Alright I know there are a tone of forums for this already I’ve read just about almost all of them and I still can’t make a decision on a good turbo for the build I want to do. I have a b18b1 ls block with a gsr head and I’m looking to hit about 400 to 450 hp safely. Any thought and or suggestions?

You'll need to continue to search (and ask in the correct forum. ) So, No. Lots here. Take your pick and go from there.
