just found this on ebay..
excuse my dumbness,
but does this mean it will fit a t18 diff with a 2way lsd?
i apparently hav 4.1:1 in my car atm with a 20v,
would 4.3:1 be alot more punchier or would it be better
to go to 4.5:1? keeping in mind its also a daily driver http://www.ae86drivingclub.com.au/forums/emoticons/wtf.gif

yes it should fit a T series diff.

the 4.5 would be very godd acceleration and 'punchier' but it will be screaming at 100 km/h if you have to drive on freeways and the like.

it think it would be sitting at 3500 revs, not exactly screaming for any 20v
