Right!! Turbo is off, and I have these cracks around the waste gate, I know they do crack around there, should I weld these up? Do they look bad to you guys? The hot side won't come off so going to get some heat on it tomorrow and hopefully that will persuade it off.

Thinking of having a go at rebuilding it myself and then having it balanced! I've got to try and save money where I can, and will be good to learn!
Any body able to link me to rebuild kits for the gt3071s? Only ones I've found so far are from America. anyone?

Well the turbo has been rebuilt by midlands turbo with an uprated brass cage, they have done a what looks like a great job, even repainted the whole lot, looks brand new! And I've finally managed to find a housing from a company in Germany brand new, all together it's cost me £550.....gulp Sad

turbo work rarely cheap, good to get rid of the plastic caged bearing, Garrett are shoddy fookers ...

I never understand why they still continue to supply them like it when they are common to failure you would think they would just use the metal cage to begin with scratch

Other companies make to much money selling and doing upgrades bits and builds. garret claim it's because you push the turbo to hard and heat melts them

Not sure mate thought it was a blade design and material change. Not sure on the bearings

"Upgrading it to a Garrett GTX CHRA would be perfect as that comes with a billet wheel and bronze ball bearing carriers"

I was asking midlands turbos about upgrading to brass bearings and billet compressor got this answer ...
