Title: weak k03 actuator
Post by: GTIcheeseman on 04 June 2012, 20:23

I have a k03 and was bored so was checking my car over, and I can move my actuator with my hand but with my k03s on my shelf that don't move so easy with my hand is that right? Or has it been worn out inside

Weak actuator isnt necessarily a problem, it stil opens and closes as it would if was new . However, when you run high boost levels with a stg2 the extra force put on the wastegate from the high exhaust gasses pushes the wastegate open as the weak actuator can't keep it closed. This results in boost tapering off artificially quickly at higher rpm. Fitting a forge or uprated actuator keeps it closed and more power can be made by the turbo.

With the turbo off it is.  Harder on the car as manifold needs to come off and the oil feel banjo.  Just leave that bolt out after ;)
