HomemadeTurbo - DIY Turbo Forum

I was told by thermal99 that all of you here were a great help and knew a lot. I hope some of you can help me out.
I have a 2000 civic si that I want to turbo. I have rods, pistons, crank, sleeves that I have not installed yet.
Is it worth it for me to install all those items or should I just use my money on the turbo?
I'm looking to be in the 300's as for hp and I want to run between 8-15psi.
Also, I'm stuck choosing between a GT28BB, T3 60trim, T3/T4 .48a/r 46 or 57trim. It'll be a daily driver and probably won't see much time if any on a track... but let me know what you all think! Thanks~
