Where to buy 34mm flapper upgrade for 16g?

[X|Crescens]

I'm having major boost creep issues and would like to upgrade the flapper on the wastegate to a 34mm on my Evo III 16g turbo. The problem is where to buy it? I find websites that sell the modification only if you buy the turbo from them, but you can't just buy the 34mm flapper. I've searched and people were saying to buy it from WELCOME TO TRE   WE SPECIALIZE IN MANUAL TRANSMISSION REPAIR but I've looked on there and all they sell and do is transmission parts. Is there another place that I can buy the 34mm flapper? Thanks.

Oh good call, just found it on their site. Forced Performance Turbochargers: FP 34mm Wastegate Flapper

Thanks.

Port the turbine housing. If you port the turbine housing and a path to the wastegate you won't need the bigger flapper. The flapper alone may not cure your problem.

Slowboy Racing carries the flapper as well. A bit cheaper than FP.

It requires a little custom-grinding to get the sizing right in order to fit through the hole in the flapper arm, but old DSM intake valves work beautifully at a fraction of the cost.
