I am still a Noob. Decided I am going to buy a G35x. Probably will be newer than an 2003, but if I find one with low mileage who knows.

I have been working the search button and this is what I learned, I think

2003.5

1) Is the same as a 2004.0
2) Went from mech. fan to elec. fan
3) Doggy door dropped
4) stripped base (cloth interior, non-HID) no longer made
5) ECU major update
6) Began with VIN # ?????????


2004.5

1) Same as 2005
2) TCU now in the tranny
3) Begin with VIN (Sedan) F* 4M600001 or (Coupe)E4FM700001

 

Im pretty sure there's no in between in the 05 06 models

 

06 bluetooth became available with premium package


And 04 is not the same as 05. They made the 05 redeisnged completley. 04 looks like an 03.

Aren't the brakes on the 06x larger also? dual piston calipers up front?

 

Yep. 05Xs still have the small brakes where as the 05 RWD has the bigger brakes. (Compared them to a local guys 03.5 and you definatly see a size difference)

 

06 G35x was the only AWD model to get the larger brakes out of the first gen coupe/sedan.

 

06 changes over the 05 were: upgraded brakes on the X, upgraded navigation interface (runs on the 7.x DVD instead of 6.x like the 03-05), and bluetooth.

 

Bluetooth is meh anyway. Don't kill yourself to find a car with it

 

03-04 = Nismo Body Kit / 05-06 = Front Lip. ( When it comes to OEM )

Figured I just add that in for the hell of it. lol

 

You get 18" sport wheels on the 05-06 sport models as well vs the 17" wheels on the 03-04.

 

It certainly will since the X didn't come out til 04. Sounds like 06 is the way to go (just for the brakes) if you can't afford a second gen (07+). Also, auto trannies got downshift rev-matching in 05, I believe.
