Hi guys I'm Nearing the end of my erst build it runs spot on but it doesn't sound like a turbo as if there's no boost when I Rev it , so reluctantly I fitted a dv to see if whom tooshed nothing boost gauge is just showing vaccum only the waste-gate in the housing was pretty stiff so I changed it for another witch moved freely still nothing I've looped the turbo bleed valve Amal valve nothing changes only thing I can think of would be the actuator itself is a -31 from a cosworth and I never bothers changing the length in it ? Is there any difference ? I'll await the sarcastic comments
