what wastegate size?
 

Hi, I just recently purchased a mk3 supra. I have started to mod it already and was wondering what size wastegate I should use and what brand is the best. I have a gt40 turbo, 680cc injectors, Blitz Nur Spec 3" cat back exhuast and 3" downpipe, stainless steal turbo manifold. Any help would be appreciated. Thanks
