Wait, if you already have 3.692 gears, what are you swapping to? I thought you said you didn't want to do 4.08. I took it as you had an auto with 3.6 and wanted to swap to the 3.6 of a manual.

I need to check my notes. I thought the 7 AT had 3.3 rear end gear.

I have the 7 AT. According to my notes the rear end gear 3.357

I want to swap to 3.692 vs. 4.08.

Yes, I believe so. Do you have the VLSD? If you swap in the MT VLSD pumpkin, that's all you need to do. Not sure if VLSD or open diff. is a factor though. The pumpkin I have is a VLSD MT one that had a quaife diff. in it. No need to go to 4.08 FD gear.

sorry, read it wrong. Thought you said you already had a mt. Yes, the pumpkins will just swap.

If your car has vlsd then you need a manual with vlsd. If not, then no.

No VSLD in the base coupe. I have been looking at the caronetics VSLD. I should do it all at once if I pull the trigger on the 3.692 gear.

Well, if you're just swapping pumpkins, you can id without an LSD. They're not opening it up. If you're changing gears though, then you can save a lot of labor costs y installing an after market diff at the same time if you plan to go that route. I don't plan to so I didn't. However, if I do decide to, I will regret not doing it at the same time I had the 408 done.

it doesn't matter if you install the vlsd or open carrier if doing a pumpkin swap, the 370z stubs all have the same flange for the side axles so if you swap the whole pumpkin and stubs together it will fit. only diff you can't put in is the g35/g37 sedan as the driveshaft only has 3 bolts. also remember if you get a 350z or g35 differential you should change out for 370z stubs because the abs rings have different numbers of teeth between the two generations.

hod did it go? Did you get it worked out?

this guy knows his stuff lol

It was actually really strange. It worked the first time I tried it when I left his shop, then after I turned it off and back on to try it again, no luck. So it didn't fix the cruise on my car.

sorry to hear that. I tried mine twice and it was fine, but I will try it again the next time I am cruising on the highway to see if it is still working.

Guys, I drive a 7AT (2010 Roadster) and I want to swap to 4:08. Is this the pumpkin I require? New 03 04 05 06 07 Nissan 350Z 09 10 370Z Differential Case 38410 2C500 | eBay

Please advise and thanks in advance!

That's the carrier, not the pumpkin, which in most axle assembles is all you need to change, but I guess Nissan decided to use different housings (pumpkins) for some reason http://www.gixxer.com/forums/images/.../confused1.gif Still stying to get a handle on the Z platform myself
