nope...
but final drive ratio would change FC...where most LSD have shorter final driver ratio...means on long journey at high speed FC would suffer a bit
'most' lsd have shorter ratio? most also mean a lot. tell me one.
u wont suffer higher fc for long journey if u maintain average 3krpm, same goes to other car.
of course the speed is lower if u use bigger fin.drive (fd) and the bright side is u wont get speedtrap.
not really that way....
A - because the final drive was bolted/welded on the differential itself....so means if u change diff unit with LSD type..most likely it comes with shorter final drive.....no excuses....
B - even if u swapped gearbox....those LSD equipped GB mostly got shorter final drive....dun believe me u can google the gearbox spec.
C - maybe u can retain the final drive if your differential unit comes with bolted final drive tooth...(means can change the tooth)
a - yes its bolted/screw, not welded. ive never seen/heard someone welding their diff to the FD, i dunno about others.
"so means if u change diff unit with LSD type..most likely it comes with shorter final drive"...
exuse me, short mean what..4.1?? please explain 'shorter final drive'...bcos my layman term to describe FD is big or small. 4.3 is a baseline as we knew thats the stock supply for c52/56.
so big = >4.3 e.g 4.5-4.7-5.2 etc and small = 4.2,4.0,3.9 and so on....
b - i dont believe u. googling gbox spec for what as they normally didnt equipped with lsd while some does but it didnt change fd though.
people normally, change the differential unit only. FD is another different thing, unless it is welded together as u mention above. u can get a new set of kaaz lsd at some of the perf shop in here, and hey it didnt come with FD. if u swapped with other/different code of gbox (c52 starlet/c60) thats another story bcos they have different final gear ratio.
c - u dont need to change, just take out the old one and change the lsd unit...unless u have alot of different set of final gear. i believe the thread starter here refer to c56 ae111 gearbox...maybe its a different thing to RB's since u are the GTR pomen, or maybe it is defferent to other car/brand...or just like my friend satria since they have few different models and gearbox ratio.
just want to compare between other member here...
first thing is...i drive a 20v bt 5 speed lsd equipped (i assume factory equipped lsd) in a ae 101 corolla...on 15 rims...with 195/55/15 tyres...when traveling at speed of 120km/h engine rpm is around 4k...
come to think of it technically...if it were an open differential and have different final drive ratio...does the rpm have a comparable/noticeable different when traveling at the same speed on other vehicle...???
yes, if u change to different gear ratio. if chnage the lsd unit only it wont affect the speed at all. c52 at 3k rpm normally travel at 92/95kmh. its normal to hit 120kmh at 4k.
"Will LSD affect fuel consumption"
- this is kinda silly question but also make sense. i believe that the owner 'tHrottle power' is concernd about his gripping power since he get more traction by his lsd but somehow more or less it will affect the fc. for the believers.....
"Tyres effect fuel efficiency
It is estimated that about 50% of tyres on the road are under inflated. Aside from increasing the rate of wear, this wastes fuel and decreased your fuel efficiency. Check your tyre pressures every fortnight. Worn tyres will also decrease fuel efficiency (and your safety!), so check the tread regularly. If you are replacing tyres then consider some of the newer 'Eco' tyres that are designed specifically to increase fuel efficiency.

one more thing,
im not an expert. i am oso not a qualified person to discuss this 'gearing-ratio' topic since i dont have any certificate in engineering. so, my statement here is totally crap. happy discussion.
peace.
