More common in petrols due to higher temps. But can happen with any engine.

Just a point of interest. Was reading new thread Help by aulburyscott and some recommendations for tubos came up - so I started looking at the Borg Warner EFR6258.

Came across comments like these (any cause for concern?):

Please be advised that BW has had some casting setbacks, and not ALL EFR units are shipping with the investment casting turbine housing. Furthermore BW has instructed all distributors NOT to open the boxes to verify if they have the investment or sand cast housing. If you recieve a sandcast housing you are still liable for return freight and restocking fees if you want to return the unit.

Oh ye of little faith. Which one did you get and where from?

Same as justins. Fits fine, just need to figure out how to clock the cartridge bit.

Guessing I need to remove the big circlip to clock it. Also guessing I need different springs for the actuator to gain more boost??

Cant help on the clocking, but it would be good to see a photo or two showing how its done once you work it out.
