Vq power
Vq power
Well hours and hours of google searches and being bored. Since I really don't have money I like to add a little something to the forums. I am learning as much as I can and hope to be as knowledgable as some of the people on this forum.
Anyway I was talking to this guy after I found some racing forum that had some people talking about a VQ engine.

used stock 350Z lower runners, modified a VQ 30 plenum in order to adapt individual throttle bodies.

Stoke stroke and bore because of 3.0 liter class restriction. Makes 400 whp at 8500 rpm.
PBS racing gearbox-5 speed with all straight cut gears-all ratios changeable-spur gears on the tailshaft to change final drive as well.
This is great for people who want to do an N/A buildup. 3.5 liter motors can even benifit more. It seems that you have adjust the powerband from low-end torque to high reving to make good power with the VQ.

I visited AEBS today to see the pro spec series stroker kit (VQ35DE)
I had to see this in person, I talked to the head mechanic Paulus who actually I remember from back in 92 who was a honda guru.
1. The total cost of the kit is 7,800.00
2. Comes with 9325 custom billet steel crank. used in NHRA
a. the crank was very high qulity(see pic) overall stoke is
90mm(stock is 81mm)
b. according to paulus this bad boy should have no problem
with stock rpm revs in fact with rev limited removed the
engine can safely rev to 9k+ with tuning. Even though it is
a 6cylinder his reason is that the prelude and s2000 stroke
are 91 and 90 mm so that shouldnt be a problem.
3. The rods are x beam with internal oil inlet from the crank up
the beam through the wrist pin to squirt into the bottom piston these rods are made by Pauter
4. The pistons are FORGED,you can expect up to 26 lbs of boost for the 8:5:1 compression. no dyno result yet......(wrist pins&rings included)
5. As for the t sleeves thats where Im really impressed with the quality, although they did not have a VQ block there they did have the sleeves very heavy duty, they did have a nsx block with the t sleeves in it. As for blueprint and machine work he expect about 15 hrs labor at 65.00$ an hour. Me and paulus used to use Ed Hale in lakeside ca, he is know for his excellent machine work on race engines. Unfortunately its race season here and 6 cylinders and 4 cylinders are paper weights until the small block chevys are done. Paulus said the VQ block is are stronger then the supra turbo blocks although they are full floating cylinders
But im sure any good reputable machine shop can do this. I thinking to see what Benson Machine shop charges in the Los Angeles CA area?
My final Verdict is this...........Hi quaility, no doubt. Personally I would love to see someone(with money) do a NA build up with the higher compression 11 or 11.5:1 at a price tag or close to 8k without machine work you would be looking at over 10k+ by the time its ready to turn key. I would like to see HP and Torque numbers in the future, Since im married with kids, I will have to pass and maybe settle for the sc or tt and 6-8 psi.
For those with deep pockets, I wouldnt hesitate , the car is still new and im sure we will see many many avenues of horse power, but if you want somthing different ,,,,,,4.3L VQ sounds NICE

WOW, dood. if anything, this would be soo sick. I am all about NA, but at the same time pinching pennies. I would seriously look into to this if
1. my car was paid off
2. the price was HALF
but I definitely like what I see. wasnt there talk of putting 3.5 internals into a 3.0?

pardon my ignorance, but what would consist of the internals swap? of course, this would pertain to an NA application, so what kind of HP could be made over stock(if those numbers have been discovered yet)?
with the 3.5 internals in a 3.0, can aftermarket cams be installed? which camset would be needed for this, 3.5 or 3.0?
this is all theoretical, of course ;-)

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.

I think it would be more beneficial to use the VQ35 intake manifold since it is variable already and they live on the top end. So a VQ35 will bolt into the sport of a VQ30 in a 4th gen? I guess the only problem after that would be getting everything set up so there is no check engine light.
Boosted VQ35 in a 4th gen would be good.

The 350z has better top end because of better intake manifold and maybe exhuast. It is ecu tuning also.
Some 350s are making 280 whp with headers, hi-flow cats, catback, intake, pulley, and cams.

would the boring 1.5-2.0 be a little excessive for the block to handle? on that same note, how much can a block(typically, and 3.0 in this case) be bored over before it starts to lose its integrity/or does more bad than good?
my next question is, the exhaust manifolds(headers in some cases) attach to the block of the engine, correct? that way, with the internals from a 3.5, the exhaust wouldn't be affected as far as replacing them with a 3.5 exhaust?
pardon the naive questions, but this sounds very interesting. I do like the idea of doing this, instead of relying on aftermarket bolt ons and such, or shall I say, before adding aftermarket bolt ons. I am pretty sure this would be a while until anyone actually does this and has documentation of improvement, but nonetheless, this is veddy intedesting.

ok. does the cylinder head = the block of the engine?
thinking out loud, could the 3.5 exhaust manifold fit on the cylinder head of a 3.0 without modification? if so, would there be a performance gain?

IF a VQ35 can hold 1700hp, what in the HELL do you think an AEBS VQ43 is going to do?
It's going to get VEEEEEEEEERY interesting. I'm going to start watching for these guys on SpeedVision.

This is starting to enforce my predictions that the 350Z will be the next Supra.

would there be a performance gain using the 3.5 exhaust manifolds or aftermarket headers for the 3.5 on a 3.0?
are the exhaust manis larger on the 3.5 vs. 3.0?
isnt there such a thing as boring the block over too much?

That may be the same guy who mentioned that on my350z.com.
It's probably true but I just want to hear it from another source.
Here is something I have been thinking about. Of course my thinking gets to a certain point, since I do not have the money to R&D it right now.
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.

Add drive by wire throttle-body.
1)A VQ30DE-K has been put in a 4th gen..
2)A VQ35DE has been put in a 2000 5th gen.
3)IIRC, Jeff or whoever from NY put a 6spd in a 4th gen.
4)The VQ35 Altima has a 5spd tranny, so I'd say the 4th gen tranny could easily bolt up.
maxS already put a VQ35 w/6spd in a 2000, a VQ30DEK in his brothers 4th gen, and he's hinted that he may be putting the VQ35 from the 2000 into his brothers 4th gen..
Just a matter of time/$$$ in my opinion.
