Hey guys. I have a 47mm older style trust wastegate with a 1.2bar spring. I'm trying to lower the boost to around .8, but I'm having a heck of a time finding a lower rated "trust" spring. Does anyone know if the greddy springs or anything else for that matter will fit?

I'm also having trouble finding dimensions for other wastegate springs, if anyone knows theirs can you please post it as I might be able to find a suitable replacement.

Trust 1.2 bar wastegate spring dimension:

Outer diameter: 1 5/8"
Inner diameter: 1 3/8"
Height: 3 1/2"
6 active coils

Thanks in advance for any info
