does anybody know where i can find a heavier internal wastegate for my aps single turbo kit, i think i have a 6 or 7 psi one now but i want something heavier. my mysterious boost loss issue was partially resolved my tightening the actuator rod all the way down but it seems like the issue is coming back. i think i just need a heavier wastegate. any suggestions guys?

 

I thought torquefreaks was supplying the upgraded ones for the APS TT kit. Check them....or call Garrett.

 

torquefreaks does sell upgraded actuators set to a base boost of 10psi.
I bought two for the TT;however the pull arm may need alteration for the ST use.

 

i figured i could just unscrew my arm and put it on the new one. will that work.

 

kinda looks like it will. The waste gate throw between the TT and ST are similar.
