jx turbo on an aaz question

Post by Al Housman »

A mate(very experienced mechanic) is helping me to swap AAZ engines and is wondering if there should be a pipe from the vacuum pump to the wastegate on the turbo.
I did the original swap from JX to AAZ some years ago and cannot recall there being a vacuum pipe fitted. Not sure if it's a Garrett or KKK.

I have to admit to some ignorance about how the turbo works so any thoughts would be gratefully received. Is it possible that pressure to operate the wastegate is from within the turbo (if that makes any sense!!).

Thanks
Al
