I crushed my stock wastegate on my WRX turbo and can't find another for anything. How would I make it to change to a external wastegate? Just weld the flapper closed and weld on a flange for the wastegate? If so anyone have any pics and a HF mani made for an ext wastegate? Yeah I know it ghetto but I gotta work with what I got! Hell this is HMT isn't it? Maybe thinking of using a older audi 5000 ext wg?
