so was skimming threw the HOW TO for the evo x...stumbled upon tightening the stock wastegate 3 turns and it will hold boost better. it was a 20 min mod so i figure why not let me try it out.


MY own question is there is a lugnut and another piece connected to the bottom of the aculator. what do i turn? the rod itself or just tighten the two nuts on the bottom? im lost here

 

Take off heat shield at back. Tighten the rod itself. It has a retaining clip you remove, slide rod off wastegate and turn. start with 2 turns and reapply, drive see if you like and if car likes (NO CEL), then you can rince and reapply another turn if you wish.

 

the rod goes into the silver can looking thing on top.. oon the bottom of that rod are to lock nuts. am i removing that and turning the rod? sry im a noob

 

You have a PM.

 

just get a new actuator

 

Now can this be done on a totally stock car or are there mods that are recomended.

 

You run the risk of jacking up your actuator if you do this. It puts a lot of extra stress on it and will cause it to wear out prematurely. Also, if you tighten it too much, you can warp the inside of the housing.

Now if a bigger turbo or an aftermarket actuator are in your near future, then I guess it's not that big of a deal. But I have heard several tuners recommend not doing this.

 

first i have heard of it wearing out early. makes sense tho. are there any threads that talk about peoples failing?

 

I almost let this go but I could not. Tuners suggest not too many turns. That case would be, too much boost too soon, thus cel. As far as damage, its a spring! 1-2 turns is all thats needed to hold boost longer. Not sure on the amount of failed actuators that have been reported. Now a upgraded part and tune would be best, but hardly a part I'm concerned with replacing becuase of failure!

 

Are we talking 2-3 full turns?

 

couldnt you just put a manual boost controller in the line to the actuator and set it to whatever boost you care to have it open at? Seems a little ghetto to be tweaking the actuator on such an expensive car.

 

how do you guys undo this mod. im a dumbass and dont remember if i did whole turns or half turns.

 

I was thinking of trying this but to reduce boost instead. I was going to try loosening mine because my car is over boosting. If it will loosen, I will loosen it one turn at a time. There is a bobby clip so if I remove that, I will be able to simply turn the rod counter clockwise?

 

No you remove the bobby clip which allows the clevis to be popped off the wastegate arm. *Then* you can twist it to undo the turns, pop it back on the wastegate arm, put the retaining clip back through the wastegate arm, and finally tighten the clevis nut to secure everything.

The Clevis if you don't know what that term means, is simply the piece with the hole in it that you actually rotate to lengthen or shorten the actuator rod.

It's quite simple once you get in there. Just make sure you break the nut behind the clevis free prior to popping the clevis off the wastegate arm.
