you need to order a manual differential from a 370z g37 350z or g35 gears will not fit in the auto housing..i bought mine from ebay

Thanks for reply
Should I order complete set with pumkin or just LSD ? Then how its going to happen, I'll swap my LSD inside Manual transmition pumpkin?

this is what you order.. it will come with a stock LSD..but when you put the new gears in put the new LSD in at the time.. while you have the pumpkin drop I would also do bushings

Thanks again, now its clear :tiphat:

I have a base. I'm doing it. I'm just waiting on my Quaife 1.5 LSD, ACT Clutch and flywheel, exhaust, HFC's CF 1 piece driveshaft and tune...car would be beast! I hear the 4.08 alone makes your car a beast tho...

if you did a dyno before you put your gears in those numbers will change.
with that being said you will notice a huge change in acceleration off the line and the first few gears

I wouldn't say it makes the Z a 'beast'. I'd say it makes the car more responsive, and fun to drive around. Great mod of course.

4.08 Gears
