5 SPEED TO 6 SPEED HELP
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

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

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.

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.

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 $$$
I've lived in CA my entire life and have only ever felt 2 earthquakes
#19
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
#20
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.

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...

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.

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.

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.

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.

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.
#27
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.

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

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.

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.....
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.

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.

I grew up in Anaheim but lived in Palmdale CA when the 94 quake hit aka Northridge Quake, it was 6.7. I was also in the 89 quake in San Fransisco.

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.

It was scary, just got home from a party at 3 am, was high and drunk. That hit an hour later. I freaked out. I could hear car alarms going off, water splashing out of the poo, freaky crap. No thank you. Im ok with tornadoes, I chase them.

you clearly missed the part where i said i was posting from my cellphone, you dont know when to quit do you???... im done with you.. clearly im trying to drop a retarded argument in which you are extremely sensitive about but you so far up your **** about spelling on the internet that ill be even more stupid than i am now to continue
