Turbo Trims

I am rebuilding my T25 turbo and was wondering if I should change the trim? Is there a better trim out there that can make better horsepower? please let me know guys. Thanks

Ick, that's a pretty involved question. Check the se-r-list.org mailing list archive. Your answer might be there. Search under turbo trim and Rob Cadle. It might take some time but I'll bet you can find your answer there.
