waist gate from s4 to s5

waist gate from s4 to s5
well the waist gate arm is different from s4 to s5 because of the way the manafold is. i've found this on my own.
the s5 waist gate arm is bent.
the s4 arm is not. its straight
well i have an s5 waist gate, its arm has threading on it with a odd looking long nut that links between the threading on the arm. apparently its slightly adjustable.....
i also have an s5 waist gate and its arm does NOT have this threading but it has the same bend in it. and it has the same part number on it.
i dont want the adjustable one any more, because i dont like how the previous owner adjusted it to "hold" more boost (doesnt really hold more. just doesnt let boost out as quick)
i dont see why these 2 different types of s5 waist gates are not interchangable.
i can supply pictuers if some one wants me to post up.

well ive personally never heard of a stock turbo with an adjustible actuator arm, but then again i learn somethin new every day. did you try to switch the 2 already? how do you know that they are NOT interchangable. all you should have to do is unbolt the actuator (2 bolts) and swap.

its funny though. the WASTE gate with the adjustable link has a different sufex to the part number then the one with out. on a 2nd line.

oh ya. the whole turbo is taken apart cuz i am changing out the turbine from my s5 ported waist gate and runners. kinda popped that turbo's front main seal. oil everywhere!
and i have reason to believe its cuz my boost spiked to 12 alot because of that adjustable arm, the previous owner of this said he did adjust it..... yuck.

Yes, it's not stock.
It's not that hard to make it adjustable like that.
Cut rod in half...
Cut threads into the rod with the proper dies...
Insert turnbuckle...
It's an old-school trick before MBC's were popular.

This has NOTHING to do with it being from Japan. Adjustable length wastegate actuators are common all over the world and have been around for decades. You think the Japanese inventing modifying cars? You must be very young...
did i say it was a stock "jdm" thing? no...

hey, here is something that is "somewhat" related.
are the S4 and S5 waste gate actuators interchangeable?
i ask, because hks sells and adjustable S5 actuator. i would like to put
this on my S4 bnr hybrid.
NZ, stick around this thread. i have a feeling you may know this right off the bat.

Nope, as mentioned in the original post, the arms are different because of the different wastegate location.
You might be able to get an S5 actuator to work on an S4 turbo by bending the rod so it was straight and redrilling the hole at the end to suit. That's pure speculation on my part though...
