I have an 03 g35 coupe.
- 60k miles
- 100% stock
- 6mt,
- not a single rip in the leather.
- Brembo brakes,
- the paint is near perfect with some minor defects
- clean title
- 2 sets of keys
- zero rust

I just did the valve cover gaskets, coils and spark plugs, along side with oil and filter about 400 miles ago

It was granny owned for 95% of its life. It has all original owner manuals, the first aid kit, and some car of the year magazines. I’m interested in selling it but don’t know what it’s really worth. What do yall think?

Does anybody have any experience with these AliExpress digital dashboards? They're listed for G35 and g37 07-13. Now I'm not asking folks for advice on buying something from AliExpress. Has anyone seen someone use this? I found 2 seperate YouTube videos that didn't look sponsored of someone installing one, everything matched the Ad, easy plug and play install. And the guy went through all the menus in real time and it was actually really dope. One of the available Dashboard menus is the GTR one.

My question again has anybody seen these in the wild, or at least seen someone here on the sub install, or talk about one?

I just wanna be as informed as possible before dropping 900 on a product that will take a month to get here, and although I have faith in refunds from AliExpress I've got them before. But it's a big hassle and pain in the ass to do it.

Thanks y'all!!

Hey, was curious on the rarity / value of Caribbean blue slick top coupes. I don’t see many non-sunroof cars, let alone a 6spd Sport coupe. So I just wasn’t sure if they were worth any more than usual. Thanks !

TLDR - drove through big puddle, now car cranks but doesn’t fire and has a lot of codes.

Play-by-play of my issues below. Any help here is appreciated. Thanks!

1. Drove through massive puddle during heavy rain. Parked car for the night after arriving home.
   
2. Car started electrical buzzing noise from fuse box. I noticed once parked. (this has happened before and gone away on its own)
   
3. Try to start car following morning… car is completely dead. Like it has no battery in it at all.
   
4. Swap a different battery. Car now cranks perfectly but does not fire at all. I also notice some “weirdness” like wipers activating when key is inserted despite the wipers being set to “off”.
   
5. I scan the car for codes and see a lot of codes. See pics. These codes appear to generally indicate that the ECM is not communicating properly.

I got a P0420 code and based on live data I’m pretty sure it’s the catalytic converter. I just got the car smogged 3 days before this code popped up.
Can I just drive with this until I’m forced to address it for future smog or will it lead to further issues?

Hi has anyone ran these Tomei Procams 258* 10.20mm on their Vq35de non revup? Also wondering if they are worth it and how much does the exhaust tone change.

I've been trying to figure out where to mount gauge pods in the center console region, and I don't like the infotainment screen/sunglass's cubby location, its quite busy in my opinion. So I've come up with putting it on top of the Bezel. I'd really like to hear your guy's thoughts on this project.

Edit 7/23/26: the file has been released on Cults3D I have pictures of it printed and fitted into my dash on there if anyone is curious as to how it looks and fits in the car.

Im putting a new engine in my g35 rev up and would like to put some mods on the engine before putting it in. I have no problem with tearing into the engine just a little bit to do it, but I've heard that you really can't get much more HP out of these engines without forced induction. So I'm just wandering what you Guys know.

Just bought a 2004 G35 coupe with 150k ish miles on it. But this whole time I’ve been battling those codes. New throttle body and gas pedal assembly put in to see if the codes would do away and they did not. I’m not too sure what I’m doing. I have a very weird bogging idle and the cars fell flat on its butt and shut off twice after idling.

The gas pedal assembly and the throttle body are putting out weird volts so both were replaced and even with that the weird volts never went away. Fully pressed gas pedal the accelerator pedal sensors show 4.21 and 4.12 ish volts which isn’t right lol. And throttle body sensors both sit around 0.71 and 0.70 which is also so wrong.

Any ideas before I take it to a shop and have them look over my wiring harness? Thank you :)

it's so cool to see these out there still!

My driver speaker has never worked since I got the car going to try and fix that and add this bose adapter to hopefully get a better output

I dropped my cam caps and they became scrambled. What can I do? There are no identifying marks. Can I send it, or will it just destroy the engine?

Thanks.

I installed subs in my 2007 g35x with the Bose package. I am using the lc2i LOC. I initially tried to tap into my factory sub harness speaker wires without success. I am going to tap into the factory amp speaker wires but I am getting conflicting information on the color or the positive and negative speaker wires. I have attached a picture of the harness for reference.

Been hearing a tic for about 1-2 months now, at first tried Mobil 1 5w-40, now on a run of VAL restore and protect 5w-30, lmk what yall think

This has been in my family since the early 2000s and now, as a 30 yr-old father with a toddler and new baby on the way, with work that involves inventory hauls for a food service business, I’m in the market for a daily-use truck.

For a 2005 vehicle, it has its normal aging.

I could keep it in the family circle but I’m not looking to take up more space at home. It’s a fun car. Sucks that it built a rough reputation here in the states but it is such a fun car to drive.

Do you know anyone that may be interested in something like this?

I have this 350z single exit for my g35 sedan and I want it to burble a little bit with it on is there anymore exhaust mods I should get like a cherry bomb or something to get it to burble/pop?

clicking noise coming from rear driver side wheel area, thanks in advance. video was car at 5 mph

Hit the interstate up early ... nobody lurking except 1 wrx (and a lambo that paid me no mind 🙄🙃) but them beeps n thumbs up / showing love on a cruise is whats it all about

My 07 g35x vq35hr got some codes: p0300, p1148, p2a00, p0455, p0442. It only misfired on a cold start then after the idles dropped it was fine. It’s got a slight jerk under light acceleration and stops when I either accelerate harder or take my foot off the gas. I just did my plenum gasket and p0442 and p0455 came back after about 30 miles of driving.
