MFactory 4.6 or 5.1 into jdm h22a LSD gearbox

[bbds]

Hi guys, im looking to purchase a final drive for my h22a, im either going for 4.6 or 5.1 from MFactory. Just wanting to know has anyone else put this FD into there h22a with LSD, have experienced any problems?

And also i have been reading up that the MFactory FD wont fit h22 with factory LSD. Could someone please confirm this?

thanks in advance

if it fits your best off asking Mfactory.
as for what FD your after will depend on what you want to get from the car, a 5.1 will make the car sit at high RPM on the freeways so u might want to also look into a longer 5th gear to counter that.
