depends which one and in which form your talking. I went from a vg30eT to a vq30de, basically, I had a single turbo 300zx and my I30 would spank on my z31 all day long, and not just because it's a 5-speed and my Z was an auto, when I had my Z my mom had a '99 i30 auto and the z definitly couldn't take it off the line or on the highway, I'd say the only vg that's better is the vg30deTT, the twin-turbo Z32 300zx is still; hands down; way faster and more mod freindly than a Z33 350Z/G35

First of all he did not list the turbo engine code. Second of all the N/A version SUCKS and is SLOWER than our family sedans.

How cheap could developing a new family of V6 engines with microfinished internals be? Assuming this R&D took place from '92-'94 they designed and built the engine that is carrying them as a company when they were in some of the worst financial conditions they had ever faced (peaking in 99-01).

VG30DE in it's defense has a very solid block and internals which shared with the VG30DETT. It has different pistons as well as different cams from the VG30DETT, but, engine only, are pretty identical otherwise. It comes with equal length intake runners as well as dual 60mm throttle bodies. It's draw backs include it's size and weight as well as its high cost.
VQ30DE in its credit has a fairly broad torque curve that is effective even at low rpms. It is of a much more economical design which is has proven itself with rock solid reliability. If I remember correctly, the VQ also uses a serpentine belt in conjunction with a timing chain, where as the VG uses a huge crank pulley with individual accessory belts and a timing belt that need replacement every 60K.
Edit: Cams are same. Heads are different.

Even if your friend was telling the truth, it's not like the USDM VG30DE is going to fit in your maxima. You are going to run into some BS trying find a bellhousing to adapt to the VG to a Maxima transmission. Also, the VG is quite wide as it fit quite cozy in the 300zx engine bay.

makes tuning easier toIf I'm not wrong, his compression is still 9.41, not much down from 10.3 considering the VG30DETT went down to 8.5
