Haha, yes, I live on a mudslide hill and breath in smog. Very close minded arean't you (oh yeah the 03 is the fastest G35 EVER). I suppose you wouldn't go to southern states because they get hurricanes once in awihle I don't eat fast food by the way and I've not sued anyone in my life, to many ignorant statements in 1 sentence, I had to answer back.

I've not been to the track with the G yet, but I have a good idea of what she can do, and if you were in Cali and going to the track, I'd go out of my way to make it there just so show you up. When I have more time and not so busy with school/work/life I will get there, probably during winter break.

I am a terrible driver , and you know what, I would still romp on you at the track. I don't need 150 1/4 mile passes, I just need 1 time. Sorry just getting tired of your undying support for the 03 engine as if its gold, you've beaten this to death saying how the 03 engine is under rated, do you think it really matters that much? If you love your engine so much, good for you, get over it.

 

#1 - 03 vs 04 and 05 - It was the lightest of the bunch but also dynoed the least.

#2 - DaveB you have yet to dyno your car. Dynos prove the 03s do not dyno as much as 03.5-04s. Track times can change from weight to weather conditions. So this is not a very accurate way to tell if the car has the same power as the other years.

 

I agree Nick about Dave and the 03 engine. It's because he owns it, and its the best. IMHO, my 04 was faster to 60, than my 05 is. I owned both years and both 6mts. But after 60, its all over for the older G35s period. This one pulls extremly hard above that.

But dynos and research in the past have proven the 03s are the weakest of the G35s ever made. You can't deny that.

 

It's called sarcasm hence the reason I put "j/k" at the end


Well if you were in Kansas City I'd help you achieve the best performance you can out of your 05. I really don't understand the attitude or the trash talk on your part.


Sorry, I'm just trying to get guys to have a more open mind on this site. Way too much information on this site has gone unchecked, taken as Bible, and gone unquestioned. I'm in no way way saying the 03 is the best. I'm just trying to show that's it's not the dog everyone thinks it is. I've even given factual data, references, and my own personal experiences to support my claims which more than I can say for most of the information on this site.

 

Sad to say Dave but there are many many others that have posted much better information than you have in the past. We don't need to bad mouth the site or the users here. Everyone gives their share of input. Some might be way off and some might be right on.

DaveO gives the best info and most technical knowledge this website has to offer. I will have to say he is probably one of the top ones on the list for that and he has been here from the beginning.

 

I'll probably never dyno my car. I don't see much point plus the track gives me the information I need. My friend, same one that ran a 14.7@96mph, dynoed his stock 03 5AT and saw ~218whp/212wtq. This is the same dyno you ran on with your 5th gen Maxima.

My only weight reduction mod was no spare tire.

I know that ambient weather conditions have a huge impact on track times hence the reason I calculate the density altitude (DA) for all the days I've run at the track. Here in Kansas City we see huge shifts in weather and it greatly influences the car at the track. I've seen differences as high as .4 seconds and 3.5mph because of weather. This is with no changes to the car at all. The only time I've run my G, the conditions weren't horrible, but they weren't optimal. The calculated DA was in the neighborhood of 1700-1800' above sea level. Now if my G's VQ performs anything like my Maxima's VQ did in cooler air, it may shed .15 and gain 1.5mph in trap speed. We'll see when November comes around and I can run in dry 50 degree weather.


I think you'd be severely disappointed if you actually applied Cartest to a 04 6MT vs the 05 6MT in a race from 0-120mph. Look at the dynos between both cars and you'll see that the only place the 05 high-rev motor holds an advantage is in the last 800rpms and the average gains across that area is a mere 10whp or so. Then look at the power that traded in the low/midrange. You know as well as I that midrange power is where most of your acceleration is generated. How long do you really spend accelerating from 6200-7000rpms in 1st, 2nd, or 3rd? That 10whp advantage won't play out till 110-120mph or so. Now if the 05 high-rev motor made an additional 15whp across the whole rpm range, it would be a significantly faster car. Most of the reason Nissan kicked up the power on the 05 6MT is because HP sells cars. 99% of the people don't understand that area under the curve is what wins races not peak HP.

 

Easy.... hahahaha, only if you've got DaveO to figure out the wiring and custom fab your mounting brackets.

... thanks DaveO!!! - T

 

I'm sure others have posted better information and I'm not bad mouthing anyone. Everyone is free to share their input, but when it comes to certain things, there needs to be some reality checks. Some egos will get hurt, but the last thing we need is people spouting stuff out like it's gospel without any factual base. Hell, that's how wars have started

 

True!

