I had a question about swaping final drive. I have a 07 auto and I want to swap to a 3.9 or 4.08 what parts do I need?

This is what I planned:

- 4.08 FD
- Install kit (pinion Nut, pinion crush sleeve, and pinion oil seal)
- Cusco type RS 1.5 way rear LSD

would this work? is this all I need? what do you guys think?
Any help would be much appreciated.

 

You can probably do it but the rpms you will be turning at 60-70 would be awful high.I did the 3.3-3.5 swap and at 70 mine is running at 3200 rpms....i would hate to see how high yours would be.And the extra strain on the motor would not be a + in my book.

 

I believe the G37 Coupe with auto comes with the 3.7 final drive and LSD. Just buy the whole pumpkin. 3.7 should work better for the auto then the 3.9 or other.

 

Just some shims, you have everything else required, why not put on a Nismo
rear diss cover while yaor at it, its only another $85.00.
Looks like a great set up, I did the 3.5 swap with my auto and love it!
I am opting for the 3.7 and cusco RS next.

 

yeah i forgot to add that... hey how do you like the 3.5? notice a big difference. Could you give me some feedback with your set up.

 

bump!

should've gotten a 6 speed , but yeah im sure it'd work. thats the same exact swap im doing soon.

 

3.3 to 3.5 FD swap works for me in autocross. My '06 Z is awefully quicker than stock.
