Saw a post on migweb (vauxhall forum) regarding turbo choice on the c20let which is the turbo variant of the popular c20xe (redtop) engine. A guy on there was recommending grabbing a turbo off a Mitsubishi Evo - the TD05. Supposedly, not only are these way cheaper the Garretts but pack a lot of punch.
Anyway, here's the posts:

Anyone ever used these on a CA18ET?
