70,800+ 06 coupe.

 

stuff that went bad due to hardware failure:

exploded 4 transmissions changed O2 sensors, crankshaft sensor, camshaft sensors, a/c fan motor, at 220k somehow the crank became loose and managed to FLY OUT of place .... motor mounts, I packed the transmission mount with McMaster .60A urethane.

Reasons for failures:

Transmissions: Overheating, lack of proper cooling due to intense driving.
o2 sensors = motor mounts failed, caused Catalytics to fail thus causing chunks of **** to damage them.
sensors = wear n tear
a/c fan motor = wear n tear
Crank = best GUESS is the oil i was using was too thick (15-50 Valvoline VR1) causing oil pressure problems I haven't ripped the engine apart to know the facts so I am speculating.

Fixes:
Transmission(s) = Installed Transmission Cooler (somewhat large 8x10x1/2inch) This transmission has survived through countless track days, and 110k+ miles with no signs of foreseeable failures. Other transmissions have failed nearing 20k miles.

The rest of the fixes are just self explanatory.

I replaced the engine with a 2006... The differences are simply sensors... you have to use your 2003 sensors and engine wiring harness and it's plug and play.


So far I am up to 260,591 Miles. I think at this pace I should be up to 500k by 2015

 

04 twilight blue 126k
04 black 83k no problems with either car

155k miles 2004 black g35 sedan

 

157K on my 2003 Ivory Pearl sedan

 

2005 G35x w/103k miles

 

2004 G35x and 101k miles on her. No problems with this thing outside of regular maintenance

 

2004 Obsidian Black 6M/T Sedan 137,426 and going

I had timing issues, which was fixed
Still have oil burning

Need to:
- change valve cover
- replace wires & plugs
- upgrade clutch & flywheel
- fix or change mid-pipe(leak)
- change lower control arm bushings

 

2004 G35 Sedan 114K miles.
some quirky engine problems, body still in good shape, no rust.
interior showing some wear on the leather but still in good shape. no rattles or looseness.
Need my 120K maintenance soon.

 

Dang, some low mileage G's on here. I just rolled over 77K. I've put more miles on mine in the last 6 months than I did in the previous year. Moving to a big city isn't all it's cracked up to be.

 

 

06 g35x currently at 66k

 

Just rolled 90,000 KM on my 2005 lakeshore slate coupe.
