I'm planning to upgrade my turbo from ct9b to a better flowing one. I've heard people using hybrids, k1-200v and td04 with plug&plays, but are there any experiences with other turbos? I'd like to try something different than the usual ones, but don't wanna be the first pioneer here. Fast spool time is essential for me. I've heard good about holset turbos, but they might be too big for 4E?
