Test drive one, or an older GT3, if that's possible, so you get a feel for what you are aiming for. In a Z, you will never get the engine sound and forward visibility that P cars offer. Things to get you a little closer imho...
Bolt on and tune (add some power and get rid of the throttle lag)
Aftermarket clutch and lighter flywheel (rev feels lighter but may throw off the S mode)
Short throw shifter
Improve oil, trans, diff cooling
SPL bushings
SPL arms
Hotchkins front sway bar
Coilover/dampers/spring upgrade - that's a maybe
Reduce tire stagger or square setup, stickier tires
Brakes - BBK or 2pc rotors with pads/lines/fluid/Ti shield upgrade
Other things to make it more bullet proof like ATI engine damper, insulated clutch line, CJM oil pan and fuel pump, new MC and CSC or CSC Delete.
Weight loss would be lovely, maybe a lightweight battery, remove the spare tire, light weight seats. Other than that, the Z is stripped as is, i wouldn't take out carpet and trims if GT4 is your dream car, imo.
