Originally posted by warmonger: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.
So your stock Duratec engine can handle over 400whp with no problem right? Because there are MANY turbo'd VQ30DE engines in that range with stock internals, some as high as 500whp.
Quote: 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.
Like I said, I loved my SVTC, it had a great engine that had oil starvation problems from the outset due to a bad design of the oil pan and oil return system. Luckily mine went for 88k miles with zero internal problems, many others have no been so fortunate on this site.
Quote: 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?
Yep, with a flatter torque curve and bone stock, not one modification as compared to your enthusiast modified engine. There are many, MANY, single and twin turbo VQ35DE's marching around now with anywher from 400rwhp to over 500rwhp in 350's with stock internals. Guys with built VQ35De's are running 700+rwhp now on TT systems. How many Duratecs are there on this site or any other vehicle site that uses a Duratec that have this much power and are still a daily driver? There are many 06 350's with mods that are closing in on 300+rwhp with bolt-on mods also.

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.
Yeah OK, now who's smoking crack? Show me the dyno graphs...and I'm not a Nissan fan by any stretch, this is the 1st Nissan I've owned. I've owned a variety of different model cars and I can appreciate each one of them for what they are. I never said Nissan didn't have it's weak points or problems, but I would never put the Duratec engine in the same class as the VQ series Nissan engines. If you haven't noticed, the Ward's 10 best engines does not have the Duratec and hasn't had the Duratec engine on the list for several years now, but I sure do still see the VQ series engine on there, wonder why that is?
