2G LSD options EDM Eclipse

[Wizeman76]

I have a 1998 EDM FWD Mitsubishi Eclipse with an N/T DOHC 4G63 with an F5M31 transmission and I’d like to fit an LSD.

What are my options?

Its a 2G so should be 27 spline inner cups, so you in theory can use the quaife QDH7B

If its 25 spline you may be able to jse the awd diff as they are 25 splines QDH8B but this would need to be confirmed and quaife have drawings for it all.

What power are you currently? I dont think a diff is needed till at least 300hp and being NA i think torque is not enough to warranct the cost of a diff vs results unless your racing then its a different story. But for a road car at lower power levels the stock diff will be ok

It's stock at present, but I am changing the clutch as it barely moves. I thought while I had the gearbox out, I may as well look at LSD options. Save me doing it again in the future.

I was looking at this:

https://www.ebay.co.uk/itm/OBX-High...745642?hash=item2889eda8aa:g:Oi0AAOSwXrldufaw

But the seller says it wont work. He/She was a bit vague in their reasoning - what are your thoughts on fitment?

There's very little confirmed info online regarding the options for an F5M31 gearbox LSD.

I'll pull the box and then I'll know how many splines.
