why would you want to though?? A gtm Z makes 480-520 @ 10psi, a gtr needs 14psi to make about 460 and thats with the extra displacement. So there is nothing special about that setup that it would be worth the money. The tranny and the drivetrain is what rewrote all the record books though

That's true, but the the VR has the better reliability because it was designed from the ground up with forced induction in mind. Not saying the VQ isn't reliable, you're just taking a bigger risk and likely decreasing overall engine life by going FI.

Nissan has just fitted a GTR engine in to a Juke body,lets hope they can put 1 in to the 370z body,w/o the 4WD.

The Juke R looks sweet! It looks like they've completed the conversion but they haven't put out any videos of its performance...I can't wait to see how it does.

My thoughts exactly. It's the drivetrain and tranny that makes the GTR so amazing. Sure you can match the GTR in HP but you're not going to put down that power like the GTR does.

Yep, on street tires the only way to keep up with the high HP AWD cars from a dig is to be in your very own high HP AWD car!

The ZR1 is bloody fast in a straight line, but it needs more than 1/4 mile to be able to beat a GT-R. It traps quite a bit higher than Godzilla but it doesn't have enough track to pass it.

I seen this race happen in person. The ZR-1 does nothing in the quarter mile. It will take a one mile stretch for the ZR1 to make the GTR look weak. At around the half mile mark the vette superchargers kick in and just take off on the GTR making the GTR look underpowered and worthless. But who races more than a quarter mile on the drag strip????
And on a track? I think the GT-R will take a ZR-1 as well.

that is not how a supercharger works. that's the point that the power-to-traction ratio starts to favor the ZR1 where it isn't spinning but is able to put down the extra hundred horses in a much lighter car and pull ahead. up until that point it's fighting with traction control (or launch control really). as the R35 GTR creeps up in hp every year, i'd be curious to see how it stacks up it's last year of production. if it's pushing closer to 600hp it might actually stand a chance of beating the ZR1, if not it'd be damn close i'm sure

I'm not really sure it will take a full mile. The two cars are usually within a car length or two at the end of the 1/4 mile, with the ZR-1 trapping a few MPH faster than the GT-R. So it would start to pull it beyond that point. I'd say you only need a half mile stretch.

And whether anyone races like that or not is beside the point. It's just a hypothetical comparison.

They are close, for sure. The GT-R is an amazing car on the track. With its suspension and electronic controls it just defies physics.
