Was @ Cobb to get a tune yesterday. My wastegate actuator was leaking on that evap leak finder test on the pre-dyno inspection. We shot 90psi into it and it wouldn't budge/open at all. Seems like the diaphragm seal is probably ripped. Everything else is sealed properly. My next question is what would be my best route to take.

Relevant mods:
VF48
Grimmspeed UP & BCS
HKS DP

These are the options I've come up with:
1. Try to find someone with a working bent style wastegate actuators that they would part with if they had it. (Really hard i bet)
2. Buy an aftermarket one. 80-200 bucks. (Is this even worth it??)
3. Save up a little, buy a Tial wg and have a shop weld my wastegate into the uppipe because I'm not gunna sell my current one. (But I will if it's necessary and I need to.)

Thanks, Ryan

If you are going to get anything other than an OEM wastegate actuator I would get the

TurboSmart Wastegate Actuator

a bit pricey but it is probably the best option for internal.

Cobb says they dont have the best luck tuning with the turbosmart EWG so I was assuming I should probably just not mess with getting the internal one. Not that I'm bashing turbosmart or anything, just following what my tuning shop says like everyone tells you to do.

You have two options: buy a new actuator or go EWG.

Some people who went the EWG route will try to sell their actuator on here so check around for one.
If you want to go EWG as well, buy an IWG bracket to keep it closed, buy a Tial EWG (38mm would be good for your turbo), and either weld a flange onto your uppipe or buy grimmspeeds 38mm uppipe. You'll also need a dump tube or some exhaust piping that runs from the EWG to your downpipe (in case you hate how loud an EWG would be).

Seems like I'll prob be going EWG but i really am trying to find a stock actuator because they will go for super cheap.

edit: Are there any stock turbo actuators that will work for the VF48? I think the newer WRX's went legacy style turbo but idk about the actuator. So, is there an actuator that will fit on the VF48 other than the 08-10STi?
