Sourcing a External Wastegate Spring

[Chereboy]

Hey all, I'm currently having issues with my external Wastegate Spring.
I am Currently running a stock 7 pound spring in my HKS External Wastegate. I believe it to be a Standard HKS External Wastegate but cant find anything anywhere to help me source out a correct spring. My reasoning for this being that my previous wastegate diaphragm tore and I was in need of a new one so I came to this Site seeking help and what would you know, I was sent in the right direction to purchasing a replacement. I ordered a "HKS STANDARD WASTEGATE REPLACEMENT PARTS - DIAPHRAGM" from RHD Japan and due to the "Standard" one being a perfect replacement I'm currently under the assumption that this is the name my one goes by as the only other one I can find is the GT II.
I recently purchased a 0.6 to 1 Bar Spring from RHD Japan. I purchased their "HKS GT WASTEGATE SPRING - WHITE BLUE" thinking that it would suit my Wastegate as at the very least it is just labeled a "GT" and not "GT II" which  can see a photo of on their website and confirm that they are not the same, but I could not have been more wrong. 
Below are some photos of my current Wastegate, Wastegate Spring and the new Wastegate GT Spring I purchased
If anyone could please help me with any sort of information on where or how to get a spring more suited for my application without changing wastegates would be greatly appreciated.
Thank you

So, first thought is. Contact someone who sells HKS stuff, for example - www.carmodsaustralia.com.au

They import stuff from Japan regularly and obviously can get HKS parts. They can probably help you out. 

Next thought is speak with a company that deals with turbo stuff as their core business. There might be some cross over with say a turbosmart wastegate spring and your HKS one - gcg.com.au comes to mind as such a company. 

Last resort, your going to have to learn Japanese, fluently. Fly to Japan and visit the HKS headquarters and beg for a wastegate spring. They might take pity on you and supply you with a spring.

Ahaha, thanks for that, I never thought to contact a turbo supplier and didnt know car mods sold HKS Gear. Ill definitely contact both and see if they can also help me out, otherwise I've always wanted to go to Japan so thats works too I guess.

Edit: Neither Car Mods nor GCG have anything to do with HKS, ill keep searching though

Personally I would replace that wastegate, if you're really wanting to stick with that one for period correctness then I would try contact Turbosmart.

Judging by the photos, a Turbosmart spring might just work.

Saves you from the HKS tax and international shipping.

That's bizarre, they have HKS stuff on their site =/

Did you ask GCG/Turbosmart if they have a spring of the size you require?

If you're not having luck over the phone, you might have to visit your local Turbosmart dealer in person and bring the gate/spring with you to size up. People tend to be more helpful in person.

I remember this, pointing you to the torn diaphragm and which one to source. Your gate is the HKS standard not GT or GTII - unfortunately your HKS gate is discontinued and so are the springs.

All you can do is measure the od of the existing spring and try and get something compatible. The lengths will slightly change but whatever, they have to.

Here's the part numbers for you. Google them and you might get lucky with someone with old stock, although I don't see that a 1 bar spring was ever available for it.

Appreciate you helping out again, ill have a little look around and see if i can find something with this information otherwise im thinking of just blocking off the port where the screamer currently is and buying a new wastegate that can bolt onto the 2 bolt flange currently there and bolting my screamer onto the output of the new wastegate and getting my screamer pipe extended so it sits under the car again as it will be raised up quite a bit
