Im building my B16 on my 2000 Civic Si, building in it for turbo with forged internals and all that good stuff. i have 550's and have been advised to use 1000's, with proper tuning will 1000's make a difference good or bad? building for safe daily driving, well to have fun without worrying of blowing!!

 

Great way to start. Wrong room. Before you get torched, do some searching about your question before asking obvious questions. Have fun.
