Adjustable actuators

Recommended Posts

Im looking to fit an adjustable actuator to the new vf36 turbo i bought recently and im wondering what would be the best one to go for. I heard the stock one is pretty weak and doesnt hold boost well over 5k rpm. Anyone have some recommendations?

I don't know much about the VF36 but most adjustable wastegate actuators are just a universal part:

I've never even seen a VF36 because they were never sold in the US, but I would be reluctant to spend time and money on an actuator for a stock turbo. If you use a 3 port boost control solenoid and perhaps adjust the stock actuator a bit it's going to hold boost well enough. A stock turbo is going to run out of efficiency up top anyway.

How can you adjust the stock actuator?

 

I was looking to get an adjustable actuator as i need to rotate up the compressor housing so it bolts up to TMIC, the stock actuator will probably be in the way

will be sticking with the stock TMIC for now. i need to rotate the compressor housing so that the turbo inlet points vertical instead of horizontal so i can connect to the stock top mount. because of this the actuator bracket needs modification.

So went from this:

I came across this:

It looks like it has an adjustable bracket which should do the job and the actuator shaft looks like it has a bit of adjustment on it too.

 

My tuner told me to go for one that will crack open at about 1 bar

Nice if this works gimme a shout i've got a VF 37 to install and was thinking bout rotating the housing to fit on my HKS TMIC.

 

it does work,i know a guy on another forum thats done it. you need to change DP UP and headers to though for bolt on fit or else lots of custom pipework

 

modified actuator bracket:

Small bit of modification needed to connect to stock centre cat section with 3" DP

i love my forge awga; not sure if they have a model for the 36 though. but they are very serviceable (basically you can take everything apart into peices) might be worth a retrofit with a custom bracket, if possible. you can buy the 4-spring set and go from ~7 to ~25 psi.

so i got a chance to fit this onto the vf36 today and it took me a whole 10 mins to install, much easier to do when turbo is not in the car!

by adjusting the actuator tighter, you are essentially increasing the spring size, thus a larger actuator

 

 

there's nothing wrong with that turbo... it's just an oem size turbo. It's gonna run out of steam at the higher RPM's. A larger actuator will help hold the door closed, but you are running way out of the efficiency range. It's a flamethrower at that point. The only solution is a larger turbo

the main reason i got this actuator was because it can bolt on to vf36 with rotated compressor housing, standard one, i would need to modify the bracket which would be a pain in the ass.standard one opens at about .8 bar new one opens at 1 bar so not a huge difference between them
