Sounds good and you/I can put that in the 5th gen FAQ sticky.

If the VQ30 and VQ35 are the same block, just different bore and stroke, then they mount the same. So that would mean you COULD mount a VQ35 in a 4th gen. Now, then only thing is managing it. The VQ35 has a variable intake manifold (which can be managed with an rpm switch as done with the MEVI. The other thing is the CVTC needs to be connected to the ecu so it releases. I am not sure if the VQ35 has ALL the same harnesses/management devices, such as...MAP/BARO and all the other goodies. Now taking that in consideration, depending on how many 02 sensors and what position they are in on the VQ35 2k2/2k3 we could use the 2k2/2k3 wiring harness and ecu.
On to another note: With a VQ35 in place, then why not bolt in a 6 speed tranny? I am VERY sure Nissan did not change the bolt pattern between the VQ30 and VQ35 that would be a waste. So you could bolt up your 5 speed from a 4th gen if this is the case. The only thing with the 6 speed is the mounting, if the tranny mounts in the same spot then no problem. The axles shouldnt be a problem, using 4th gen or 2k2/2k3 axles. The only other thing I can think of would be the shift linkage, I think the VQ35 is drive by wire, but there has to be a way to get around that.
With all that said, it seems crazy. BUT if you think about all the hondas that go from 1.6 liters to COMPLETELY different 2.2 or 1.8 liters it is VERY possible.

OMG DONALD!!!!
NO ONE'S EVER THOUGHT OF THAT BEFORE!!! You're a genius!! :

see you at the meet
see you at the meetJust dont park next to me too long, or you might get in to your car and notice 5 forward gears, then pop the hood and notice a 3 liter. Then I can come back and post about my conversion

j/p Actually it would be good to look at your tranny and see if it seems to mount the same.
...see you there.

AIM me so we dont kill this informational thread.
[04.08 - 13:29] V 1 Brian: yeah vq30 is a lot smooth then the vq35
[04.08 - 13:29] V 1 Brian: but the vq35 has way more power across the board
[04.08 - 13:29] nsm donald: yeah more discplacement
[04.08 - 13:29] nsm donald: you have a VE35
[04.08 - 13:30] V 1 Brian: haha no
[04.08 - 13:30] nsm donald: they just did away with the VE series
[04.08 - 13:30] nsm donald: and put a Q in there for quiet
[04.08 - 13:30] nsm donald: VQ = Very Quiet
You need to learn how to communicate your thoughts better!

VE did lay the foundation for the VQ series.
Dennis VTCs and VI help the top end so much, I really wish my VQ had the top end my VE does or a VQ30DE-k or VQ35 did.
This looks like quite the mod, I'm very impressed, can't wait to see some applications of it, and hopefully on here. As for the 1700hp in the VQ35, and thinking the VQ43 will take more hp, I think there's some confusion there. What I believe is meant, is the 35 block can handle 1700hp, in that you could put 1700hp into the block and it would be strong enough. The 43 block is still the same basic block, it's just been stroked to add more displacement. That means the hp limit of the block is unchanged, unless you're using a different block that happens to be made stronger. If these stroker kits get more popular, and are even used in racing applications and whatnot, we might see stronger blocks being used, therefore that 1700 rating will increase. But between now and then, I think it's safe to say that the rating is the same.
You people are speaking the same 'misinformation' that this thread is talking about.
The VQ35 is MORE than just a stroked VQ30. The 4.3 block is MORE than just a stroked VQ35.
Read the info folks, it's all been typed up already.

I just started looking in to this "VQ Thing" I am a VE and domestic guy. Could you link me?
thx

With the 4.3 the cylinder walls would be thinner and on the other side of that would be water passages. The VQ is already an alluminum block and a V6. Funny cars are making this much hp and they have 2 more cylinders and another 300-400 cubic inches of discplacement and a BIG blower right on top with LOTS of boost and methane or alcohol injection and sometimes a shot of nitrous and they still blow motors VERY EASY. Now for a alluminum block v6 to crank that much power on paper thin cylinder walls, good luck. hahahahaha
The funny car thing just makes me laugh.

The 4.3 liter AEBS stroker kit comes with forged crank, rods and pistons and a cast iron sleeved block with a closed deck. In laymans term this motor is hard to blow and is stronger than stock. There is little chance of the coolant passages around the cylinders being breached, or the walls of the cylinders themselves cracking under stress or heat. The AEBS sleeves are claimed by the company to be rated up to 55psi. Obviously the rods or pistons will go before then. The 4.3 liter crank looks to be ultra beefier than the stock one too, but that's just going by pictures. I have no trouble believing that a 4.3 liter stroked and turbo charged VQ could do 1000+ hp. 1700 is pretty amazing, I'm guessing that they kept the stock displacement and just reinforced the hell out of the internals and the block. At any rate building a 1700hp VQ is pretty much building a funny car isn't it? =P
As far as the VI / VTC thing goes, most tuners would like to have one aggressive cam profile on which you have some control over the timing rather than a variable one that's hard to adjust via a stock ecu that likes conservative values. Besides it's not like VTEC, we don't have variable LIFT only timing. It would be easier to do head swaps to other VQ motors as well if we didn't have to worry about that. VI's? Who needs one? maybe for a good compromise of daily drivability, but if you just want to go fast? Single plenum intake manifold is the way to go. Take the 350z for example, no VI there. Why do you think they make top end and VQ35's don't?
Oh and another thing, 1700hp motors aren't meant to be daily drivers. Full on race motors get rebuilt every other race and aren't meant to last. They also run a gasoline/methanol or full methanol mix. So really it's not out of the realm of possiblity.
edit: i realized this is import drag, thus i have no idea what kind of regulations they have on fuel. Even so the AEM civic and the Mopar SRT-4 easily pump out more than 1000hp and these are 4 bangers.

Just to clear a few points up throughout this thread...
Funny cars are making close to 4000 HP. Christ, there are Small block Fords pushing the 1700 HP mark on 110 octane. Some of those loonies even drive them on the street!
As far as head bolts go, they are EXTREMELY important. Crappy bolts will eventually stretch, allowing the head to slightly lift off of the deck from the pressure any given cylinder will see. The result? Constantly blown head gaskets, and even blown engines if it's really wound up when the gasket goes.

i am starting to wonder if the VQ30 is a better built engine than the VQ35..
i mean the VQ30 was always built for racing.. but..
the new Skyline will be the VQ30... everyone i see who has done up a 350Z (JUN) has used a VQ30 .. hmm

You can use the VQ35 crank, rods, and pistons, but the block would need to be bored 1.5-2.0 mm since the VQ35 pistons are larger. You should be able to get the claimed 255 horsepower that nissan says. But remember you are in a car that weights less so high 13's should be possiable with a little weight reduction but with a stock motor. Instead of spending $600 on JWT ecu, $200-$300 on y-pipe, $400-$600 on MEVI, and $300-$400 on catback. It would be easier to spend the money on finding a used VQ35 at a junkyard. You can use the stock VQ30 motor mounts if you want to use the VQ35 block. You can use VQ30 heads for higher compression and maybe even VQ30 lower and upper intake manifold to use same fuel injectors.

Hi !
I have some question about swap out internals from the VQ35 and VQ30.
If use the VQ35 crank, rods, and pistons, but the block would need to be bored 1.5-2.0 mm piston size is 95.5mm and how many mm for the stroke ? (81.4mm ??)
if the stroke is 81.4mm ,any possible piston will hit against head cylinder?
what should be careful ?
