I just thought id let you all know, My vxr turbo has just come back from Turbo Technics for a warrenty claim the seals went after about 2 weeks when i was running a full milltex system with sports cats.
I only went for the 360 bearing but the guy from TTs said because of lack of back pressure you really need twin oils seals or else the seals will give < as they did after 2 weeks on a brand new turbo >.
So they have put twin oil seals in the turbo for me for free which im happy about..
Anyway he also told me the price is soon to go up for the upgrade of a 360 bearing and twin oil seals from £145+ vat to £225+ vat, So be quick and get yours sent off for the cheaper price.
These vxr turbos are a real pain.
