hey guys i got a hybrid t2 turbo on my car and the boost doesnt come on till late in the revs about 3.5 - 4000 revs.ive taken the turbo off and theres quite alot of play side to side but none in and out.theres also hairline cracks in the exhaust housing and theres very very slight chips on a couple of the exhaust proppellars(sp).any suggestions?cheers

 

what size exhaust housing has it got
what actuator
the exhaust wheel blades should have NO chips out of them
the very small hairline cracks wont affect boost

 

i dont know how do i find out?the actuator is uprated i think but im not sure which one it is

 

In the inlet of the exhaust housing where it bolts to the manifold, there will be numbers.
They will be hard to read, and need a clean up to do so.

Its possible you have a much larger exhaust housing than required.
Or the actuator is suited to the turbo correctly.
