counter balancing adds unnecessery weight, which puts more stresses on the bearings etc etc

Here's some schooling for you on the history of the VQ:
Nissan originally designed the VQ for a European RACING series that never got off the ground in the early 90s. Shortly after, instead of scrapping a fantastic engine design they decided to start putting it in factory cars such as the Cedric/Gloria in Japan (which were TURBOCHARGED), and the Maxima in the US. The VQ is NOT a cheap, economy motor. It has the most stout crankshaft assembly of any production V6 in the world, has great breathing 4 cam, 4 valve heads, a very stout (as far as open deck aluminum designs are concerned) block. and a strong and durable timing chain setup that is hydraulically tensioned and requires no maitenence whatsoever. Furthermore, the VQ is currently Nissan bread and butter racing powerplant, used mainly in the JGTC.

The VQ wasn't designed to be put into many different vehicles...those vehicles were designed around the VQ. The VQ was around well before all the vehicles that it currently resides in were even conceived. The cost effectiveness of this whole operation is the fact that they put one fantastic motor design into 80% of the cars they build.

So why don't you go tell me again how I don't know WTF I'm talking about...

52 people responded to the poll (excluding the first and last two) of blown engines.

I'm sure there are even more people who havn't responded in regards to a blown VQ35.

Take it for what you will.

That's it, you take one of those out, and that's how a motor gets a new window or two.

In fact, the only thing OEM on this car is the physical block, and the physical heads. Of course both have been thoroughly worked over.
