Damn straight!!! when you can tune an RB26 motor to pump 1015hp at all 4 wheels like veilside have done with their R34 drag car, you know that the RB26 has hell potential. I have seen footage of other RB26 motors with plenty of hp to spare and capable of running well over 300Km/ph and they r street legal.

NEVER No engine will look at how much they cramed into the veilsides r34 dragger.

There is an aftermarket kit from AEBS that will allow VQ's to make 1500hp+ 'without much trouble,' according to their engineers. You can bet the VQ will be making far more torque, as well.

There are street driven Maximas with VQ30DEs that have had turbo kits added. On a stock block and a not-so boost friendly compression ratio of 10:1, they have been making over 500hp. It's just boost and fuel. No internals, cams, head porting, etc. With a buildup, who knows how far they could go.

Is the new vq engine really that durable enough to handle 1500. I still think a flat six works the best as far as compression goes I mean look @ the dauer 962 same type of lay out as the rb.

Flat six != Straight six. :uhoh:

A boxer, flat, or horizonally opposed engine is completely different from an inline engine.

An inline six is just that. A six cylinder with the bores lined up single file as one bank. The piston motion is roughly straight up-straight down.

A flat six like the Dauer's and other Porsches has two cylinder banks like a V6, but its cylinders are 180 degrees apart. Some smart alecks refer to a flat six as a "180-degree V6." The piston motion is pretty much left-right. This leads to the nickname 'boxer,' since the motion of the pistons and connecting rods resemble a boxer's punches.

What does the cylinder layout have to do with compression, anyway? :eek7:

Is the new vq engine really that durable enough to handle 1500.
The sleeves built by AEBS are capable of handling 55psi. I don't see why not. Especially since the sleeve kit includes a stroker kit that brings the VQ35DE up to a full 4.3L. All for a bit over $8k, btw. ;) On an RB, just 3L is pushing your luck.

Nvm I was thinkn about go kart engine I dont know y I was thinkn about if they were completely slanted why wont then engine get flooded isnt it a 4 stroke?

Why would the engine get flooded? As long as the proper amount of fuel is used(not too rich, not too lean) the engine won't be flooded.

If you turn a 4 stroke upside down or side ways it will flood it has a fuel slinger.

i not a fan of any VQ engine, I still preffer the RB engine over any VQ engine!

Haven't heard any problems like that. Even this dictionary says that 4-stroke flat motors run just fine.

You might eat those words in 2007. ;)

Damn I wonder how the hell the oil stays contained.

I don't know. If it was a problem, it was probably solved long ago. After all, boxer engines have been around for decades.

You might eat those words in 2007. ;)
no i wont, just the sound of a high reving rb26dett says it all, and I assure you there is no skyline like the 32 and 34 and never will be, specially if a VQ engine is going to be used. So what if it has 450 hp or more and what not, but the VQ engine is not GTR Descendant.

Four pages later, and you still don't know what the car will be like yet. :lol: Who are you to pass judgment?

The RB isn't related to the S20. Technically, it isn't a GT-R descendant, either. :p

This is from the ROAD & TRACK MAG.
Lotus is once again in the U.S. sports-car limelight thanks to the introduction of the Elise. What's next for this small car company bade in Hethel, England? The Esprit replacement? Yes, but before that, we discovered that the company is busy with the upcoming Nissan supercar, the GT-R. Sources told us told us that Lotus has been hired to fine-tune the car's handling, which includes developing the suspension and steering. The prototype car, which wears an Infinity G35 Coupe shell, has been spotted numerous times around Hethel this past year.

Nissan also has outsourced the development of the GT-R's engine to Cosworth, the noted race-engine builder. We hear Cosworth is massaging Nissan's VQ powerplant to produce about 450 bhp. Early reports suggest that the 6-cylinder engine will be turbocharged.

