I try searching but with no results my question is can a 6 speed MT fit on My VQ3.0 DE-K motor.... if yes what part would i need keep in mine my car is already a 5 speed manual.

thanks for the help

Why do you wanna go 6spd??? Just use the $$$ on a 3.5 swap...

i agree..with the modification you have to do to do a 6speed trans swap, you might as well do the whole 3.5 swap, but if you want to, its your choice. i do wish it was a simple transmission swap though. g/l

I wouldn't even be hard pressed for a 6spd anyways

Unless you have the parts available to you for dirt cheap or regularly cruise at 75+mph, don't waste your time with the 6 speed swap.

Its the same procudure as the 4th gen by the way.

this isnt an easy job...and no benefits to make it worth it

Christobal65

The 04+ 6spd has shorter final drive which would be helpful for acceleration in all gears even for a VQ30. Combine that with better gearing for 6th gear cruising at 70+ it could be beneficial. My mileage noticeably suffers when I cruise faster than 65 on the freeway. Course it would take years to recoup the cost of the swap in fuel savings. That being said if my 5spd trans dies on me I'll be looking for a 6spd HLSD to replace it with.

Also some of us cant do a VQ35 swap due to emissions.

Its a GIANT pain in the **** to get a swapped motor to pass emissions in CA.

Andd where is the benefit of using this "final drive" gear, unless your always doing some high speed highway racing then it doesn't matter, 5spd better for the 1/4 where u will probebly see more improvements and have the chance to take advantage of gearing.... keep the 5spd, no point in wasting the $$$

Final drive is the gearing leaving the transmission it effects all gears. A higher number means the gearing is shorter. Its why the performance diff in a Mustang is a 3.73 instead of the base 3.31. The 04 6spd has a shorter (higher number) final drive ratio. There will be performance gains in every gear.
I've lived in CA my entire life and have only ever felt 2 earthquakes

Grand_hustle17

5spd still better... this such gearing havent proven anything spectacular other than saying oh man i have a shorter final drive, i understand the mustang because the changed gearing may result in maybe a .5-1sec in improved times, in the maxima world its like how everbody is still hard pressed that the LSD trans improve 1/4 times but we still have no solid proof.. he might as well do that swap... a AE LSD trans

I understand what you're saying and I agree to an extent. From a performance stand point, in theory the 6 speed with the closer final drive will perform better. This is just common knowlege with cars in general..

But as far as maximas go, it doesnt make that much of a difference (from what we know so far) in performance to warrant swapping from an already nicely geared 5 speed. Cost and labor being the huge factor in this obviously.

Now going from auto to ANY manual tranny is a completely different subject...

Christobal65

What? you aren't even making sense now. You say the 5spd is better, but then say there's no proof one is better than the other. Then you say that shorter final drive is better.

A shorter final drive will increase acceleration (this is fact), but it could cause you to need to shift an extra time in the 1/4. In the 5spd 3rd takes you to 103mph. 02-03 6spd 3rd gear takes you to 95mph. And the 04+6spd 3rd gear takes you to 87mph. All with a 6500rpm rev limit and 225/50/17 tires.

So if you are trapping less than 87 mph in the 1/4 mi the 04 6spd would be best, between 87 and 95 and the 02-03 6spd best and between 95 and 103 the 5spd would be best. So for a fairly stock VQ30DE-K an 04+ 6spd should be an all around better transmission.

Now all this being said i dont really care about 1/4mi racing or straight line racing at all. I care more about how the car feels and for me a car with a shorter final drive ratio is more fun to drive. In reality I'll sell the maxima before I do the 04+ 6spd swap. That amount of work just isnt worth it to me for a daily driver.

Christobal65

Nah little older than 5. I grew up and lived in the Sacramento area most of my life, I did spend 6 years living in LA but only felt one quake there and it was a 4.3 iirc.

Grand_hustle17

iTrader: (22)

Agreed 100% auto to manual is a world a difference
I don't see how essential get it but you don't.... anyways lemme try to break it to you again, granted that the open dif and LSD has proven no performance gains id be more content and understanding to doing that swap vs a 6spd from a 5spd as that's a waste of money, the 5spd may fair better in the 1/4 due to having probebly a longer 3rd gear so you have less shifts possibly better times at the same MPH... take for example the 5spd altima vs the 6spd SE-R, no improvements on times due to gearing, so what I'm saying to the OP at the end of the day is to keep the 5spd and change the motor as that will give way more a difference.... my question to you is what's so much better in a 04 6spd vs a 5spd DE-K???...

Christobal65

First can you write in complete sentences? It is very difficult to decipher your sentence fragments, incomplete thoughts and poor grammar.

The 3.0L makes less power and less torque across the entire range, shorter gearing allows you to make better use of that power. Its the same reason that 4 cylinder Hondas have such short final drive ratios. Look at the S2000 it has a very short final drive ratio and gearing that keeps the engine between 6000 and 9000 rpm when you shift. The DE-K is very similar if you don't keep it on boil you lose a lot of power.

