I was just thinking...taking Desert Pearl's methods into consideration...just wait until some dumbass totals his 2003 maxima se'r...and pay like half for his crank and rods to increase displacement in our cars!

does anyone have a hunch on how they're making the extra .5? if it is the crank for displacement this would work right?

then i would add a 150 shot nitrous and a supercharger

 

yea but then, u have to install.... thats a pain to me.. ur not very nice to people who crash huh!?? haha j/p

Stroking the engine is not the right way to get the power. You have to bore it out some.

Go take a look at google for engine design pages, you will see, bore is the way to go.

 

speaking of boring... i once saw a Brabus MBZ go from a 3.5 to a 4.9 liter engine! wouldn't you be afraid that to a certain point the engine wouldn't be able to take all that pressure? ich weiss nicht....

not as bad as a mercedes 3.5 bored to 6.2!

 

damnnnnnn 3.5 to 6.2..

 

hmm...maybe we can do an engine swap from a 3.5 max, then bore it to 6.2L to show that we mean business...

 

You would also need an ECU to go along with the extra .5 litres of displacement.

 

That is the tradeoff when you get an aluminium block. It weighs less, something like 100 pounds less, but the tolerances do not permit much boost.

The 280HP skyline with a steel block can (and does) some 600-700-800HP). The Sentra's block can do 600 HP.

 

You cant really just replace the crank and become the 3.5l engine. You have to bore the engine out thats only if nissan did not use a bigger block all togther. For instance the contour guys can bumb there 2.5l engine to 3.0 but they have throw in the block from a tuaras which is 3.0. So I'm pretty sure it would be easier to do and engin swap.

 

Yep, probably easier to do a swap. The 3.5L in the Altima still confuses me-- I wonder what that means to the 3.0L of the current Maxima's VQ??????????????

 

And they got the skinny on the displacement increase straight from Nissan. It came from a stroker crank and shorter connecting rods. There is a difference in the cylinder bores, but it is very negligible.
If Nissan was going to bore the VQ out to 3.5L, they would have to take the raw, unbored VQ block and bore it out with a larger dimension in mind. They'd also have to add bigger pistons too. This is because you can't bore out aluminum block engine very far beyond the initial stock bore.
That's why you're seeing Hondas(mostly the B16/18s) getting stroke jobs done. If you combine the stroking work(Crower offers a 2L kit for the B-series engines) and a tiny bit of boring(I personally haven't read about more than .20 over), a B-series engine can almost match a Prelude's H22A in displacement with a lot less weight.

 

That won't work. You will end up w/ some really high compression ratios. The best way would just to swap the whole 3.5 engine(if it will actually phyically fit) I bet it's a little taller. ie. block height is taller to accomodate the longer stroke length.

 

Isn't this 3.5 liter going into the 5th Gen body style?
It's got to fit somehow.

 

Anyone have the specs on the 3.5? I'll see if my shop manual has the 3.0 specs.

 

Look at the specs for the Pathfinder. It's the same engine just better breathed and exhausted.

the only question left is, is the 6sp going to make it and what the ratios are going to be.

 

For those who are interested......a pic of the 3.5 from the NY Auto Show

 

Thanks Haulin. I think my eyes are getting a little misty. It's just beautiful.


I can't wait!

 

Stay tuned for more upcoming pics from the Nissan booth @ the show! I will be posting them soon!

 

Im assuming the VQ35 will also be an aluminum block??...this will also mean that it will have the same limits as the VQ30 in terms of boost correct?

ie. currently the VQ30 has an approx. limit of 400 hp...
since the vq35 would still be an aluminum block the limit would still be 400 hp right? or maybe even less since it has been bored?? could increased compression from boost be more of a problem for the 3.5?

hogan...isnt the intake man. on the 5th gens plastic?

 

it's some sort of special plastic resin....I think BMW is also using it in their engines now....

 

Damn good lookin' engine, is that a precat right on the header? that would be a pain in the *** to get rid of right? Anyway I would highly be in favor of an engine swap but you would have to do the tranny swap too from a 5 speed to the new 6 speed!!!!!!! God that new max is going to be really sweet. Don't flame me or anything guys but I would rather do an engine swap to my 97 just because in my personal opinion I like the look of the 4th gen the best, the 5th gen second. and correct me if I am wrong but Nissan is putting that engine in the 5th gen body first before they go to the 6th gen, I guess we will have to call that the 5 1/2 gen Anyway just a thought.

 

Take some pics of your engine, Hogan. I'd like to see it.

 

I can give it a try tonight after work...I am decent with photoshop.....just drop them in my e-mail and I will try and post them tonight....

 

Maybe Psing23 and Maxima97GLE can have a sketch artist draw it from memory?

 

Post the pic up and let us take a stab at it, Hogan.

 

cryogenics? this sounds expensive....
