5 spd tranny starting to go
my 97 5spd is looking like she'll be getting a new tranny soon. I've been wanting to do an lsd swap, but wanted opinions
lsd or 6 spd?
looking for opinions from those who have done either or both in a fourth gen. pros, cons, cost factor. just looking for advice to base my decision

An HLSD 6 speed would be the ultimate, but even a regular 6-speed open diff would be better than a 5 speed with VLSD. The closer gear ratios, and more of them, offering faster acceleration AND better fuel economy, would trounce the added cornering grip that going from an open diff to an LSD provides. Of course any 6-speed swap will be more work involved than a 5 speed.
My previous Maxima was a 98 5-speed and my second is a 98 I30 5-speed. So I went from open diff to vlsd. Differences? Yeah, but not night and day. The VLSD would benefit someone who drives aggressively alot, or drivers in Canada with long winters and slippery road surfaces.

i do most of my own work if i have time and tools, but ill be honest, I'm an electrician, not a master mechanic

I will let others with more experience chime in as I've never done the swap myself.
Also keep in mind that part of the reason the 6 speed swap is more work is because you are modifying the rod shifter mechanism of the 5 speed to a cable shifter mechanism of the 6 speed.
Nissan made some effort to suppress the NVH of the bigger VQ35 engine.....cable shifter.....dual mass flywheel.....etc
The VQ30 is killer smooth NVH so you can happily stick with single mass flywheel, and perhaps even "downgrade" the cable shifter to a rod shifter in your 6 speed install, although I don't think that has ever been done.

i think at the moment I'm still leaning towards 5spd lsd. i want the swap to go smooth, and i don't necessarily want to be shifting more than i already am, Atlanta traffic can be a real headache
of course tho I'm still open to all advice and suggestions

nor does it ever snow in Atlanta

I was drooling over a 02 6sp sitting in the junkyard when I was doing my 5sp swap due to a worn out input shaft bearing. There was just too much work to justify the extra gear. From what I remember, the trany mount has to be welded or bolted on, the cables have to be run through, and then there is the timing gear issue. Between all three it just wasn't worth it. I think about that 6th gear every time I'm going 75mph and pushing 3 grand.

yo Acck Mang....am I reading your sig correct?? Did you convert an I35 to a 6spd MT???
Thats sick man.
OP,
Obviously there are pros and cons of each swap:
Stock would be the easiest replacement. 6 spd MT route most difficult replacement.
In terms of price, the stock replacement will be most cost effective option.
In terms of fun....sorry acck mang, I gotta go with stock. I like the gear spacing better with the 5spd.
Fuel economy definitely goes to the 6spd however. U can get maybe 30mpg highway.
It really comes down to how much work you wanna do. I assume you will be doing the work as no garage would ever guarantee this work and the labor costs would be astronomical.

-Jes.
Thats sick man.
-Jes it is.

-Depends on the time span, over a year a 6mt will be cheaper, if you just want the car running quickly and cheaply and don't have any long term commitments to it then 5mt is the way to go.

-Please tell me you're speaking from experience.

I want to edit my original statement.
A transgo VB mod 4AT is even better than a 5MT
6mt > me > you > the dirt > 5mt

ok, question, can a open diff 5 speed be rebuilt into an lsd? a local member has a good 5 speed open diff for a couple hundred, i would like to just straight swap and rebuild my current one
#16
oh and deCided 6 speed is out of the question, i daily this thing and i can't afford to have it down for long just for another gear, besides I've always had 5 speeds, it's what i know and love
i do appreciate everyone's input

Anyhow, I do understand that because the 6 speed swap is more of a challenge I would also lean to the 5-speed as well. Still, in my dream garage I would have 4th gen 6-speed HLSD with a conversion from cable shifter to straight rod. Now THAT would be just too awesome
#18
Really? You make it sound like you are about to learn a whole new type of transmission. Its just one more gear

the case is different on the VLSD from the open diff, so you would need at least the top half of the case, the diff, driver's side diff bearing and ring gear and bolts. it could probably be done if someone were dead set on it but it's way easier to just buy a VLSD. would also be easier to just accomplish a 6spd swap than to make an open diff trans into a VLSD unless you're at least moderately experienced at building transmissions.
