I am looking at the 2008 G35 sedan brochure, it states that the G35 sport package "includes all g35sport mt standard equipment, excludes 6 speed manual transmission, solid magnesium paddle shifters on steering column, foot operated parking break, available on G35 Journey."

The G35 sport 6MT includes VLSD and larger brakes and "larger front brakes" plus other stuff.

The mileage is stated to be 17 city and 24 highway for the auto and 17 city and 25 highway for the 6mt. The G37 looks to be 1 MPG better for both city and highway. Not bad since it includes additional horsepower and pushes more weight on approximately 5% less gas. The new valve technology on the G37 must be providing some real benefit. I am very disappointed that they have not included the valve technology on the 2008 G35 sedan.


The 2008 G35 Journey weighs = 3508.
G35x awd = 3704
g35 sport 6mt = 3532

 

That's the regular Sport Package, not the Sport Package AWD. The question concerned the contents of the latter.

 

Any definitive word on when and if a G37 sedan will arrive?

 

None I've seen anywhere. Just rumors. I have read that the engine bay in the sedan is too narrow for the 3.7. But, if true, they could probably engineer a solution for this. Problem is, that takes money.

 

Illogical - the exterior dimensions are the same - the engine was stroked.

A Stroker kit is an aftermarket assembly that increases the displacement of a Reciprocating engine by increasing the travel of the piston (piston moves further up and/or down in the cylinder). This is done by using a different crankshaft where the crank pin is moved further away from the center of the axis of rotation of the crankshaft. While this increases displacement and torque it can potentially lower the limit to which the motor can rev safely compared to the stock configuration.

 

Has anybody test driven an '08 6MT? Wasn't there supposed to be some minor tweaks for the 6MT? -vibration, noise, clutch engagement possibly???

 

As per infinitis web-site

G35X Sport Pkg. includes
-VLSD
-Paddle Shifters
-18" Alloys with Summer Tires
-Larger brakes
-Unique Front Fascia and Side Sills
-Spot Seats
-Unique Steering wheel stitching
-Aluminum Pedals

Found this on the "Build your Own Section"

It doesn't mention the sport tuned suspension.

Wow a loaded X goes for $42,5

Infiniti finally changed the G35 info on the website from 2007 to 2008.

 

I have driven the g37 6mt and the vibration, noise, and clutch engagement were all excellent. I have not driven the 2008 6mt sedan but the dealer says they have made the same improvements in the sedan. I will have to wait till one comes in to see for sure.

 

Yes, all they did to make the 3.5 into the 3.7 was throw in a different crank

At some point, the height of the block must be increased in order to fit a longer throw crank. I don't know if the 3.5 was at this point, but it could have been.

And I was just relating what I read, I think from someone here who'd talked to someone who worked for Nissan corporate. True? I haven't a clue.

 

This list, though on the site, contains ERRORS. Otherwise the price would be the same RWD and AWD. Instead, it's $550 lower on the x.

Here's the list on the Infiniti site, under the G options info:

Sport Package AWD

- Solid-magnesium paddle shifters mounted on steering column
- Split 7-spoke 18-inch aluminum-alloy wheels with V-rated all-season performance tires
- Unique front fascia and side sills
- Front sport seats with thigh extension and driver’s power torso and thigh support
- Unique sport steering wheel stitching
- Aluminum pedals

And here's the list for the RWD Journey's Sport Package:

Sport Package

- Viscous Limited-Slip rear Differential (VLSD)
- Solid-magnesium paddle shifters mounted on steering column
- Split 7-spoke 18-inch aluminum-alloy wheels with W-rated summer performance tires
- Larger brakes
- Unique front fascia and side sills
- Front sport seats with thigh extension and driver’s power torso and thigh support
- Unique sport steering wheel stitching
- Aluminum pedals

So, the AWD Sport Package appears to delete:
--VLSD
--staggered W-rated summer tires; instead gets V-rated all-seasons
--performance brakes

Looks like about $550 worth of stuff. This is what my site's been listing for the package.

Sport suspension is a question mark. It's not in either list, but is know to be in the RWD package.

 

Does anyone off hand know how much room is really needed? Say you increase the stroke by 10mm, then you only need a mere 5mm on top the cylinders. Is that enough to increase by 0.2 liters?

 

It's more complicated than that. They might have altered other aspects of the engine design. You need the actual external dimensions of the engines.

 

Yah I know, I just wanted to find out how much more engine block room is needed. I did the math and it needs 4.7MM more stroke which puts the heads 2.35mm farther out. Unless the heads are considerably different, how much more room do they really need?

 

I would speculate that the additional space is needed for ,vvel, variable valve event and lift system. Much more clap trap is required on the top end of the engine.
