is that the diff just to the left of the module?

 

Yeah.

Also, there's a light in the dash. If you have RAS, it will illuminate for a second when you start the car. If you don't have it, it just stays dim.

 

Hey everyone, winter is coming and I am shopping for a VLSD preferably a 3.5 or 3.7 gear set. I'm finding a lot of 3.3's out there and I was wondering if there was a way to tell what gear set the differential is? OH and also if it is actually a VLSD or just an open diff?

Thanks in advance for any information.

 

The difference between the two is here: https://g35driver.com/forums/brakes-...ferential.html. For the gearing, its how many rotations the flange makes for one complete rotation of the half shafts. The flange may turn exactly three and a half times(3.5), a little less (3.3), or a little more (3.7+). I'm not sure about the actual markings on the diff though.

 

How much does a new engine for a 2004 G35 cost?

 

Need more info

Short block
longblock
complete engine


Remanufactured? or used?



I see used, complete engines on Ebay from salvage yards from $750-1500 or so and remanufactured long blocks for around $2500-3000

 

I have a rubbing problem. My car's front fender height is at 24.5". I'm on coupe 18s with the stock 225/45 tires. Before getting my car aligned, the tire would rub on the fender some when turning, but not too much. I told the alignment shop to add as much negative camber as needed in order to stop the rubbing of the tire on the fender. Upon picking up my car, the alignment shop told me that adding negative camber would bring the tire closer to the control arm, and that it would rub, so they added some positive camber to the front wheels (it was aligned at -2.5 left and -2.3 right). However, after getting my car back, I rub all the time when making a moderately sharp turn. Is there not a level of negative camber where it would not rub anywhere?

 

Are stock height? There's no reason it should be rubbing if you aren't lowered. Hell I was even lowered an inch with those same numbers (-2.3 on both front wheels) and wasn't rubbing and I'm on stock 18s with the 225 fronts.

 

Nope, stock fender height is 28". I'm lowered about 3.5" in the front

 

Goddamn. At that low, I couldn't even try to answer your question. There's probably a lot more going on than just camber. Rub on, man.

 

Fender pull time

 

Thanks for the info! I was actually shopping for one online so I wouldn't have been able to turn the flange and was wondering how to be able to tell by looking at pictures. Sorry I didn't clarify that. My biggest fear was getting ripped off and buying an open diff 3.3 gear set.

Anyway I managed to find a 3.5 VLSD from a 350z at a local scrap yard for $250!

With some additional research I learned that the numbers on the differential "38311" means 38 tooth ring gear and 11 tooth pinion for a 3.46:1 ratio.

I finally got it installed and WOW the difference is incredible, I feel like it's what my car has been missing this entire time.



I also learned that my buddy with an '06 G35x also has a 3.5 gear set in his diff (stock) which explains why his rpms are always higher than mine travelling at the same speed. Also explains why he's able to keep up when we do pulls even though he has the added weight of the 4WD system.

On a side note, does anyone know what this is?






There's 2 of them and they fell off from under the car in the heat of the moment of dropping the old diff. Any thoughts?

 

hey guys i have a 2005 g35 coupe and today i was driving home from about 5 miles away and i saw smoke coming from under my hood. i checked my temperature gauge and saw it was extremely overheated i pulled over and shut off my car. i opened my hood and saw that my coolant reservoir had completely emptied itself and there was coolant all over my grill, radiator, and all around my reservoir. i filled it back up and made it home.. my tempature went back up steadily and when i got home it was overheated, i checked the reservoir and it was completely full..

i got my car tuned at uprev yesterday so idk if that could have anything to do with it.. any help would be extremely appreciated i have no idea what to look for

 

Could be a failed water pump?
Have you checked your belts?

Telcoman

 

The water pump on the G is not belt driven