So what do we make of all this? Well, it confirms that Nissan is serious about the next GT-R, due to hit showrooms around the world in 2007, and is seeking the help of outside experts to produce what may be the ultimate Gran Tourer. When the next GT-R, which may possibly wear an Infiniti badge, arrives, drivers of cars such as the BMW M5 had better keep an eye out. -Sam Mitani

s20 OLD ASS HELL SKYLINES
RB26 SKYLINES AND 4WD-GT-R'S

This is from the ROAD & TRACK MAG.
Still doesn't amount to a hill of beans until the production model comes out. We went over this on the first page.

s20 OLD ASS HELL SKYLINES
This includes the original GT-R, which is actually considered to be the greatest by some, rather than the more recent models.

If you just admit that you're set in your ways and aren't open to any other choices, I'll leave you alone. :p

i meant the 4wd GTR's not the first GTR, started with the RB26DETT.
I have nothing against the VQ powerplant but i think that the GTR should keep an I-6 not a V6, that is all. Sorry to get you all defensive :evillol: but i think many real skyline fans think the same way as i do.

IF THEY DO STICK A VQ IN THE SKYLINE AND IT TURNS OUT TO BE A 350Z WITH WIDE BODY AND A GTR EMBLEM, IM GOING TO SHOOT MYSELF! :angryfire

:banghead: so the US will never see the Rb26dett unless we import a skyline....................sucks!

Theres always a chance though in this case a very little one...

or we do an engine swap :naughty: I saw a 300zx with and rb in it.

Well, I'm sure they are going to use the VQ engine, with a G35 body. By 2007 the G35 might be a little changed, but maybe it will still have the suspension and chassis of the 350Z. Anyways I rather them use the RB, because of the crazy power it can make, like the 2JZ. But like I said, I think its unlikly. My showoff spoiled ricer causin has G35, and if the GTR comes out in 07 as an Infinity he could trade it in. I wouldnt want to see a GTR with Lambo style doors and 20s, would you (that is what he want to do with his G35). I think there are too many ricers in the US, which is why part of me is glad the RB wont be back.

I understand what you mean EvoCrazy, if Japan were to bring over one of its most legendary cars and engine then what happened to the Accord, the staple rice car, will happen to the Skyline.

Very true. Its already happend to the Supra, and RX7. Those cars dont get HALF the hype of the Skyline, so you can imagine. But then again, a lot of ricers dont know that the G35 is a Skyline. My ricer causin knows, but he thinks its just as good as the R32-R34 GTRs. Hes fucken stupid, and I hope people like that dont get there hands on one.

... a lot of ricers dont know that the G35 is a Skyline.
No....a lot of ricers think the G35 is a Skyline. If it WAS it would be CALLED a Skyline. A Skyline is RHD. An Infiniti is LHD.

Yea, but in Japan the G35 is called the Skyline. So, my ricer causin goes bragging he has one, then one day I pointed out how its NOTHING like the older GTRs. I pointed out the fact that it didnt have the RB26, suspension, ATTESA ETS, or anything like the older ones. But hes a fucken retard. The thing is, ricers dont know the difference between Skylines and Skyline GTRs, so thats what hes maken his out ot be. But, yea, the G35 is a Skyline, even though it doesnt look like the older ones.

Stop worrying about ricers buying "R35" GT-Rs. It's not as if the car will be cheap. It could be as much as $70k, well out of the reach of the average ricer.

There won't be that many produced, either. Think about how this is a halo car. Production, or at least the US allotment of it, would probably be similar to that of a Viper or something. Just as an example, Britain only got 50 GT-Rs back in 2000.

That would be good if its expensive and cheap. That should keep it out of the reach of some ricers, but my causin is RICH. If its rare that would be good, because thats even a less possibility that a ricer would get one. Kinda like how the Evo MR is going to be very limited here.

That would be good if its expensive and cheap.

Expensive and cheap? Which do you want? :lol:

I don't get the point expensive and cheap ?

Sorry LOL. I meant "expensive and rare" Get it now?

With all the speculations and dribble being posted in this thread, I thought I would let it go for a while before I posted something.

Officially "off the record" the "GTR" has been pushed forward for release, at least to the JDM market, then was put on hold if that makes sense. I understand but sort of hard to put in english translations and I can't be assed typing out a dictionary description.

