Always wanting to find the best alternative, pending whats being done.
have found turbo cartridge replacement £169 UK made with long guarantee
see what sort of job it is to split the turbo then make a decision

Plan A
buy another car, luckily got a Paul Smith classic mini for a very lowly sum, and the guy would most probably like to buy it back when i'm finished, now can start dismantling.
Plan B
If it all goes Pete Tong and I can't manage on my back in the driveway, Paul Smith pays for the work, for a small amount of work which I do love doing
Paul goes back to his or any other owner for a 4k profit
