The VG30 and VG30DETT are a bit different in engine design, so to compare can be done but a stretch. As for the RB not being available in the US... That is grounds to discredit it? There are many things that have never been available in the US, such as the FJ and we all know that it is one of Nissan's best engines. What is allowed into the US is far more complex than just an engine's capability. There is a bit of politics and company finances involved to void that argument.
As for cost, that is an argument that is a dead end as well. Just because an engine is cheaper and can produce a lot of power, which by the way, a VG30E cannot produce the same amount of power as a RB26DETT, does not mean that it is better. If that was the case, we should all be repping Hondas. They are dirt cheap to build. Easy to build. And they can produce a crazy amount of power.
And the 300ZX being Nissan's premier car? Not really. The Skyline GTR and the current day GTR is their premier car. Always has been. Considered by Nissan, the public, and within the motorsport world, the GTR is what has made and continues to make Nissan's name. The Z series has been great and did heaps, especially with the classic Zs. But they are designated to a different platform.
As for comparing to the two motors, you are correct. Different design for different purposes and different markets. But you were the one who first brought up the comparison in stating "A single Turbo VG will make more horsepower and torque though!". I'm sorry, the VG is a capable engine and I love it. But the RB is in a different class and you get a lot more than the "oooo" factor with it. It can back up and has been proven to back up the numbers that it is more than just a pretty face. But, if you are basing your opinion of the RB based on the way I have decided to set mine up, then you are valid to a point. I have chosen not to reach for its full potential. I could have chosen a cheaper route to attain some of my goals. However, I was seeking a very particular goal and the VG30E would have solved it. I talked in length with Randy years about about doing a VG30E+T and a VG30DETT and it was decided against. And no, it was not because of the "oooo" factor when I made my decision.

silverton on 02:35:54 PM / 05-Jul-12comparing a vg30e to a rb26det is apples to oranges. comparing a vg30det to an rb26det is... well.... I think I've proved my point. The RB is a looker, not a performer.
It would be an RB26DETT unless you did a single turbo swap and your statement that the RB is a looker and not a performer is utterly ignorant. You should know better than making statements like that when it has been proven that the 2.6 is indeed an engine that was designed to perform.
As for your link, it's a bit of both. And it's based on opinions and some bits people have viewed in the past. They are upholding the capabilities of both the VG and RB but nothing that substantially upholds the VG30E in comparison to the RB26DETT. If you want to base your decisions on the VG30DETT, that's fine but being that I have stated the VG30E and you own a VG30E, I think it is appropriate to talk about that engine, not the VG30DETT. If we were to talk about that engine, then yes. The VG30DETT can outperform an RB20, is equal or outperform an RB25 (depending on build), and can equal but has not outperformed the RB26DETT on a consistent basis (again depending on build).
