so, what about it...longer stroke, anyone else know any details?...get a discussion going...brainstorn....VQ40dett?.....in a max?

 

BTW it's the new VQ in the new pathfinder...270hp, 290 torque good start..

 

block height is supposedly different but I may just try it once i can get a hold of one. BTW probably wont clear the hood.

 

interesting

 

This discussion was started months ago I believe.

 

screw the hood, cut it muscle car style or build cf or fibr gls....use L/C slugs and bolt a GT 3540 and A fmic, Quafe it, stand alone FMU, ....Dir Port N20.....nasty...

 

so....any results of the brainstorming?

 

maybe in '06 or '07 we'll see a VQ40 in a Max

 

Stroke will probaby be poor for high rpm.

 

if I'm not mistaken, the 3.5 slugs are the lightest production on the market, same as in the VQ40 I would assume so hopefully with some knife edging of the crank and some tighter springs and retainers, you could spin to 7.5k safely, boosted with the stand alone ECU and a seriously ported 3.5 head, or at least the cams, and sodium filled stainless oversized valves....maybe we'll see this conversion done in the R35 skyline if it goes to the VQ35DETT set-up....

 

just do a 3.5 like i did i gained so much lowend torque.

 

difficulty rating, cost, clearance problems....6-spd possible? deatail always appreciated...thx

 

maybe they'll even design it for more high end and crack the 300 hp and toque threshold...

I was all about wanting to do this swap untill I got more details of it.

The VQ40 is a taller block and won't easily fit in the Maxima anyways.

I wish we could ban any future references to that thing.

@ $7800 NO Maxima owner would ever buy it.

 

reminds me of the $9000 VG motor that can be purchased

 

wow 40dett

 

Exactly, there's no point in spending that much just to have a larger Maxima engine...put that sort of thing to better use on a Z/G35.

I don't think a VQ40 in a Maxima is possible or truly worth it, for a lot of reasons. For one, it obviously won't clear the hood and I think it'll be by more than just an inch or two. I think it would look incredibly stupid to be driving around in a "sporty sedan" with something big sticking out of your hood. I already hate hoods on Maxima's with any kind of bulge or scoop to them. Secondly, the raised displacement is entirely in the stroke, and as someone has already mentioned, that large of an increase in stroke is going to hurt revving capabilities.

But...at the same time, the stroke is still smaller than the bore. If the stroke were a lot more than the bore it would be one thing, but it's still smaller. So who knows how well it's going to operate. Surely Nissan wouldn't use it if it were terribly bad.

 

thanks for the link and details

 

let's make it happen....start looking for specs on the VQ40's deck height, internals, etc..

 

I'm amazed, b/c when the 1st VQ35DE came out about 3 or 4 years ago, it was used exclusively for Pathfinder. Look how widespread the VQ35 has become since its debut. About my post stating there could be a VQ40 in a future Max and after reading everyone else's view, the VQ35DE in the '06 or '07 Max somehow will get a huge power boost and retain its 3.5L design or it will be stroked to a VQ38DE

but this is years from now, though

 

Deck Height: The distance from the top of the piston to the top of the block deck.

Block Height: The distance from the crankshaft centerline to the top of the block deck. <~~ This is the only one we're concerned with because Nissan engines typically have a Zero deck height.

I search for this data a few times a week and was actually the first to provide the bore & stroke info. Once Nissan finally releases the Service manuals I will post more of the data. But right now there simply isn't anything else publicly known about it.

 

I was thinking, VQ40DE (possibly lowering motor mounts) knife edging crank with '04 6-spd, TB from VK56DE (if compatibleVQ35 ported and match honed heads, with aftermarket cams, (ground for mid-range tohigh rpm power), new springs and retainers, MEVI or VI from gen 5 or 5.5, Quaifed diff, and maybe a bolt on S/C or turbo manifold with an upgraded Garret GT3540, 4" custom cat back, and a stand alone to deal with ECU compatibility...hood will be easy to modify if necessary....would look really nice with custom wide-body kit holding some 275/35ZR18 Volk GT7s....or if the stand alone is too expensive and you're going all-motor, you could just get a reflashed JWT ECU, to allow it to spin to 7500 or higher...with tuning, trial and error, I'm thinking 335 crank HP all motor is possible with over torque easily over 300..550 plus blown....600 plus with a huffer and some giggle gas....just hoping....may try and do it myself...just trying to work out the feasiblity...thanks again for the input

 

wow, i wanna talk just like u guys one day....
one day....

 

you either have a great sense of humor...paid us a great compliment, or are a total...hopefully it was one of the former

 

This would be a huge waste of money a 350z with rods pistons and valvetrain work with the 3.5 with a twin turbo kit .
It runs 8.3 @ 176 in the 1/4 with street tires and with the stock open deck has 1000+ rwhp .
If you were looking for it built for na id say good but for speed the 3.5 with a few thousand in work will be stronger than a sh$t brick house.

 

that's why, plus it's original....VQ40DET or VQ40DES is unheard of, especially in a FWD 4th Gen max...but good point....so let's do it in a G35...I mean G20

 

Anyone found any more definitive info about the engine, aside from output and the models in which it will be offered...?
