Better question, who's listening?

I knew this would be one of the best mods. Problem is that autos might have to find a new pumpkin (more money) and the stock LSD has a bad reputation for effectiveness, durability, and longevity. I'd want to swap it out for a better one but they are so damn expensive.

Was it just the autos that had the issue with the cruise control or both?

 

Did you order through Nissan wholesale, or did you order through Z1Performance? Any issue with the shims or were you able to reuse the existing ones?

I do know the 4.08 Gear is also in the Nissan Frontier trucks.

 

If I remember correctly it was only the autos that had their cruise control stop working with this mod. The pumpkin can take it but from my experience with the 3.93 gears the stock LSD isn't going to hold much of anything after these gears especially if you are looking at this from more of a drag race launching perspective.

 

Yes, where did you order the part? A direct link would be great!

Thank you for finally installing this and for the review

 

Damn after reading up on the Z forum about this me WANT. $1k ain't bad for what it provides. My only concern is the long-term effects on the LSD, but we really haven't had the G37 out long enough to know much about that have we? I'd hate to have the LSD go out after 10k miles b/c of this. Is the G37 LSD better than the 350Z?

 

That's exactly what I expected. Part of that logic is true but they are leaving out about a dozen other factors. To say it's good for a SC and not a turbo is just wrong.

 

This is nothing new in the world of hot rodding. Gears are a major component in the drivetrain that gets just as much focus as any other part. The tuner community has been lacking in this area for a while.



This LSD has been out for a long time now. It's not new to the G37. It is known to be ok at first, weak if pushed hard, and become very ineffective as time goes on (not a lot of time either).

 

The increased acceleration will get the turbo into it's powerband faster and then the biggest problem is traction. I wouldn't worry so much about shifting taking the guts outta the boost.

The difference with the Z was throttle response was immediate, where in the G it is very linear. If you back off the clutch and stomp the throttle on a 350z you will spin tires, if you do the same on the G it will bog quickly then ramp up its throttle progressively.

This makes the G feel a ton slower but given that he throttle output on the G is the way it is, I think it would be a very good candidate to try it out on. Regardless a turbo + gears is going to be faster but it is traction limited which is why as the HP/TQ goes up they scale back on the gears on the 350.

 

I am using the frontier 4.08 gear.

 

I bought it through The Nismo Shop. They will price match anyone..

 

IF it is installed correctly your stock lsd will be fine .

 

Well, there is a ton more to talk about. Here is my issue with some of the comments. If you are running a centrifugal supercharger, lower gears (which is a higher numeric number) helps get the rpms up faster which the SC needs to make boost. If you have a positive displacement supercharger the boost is almost instantaneous so the need to ramp up the rpm for boost is not there. Of course, there may be other factors for going with lower gears like tire size, weight, driving habits, and many more. To say that turbo cars do not need lower gears but sc do is just a wrong thing to say. And it's said all the time on these forums, that's my issue.

 

I honestly do not know how this mod is so over looked . There is such a difference in this car now..

 

I was just quoting what others have said on other forums. Much like yourself, I like to do research on topics that I find interesting. My350z and g35driver have been sources that I've frequently turned to for explanations, experiences, and etc. Those guys simply have had more time to try different things with their cars.

From personal experience, 0-7k comes very fast on a TTed G37 in first gear. The car becomes very tail happy, especially on stock tires. I think a 4.08 gear will only exasperate the traction problem. Plus, I can only picture the MPG getting worse as a result. I guess the same will apply to a supercharged G37.

I picture this mod to be more beneficial for N/A owners.

 

Anyone have a DIY on this. My dad changed out the bearings on his 01 Ram. He had the entire diff in pieces and I thought he had gotten himself way over his head. 6 months later and still no issues. If he can do it I'm sure I can do it as well... Mainly what are the torque specs for the bolts back there?
