Hmzz.. Had it on my 2 litre ZVH and it pulled 1.3 bar till 6000 rpm and now it's already on 0.8 bar at 4500-5000 rpm.

turbo is quoted on 28 psi but i think that's for a 1600 engine.
Just wondered if it's becuase the turbo is on it's way ( 2 mm radial play and 0.5 mm axial play ) or it could be something else.

I'll try a 2wd cosworth t3 next weekend if all goed well so then i'll know for sure but if it could be something else i could try it before i swap turbo's.
Have to get something else anyway to run 1.5 bar to about 6800 but till i get that just want to know if it's really the turbo that's causing my problem.
