I have a 4x4 cossie turbo.

I was running stage 3 and run 20 psi on T3.... boosted ok then went tits up.

lost all boost and now will not boost at all.

We have taken off the inlet and down pipe, and the bit inside is spinning with no probs,

when you drive it there is a nasty noise around 3000rpm where the turbo should spin up. and only when the turbo spins up.

We have taken the actuator off and reved the car and its fine no noise its only when the turbo is connected.

Does anyone have any idea whats wrong what it could be, we have tried it all

all blades on the shaft are fine and the shaft has very little movement left and right and none backwards and forwards.

your help is most needed.



Oh and i have checked all boost pipes and there are no air leaks !
