat the inside of the turbo or just the outside. Will coating the inside mess with tolerences? If they do coat the inside then the inside should cool down more quickly than standard. If they can only coat the outside then yes, the inside of the turbo would take longer to cool down.

Remember when a turbo fails it can result in fine metal particals going into the intake system and destroy your bores and rings (it happens all the time on R32 GTR's) Link to comment Share on other sites More sharing options...

People who block their intake to make the fluttering are another culprit for damaging turbos Link to comment Share on other sites More sharing options...
