Mine was doing nothing and it was locked up. Here is a simple check to see if it
is locked up before you go cranzy on everything else. Remove the intake boot from the
turbo and see if the turbo still turns. If not if is locked up. As far as the other one goes
it can have some side to side movement on the turbine shaft and should have no
in and out movement. Also check if the actuator moves freely. You can disconnect the
actuator and see if the nozzles are free. If not you can take the exhaust housing off
remove the veins and glass or sand blast the internal parts and reassemble with new
stainless bolts. Center section can be rebuilt with t-25 kit if needed. If you check
side to side play put a little pressure and turn the wheel and make sure it does not
rub. If it rubs at all it is no good, needs new bearings.
You are going to replace it with a Mitshibishi??? Why not a t-3, or do you already have
the mitsh? I think you will still have to change the manifold. I am pretty sure Mitsh has
its own manifold. Are you getting any boost at all?, or does the guage just stop dead
at 0psi. Your veins might just be stuck closed. Check all your vacuum lines going to
the actuator. I am no Vnt expert, this is my first Vnt car, but it seems hard to get any
vnt help anymore. Let me know what happens, also let me know if you want to seperate with one of those Vnt's. I am doing an experiment with my spare turbo.
I want to adapt a T03 intake housing and impeller to the Vnt center section and exhaust
housing I just need a good vnt turbine shaft.
it has to do with the ring gear rollers that allow the ring gear to move freely.Heat shield?????
I disassembled the exhaust housing, removed those rollers and the ring, glass peened
everything and reassembled. Did a little hand finish on a few nicked blades and other
high spots. I lost one of those rollers and had to make a new one on the lathe. Also
note that most of those parts are stainless, except for the ring, pins and the main body
that holds the blades/veins. The rollers are actually stainless. Check with a magnet, you
will see what I mean. I will post a picture of the inside of my exhaust side before and
after. Later this evening. Note, all three of the bolts holding the blade assembly snapped
off on mine when loosening, I had to drill them all out and replaced them with stainless
