all turbo companies are the same
my brand new one failed after 1000miles, they said it was becuase it was on a fresh engine build and i needed a pre turbo oil filter
so bought another turbo off them with inline filter, fired it up there was a rattle thought it was aux belt tensionor, i do less than 20 miles and the 1st time i boosted up to 14 psi the turbo siezed solid
there excuse was my car ran lean and siezed the turbo up
turbo companies are wankers full stop
