I am looking to do a manual swap into my auto 2000 max and I have been wondering if the 6 spd from the 2002-2003 5.5 gen max's will bolt onto the vq30de I have now?

Any help you can offer or info you can give will be greatly appreciated!! I am also apologizing right now if this covers an area that has alrady discussed.

Thanks in advance!!!

don't think so

 

Tilley will be doing my 6 speed swap on my 02 Auto, the swap for you wont be impossible ,but somewhat diffcult .

 

No it won't bolt on. You can make it work but it's not really worth the effort in most people's opinion. There won't be any performance gains from the gear ratios if that's what you were thinking.

...it will work but there are different mounting points...blackbirdvq did one to a gold 00 max...now if its worth it that another issue...

 

Yes Black Bird do do a 6 speed swap on VQ30, According to Tilley its not that diffuclt except the mounts on the VQ30 are welded,so therefore they need to be cut and new ones will need to be fabricated on, but on the VQ35 they arent welded...

 

Tilley has a 6 speed on his turbo 99, but I don't know what he did to install it. There was also another person with the 6 speed in a 4th gen., so it is possible, but performance gains would be tiny. Tilley says it at least feels smoother than our 5 speed trannies....

 

Jeff from Maximum Tuning put in a 02 6-speed into his 4th gen, but from what i remember he used the 5-speed bell-housing and he had to grind the insides to make the 6-speed gears fit and clear everything. i think he used a 4th gen lightened flywheel with a 5th gen clutch (not sure, it was a long while ago)

the 5-speed and 6-speed bell housings have different bolt patterns

he also remarked that it won't do anything for your 1/4 unless you are making serious hp (i.e. turbo)

 

there is no way too use a 5spd bell housing on a 6 spd. You have too use a 6spd flywheel or a custom made 5 spd cause the starter wont catch the teeth on a 5 spd and the throwout bearing is so far from the PP that it wont disengage.

 

i gave that info out on the mounts. the 5 speed mount is welded to the frame and the 6 speed mount is bolted to the frame. plus the linkages are different on the 5 speed ad the 6 speed. ad all those guys that say that 5 speed is faster, i say that the gains are minimal and you wont even feel it on your butt dyno either.

 

5-speed has less drivetrain loss and is lighter.

 

and again the difference is very minimal between the 2 trans

 

Depends of your definition. I heard the 5-speed has 5 sets of meshing gears while the 6-speed has 8 (different and two reverse setups or something like that), and in addition to that you have the 5-speed's 18-pound flywheel versus the 32-pound 6-speed flywheel so that is certainly worth a few ponies.

Both 6-speed Maximas and 5-speed Altimas put down pretty much the same numbers (although the Altima's torque seems to be higher - I've seen as high as 227wtq stock) despite the Altima being rated at a lower HP. The 2nd overdrive gear is nice for gas, but with your 17's and more rotational mass we're probably both getting the same gas mileage (sometimes in the high 400's to a highway tank).

 

I think the 6spd is alot stronger then a 5 also its a hell of alot easier too shift, hell in my 6spd i can shift so fast you would swear its auto, but in the 5 spd it has a notchy feel and getting 3rd gear isnt always the easiest while racing.

 

If anything, more rotational mass equals better cruising gas mileage due to more angular momentum. In other words, it takes more torque to accelerate it, but less torque to maintain a certain speed.

 

Well unless I'm wrong 6-speeds don't seem to really be getting much better gas mileage than 5-speed Altimas. I know I'm not compaining.

 

I was referring to the heavier wheel/tire combo thing.

 

Makes sense.

 

It seems that mod for mod, the 5spd altimas put down more hp and tq on the dyno than the 6spd maximas. I'll keep my 5spd until it dies, then put in a 6spd.

 

What clutch options are their for the 6spd? Anything that will hold 650ftlbs? Anything at all?

 

The better gas mileage would probably only come from highway type cruising at low rpms in 6th gear.... the other gear ratios are relatively close so I'd think that for local/city driving, it wouldn't really make too much of a difference.

EDIT: Btw, I was comparing the 5th Gen 5 speed with the 5.5 Gen 6 speed ratios.

 

Ratios (for what it's worth):

5-speed:
1st=3.28
2nd=1.85
3rd=1.27
4th=0.95
5th=0.79

6-speed
1st=3.15
2nd=1.94
3rd=1.39
4th=1.05
5th=0.80
6th=0.63

Yeah the ratios are better. Less aggressive 1st gear for better traction, closer 2-3-4, and one extra overdrive. Ideally I'd take the 6-speed first gear and replace our overly short 5th gear with the 6-speed's .63 (or .67 in the Spec V). We can't do that, but there is a longer .74 5th gear available for 5-speeds.

 

I weighed the 6 speed dual mass flywheel at 32 pounds.

 

Virtually any 350Z clutch that you can find. But, obviously you'll need to avoid those that need specific flywheels since you're using a A32 ECU.

 

Got some links/proof?

Because I haven't seen anything to suggest that. They don't seem to have people over there who insist on the specific dyno conditions that we do.

(DJ 248c, SAE correction, 4th gear, etc.)

 

Holy crap! The 5-speed weights 18. Almost double. What about the tranny itself? Do we know how much heavier it is than the 5-speed? 5-speed weights in at 107 pounds I believe.

 

What other parts are needed for a 6 speed swap from an Auto

 

That's enough to shun me from ever going near that setup.

Didn't someone use 350z parts w/ a 6spd and get amazing gains?

 

The person you quoted did it.

 

By any chance, would it be possible to put a 6sp in a VE5?

 

With enough $$ anything's possible.

Feasible, probably not.
