Hey guys im changing the diff ratio in my ef to 3.7.1 to give it a bit more stick of the line, the car is a 1996 EF automatic, just wanted to know if i do this will i kill anything? eg gearbox etc, would it be ok to change the ratio in the stock diff or should i get a lsd? ive talked to various mechanics and they all said that they can change the stock diff gears to 3.7.1 if this is true then i would really like to go ahead and do it, but im just not sure as i dont know much diffs and such.

Thanx

Simo....
