wanting new lsd, what to ratio to get???

hey guys im thinking of buying another diff for my ea, my cars a 3 speed auto, i got told the diff ratios are shit on these (as are the transmissions) so i want to upgrade to make it a bit quicker, i dont care about top end speed all the much, i just want to be able to get off the line quicker and have a repectable 0-100 time. any one got any ideas??

what model e-series came with a shorter ratio diff??? I would like lsd too?? if any one has any suggustions and knows what model it came out on feel free to add your opinion.

also how much does a second hand diff cost from a wrecker???

thanks guys and girls.

Re: wanting new lsd, what to ratio to get???

EF/EL XR's and Ghia's scored a 3.45 LSD
i think there is a 3.23 aswell. any higher then that with the 3spd and it wouldn't be fun :)

Re: wanting new lsd, what to ratio to get???

Some EB XR8's came with 3.27's as standard like mine before I changed it. But you cant go past a 3.45 for drivability and performance. Problem is where to find one in good condition!

Beware of going too high in ratio as you torque will be used up too early as you accelerate.

Anything between a 3.23 to a 3.45, 3.7's maybe should be fine for your current setup.

4.11 will get you awesome 0-100kph, but your revs at 100kph would be thru the roof.

even 3.45/3.7 would have it revving near 3 grand (rough guesstimate)

3.45 on my 4spd is 1900 at 100kmh, roughly 200rpm higher.

Re: wanting new lsd, what to ratio to get???

puttin 4.11 in a 3 spd EA is not really the answer for an everyday street car. Drivability would be of concern imo.

I reckon you would get a pretty big kick in the pants putting a set of 3.45's on a 3spd EA coming from a 2.77 or whatever.

Re: wanting new lsd, what to ratio to get???

I have had my car with a 3 speed and 3.23 diff. It was a huge improvement over the 2.77 diff. At 100km/h it sat on 2700rpm. I would not suggest anything much higher then that.

If you are not concerned with driving the car on the freeway, and don't care about rpm.. a set of 3.9's or 4.11's with a few breathing mods like exhaust, intake (cam would be good) will have you a nice quick car!

Re: wanting new lsd, what to ratio to get???

Ive got 3.08's (4speed Series 2 EA) and sit at arround 1700rpm at 100kmh, and still find it slow off the line, and as the 3 speed has the same 1/2/3 ratios as the 4speed i wouldnt go for 3.08's if your making a change. 3.23/3.45 would be the way to go.
