I love my Z. Go to meet or show every weekend and work on my Z everyday. Im mechanic in military and work twice as hard on my Z (even when not needed) then i do i work because i love my Z. Ive made my decision tho. Sport 500 (only cause $1200 shipped & my stockers are beat up) and buy every breather mod possible with the ipp stage 1 block. Then couple years down the road if im not happy then i can upgrade turbo and have every thing else already needed.
