hi guys.

quick question, ( i tried to search and didnt find a proper answer )

Stock open diff.
+
quaife L11 ( manual diff )
=
works perfect.


now if i want to change the ratios with an auto. from 3.5 to 3.3 .. do u guys think it will fit ?!?!?!

what is the difference between a open manual pumpkin and open auto pumpkin ??!! only the ring and pinion or something else as well.


thanks guys.. your input is appreciated.

 

It's only the pinion and crown gear that differ. Yes it will fit; plenty of people have done it.

 

why then quaife have different part for auto ??

does that mean i wont be able to use my lsd ?/?

 

im doing the same thing, is there a difference between the 3.3 and the 3.5? driving wise? i have a 6spd base and the donor has a 5 spd auto touring.

 

So no one installed it on a 3.3 !?!?!?!?!?!

 

I have a Quaife and the 3.3 auto gears from a G35. I did a complete pumkin swap, so I am using the G35 auto pumpkin. I was unaware the there different Quaife parts for auto and manual, but the pumpkins appear very similar from the outside, so it should be fine plus many have kept the stock pumpkins and just swapped the final drive gears. You could always check with Quaife directly to be sure.

The difference driving wise is that it allows you to get a bit more out of each gear because its a longer ratio. It is especially helpful for the +500whp F/I guys because it will help a bit with traction as the boost comes on too. I liked it because in day to day driving it meant not shifting quite so much a speeds under 35mph.

 

Thx for the input.


Would u be able to check if the one u have is the manual or the auto quiafe diff ?!?!

Thx alot..

 

Bump !!!!! Anyone ?!?!

 

I would have no idea and the car is 3 states away currently.

 

3.3 ring gear is larger than the 3.5.....my shop built a separate base pumpkin or my 5 at, and we discovered the diffeence, so now Im stuck with the 3.5 or having to buy a new auto 3.3 quaife

Call quaife as suggesteed and tell them what you have and what you plan to do, ***, yes, they have many different setups.

Dont screw yourself like I did....I thought I knew what I was doing but didnt..ASK QUAIFE FIRST!

 

thanks for the input!

 

As it's been stated the 3.3 ring gear is thicker and the diff is different because of that.

Here is a pic I put together to help show why you'd need a different diff. to go to a 3.3 gearing:
