I thing my internal gate is going bad and possibly needs to be rebuild or replace. i have a TC59 turbo with the old HKS exhaust (bolton) housing... the wastegate was initially from the old HKS bolton turbo. turbo is not holding boost... there are no leaks and i'm using an EVC. i even shammed the wastegate and no luck.
where can i get a new one? and can i use any others...
