Official Modification/Information Thread:

I notice a lot of people asking “How can I make my G faster” or “How can I make my G handle better” and the most popular “What mod should I get”. Well this is the thread that I can hopefully answer all of your questions.

Models:
- 03 - http://www.edmunds.com/used/2003/inf...67/prices.html
- 04 - http://www.infinitihelp.com/Infiniti...escription.htm
- 05 – http://www.infinitihelp.com/Infiniti...escription.htm
- 06 - http://www.infinitihelp.com/Infiniti...escription.htm
- 07 – http://www.infinitihelp.com/Infiniti...escription.htm

Known Problems:
Infiniti’s are known for there rattles and various little problems, nothing major but those little annoyances that keep coming back. Most people can deal with them but they should not keep you from buying the car. On some 6MT the clutch pedal can be a bit annoying as in sticking or sometimes the clutch starts to slip (http://g35driver.com/forums/showthread.php?t=161770). Does not happen to every 6MT but to some. Also I know Infiniti has a weak point on windows. Sometimes the automatic windows act up. But all these problems can be fixed under warranty. On 05 and 06 there were some engines consuming oil pretty rapidly(http://g35driver.com/forums/showthread.php?t=188688). But can be fixed through Warranty.

Infiniti Dealer:
For the most part, Infiniti is a great dealership. They usually get right on the problem and hopefully fix it the first time (Atleast mine does, does not mean your's will). Although I have heard of some weak dealership service. If your car is out of warranty, Infiniti will empty your pockets with labor cost. In translation, VERY EXPENSIVE. BUT, if you have the money I would highly recommend taking it to the Infiniti dealership. Or find a local shop that does quality work. Great dealership here: http://www.riversideinfiniti.com/j/i...acyPolicy.html

PM me with other stores, I just do not know any due to not buying any parts.

Engine Modifications:
- Twin Turbo – The best option but one of the most expensive. It can increase your Hp by 40%. Plus not to mention if you have other modifications you could get up into the
500 – 700HP range. The cost is from $5500 to $8000 not including the labor. But for a quality install it will run you about $8000 to $10000 total. Stock motor with forced induction . . . how badly did you push it?
which way would you go..if you had
- Built Short Block – You can buy one from Forged Performance, Ballistic Motorsports, and maybe GTM.
- Motordyne is the best bang for your buck. The 5/16 spacer can give you a total of around 11 HP and the ½ spacer can give you around 15 HP. revup or non-revup / plenum spacer
2005 6MT Coupes.. +18wHP +22/29wTQ!? - A Thanks To Tony, Motordyne Engineering
- Intake/Exhaust – Do not base your ultimate decision on HP increase with intake. You will not feel it but you may see a 1-4 HP increase on the dyno but that is NOT a given. The most popular is the Stillen CAI with a z-tube and also the JWT popcharger which I personally would not recommend due to the heat shield. Just save up the extra cash and go with the stillen. Exhaust is mostly for sound but you can see some increase (sometimes 10-15 HP. I would recommend Fast Intentions if you go Forced Induction. The Greddy is also nice. I got my Fast Intentions Intimidator exhaust today.

Suspension:
- Tein Basic – One of the best bang for your buck coilover systems. Spring rates 504/504 Stiffer then oem by F+61% R+43%
- Tein Flex – A great mod for all of you who want great handling with little roll going around corners. However it is just a tad stiffer than stock. Spring rates 672/672
Stiffer then oem by F+114% R+98
- Tein Comfort Sport – Great for every day drivers who want a great riding car but wants to race those corners. However this is more geared to comfort than sport. I would highly recommend them for a daily driver. Spring rates 392/392 Stiffer then oem by F+25% R15%
- Tein S Techs – Great for dropping your car low. (fronts are progressive, rears are linear) Spring rates in LBS 358/274 (final rates only, softer intial front progressive rate unknown)
- Tein H Techs – Good for a moderate drop. (fronts are progressive, rears are linear)
Spring rates in lbs 324/260 (final rates only, softer intial front progressive rate unknown)
G35/350Z aftermarket coilover, springs and shocks spec's w/updates
Sway Bar Summary!

