i was wondering if someone could give me a list of different parts from a monte that are compatible for a 94 z34...(specifically wondering about suspension; shocktower braces, coilover, shocks) and also anoy other performance parts there are out there that will work i am in desperate need to upgrade my baby.

pretty much anything suspension wise, as long as it's the same year, and pretty much everything else except the body from the doors back, and some interior parts

for a 94 Z, im pretty sure that suspension parts and brakes are pretty compatible on the Gen 1 luminas. You might have to do some modifying though, but they do work. Also, seats work, and many 3.4 DOHC parts from the 95-97 Monte's will work on the Lumina Z34 DOHC

strut tower brace.... anyone know of any that will fit.... thats what id like to look into getting now....

yeah, it should fit
