View Full Version : uprated actuator on zlet turbo
Will the courtenay uprated actuator for use with the VXR turbo fit the standard z20let turbo???? im going to change to the vxr turbo soon but my standard atuator is ****ed, seeing as i need the uprated acuator to run the vxr unit could i buy and use that untill i decide to swap over to new turbo???? im currently running eds phase 2
It certainly will fit, If you had the stock blower right next to the VXR blower, you could not tell the difference, apart from the water feed of course.
It should work, but beware that the uprated actuator is a 1 bar unit, and may make the car a bit restless and boost a bit uneasy. I am running the same software, but have already fitted the turbo and actuator, and it can be a bit like all or nothing when it comes to the boost, one minute, all is fine, the next, its hedge here I come:omg :cheesy: . I am having it remapped again on friday, so lets see:cool:

dus the uprated actuator give major difference? when i had my turbo RR'd on saturday i asked what else they cud do to improve it BHP wise & they said probably chip it & uprate the actuator...and plan on doin sumthin like that over next couple months.,.,.

the standard vxr actuator has a similar pull weight to the zlet actuator, though its slightly stronger. the vxr blower and actuator run perfectly fine on a standard mapped car.

so will the uprated courtenay actuator be needed for eds phase 3 or will the standard vxr actuator be up to the job ????
Ive been told that after fitting the vxr unit whilst on a phase 2 map there is a noticeable difference, is this true

well for a cs3 upgrade u need an uprated actuator for the vxr blower.
The standard VXR actuator is actually stiffer than the Courtenay uprated one. It does have a longer stroke than the stock VXR one, but all that means is that it reduces the cars capability to drive and cruise off boost.
Regal state that the VXR actuator would be capable and suitable for use with a Phase 3 setup, and I can well believe it. I would be tempted to try it again on mine, if I hadnt sold it:redface:
I have a spare new actuator off of a Regal hybrid turbo if anyones ever interested (its not uprated)?
**Unless Andy talks me into fitting it!**
Haven't you fitted that Tim, I thought yours was knackered ??

Its not a difficult job to do tim, however it is made a bit more tricky given that your rad is spaced back due to the side mount IC. TBH, the most awkward job is getting the manifold cover off. The turbo water feed jacket pipe has a locating lug on it, which can be bent out of the way so you can release the actuator, there are 2 bolts holding the bracket to the turbo body, which are easily removed with a 8mm (i think) openended spanner, all you need to do then is undo the 6mm nut (using a 10 mm spanner) on the wastegate arm, copy those settings over to the new actuator, and put it all back together.
Access to the underside of the car is an advantage, but it can be done from the top. If I remember right, didnt Ady Jones change one in the Regal carpark on the AS rolling road day????
Hmm cheers Andy as this will be most useful. Think Andy Jones fitted his at another stage but i may be wrong. Will consider this now then - thanks.
sorry to be off topic, but does anyone know the right amount the actuator should adjusted, ie. how much is sticking out of the bottom?
Think its about 3 threads as standard.

the vxr has about 7-8 threads showing on the actuator rod.
