So its all relative.



The VQ35DE rev-up engine with the new cams is dyno'ing over 250rwhp in the 06 350Z's bone stock. Add Nismo cams, intake, and exhaust (similar to the scenario you outlined for the 3.0L Duratec) and the numbers only go higher. And MANY people have tuned the VQ30DE engines well beyond any Duratec engine without having to replace stock internals.

As a former SVTC owner, I loved the Duratec engine, but I wouldn't put in the same class as Nissan's award winning V6 lineup for 10 years running. Just my .02. And in short order the next gen Nissan V6 will be out, and it'll trump the competition once again...



You joker, I tuned my STOCK Block duratec with stock internals to well above any normal engine and at least to levels as high or higher than any stock nissan engine can handle. I won't say its better but it isn't inferior by any means. The SVT 2.5L engine was award winning in the years 10 best engines in those short three years it was made.
It was making 200HP out of a 2.5L when nissan was making 222HP out of a 3.0L.

You're talking about a 3.5L in their top of the line sports car dynoing what, only 15HP more than some of our home-built enthusiast engines?

Go smoke some more of that Nissan tailpipe. lol
If Ford would make available some higher performance cams through their motorsports division then things might be even more dramatically in the our favor.
Instead we have to rob parts from commuter cars to NEARLY equal the motor output of a Nissan sports car motor. Imagine if we had some race designed cams.....

And have you ever compared the dyno of a modifed 3L with the nissan 3.5L in the Altima/Maxima? The Duratec with SVT cams is so much broader and flatter.
