5AT Quaife install - I need 3.5 FD Gears

Hi, there have seen a number of threads talking about how good the Quaife ATB is and I want to get one. The problem is they don't sell/make the the AT version anymore. So, I need to get a 3.5 FD pinion and drive gear from a stock 6 MT. I have sent a few PMs with no response.

Does anyone have a 3.5 pinion and drive gear that they don't need because they switched out to 3.7 or 3.9?

My last resort would be the dealer, but I'm trying to avoid that at all costs...

Thanks in advance.

if you end up going dealer... you might as well get 3.7 - it is good!

Yeah, if I'm going to go 3.7, I would get the Nismo gears. They're about 60% of what the dealer would charge.

No need to go with deeper gears with a turbo. You don't need the torque multiplication you need. If traction is the problem, why not just invest in DRs and run them all the time? It will be cheaper than spending $2K+ on a rear end.

BTW, why do you think you need a Quaife?

if you are referring to the 3.7 on mynismo.com - that is a Nissan gear, its Performance Nissan... the price you see is the dealer price. the only expensive Ring & Pinion is the 3.9

3.7 is what they used in the 07 sedan, the new coupe, FX35, Nissan Frontier and a few Pathfinders I think.

EverythingG35 (which is a dealer too in Scottsdale, AZ) has the cheapest 3.7 I found, $406

I didn’t realize he was TT, until you mentioned it (I should have read the sig)

OP he's right... with TT 3.3 is what you want... or some FI are looking into 3.1 even... there's a thread out here or on my350Z...

Quaife is a great option! Maintenance free, no noise, lifetime warranty, VERY streetable! You really notice it when you haul @ss around corners! I take corners at 3/4 throttle with barely a screech - then it hooks and goes!

Everything you read about Quaife is true, it really is a good diff. Expensive, yes - worth it?... the more I drive the car the more pleased I am that I got it. There are many other things to get first (IMO) but if you are open diff you really need something and Quaife is a very good choice.

The problem is getting the MT Quaife into my AT rear end. The only way to make it fit is to get the MT gears in there too. The lowest MT ratio is 3.5 so I was looking for those. I would certainly go lower if I knew where to get them.

PM helldorado... he is well versed with this... if there is a way he'll know.

But you are right, AT version of Quaife is hard to find and you make a good point about the current ring&pinion not fitting with MT Quaife... I'm not certain but I think helldorado is FI and went even shorter gears than 3.5... someone did and I think it was him... not sure he's still running that way though.

I agree, they're "it" when it comes to LSDs. They staight up hook around turns and can cure peg-leg launches if your car has that problem. They are very expensive though. If it was me, I'd buy a 3.5 VLSD differential off of my350z.com or carparts.com and see how things are with the OEM VLSD. The OEM LSD doesn't have near the torque split potential, but it's better than nothing and it would save some money initially. If it wasn't up to the task of your demands, then I'd look into Quaife. I think the VLSD should do fine though. I still think the 3.5 gears are a bit too deep for your application, but you really have no choice. I definitely wouldn't do a 3.7 gear though.

It doesn’t happen often, but… I agree with everything you posted... Not a first, but very rare

Bang for the buck I can’t honestly say Quaife is worthwhile. It IS a great asset to my car. Can’t really compare it to an OEM VLSD because I've never had OEM... however as with everything I have done with me car (and most things as a hobby) I researched the hell out of it... not just on these boards... Quaife America (AutoTech) and UltraRev probably hate my *** because of all my questions (even though they were super friendly and supportive ever time I had one)...

Generally speaking an OEM VLSD is more than enough for most people... if you are like me and figure hey, I need to add this (whatever the addition may be), so I might as well get something that is quality has great performance and will last... then Quaife is a great mod.

If you want to run the hell out of your car on the street and dump it in a couple of years... Quaife probably isn’t for you.

If you are NA AT 3.7 is a GREAT - I MEAN GREAT!!!! MOD~ No doubt it's one of the best things I've done to this car...

If you are MT shorter gears are probably going to result in better happiness... If you are FI - I'm not going to go there (because I'm not FI) - but it's sensible that what others have said and logic follows... taller gears are a better choice (I’ve only known of one FI car to differ).

DAMN...love my 3.92 gears...with the Vortech and lots of goodies...it rocks.

I think a Quaife is way overkill. The factory VLSD is well more than enough, unless your hard tracking the car.

Quaife is "overkill" or “over priced”?... It is a very mellow, extremely streetable diff... Nismo or Cusco might be overkill... I really wouldn’t say Quaife is overkill...

OK - so I wouldn't 'say' that either...depending on the application.

The OEM VLSD is MORE THAN ENOUGH for daily driving, 1/4 mile and street driving/racing, etc. Actually, is mostly perfectly fine for canyon driving and some tracking as well.

The only people who need more than the OEM VLSD - are those who regularly track the car, are looking for times and race qualifications - you know, those who take tracking seriously.

If your on the street, running 1/4 miles, and hitting canyons once in a while...there's no need to drop an extra $800 - $1,600 for a new diff like that, or at that level.

If it's for bragging rights - well to each his own and their own money. Besides - nobody would ever know you had it other than you to begin with. It's not like turbo's or SC's - where you know they are there.

Again - it's a great diff - no doubt about it - but at least make sure your getting it for a real usable reason, a reason you know will actually compliment the way you will be driving and using the car.

Just advice - not trying to argue...

Rick

Rick, even though it might not seem like it... I totally agree... I used the phrase "over priced" instead of "over-kill".. for basically the sanme the reason you did.

It's not "overkill" performance wise... In fact, there are better cost-benefit options for the track.. I prefaced my use by indicating if you are open diff, you may as well have something that is long lasting that won't cuase problems down the road (not verbatin, but I think if you re-read it basically states that)...

Let it be known - Quaife is an expensive mod. I have not minced words when stating (in every post I've made about it) that it really isn't the most cost beneficial mod to be had...

I am ABSOLUTLEY not the kind of guy that goes around with as trumpet about what I have that you don’t. Period. End Of Statement.

I love when I can get viable, real world opinions about certain things I'm interested in... If someone would have phrased the 3.7 and Quaife to me the way I have in the threads – I would be so much more comfortable with what I did...

I even had a suggestion to "not tell anyone what I have" while I smoke their @ss.....

I LOVE, LOVE LOVE making our cars perform better and am more than willing to share my {meager} experience with people...

I have no endless pocket of money so what I have done to this car isn’t anything about look at me. In fact, most people that know me or my car will concur it isn't about what I've spent - but it is unique and will surprise you.

There are boatloads of cars that have spent WAYYYY more on making their car look a certain way... I will smoke 'em.

So Rick, please don't post upon my review of performance mods in a way that implies that money is why it exists. I have $80 mods, and I have $1400 mods... The price has nothing to do with the value.

Thanks
~ Mike

Mike - we're on the same page....I wasn't challenging anything..sorry if it seemed that way.

I agree completely with the way you do things - I do it that way to. I have mods that are from $5 to over $5000 on my car. If you looked at pics of my car, and know me and my car, you'd never know it unless I stepped on the gas too.

My car looks stock - but that's only the skin. The guts will blow most away, if they had the knowledge. I've considered many times getting a plate that refers to being a sleeper...that'll spoil the fun later though.

So, no issue here - just trying to be objective - my post was not at you Mike, just a generality of my opinion on the OP's desire.

Rick

Oh by the way - OP, if you go with the Quaife...you'll love it...I know I do
