Subrata,
I went through the same issue a year and a half 
ago, hoping to save time by using a seemingly 
reputable third party turbo specialist based in 
Florida. I regretted it severely, as my pump came 
back damaged beyond repair from obviously being 
dropped on the mounting flange. The company 
claimed the damage must have occurred in 
shipping, which would have required someone with 
an axe to attack and destroy the package. I 
refused payment for the work, and miraculously 
Pfeiffer came to the rescue and made it all right 
for me. I would NEVER send a turbo to anyone but 
the original manufacturer after this experience.
