G37 Install help
The Infiniti G37 was released in mid-late 2007 in coupe format. I purchased my coupe in early 2008 as a replacement daily driver. From a personal perspective I have been involved with the Nissan Community since the purchase of my 2002 Nissan Maxima SE and can be found on numerous sites. Primarily, I may be found on NICOclub where I am an Administrator and web designer. If you have any desire to be part of the largest Nissan/Infiniti community, or need help and information please visit, they are a great bunch of people.
Since the purchase of the vehicle I have slowly upgraded and modified it from both a performance and handling perspective. For the first two years the vehicle
remained virtually stock with only exterior modifications. This changed in 2010 when a new online supplier of performance parts, Tunerzstore.com, hit the internet. I've known the owner of Tunerzstore since entering the scene
in 2002 with NICOclub and can't recommend enough people to utilize him for their parts needs as the guy is
above board and highly trustworthy. Am I biased? Possibly, but when you are involved in the import community you see what other vendors do and this guy is at the top.
Regardless, the vehicle became a product test bed for Tunerzstore and also a featured project vehicle for
InfinitiG37.com. A brief overview of upgrades is below and it should be noted that I have not received
a single SES or error code from any of the parts installed. Cursory mpg testing puts me around 26.5mpg @ 80mph with the current modifications.
Latest updates and Modifications:
05.04.13Brake upgrade. Time for the brakes to get some love besides a pad upgrade I performed 18 months ago. Brake fluid needed replacing anyway and rotors were to a point they needed turning again. Installed were new StopTech slotted rotors, Stainless Steel brake lines, and the fluid was replaced with ATE Super Blue Racing. All parts sourced from Tunerzstore. I had ordered a set of hawk pads but the Project mu front and Hawk rear pads that were on the vehicle still looked mint.
06.01.12Rim and suspension upgrades. I'm now running Forgestar F14 20" rims (20x9.5 and 20x10.5) with ContiExtreme DWS tires (255-35-20 and 285-30-20). Front Eibach A-Arms and rear Eibach lower control arms have been installed to allow for appropriate alignment. Rims are such a personal choice and it took me forever to find not only a good deal but something to my liking. The only negative aspect to these rims is they take a bit of time to detail and clean.
07.01.11Tein H-Tech springs are gone. These were G35 models as nothing was readily available for the G37 at the time and they are simply too soft. BC Racing coilovers have now been installed and adjusted. Due to being a bit stiff the rear springs were changed from 10k to 8k which helped but has limited the adjustments for height. I have a love-hate relationship with this suspension. It's made well and installation is a breeze. They handle great! For a daily driver they are simply too stiff at times and I have them as soft as they can go. Overall the vehicle has been dropped over 2" front and 1.5" in the rear so that has a lot to do with it as I've limited suspension travel, thus, not really the fault of the coilovers themselves. To compare them with the Tein springs is like night and day. The Tein springs were actually softer than the factory springs so the ride was ultra-comfortable but had less handling aspects. The drop was even more than I am currently running with the coilovers so without camber kits you will be replacing tires often. Soft + the drop meant I was scrubbing going over speed bumps and I hit the crossmember a couple of times. Tein's had to GO!
After a year of sitting around the Invidia High Flow catalytic converters were finally installed. The car is slightly louder and you can hear some additional rasp. "Butt-dyno" says more power.
I have upgraded the Front and Rear sway bars with new Hotchkis adjustable units. With the rear on the softest setting you can still notice less body roll while cornering.
07.01.10Tein H-Tech springs were installed on the vehicle which has resulted in a 2" drop and what seems a softer ride. Since that time the tires have been swapped out for Hankook Ventus V12 245-35-19/275-35-19's.
R2C intake system has been installed. Great sound with these things when approaching redline and they seem to have helped with breathing. I love not having to oil them and they do stay nice and dry in the engine compartment.
I have installed a TBW Lower Engine Cover. The factory lower cover is plastic, scrubs easily when lowered, and can flop around. For oil changes you have to partially remove it which means the plastic mounting tabs don't last that long. This cover is laser cut metal, powdercoated, and has a door that allows access to the oil filter by removing a single screw. The local Infiniti dealership loves this when it comes to maintenance.
05.18.10GTspec Strut Tower Brace Installed. Very nice product but difficult to really perceive a major difference. Vehicle seems to "turn in" crisper for cornering but without electronics to measure it could be me hoping it does something more. Regardless it will help stiffen up the front towers.
04.11.10I have started the push to upgrade the performance of the G37 coupe. Over the last couple of weeks I have installed a set of K&N drop-in panels, upgraded the tune using a Cobb AccessPort, and have installed a Invidia Gemini cat back system. The Invidia exhaust is a very nice stainless system and installation was quite easy. From the rear it looks similar to the factory single-muffler system but in fact it is a dual muffler design. The note is relatively deep and not buzzy. There is relatively no drone at highway speeds. The Cobb tuner simply connects to the OBDII port and can be used to flash ECU updates to the car. It includes pre-programmed tunes for various levels of modifications, allows you to create your own tunes as needed, and allows for logging and monitoring of live data. Unfortunately Cobb has since chosen to NOT continue support of non-boosted vehicles so the Cobb AP is no longer available for the G37. If you are interested in a tuner I suggest looking at UpRev.
Stock Track Time:11.08.08, Took the G out to the drag strip for the first time. I was hoping for low 14's but was happy to settle for a 13.835 @ 101.89. Not bad for a stock automatic. I should have been able to cut some time off with a good launch but traction was an issue off the line. I have not been to a track with the vehicle modified.

After years of driving my 2002 Nissan Maxima, it was time to upgrade. For years I had stated I wanted a Infiniti G35 coupe and I guess I waited long enough to have this next-generation come out right around the time I was getting serious into purchasing one. In June of 2008 I took the plunge and picked up a new G37 Sport Coupe.
While this is primarily my work car, my SO put her foot down on a Sport 6mt model (she can't drive a manual) so I had to settle for a G37 Journey which is the automatic version. The color is Ivory Pearl which I found out later is a 1-year color and only offered in 2008. The car also has the Premium Package and the Sport Package.
Never being one to let things stay stock for very long I actually had a jump on this one as I ordered an aftermarket rear spoiler when I purchased the car. The spoiler was added to the car a couple of weeks after purchase. I have also tinted the windows (35% front / 20% rear), upgraded the factory HID's to 6000k, upgraded the stock foglights with a 6000k HID kit and I have replaced the headlight running light with a LED.
All in All I give it a thumbs up. I love it and that's what counts.
