Dave might be able to help you (David... yes that's his nick)
I'm pretty sure mine is 3.9:1 though, and i thought it was stock.
I could be wrong

Steve

I think you're wrong, or it explains why your car is quicker than mine. That and more cams, computer etc.

hmmm
how do i find out?
there are alot of reasons why my car is quicker al :P

steve :D

3 ways.
1. Open the diff and count the teeth on the crown wheel and pinion. Divide the bigger number by the little number.
2. Next cruise, drive side by side with me in 4th gear (1:1), and see what the revs are. If they are the same the diffs are the same ratio.
3. Jack up the car, mark where the tailshaft is. Turn the wheel around 1 revolution. Note how many times the tailshaft turns around. If it's almost 4 times you got a 3.9. If it's about 3.5 then you got a 3.55.

Drive at 100 in 5th, if your revving about 3k, then you have 3.9:1 sexyness.

Yeh it sits around 3 grand at 100km/h in 5th

AFAIK, it's 3.9:1 in your Starion Steve... That's what Mark Cherriman said, and I don't see any reason to disbeleive him.

As for ratios?

Not many choices for JA. I think you may be able to get a different ratio from a Scorpion diff though.

JD housing is larger. - Combinations to 5.1:1 or something similar.

Ron (Coltspeed) is the expert. He can rattle the ratio's off from the top of his head. Can probably change your diff too.

I have a 4.6:1 ratio in a JA housing. I beleive it's a Pajero diff cut down to fit the JA housing. But then, I have a *very* modified diff housing, including pickups for the diff cooler.

Yours is a 3.9 LSD stock Starion diff Steve.

Sorry, i should have made mention of tyre/wheel size aswell, the 3k @ 100k thing will only hold true if your tyre/wheel combo diameter is similar to standard.

Anyone know where i can find a 3.9 ratio diff to go in my 86 starion?
Would be very keen on one.

They can be found in the same aisle as the hens teeth and the leprecons with their pots of gold.

Apparently you can swap the LSD centre from a light mitsu truck and put it in the non-lsd case (JB/JD one would assume) But the centre has to come from the US cos that's where the trucks live in the first place. Oscar-the-Grouch has the conversion on offer. Or if you are keen, check what mitsubish vehicles offer in the way of LSD centres and get your tape measure out.

Ok thanks for the help.
Im wanting one for drag racing, would be much better than the 3.5 i would think, although doing 240kmh in 4th gear is all good haha

240kph in 4th?
