Has anyone investigated this option seriously? It seems that there are more similarities between the VQ30 and VQ35 than were originally assumed ... has anyone validated whether the 6MT 5.5 gen tranny would mate to the VQ30? If the VQ30DE-K tranny works in a 4th gen, why not the 5.5 gen 6MT?

 

yes it's been talked about quite much & NO you cannot make it work .. or at least no one has done it yet... i guess with a great amount of money it can be done... would it be worth it? NO

 

I forgot to mention, I'm not interested in just hearing "no". I'd like maybe a link to a thread with technical content as to why or maybe some first hand info from someone who has attempted, measured, lined up or otherwise did some formal investigation.

I am also very well aware that anything can be accomplished with enough money ...

 

I'm not really sure why you would want to do this.

 

well then...you have 48 pages of threads in the 4th gen forum . . . Have Fun...
I guarantee you, that you will find your info.

 

In the event one would need a new transmission, being that 4th gen trannies have been proven time and time again to be mostly junk, it would be nice to have the option of a 6MT tranny that, even in stock form, was made to handle almost 70+ more HP than a 4th gen tranny. Additionally, after driving a 2002 6MT, I was impressed by the transmission and liked it very much.

 

Very helpful, thanks.

 

i think someone did this, it was highly complicated from what i heard.

 

no problem.

 

all right...
here...hope this helps...

I thought someone at maximum tuning did it.

 

someone has done it

 

I could be way out in left field on this, but here goes:

Tilley swapped a 3.5 bottom-end into his 4th gen, correct?

Wouldn't a 6-spd be somewhat easy to install on on that 3.5 block?

Kind of a kill 2 birds type of deal.

 

well...if someone has done it thenthat's news to me... but i think you guys are thinking about the dude that put the 3.5 in the 4th gen with a 6 spd.

 

haha...you beat me by about 10 seconds

 

Harrrrrrrrrrrrrrr!

 

Now, THAT was helpful. Thank you.

Looks like it can be done, for a high cost and with little gain. Surprising no one has made a beefier tranny for our cars yet ...

Swapping a 3.5L into my car may become a project in the next 24 months as soon as I again comtemplate buying a new car. I'll wait for a few others to do it and see how results come out.

 

www.cardomain.com/ID/BlackBirdVQ check out the site on one of the pages there is a 00 Maxima automatic that I converted into a 6spd. Due to other circumstances the car left my shop after weeks and weeks of waiting for parts - undrivable. All it needed was a fuel pump. Yes its doable, would I wanna 6spd in my 5spd ? No.

 

Odd. I assume Tilley is using his old 3.0 5sp mated to the 3.5 block. I don't quite understand why it wouldn't go the other way. Maxxum tuning's reference indicates there was cutting etc.. but no real info. I guess the case is larger.

Another odd thing is everyone assumes that the 6sp MUST be better for acceleration. But there's no comparision on the gear ratios/final drive ratio. Nor is there a discussion regarding the main and outshaft diameters for strength.

 

Just keeping the old 5spd is easier to do. The gear ratios have all been posted IIRC and the input shafts are the same on some of them. However I did a clutch in a '96 5 speed that had smaller spline.
