Best manual box for behind the Au I6 ?

[borry]

hey guys,

just as the thread stipulates, what would be the best, most cost effective box to put behind an "eventually" modded I6 ? at its got a slushbox, which i hate! i have seen two mechanics, both saying a t5 from an XF would be your best best, being both cost effective/decent box...

anyone with better ideas ? or anyone who has done it and wants to let me in on any tips to changing the boxes over ? we will be carrying out most of the work ourselves....hopefully!!
