I traded my Evo8 for a 04 4dr G35 a few weeks ago because of my family. I am very satisified with the G35s ride quality and it's performance, when compared to all other sports sedans. But I was wonder how to give it a little more umph, a little more power. I not stressing the suspension because I'm not trying to autocross or go around corner at 60mph with my baby in the back. So for NA cars, what is the best way to make more power? I know it sounds retarded to ask, but I never owned a NA car before. Please tell me what parts and what brand is the best. Thanks for the help.

And can you give me some brand of exhaust systems that is not rice cannon looking, and not much louder than stock, and looks pretty much stock?

 

i'd suggest you do a lot of searching, reading and research. to get started, i'd recommend a plenum spacer or MREV2. best bang for the buck mod out there currently. exhaust wise, for the sedan the stillen exhaust seems to be the most popular. looks good and it sounds pretty good in person too.

 

-Plenum Spacer
-Z-Tube
-Stillen or JWT Intake
-Exhaust (Borla is not as loud as the Stillen so you may want to consider that because you have kids that may be sleeping in the car, I have a 3 year-old)
-ECU reflash (Technosquare)

If you still want more N/A power
-Headers
-Cams
-High flow cats or test pipes


Good luck!

 

is this z-tube better then CAI???

 

The best way to make serious additional power on this car without going FI is to trade it in.

Seriously. The amount of $$ per horsepower gained is too expensive IMO.

Lots of things increase the SOTPM, but few, if any, translate into real, neck-snapping (or even neck-bending) power increases.

Ask for #s to substantiate the claims is all I'm saying.

 

highly recommend mrev2. Great product. This is the only mod to my car that i can actually feel a great difference from. Rpm's pull much faster past 5500.

 

Exhaust is a good way to go for more power, but you're going to hear it. The Stillen dual is MUCH louder than stock. Plan on replacing the resonators if you want to tone it down a bit - but you're still going to hear it. It does look comlpetely stock though. Most replacement exhaust systems will be louder. "With great power comes great noise" - that's why we love it .

 

This post hits the nail on the head. I've had many N/A and a couple of turbo cars that I've modified. You will be VERY dissapointed in both the Infiniti aftermarket, as well as general inability to do much with import N/A cars vs your turbo Evo.

While it's true that the fastest car I've owned was N/A (10 sec Camaro SS), I spent plenty of money to get it there. Fact is, I could have made it faster for the same money (FI or nitrous), but I wanted to stay N/A for safety purposes. The LS1 has lots of heads/cam packages that produce good power. The Infinit does not.

Of all the cars I've modded, the G is probably the most frustrating, because the only mods that make big power are not N/A and the aftermarket is quite weak. You are coming from the opposite end of the spectrum, as the Evo is easy to mod cheap and has huge aftermarket choices.

 

He is not asking for big power.
I agree that you are not going to get more than about 50hp with NA mods.

I disagree that the aftermarket following is weak for the G. Compared to some, yes but it is a sports sedan, not a camaro. They probably outsell the G sedan 20:1 here in the US and a higher percentage of the owners want to mod them. I have owned plenty of other import cars with much less available for them than the G. I guess I am just happy with the options I have.

Just my $0.02

 

Forced Induction = best bet

 

GeeWillikers is on point...our cars are tuned very well to begin with and that is why all of these NA mods don't do much. And the fact that these are Infiniti's...too much $$$/hp ratio.

 

Actually modding my g so far has been cheaper than my old maxima. I bought all my stuff used. I think some of the na power mods are good. K&N panel, plenum, spacer or MREV2. ECU timing advance tweak. After that the gains get pretty expensive.

 

Well, right now the G is way outselling the Camaro

When I say Infiniti, I'm really referring to the VQ motor, which has been hugely popular in Nissan and Infiniti vehicles since 1995. Given the number of cars sold with this motor, I am shocked by the lack of aftermarket support next to other cars. Hell, I had an SRT-4 which only had a few year run that the manufacturer themselves did mods for. I made that car very fast for less than $1500. My Volvo S60R sold many less cars than G's, but had some really good aftermarket choices (not many, but good). My current car, the Charger SRT8 has at least eight great exhaust choices to choose from, not including the one from Mopar themselves! This car is in it's first year!!

My co-worker has a Toyota, and he can go to a number of different places for aftermarket, or he can go with the manufacturer's performance parts (TRD). When I did a search for Nismo parts, you get a CAI and a couple other goofy choices. It's just different.

I'm not saying there is nothing to choose from with the G. What I'm saying it that its very limited compared to other cars. That's all.

 

first off congrats on the car. My neighbor has a Evo8 that is making 430 at the wheels and is certainly a sweet ride that can plant you in the back of your seat, but with one kid and a second on the way he is looking for something with some more room.

the posts above pretty much sum it up. G owners who want to mod, want some neck snapping power to go along with it, but unless you go FI or NO2 it's just not going to happen. So I suggest Z tube + K&N, which may give you about 1 extra pony, MREV2 or spacer gives you about 10 more (maybe) all of which you can get for less than $350. The real capital in the above 2 mods would be added induction noise which certainly makes you "feel" like you have more power under the hood. If you are looking for more expect to shell out some more serious dough for cats/test pipes, headers, exhaust, however by the time you do that she'll be so loud you'll want to go FI anyway.

 

the NA VQ35 is perfect. do get more power go FI

why do you think the new generation NA VQ, which is said to have 300+ hp, needed to be "80% redesigned"? it isnt that easy to squeeze NA power out of the VQ...it -wants- to be super/turbo charged
