Bought a new G35coupe today... need help with mods.
Hi All,
I'm a brand-spankin' new G35 Coupe owner today!
Ivory Pearl White, 6 speed manual transmission, tan interior...
Wow! This car handles just as well, if not better than my 2002 Corvette C5!!!
As soon as I got home tonight, I ordered $110 bucks worth of Zaino Products... works great on the Vette, should work equally well on the Infiniti.
Anyway, I need some help with mods... this car is absolutely gorgeous as is stock... with the tan interior, I'm going to tint the rear windows and side widows with the brown/amber tint like on some sunglasses...
That's easy stuff... I know absolutely nothing about Japanese cars... but even with 298hp, surely there's got to be some relatively inexpensive mods for cold air, exhaust, tuning the computer?
Can anyone please give me some advice on where to start... On my Corvette, I switched out the OEM gears for 3.42 gears and had a torque converter installed... also cut a hole in the shroud behind the airfilter and installed a Vortex cold air box that uses a K&N air filter...
For the G35, I'm not wanting to do anything mechanical to mod it out... I would however like to improve airflow and possibly even use somesort of programmer to tweak the computer settings...
Are such mods feasible for the G35?
Thanks,
Mark

For more airflow you should go with a JWT pop charger...best bang for the buck. As far as tweaking the ECU you have to ship you ECU to Technosquare and they can reprogram it. I would not get the ECU flashed unless you get a plenum/spacer, CAI, test pipes, and exhaust. If you get all these mods then you need the re-flash. With just one mod the reflash will not be that noticable as if you redo all the breathing mods.
Congrats bro on the ride. As for mods, you can go crazy with this car. I would suggest you drive it for a while stock until you get used to it. Get to know it better if you never owned a Japanese car.
Definitely coming from a Vet the first thing I'm sure you noticed was the exhaust and the torque.
Performance
1. Ztube + KN filter
2. Cold air intake - there are a few you can choose from
3. Exhaust - you get better sound and HP. Check out the HKS system...it is my favorite and it sounds really nice
4. Lowering Kit - I like the EIBACH PRO KIT but you will find the TEIN is quite popular as well.
5. Wheels - get a nice set with good rubber on them.
I would start with these and believe me there are more than a handful of options for all of them.
With the first three you should gain approximately 30 - 40HP, and the wheels and lowering kit will improve your handling and help the car keep up with additional HP. It all depends on what you're looking for.
Check out some of the sponsors of this site. They can give you some good info.
Good luck.

This is dumbest comment and I have a black coupe. Maybe if he would have bought a pink g, I would agree with you. At least white does not show every scratch and ALL THE SWIRL MARKS.

Putting in the z-tube and JWT pop charger on the intake side is cheap, easy to do, and generally perceived as a desireable, and easy to reverse improvement. You can go to a larger flow plenum as well, but that is going to cost a few more bucks. Unless you go FI, that is about it on the inhale side.
Reprogramming the ecu and tweaking your engine management is available, to raise the rev limiter, modify the maps, etc. It is also easy, but you don't want to do that until you have finished all of the inhale and exhaust stuff and specify exactly to Technosquare what you have done so they properly configure the reprogram to what you have put on your car.
On the exhaust side the catback exhaust replacement is another popular mod. You can drop quite a few pounds in weight and get hp gains. You can do high flow cats as well. (I would stay away from the Random Technology offering at this time; mine and many others have disintegrated their elements within 7,500 miles, so they need to get that definitively under control before you spend your hard earned dollars...bear in mind it worked great...for as long as it worked). You might check into the Crawford option there.
Headers are problematic in the net gain to hp they give once you have done the cats and catback, (they give more gain if you have not done them, obviously, but the additive gains all have a diminishing rate of returns as you pile them on top of others)and they are an installation pain in the neck. They do give a very nifty growl though, and that is an auditory temptation that is hard to resist. Especially when you catch the reverb under acceleration off a k-rail or in a tunnel.....very satisfying !
With a combination of those features you might get 30hp or close to it. Not sure about 40, but as a return for your dollar spent, it is in a very nice reward range.
Real performance returns are in the handling department, since this car truly comes with a decent amount of power straight off the showroom floor. Nothing like your prior corvette, since this car is heavier and is a four seater.
But if you like the handling now, it can be awesomely improved with some carefully considered steps. Always it involves tradeoffs in comfort and noise etc. But for big returns consider going to stiffer sway bars, lighter forged wheels and bigger treadwidths, and coilovers. You do not have to go crazy with the budget either. A nice set of coilovers, dropping the car an inch, and stiffening up the sways will not cost much at all. Lightweight wheels are expensive, so you might want to wait on that a bit. If you are going to really want to push for truly competitive results, a big brake kit at least for the fronts is going to be in your future.
And then you will be thinking of a lightweight flywheel and clutch, and a limited slip differential. These plus the brakes mentioned above are getting you more into the "bad boy" world of performance and really are not necessary unless you have lots of excess cash and it makes you happy to have the capability even though you rarely get to use it....or you take the car out on track days for a few hours of zippy laps.
Have fun.

In your opinion, are the headers worth it after the catback alone? I was reading the installation procedure and it really seems like a royal PITA for a minimal gain.
if u dont wanna go crazy just get a z-tube and a jwt pop charger, cheap, easy to install and sounds great
