I have a Tial MV-S wastegate in black that I used on my car for about 4,000 miles.
Functions 100%, and come with 4psi, and 15psi springs. Both are currently in the valve making it a 19psi WG pressure.
Comes with all banjo fittings, and dump side flange. New manifold-side flange will need to be purchased($15 from extremepsi.com).
Looking for $190 for the one that is not scratched.
SCRATCHED/FADED VALVE IS SOLD.
