Just fitted a new turbo to my GTE. Got it built.Specs are as follows: T04 plain bearing casing.Vl turbo comp wheel and cummins turbine wheel that has been back cut.The comp housing is vg30 and the exhaust housing is an rb 50 a/r.
Made strong to handle high boost this turbo combination is awsome.It is at full boost by 3000 and holds good all the way.
My boost was set at 15psi and jumped to 17psi with just fitting it. I have wound it back to 15 till I can get it tuned then some bigger injectors water 2 air and 20 psi are in order.