With these you might need a Camber set to help with tire wear. Also known as feathering where the inside of the tires wears down fast due to the stress on the inside part.

Tires/wheels:
I have no idea sorry. Someone PM with good informative threads so I can update this.
Some companies include:
• Volk
• Maya
• HRE
• Falken
• Pirelli
• Toyo

6MT Clarifications:
How to correctly drive an MT.

If I am missing anything just let me know and I will be sure to add it in. Just PM me so you do not clog the thread. I will also update this thread when I have time.

**Please note that the search is your friend. It is located at the top right of the forum/thread page**

Thank You!

06 -07 – More for luxury due to NOT having brembo brakes but have a new design interior, tail/headlights, and a more giving suspension. 306 Horse Power.

The new interior came in 05. No G35 came with 306 HP. I wouldn't say having a new interior, no BBK, new heads/tails makes the car any less sporty than the previous years...

You fail to mention what makes them so great. I've seen GTM's work first hand and it's fantastic, but I can't speak for the other two. I think you need to justify your opinion here. Just a suggestion.

There are plenty of Sponsors on here that can get us the parts we need. Most have a website as well.

But again go with what you like best as far as sound wise.

Plenty of people have seen gains with after market exhausts, and others have not. That's not justification, IMO, to say that exhausts are just for sound. You claim intakes may make 1-4hp? An exhaust is likely to do more than an intake will. And why do you recommend the FI exhaust for f/i applications? It may be good for some f/i applications, but to recommend it to all that go f/i isn't exactly the smartest thing to do.

Why only Tein products? There are plenty of other great brands for suspension out there. And why only mention products used for lowering? What about sway/strut/gt-spec bars?

PS - i hate PMing.

I believe your post is considered clutter, yet you still did it!

Besides, so long as he edits the first two posts then there is no cluttering to be done. It's not like people will have to search the entire thread and look though all this clutter as long as he updates the first two posts.

I think he was referring to the Sedan with regards to the 306hp rating, however his year to year updates are all over the place and obnoxiously unorganized. Some of the changes listed refer to the Coupe, others to the Sedan and some of the information he listed is just plain wrong like stating that '05 Gs had Brembos.

Good point. Seeing how this is posted in the Coupe forum I completely ruled that out and was baffled when he even mentioned Sedans. If this "Official" thread is going to talk about both Coupes and Sedans, then I'd think he would've posted in The G-spot.

06's were still rated at 280 for 5AT and 298 for 6MT.

The new SAE ratings affected 07's numbers.

What? No. Your 5AT is rated at 275 HP, but it's the same as all the other 5AT's.

Most dealers FTL. Very few people advocate going to the dealership for service. Most Infiniti dealers are actually notorious for their bad service. That isn't to say that there aren't some good ones, however. If possible, it is highly recommended to get your work done elsewhere when possible.

Fixed

Thanks! Im still working on some things as we speak. Also I only know of Tein. That is why I said if anyone else has any other info PM me so I can add it. I am just trying to limit the What do I do next threads or what is better as you see about 5 of them on the first page of 03-06 Coupes. I just want to do a general thread. They can Use the search button for detailed info. Also I did not list what is great about the shops because I figured I did not have to. It would be a waste of time because there is so much of it.
Thanks!

:

Dealerships are good and bad what you don't hear is the stories or the whole truth on service sometimes.

As far as GTM I reserve comments that will get my post deleted. Are they what they say they are? I say do some homework. I have heard some Horror stories that seem to mirror VRT. Again they are not from my first hand experience.

Man, My dealerships are amazing. They fix the problem fast with a quality job. Lets be real, no shop is ever going to be perfect. They are all going to make mistakes. It matters how they fix their mistakes.
Thanks!
