only the wheels, the front driver side axel, then the exhaust, the starter, the slave clutch cylinder, the air intake, the battery , the I got access to the tranny. I just emailed jimwolftechnology to know if they have a compatible clutch upgrade or flywheel upgrade since It'll be easily accessible with the tranny out . I'm going to try it out when it get hotter and the snow melts away.
I just got a reply from them:

"The 2008 Altima uses a smaller input shaft in the transmission than the 2002-2006 models and as a result, our JWT performance clutch for the 2002-2006 3.5L does not work. We are working on a clutch version for this. The earlier model JWT flywheel will fit but since the original clutch disc is a solid hub and our solid flywheel (original is a dual-mass design), is going to need a disc with a sprung hub, you would not want to install our flywheel without a sprung hub type disc used in place of the OEM. I will save your E-mail and advise you when we have a clutch to work with this smaller transmission input shaft in your transmission."

it's great to know that they are working on a clutch for us

finally JWT is getting to work on our cars. ive been dying for a new clutch, this OEM clutch just doesnt cut it some times.

btw, what tranny swap are you talking about, or are you talking about the diff?

well to get to the diff you have to take out the tranny. and I was refereing to the fact that the tranny removal process is the same as the old maximas so I can use their DIY tutorials . then when I remove the tranny I can open it to swap the diff.

You're going to try this differential thing? Kudos. Let us know how it goes. $500 isn't bad at all for more efficient power transfer to the wheels. Good luck!

I'm going to try this summer, because of the cold and snow but if anyone wants to try it should definitely work like the diagrammed showed. unless something else that I didn't think about comes into play

Ok guys, I called Dave Brunette (the coolest parts guys ever from nissan)and he gave me a great price for the HLSD and I ordered it. should be here in one to two weeks but I doubt I'll be able to install before carlisle.

this is soo cool!!!! byebye understeer, tire squeal and torque steer! (even thought there's not a lot of torque steer on our cars to begin with)

lets hope everything works as planned!

Hey, if you could do a full write-up and take pics when you install it that would be great. I've put an LSD in a Honda so I have a good understanding on what to do but if you're going to do it and put it in a guide would be perfect. If it works perfect for you I'll probably go get one as well.

cheap and loool you already asked the cvt question in the 2ND (!) post on this thread lol haha

but to answer your question, no it still won't fit the cvt because it's a completely different tranny. the HLSD goes inside the transaxle and is made to fit specifically in the 3.5SE 6MT's tranny.

yeah the part is from the SpecV 07+ sentras

I'm pretty positively sure the 2.5's 6MT is the same as teh 3.5's 6MT!it's only the 2.5's CVT that's different than the 3.5's CVT

hell yeah my 6MT brothas

good luck with the installation... Cant wait for the results

Is this a worthwhile upgrade for the 2.5? due to the significantly less power output...

well if you have enough power to understeer in a turn because you're accelerating too much, or to make your tire squeal at launch because you're giving too much power, or to make your car torque steer, then an HLSD is a worth while upgrade without a doubt.

Mheddi,

That is the exact same looking part as the one I got for my 3rd gen altima. The part was from 02-04 6 speed max. I recently sold it. Im sure the part #'s are different, but I wonder if it indeed is the same part?

When i was researching mine there was a Sentra se-r spec v diff with a differrent part # than the Maxima diff i had installed, yet it was the same exact part...

the old sentra and maxima where compatible between each other but I don't know if the new 07+ specV and the 6mt altimas are compatible with them.if they are then I guess it would be great. if you can get the diagram of the 04-06 maxima we could confirm if they would physically fit and the only thing left would be to see if the axels have the right grooves that would slide in the diff. whats the price range of these old diffs?

Depending on who you order from.. 500 -700.

You will also need the two bearings about 30 a pop if i remember correctly.

I order from pinnacle nissan in Arizona. Best price by far!

Ok! I just finished removing the tranny! was relativly easy with the powertools (read: IMPACT WRENCH FTW)

noticed one gasket was leaking for the engine coolant before the removal...that explains the almost non existent amount I had before Carlisle. I'll get that fixed underwarranty later

Took 2hours and a half to remove the front subframe, the y-pipe, the front axles, the starter motor, the intake and the two wheels + wishbones.

I got 130pics, I'll upload later. tomorrow we are opening the tranny and swaping the diffs! can't beleive this is happening! First HLSD equiped altima coupe IN THE WORLD!
