Thats great except when you start adding mods the gains come at the expense of your low end. I rather have Infiniti Engineers tune the car than have someone else attempt it.

 

no brembos, but the 05 brakes with 12.6 rotors are almost on par with the brembos. Unless you're tracking you wouldnt notice anything, except for the not existent squeeks that the brembos exhibited.

 

Thats all nice to say and makes a good soundbite, but the truth of the matter is that the peak torque and peak HP don't matter. What matters is the area under the torque curve, and from everything I have read, the 05 has more area under the curve. True, the 04 has a higher PEAK torque, but the 05 has a broader curve, both at the low and high end, thus having more total area under the curve, and making it faster.

But, hey, if that extra 10 ft-lbs at peak make you feel better, more power to ya.

Anyone without a simple concept or understanding of physics would say HP is for bragging rights. Torque measured on the engine as work, which means a force applied over a given distance. power (hp) is the time work is done per a measured amount of time. if an engine has torque, it "works" but not necessarily in the amount of time you would like. When performance is added to the equation, its all about how fast you can do work...where the measure of horsepower comes into play.

I would honestly say a 7% increase in hp would result in a tick or two off the 1/4 mile time. If the '04 G is running 13.9 mile...I wouldn't be surprised if now it can run 13.8, 13.7

It is true driving around the streets shifting under 3000rpm with a '04 6mt would be a tad more enjoyable. But remember a QV engine can be easily revved past 3000 even on street driving, which is where the 20hp comes in handy. Need to overtake a civic at the light? Need to accelerate faster onto an on-ramp? give me the 20hp at the cost of 10 ft-pounds.

 

TQ win races? doesn't stop the NSX or a S2000 from winning Tsukba (sp) track races on best motoring.

 

Say what? Someone said they would prefer the Brembos over a V8? Are you carzy or something? I know those brakes are great but the 2005 brakes are not too shabby either. Give me the V8 G and I can paint my calipers yellow to look like the Brembos anyday...period!

 

i would still take the brembos over the revised interior and 300hp

 

Like the previous poster said. Anyone with any understanding in physics would know that HP is a function of torque. As in HP = TQ*RPM/5252.

S2000 gets by with little torque, because it has a flat torque curve, and a 9500+ RPM redline. Those japanese motoring videos showed that unless you dumped the clutch at 7000+RPM, the S2000 would net you mid 7 second 0-60s. Dump the clutch, and you can get sub 6 second runs.

 

This thread could be argued from all kinds of stand points and at the end of the day, it is still a G35 coupe! I think Infiniti did a good job on the inside of the 05 and many things they incorporated I would love to have in my pre 05. It is also commendable that they added 18hp, HP is always a good thing! Shame on Infiniti for removing the Brembo's. Sure the 05 brakes are going to be good and most don't track to feel the benefits of the Brembo's and those that do, probably don't do the necessary maintenance to make the brembo's really shine. BUT..........what the Brembo's do do IMO, is set apart the car from the rest of many sports coupes out there! How many with pre 05 6MT's will attest that you ALWAYS catch people peering inside your wheels checking out the brakes......I for one will! The add a trick factor that all enthusiasts drone for and usually have to spend thousands to get it. So performance aside, I am sure the 05 ROCKS and I really like alot they did with it! Congrats to all those that have 05's, it is a sweet car and you have 18HP more than all us pre 05'ers (stock that is)!

 

They both suck a$$...get a Neon better.
You'll get better gas mileage and less speeding tickets.

 

2003 verses 2005 6mt. Its been awhile but I had my old 03 6mt today to get it safety inspected (My ex-wife drives it now) It is still in perfect cond. I find that my new 05 6mt Shifts better and is much more docile driving around town. I think the low end hp is much smother and I do not remember driving around town if fifth gear as much as I can with the 05.
This I can say at 5500rpms hang on it will be 7000 rpms way to fast. The 03 started running out of steam around 6500rpms. I believe the 05 is much better balanced and by no means is it less torquey. 3rd gear in the 05 is were you feel its "*****" The only rattle I had was that cheap tire jack in its plastic carrier rattling around and the tow hook was not in its carrier. Easy fix" As for the ride the 05 will blow the 03 away in the twistys and this is where the power band comes in very nice. About the brakes?
The 05 seams to do there job nicely but I do not like using brakes to the point of over heating them. I have had a lot of cars and I still believe the engineers at Infinti are way smarter than me. I can say that the clutch and trans is a little noisy at warm up when you first start off but dam its cold up here. Think about where the drive train is in this car its very close to your ears and you can here everything. I just cringe when I have to start the car up and its 10 degrees out side. The BOSE system is a little weird but I have found you almost have to warm it up also. The other thing that is weird is all of the kids in there riced out cars want to race and that draws to much attention. My first car was a 1968 Datsun roadster
And that car was just a blast. Nissan has come a long way. Thats right Im in my Fortys.

 

roadracer, I completely agree with you on this one. Its a shame they removed the brembos for 05. Nevertheless, IMO I believe they more than made it up with the power, transmission, interior updates.

 

Has anyone actually seen an 05 dyno yet?

 

I can't (or rather don't want to) comment on the 04 vs. 05 debate. However, I am wondering if anyone has any more information about the variable exh cam timing that was added to the 05's. Was it the cam timing or the cams themselves that caused this hp/tq change between the years? Also, Nissan claims that they made some structual changes to the shortblock itself. Has anyone heard what specificially was altered? Did they have to do this to support the higher RPM powerband?

 

no rattles in my 6mt.
