actually its an xo2 wastegate i got for cheap. just a tial knockoff but itll wor for now. what sucks is id like to leave everything as is, ut itll be too much heat in the bay. so the turbine housing and header will prolly get black heat coated and then ill wrap the manifold as well. need to weld an egt bung in it first though. ill do that when i have the rest of the stuff for my tig.
