Wikipedia states in their VG30E section that the Mercury Villager VG has been "modified to become a non-interference design." What does this mean exactly? Does it mean that I can't take the motor, an drop it into a 300zx?
ALSO, I was wondering if it was possible/done before to take the VG30E and convert it to a VG30DE? I've read that they both use the same block, but have different heads, and I'm sure slightly different belt gearing.

From what I've been able to tell, the bore and stroke of the Quest/Villager VG is the same as the other VG's and they made it non-interference by reducing the amount of lift of the cam, which is why it is produces less power.
Everything else should be the same, so if you wanted to you should be able to put it into a Z.
Definitely not possible to put a VG-DE head on an VG-E. The simplest way of explaining it... the VG30E(T) uses 13 bolts per head to bolt to the block while the DE(T)(TT) uses 8. From there you'll have oil and coolant passage differences.
The 13 bolts per head is one good reason why the VG30E(T) can handle so much power. Rarely do they pop headgaskets.

Alright, then the Quest/Villager motors just need new new cams. Easy enough. I was just worried that the wouldn't bolt up into a Z.
I have another question; Because I've never seen a VG30ET(or the VG30DETT) in person, I was wondering why they didn't put a second turbo on it? Also, would it be possible to TT a VG30E? I did a forum search and only got TotalJDM's advertisement post.
Also, will all the VG30 trannys bolt up to each other, or do only a certain year models work fit o certain engine year models. As well, Would a VQ transmission work on a VG? Reason being is I got my hands on a free VG30 motor from a villager, but haven't acquired a transmission as of yet, just wanting to know my options.
Thanks for clarifying my head questions, and thanks in advance for these new questions.

Yup, you should be able to put some different cams in there... you will lose the non-interference design though so be sure to keep up with the timing belt.
You can definitely twin turbo a VG30E, its just all custom fabrication. As for a reason why they didn't... I really have no idea. At the time, for the power they were making a single turbo was definitely more than enough so that could be it.
At the time, the twin turbo setups were possibly used for slightly quicker spooling. Probably the biggest reason though... for V engines twin turbo setups are a little easier to setup as you don't need a crossover pipe like on a single setup.
I believe someone is currently working on making twin turbo manifolds for the Z31's but I'm not sure if its ready to sell yet or not.
transmission wise you can pretty much use any transmission from the VG's, they all had the same pattern. The strongest one you can get is the Z32 5-speed. To make that one work on a VG30E you'll need a 89-91 Maxima flywheel, Maxima or 84-86 300ZX clutch kit, Z32 throw out bearing, and the Z32's starter.
Now, I don't know if anyone has done that transmission swap on a Z31 yet. I did it on my M30, which had the starter bolted to the transmission like the Z32 so there was plenty of room in the transmission tunnel for it. The Z31's starter is mounted next to the block so there's a possibility the starter won't fit in the transmission tunnel. You can modify the tunnel for it to fit if need be though.
You can also use any Z31 transmission. The 87-89 Turbo being the strongest. The 84-86 Turbo transmission is a Borg Warner T5. They are generally a bit weak but are used in so many different vehicles (most notable the early Mustangs) that there are quite a few performance shops that build the T5's up to handle some serious power. The 84-89 N.A. transmission is generally considered to be pretty weak but depending on how much power you make determines its life.
The 87-89 Turbo transmission tends to be a bit difficult to find but if you do, it uses a 250 mm clutch setup so be sure to get the correct pressure plate and clutch as the rest of the Z31's use a 240 mm clutch setup.
If you go the Z32 route, be sure to get the NA transmission as there is a very slight difference in the bell housing that will likely cause issues with the starter when you use the Maxima flywheel. I haven't confirmed this, but most say that is where the difference is between the TT and NA bell housings.
If you have anymore questions, don't hesitate to post them up!
