Most of that info looks accurate.

FOR 2003-2006 model years

6MT = all have 3.5 FD from factory.

X = 3.5 FD from factory for all years

5AT Sedans = 3.3 FD from factory

5AT Coupes = 3.3 FD (2003-2004), 3.5 FD (2005-2006)

(I'm not 100% certain on 2005-2006 5AT coupes, but this is my findings/belief based off local friends vehicles)

 

My 2005 5AT coupe had the 3.3 FD, no VLSD. Also did not have a sports package.

 

The AT had taller gears than the MT. Not until 5th did the mt gears get as tall as the AT. So we get screwed twice!

 

Are you sure about this???? My 6MT sedan runs at 2800 RPM @ 80mph....

 

^That's because 6th in the MT is a taller gear than 5th in the AT. That makes up for the shorter gear in the rear-end.

 

Yes.


The only part I'm not sure about is whether or not 5AT coupes have 3.5 FD. My friends 2006 runs at 3200-3250 rpms (pretty sure he's got 3.5) and he is bone stock.

 

Confirmed last weekend that my CC works up to 91 MPH.

 

Good Lord!!!!! Call the presses!!!! Marcus went zooooom!!!!!!!!!!

What got into you to go past the speed limit????

 

Lol

 

3.7 fd @80mph 3200-3250rpm

 

My G35 is back on the road

2003 5AT Coupe (cdn model) with 3.7

2500 @ 60 mph

3200 @ 80 mph

Note: My CC work at ~60 mph but at ~70 mph or more I get the blinking light and no go.

 

70 MPH huh? hrmm

Maybe your staggered wheel setup changes things from my sedan.

3.69 gears are about 10% increase over stock. Stock limit is 90 MPH, and at 10% over stock it seems like it should work up to 81.8 MPH for the variance if my calculations were correct.

How do you like the 3.7s?

 

6mt 4.08 at 60mph 2450 didnt get to 80 yet...

 

^^^ without knowing what gear you were in that doesn't really tell anyone anything... is that in 6th gear?

 

ding ding ding! we have a winner! yes sixth gear
