Vg30de will too fit, I'm in the process (I've kinda changed my mind now and want a vh45de, but I've lowered in a vg30de foam mock-up, height is the main concern, and it's really tight but it clears the strut towers), and a vg30et just requires a custom fabbed crossover pipe to be fabbed, the 300zx one interfers with thefirewall. But
www.club-s12.org will definatly get you informed proper.
