Yea usually people like lower compression on turbo setups (8:5.0 or 8:0.0) because they elieve its safer. Personally im a fan of high compression and boost. i know someone running 14:0.0 compression on low boost with a gt30r i believe,putting out 600HP.
Do your research, their is no such thing as to much research. For example the FAQ in the forced induction forum is a sick layout and will help you understand what you need etc.
I'd also have a goal in mind bc then youll know what your aiming for and wont be shooting in the dark if you will.
MOST IMPORTANT!!!!! is the tune. Its ALL in the tune so dont cheap out when tuning.