Christobal65

Also i'm not saying there aren't better ways to spend money modding these cars to get bigger results. I am saying that gearing is more important than a lot of people give it credit for.

VQ30MPG

Don't the 6-speed and LSD trannies also have more rotating mass? I would think that would have almost as much of an impact on 1/4 mile performance as the extra shift.

I wish there were an easier answer for a taller top gear. On my Saturn, it's a 1-hour, tranny-in-car, $80, DIY job, and the only downside is it makes the cruise control freak out.

fyi, 5mt and 02-03 6mt come out to just about the same outputs, but with the 6spd having a "cruising gear." the differences between their final drives and gearing would be negligible to most drivers. the 04-06 final drive, however, is quite noticeably shorter.

i'm misfiring, have a sub, 200 piece tool set, hydraulic jack (stock jack too), jack stands, full size spare, and still more random crap in my trunk and hang neck and neck with my friends 99 5spd sel. only mods are a sri, ws y-pipe and a 2.5" catback (crush bent, no res with stock cat). of course, i do have a 4.133 FD (not by choice, the max trans i bought had a chewed up bearing race).

EDIT: in short, if you REALLY want a 6spd, do it. if you want a better transmission, do it. if you want a performance gain, don't bother.

Here comes the grammer police if you can't pick up on sentenses like that then the internet is not for you bro man... again essential go it, you didn't.... I'm typing from my cellphone so I'm gonna use every broken language and slang I want to... if u can't understand just simply don't quote or reply to my post..... I did also say use a 3.5 on a 5spd not a DE-K so let's stop reffering to that... it will most likely cost the OP less to have a 3.5 with the 5spd trans vs a DE-K with a 6spd transmission not to mention a great power and torque increase.....

Grand_hustle17

iTrader: (22)

Nobody has proven the difference in 1/4 times between trans

Christobal65

You want to have an intelligent discussion but cant even spell grammar or sentence correctly....The problem is that it is very difficult to properly understand some of your points when you don't bother actually writing them correctly. You could at least break the major thoughts in to paragraphs as that would help a lot.

Also you seem to be under the impression that I said "do the 04+ 6spd swap instead of the VQ35 swap." I never said that. I simply said I cannot do a VQ35 swap in CA, and that if my 5spd was fubar I would probably replace it with an 04+ unit. Would I throw out a perfectly good 5spd for a 6spd unit? Hell no, that's just stupid. Though i'm sure someone would pay good money for my VLSD unit.

My point all along has been that an 04+ 6spd is a nice match for for the DE-K. I understand that you are saying there isn't a whole lot of data saying that the 04+ unit is better, but if you put the 04+ unit into a car already trapping between 87mph and 94mph then you wont see any gain. However in normal every day driving the driver of the car with the 04+ unit will feel that the car is peppier and responds faster. The physics and the math agree with me.

o.k lets end with the girly argument as this is pointless, i wont correct my half **** sentense so if you nor anybody else cant get it i quite frankly dont care, welcome to the internet where spelling, grammer, nor punctuations means shyt, i wont skim through some size1 font on my cellphone to spellcheck myself so whatever... in your last paragraph your saying that mentally it will feel better with a 6spd??? so your spending the cash for the mental aspect of the car feeling "peppier" and more responsive??? rather than the car actually being "peppier" and responsive???

so you know what im saying but choose to not understand cause it wasnt spell correctly??? your in the thread for the wrong reasons, again i (notice the "I" wasnt capitalized ) wont even spell check myself as if you see something mis spelled or some punctuation missing but cant use common sense to see what i was saying then thats on you i dont know how many times im going to say i dont care... welcome to the NET, im not in a area where my spelling should be judged, i could be as dumb as a bat, it doesnt matter, pick sense out of non sense,

nor do i know english or my first name but you seem more interested to let it be known more than me, and again i dont care.... SOOOO!!! to the OP in whom i was speaking to only, do a 3.5 swap vs the 6spd swap

Christobal65

This doesn't even make sense. Also, for someone who didn't want to talk about grammar anymore you do seem to be harping on it a lot now.


I agree if that swap is do able in ones given area it is a much better usage of funds for modding a Maxima. Course it could just as easily be said that its pointless to spend that much money making a maxima go that much faster as there are better options for a performance platform.

My whole point on the shorter final drive was that there is in fact a benefit from going with an 04+ 6spd. I also said in my original post that the cost wouldn't really be worth the benefit, and the only way I'd consider it is if the 5spd went out on my car.

The simple fact is that for a given gear ratio, say 3rd gear, one in a trans with a long final drive and one with a short final drive. The car with the short final drive will accelerate through that gear faster, but will have a lower top speed in that gear. This is not up for debate, it is a fact.