IMO, early pre-production 2003 G35 AT Sedans tested by magazines were "ringers". Not an uncommon practice! That said, there are exceptional production engines out there. I've seen one at most every dyno day I've attended. We've published two articles --G35 Dyno Marathon (Winter 2005) & Desert Day Desert Day Dynoing (Summer 2005) that help support this observation.

Unlike many who profess that G35 mods don't work, my personal experience with my 03 doggie door AT Sedan indicate the right ones do... at least according to the dyno, G-Tech, street encounters, and dyno-butt evaluations. Stock my 03 doggie door AT Sedan made 208hp/206ft-lbs torque at the rear wheels (260 x .20 = 208) which is in line with the generally accepted 20% AT drive train loss. After modifications, the car has dynoed 262 HP and 261 lb-ft torque on a Dynopack (unfortunately pinging above 5k).
Here are the results.

I invite you to compare the above torque numbers with other N/A cars. Since this dyno I've made three additional mods. The car seems dyno-butt faster from 5k to 7k. Time and testing will tell.

Disclaimer: The above reflects my personal opinions.

 

I can't believe you're all arguing about this again.

Bottom line:

The 05 engine dynos higher than the previous year models.

The 05 cars are not that much faster if at all due to the increased weight.

 

DaveO-

Nice numbers!!!!


That brings up another question. How did the 05 gain all this weight? All I hear is speculation about how the car gained so much weight. According to Motor Trend, my DMV registration, and NADA, the curb weight of the 03 G35 sedan 5AT is ~3,370lbs. According to MT and Infiniti, the weight of the 05 G35 sedan 5AT is ~3,520lbs. How in the world does a car gain 150lbs in weight with no body changes or significant chassis changes? As defined by DOT, curb weight is "weight of a ground vehicle including fuel, lubricants, coolant, and on-vehicle materiel, excluding cargo and operating personnel."

From what I can see, the weight gaining parts on the 05 include:

1) Fractionally larger brakes. You're talking maybe 10lbs total from all four corners. Rotors are pretty dang heavy (~20-25lbs).
2) Optional 18 wheel/tires. I would have thought this would have been the most significant weight increasing item though Russ says the 18" combo weighs no more than his 04s 17" combo. On average, 18" tires weigh about 3lbs more than 17" tires of the same diameter.
3) Telescoping steering wheel. Maybe 10lbs.
4) Painted lower sills? 8 ounces

Seriously, what else is there? Some people like to think that the bumpers were somehow reinforced and that accounts for the weight, but if you've ever seen under the bumper cover of a later model car, you'd see that the bumpers themselves are often alumnium and foam. Off the car, they weigh 10-20lbs including the bumper to chassis frame. On the G, the bumpers are alumnium.

Could it be additional sound deadening material like many seem to think? If this was truely the case that the 05 had an additional 100lbs worth of sound deadening, why aren't 05 owners talking about how quiet the car is compared to the older models? BTW, an additional 100lbs of sound deadening is a crap load and I doubt you could cram it into the existing G35 interior panels and carpeting.

I think the 03/04 3,370lb curb weight was for the Base model G35 which didn't have any weight gaining options like 17" rims, moonroof, dual power seats, reclining rear seats, HIDs, and subwoofer. Those options right there are worth about 80-100lbs and would kick most 03/04s into the mid to high 3,400lb range. As far as I know, there is no more real "Base" model G35 for 05. Maybe Infiniti choose to select the curb weight of fairly optioned 05 as it's reference this go around?

 

Man DaveO your 03 dyno'd worse than my 03.5. We got 213/216 at the StrictlyZ/ SportZ Mag Exhaust shoot out. I have been told that someone got you the resutls so I hope they have been factored into all the stats you have.

 

I am not trying to be a trash talker, I hate being the punk kid who talks trash, but enough is enough. The 03 is not slow, but you are out to make it the best. If I bought a used 03 I am sure I would love it too, but I wouldn't go around saying it is under rated and the fastest G out there. I bought a 6MT to get the best performance out of this car, because as an undeniable fact, a stock 6MT can be driven faster in a 1/4 than a stock 5AT.

So if your G35 does indeed posess 280hp, then WOW, WOOOOOW, you know bro, putting all **** talking aside, I am damn impressed that your car has 280hp, I hope you sleep well tonight. The 03 is still not the fastest as someone already ran a 14.0 in a 05 6mt on 6mt.net.

So good day Mr. Super Fastest 280HP Ultimate 03 G35 Driver Dave Who Can't Let it Go That Infiniti Rated His Engine at 260HP.

 

those are your words, not mine

 

People have already gone 13.9s in their stock 03/04 6MT sedans. What's your point?
