It will work with ATR U2Q7 box as this is a torsen type diff similar to Quaife LSD.
great thank you for clearing that up although on there website it does say it doesnt work with any oem lsd
Trust me, they work just fine with OEM U2Q7 ATR diff - fitted enough of them...including Dino's :D
It is ONLY the viscous diffs that they won't work with as the crown wheels are totally different

My housemate found this yesterday while looking for the M2P4 ratios and which engine it was mated to.

Correctly confirms the H22A5/A8 differences.

James,

Again, that list shows the EUDM UK Prelude having a 4.266 FD and not the 4.062 it actually has.

So I dont know how accurate the rest of the ratios are on that list buddy

:lol: it keeps coming round. but most are fine, its just a couple that are wrong. i think one of the 2lt boxes is the main one that is incorect as its geared for around 190mph :lol: be wary of the stated final drives :D

So if swapping a UKDM M2F5 4g box for an M2B4 JDM LSD box you gain a shorter F.D as well as the diff?? Is this right?

Sounds like a win-win to me!

Does anyone know if the ATR FD and LSD fits into a M2V5 box? I have the crappy 4.062 FD in my manual box for my auto to manual conversion. But i have tested this box and it is smooth and has 0 crunches. If its a yea does anyone have them to sell?

Thanks.
