335i new turbos

[Fury RS]

Hi, my 335i has just had brand new turbos, oil feeds pipes, fresh oil and filters, gaskets etc fitted. Is there a recommended run in period for these or is it ok to use as before? Would it be beneficial to fit a new oil filter and fresh oil after 1,000mls? I recall having a new turbo fitted to my old RS Turbo and a Cosworth back in the 90's and it was fine to use as normal straight away with out any run in period.
Any advice would be most appreciated after just picking the car up today and spending a fair wedge on it...

Hi Smuler, the total cost was £2846. Labour costs, 2 brand new turbos, new oil feed/return pipes, various exhaust and oil feed gaskets, fresh oil, oil filter, air filter. I used an Indy near Treharris after a recommendation from a car trader I know who deals in performance/prestige marques and has had 335i's with waste gate rattle sorted there previously. If you would like any more info/breakdown of bill etc. send me an e-mail on here...
