I've read a couple of eg33 turbo threads, it's not that bad to do. The EG and EJ's are similar, but you still want check what works and what doesn't. Not everything does. The SVX's only came in auto, and it wasn't built to handle the NA engine even, They go out all the time. Maybe some of the manual EA boxes fit up? and can have the front's welded up. I don't really recall those details.
