6MT with 3.53s?

esfourteen

I run the 3.53 with a Quaife ATB LSD, cruise and SRM work perfect (about 100rpm off). I'd agree that over 500whp the 3.3 FD is probably best, but the SRM will be ~300-400rpm off (same as going to 4.08) and as Squeeze mentioned, cruise won't work.

Why does cruise not work? Is it because of the speed/rpm mismatch? I would think the computer would just hold a speed.

Esforteen - where did you get your setup and would you recommend it?

I put it together myself: used 350z open diff, quaife ATB LSD for an open diff, new bearings, seals, and shims from nissan. It took about 4 hours to put it together and properly shim the diff, if you're mechanically inclined It's a fun project. I love this setup, but going for 600whp I could probably use more gear lol.

As for the cruise control with the 3.3, I believe the issue is related to the RPM's being off since Squeeze mentioned cruise works in 5th gear for him.

Mr.Squeeze

My rear diff came from a 06 G35 automatic, you can use a G35/350 doesn't matter as long as its from a auto. The automatic cars are the only ones that come with a 3.3 final drive. This is a direct swap you take out your diff and swap in the other one.






I think it has to do with the speed being off for cruise to work in 6 gear.


If you have a OSG LSD already and it's for a manual car it wont work in the automatic diff. The pumpkin housing are the same it's the internals that are different ring and pinion.
