C60/C160, 6 speeds for A series Options

[JoKeRkId613]

I'm about to install the Super 60 turbo in my car as soon as I receive my FMIC, BOV, and SAFC-2(should be on their way). I'm also thinking about the future tho because I know the 7AFTE wont last for long cuz it has a crap load of miles. So I'm thinking maybe going 6 Speed and later swapping the blacktop. I SEARCHED and found that there are 2 good 6spd trannies for the A series. First, I need to know the difference between the C60 and C160 tranny. From the search on 6gc, i found that the c60 came with available lsd and the c160, i know for sure comes with helical lsd or sumthing. thats not a difference tho. lol. i mean, is there anything else? also, can i put a c160 and use it with my 7af(t)e? i would need the ecu for that tranny, i assume? let me know. thanks.
