2G: REAR LSD insert / no bolt design

But I don't know what additional info I gave you, I figured it was pretty easy to see what I was talking about in my first post ...



I don't know about that, I know I said there is a lot of snow here but I really doubt the entire body will get hung up and ALL 4 WHEELS off the ground. At least 2 wheels will be on the ground and once again, that's why I want more traction odds with LSD in the lightweight rear axle. I don't know how much simpler I can be with that ?

In your first post it sounded to me like you wanted to build a 'rally' car with the whole "mud slipping/climber" comment, and since you didnt say "hey i want to keep my car from getting hung up in the snow, will an LSD help me" or something like that i could only answer how i perceived your post. You know, diff'rent strokes thing, i say poe-TAT-o, you say puh-TOT-o.

Its possible if youre going fast enough (like i was into that parking lot) that you can get hung up, i know it happened to me. I cant answer for the speed bump issue though, we dont have enough around here to worry about. Like i said an inch or so is all you would need, and maybe only in front of each front wheel, you could hide it well enough and the AL wouldnt rust and is cheap enough to replace once a year if you had to. SAAB does/did something similar on their old 900 series, not sure if thats what they were for, but it made sense to think thats what they were for.

I suppose they wear out, but the rear VC doesn't actually do much work very often, so it will probably last long enough.

While the viscous is open until a speed differential locks it. I forget how that works during a turn though

Yeah, most clutch-packs have some preload, so I suppose that isn't the best argument against them. But if the preload isn't enough to get you unstuck, you're, well, stuck, because you won't be able to put enough torque through it to get it to lock any more. Seriously, a working VC is rather good at getting you out of a snowbank. They key is to not wimp out. You stay on it until it heats up and starts working both wheels. A lot of people give up too soon, never get the thing working, and then complain about how lousy VCs are.

With all that said, if you occasional drive seriously on pavement, the Evo diff will be better. My suggestion of a VC is mostly if you want something aimed at getting unstuck.

I don't feel like reading all this thread but I speak from experience driving a 1g with a LSD rear one winter and another without the LSD the next, and it is day to night difference between the cars. The LSD makes the car a freaking tank, plowing snow and never getting stuck while being quite tail happy and the non-LSD, while still capable, it would under steer a lot more and at times spin one front and one rear.

GET A LSD!

Hey guys, quick question

I have a manual 97' GSX with the BFB non-lsd rear

I found a guy selling a 2G auto LSD rear, it's just the pumpkin, no axles

I know the end ratios are different. Is there a way to fit the 2G auto LSD diff into my 2G manual setup by swapping internals/reshim?

Do I need the passenger LSD axle?

Thanks, I couldn't find the answer around

If it was possible im sure you would have to swap the ring and pinion gears from your non lsd housing

and i actually dont know if that will work, but if it did you would need the passenger rear axle


and how does mrpopups have over 300 post. it looks like he should be banned by now with the his stupid posts let alone the bad info

[NHerron]

I actually did find out last night some info that non lsd axles are different from lsd axles. Like a different spline count, but can someone confirm that?

I dont know what MrPoppers deal is but there is nothing but trouble when he drops by in a thread

[NHerron]

Still looking for confirmation on the swap, do I need both axle assemblies or just the one passenger side assembly? I decided to go with the stock LSD BFH diff and would very much appreciate someone with recent experience on the swap confirming the info that I'm looking for

To recap, manual trans 97' GSX with stock BFB (non-LSD) diff. I want to swap out for the BFH (VC-syle LSD) diff

I hope to make an article of the swap so any useful info would be just awesome. Thanks and happy holidays
