Nissan GT-R GT500

^ they were removed for being expensive as well, and for being rather heavy

Again, i say this

Emission Standards: Japan: Automotive NOx and PM Law

In 2002, Japanese's emission's laws underwent a huge scrape, Nissan then just went to the VQ engine. Why do you think the Skyline never came to the states? "beacuse it was to heavy"

It was beacuse Nissan could never dream of beating US. emmision laws.

There are three cars on the page i posted, There is a Z and an R32 with twin identical turbos and then there is a third Z that is not pertinent with the discussion

I see what you mean now, but it doesn't change the fact that it is still a VG30DETT, not a VQ engine.

The Z as you have noted makes more torque, but the cost to power ratio is not identical to the r32 e.g.
The Plumbing difficulties for the turbo must have been enormous. Plus all the torque In the Z and all other VQ30's tuned in a similar manner have the torque jammed up in the low end, Making the Z burnouty. Torque is supposed to be through the whole rpm band in a properly tuned car.

Both curves are near identical, they both shoot right up. And by the way, that's not indicative of anything really, as they've both been short shifted up to their top gear, then have been run right out to the limiter. You're right that torque should be spread through the whole rev band, by having it make as much torque as possible early in the range and not dropping off at high rpm. There's nothing wrong with having a lot of torque down low, you can just gear it longer in that case.

Not to mention the nightmarish turbo setup that made LHD conversion difficult.

you're kidding yourself if you think emissions was the only reason. Nissan themselves said it was too expensive to keep developing the engine, and too expensive to build in large numbers. and yes it's heavy, you think that strength comes free? it wieghs 324kg, and being a long engine it sits out. the VQ is shorter and lighter (but weaker). or did you think nissan adopted it for kicks
:

The previous Skyline GT-R LMs had used the trusted RB26DETT Inline-6 motor, but the design was old for a racing car, employing an iron block which added weight.

no, they totally should have kept it.

no no man emissions is the only reason
