Yep. All 3.9.

2.6 got 4.22, which gives slightly better acceleration if fitted to a 3.2, but slightly higher rpm at motorway speeds.

Sideways mostly if the LSD kicks in, but as pointed out once you get up to decent speed then its the same as yours but you have to move that stick around until you find one that works.  ;D ;)

Although on a serious note, and being a Manual and assuming I can retian the LSD Clutch Plates, Im tempted to fit a 3.45 ratio and see how drivable that is and wether it will improve the 3.2's poor mpg figures.  :-\

Where's 2woody? :-\

Suspect it will depend on the type of journey. If stop start in town perhaps an improvement as less time spent pressing the loud pedal.

If long run at motorway speeds, I'm not sure if the higher rpm will worsen mpg. Certainly on an auto, changing from a 3.9 to a 4.22 sees an increase of about 400rpm at 80mph. Which doesn't sound much, but can be slightly irritating.

It does go better and pull a higher top speed quicker. The 3.9 takes forever to get there. Your honour. :-\ ;D
