Guest Anonymous Posted November 22, 2000 Share Posted November 22, 2000 Ok i found the gear ratios on the 4N71B tranny(1st 2.458, 2nd 1.458, 3rd 1, O/D .686) with a 4.11 LSD rear and 225/55/15 tires my acceleration should be just as fast as a 5speed car(the gearing would be shorter) and my topspeed(if i could run it all the way to 6000rpm in topgear) would be 156mph. now does anyone know what cars had the 3.90 LSD or the 4.11 LSD rear???

jeromio Posted November 22, 2000 Share Posted November 22, 2000 No such rear. See the drivetrain forum for Mikelly's travails in trying to locate/build a 4.11 LSD. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted November 22, 2000 Share Posted November 22, 2000 yes there was a 4.11 rear it was in some 240sx turbos(but they are real rare, and in turn a 4.11 LSD would be too much money. i need the 3.90 LSD or open diff.(money has cut the x-mas list a lil bit) so what cars besides the 81-83 5speed had a 3.90 diff at all? i would still like an LSD but i'll take what i can find(or afford) what cars had the LSD and how do i tell them apart?

Drax240z Posted November 23, 2000 Share Posted November 23, 2000 My advice is to find yourself an R200 3.9:1 open diff and go with that for now. If you end up finding an LSD later on swap it in then. The 3.9:1's are probably the most common ones out there, you shouldn't have to pay too much. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html Quote Link to comment Share on other sites More sharing options...