The main reason for this is "engine" reliability. As many of you are are aware of or have spectulated the engine combinations of choice are the VQ35DETT for the JDM, and 4.5 L V8 infinity in N/A form for the US market. One thing Nissan won't do is release a car with a new engine configuration without knowing for sure the motor can stand up to the horrids of daily driving even with mild bolt on modifications. The VQ was tested for two years now in the JGTC in the R34 GTR body and last year won the championship. However that was not without problems. Something the RB never gave them. There are other contibuting factors that were not explained very well to me but Nissan is being quite quiet about the whole thing with good reason. The next GTR has one hell of a reputation to live up to and with all the hype a dog could sink it in a matter of months. Something I'm sure Nissan won't want to happen when you have invested a few hundred million in R&D into a car.

As far as the body shape, badging, and exact name that hasn't been released publicly yet. IE; let the speculations continue.

I've gotten this information directly from a source who frequents Japan every month. Rumors are fun and it certainly brings out the spite in everyone. Just don't take it so seriously though. When it happens it happens.

Thanx Razor. Hopefully it will live up to the hype and its name.

i still say, nissan would be better of with an RB but it is their choice and no mine so what can we do?

I dont really think we can do anything about it. If they do they do, if they dont at least we know they will make it powerful like the RB.

ok, the vq series is good, not amazing but good, the rb series is much better specifically sesigned with racing in mind, the rb can be taken to 3.2 liters fine, with a slgiht block switch to the aussie 3.0 sohc rb, 3.0l block + gtr head + stroker kit + stock gtr turbos gives a reliable 500hp 500tq, now jsut upgrade whta you want


to answer what was said earlier, sure you can bolt on a turbo add some fuel and your vq can run 500hp with 10:1 compression no problem...however it then becomes a question of how long your engien is going to last, ide put money on maybe a year.


as to how much power you can get out of an rb vq or anything, its ALLLLLL a matter of how much you want to spend. i can show you 2.5l v8s with 1600 hp, i can show you 18wheeler big rigs that run 0-60 faste than a porsche turbo and can hit 230mph, again its all a matter of money but its also how reliable you want.


anyone want to argue hit me up on aim, its the same as my AF name

yes that is true but if we make a survey many will say that nissan should keep the RB

I think the RB would be nicer....but not for the US. Too many ignorent bastards here, and I dont think they deserve it. Then again the RB would be a good thing. Oh, and about the RB VS VQ. Everyone knows the RB is WAY easier to mod than the VQ. Even though I understand what your sayen, I say bang per buck, the RB is better.

ok, the vq series is good, not amazing but good, the rb series is much better specifically sesigned with racing in mind, the rb can be taken to 3.2 liters fine, with a slgiht block switch to the aussie 3.0 sohc rb, 3.0l block + gtr head + stroker kit + stock gtr turbos gives a reliable 500hp 500tq, now jsut upgrade whta you want

So what is it that meaks the RB so much better? The VQ was designed for racing too.

The Maximas with 500hp, 10:1, turbocharged VQ30DEs have been around since 2002 or so. I haven't heard of any of them getting a rebuild. If you want a safer combination, or want more boost, you could always get the 9:1 pistons from the JP-spec VQ30DET. That'll be cheaper than the RB combo you mentioned, which also involves giving the RB an advantage in displacement.

The VQ wouldn't really need to make as much power as the RB, anyway. Given otherwise equal cars, the VQ-equipped car will be lighter by ~200lbs because of the engine differences. That car could afford to have less power and still keep up with the RB-equipped car. The better handling/weight balance(shorter engine) of the VQ-equipped car is another advantage.

just give it some time. the thousands and thousands of aftermarket parts for the RB26DETT didn't become available overnight. One of the main reasons the RB26 is so loved is because of the options you have to work with. I've seen thousand page catalogs issued by many manufacturers with just parts for RB motors. you walk into a stark or an autobacs and you can get anything you want. This is not so for the VQ. I think it will just take some time. my 2 cents. but do you see what I'm saying? people love the engine because it's great to work with. i think most of that is attributed to the options you have. the options do not exist (to that extent) on the VQ, therefore I feel that is it's major shortcoming right now.

ok ok, fine, yes you can do anything, fuck the fact that the US does or doenst deserve the RB, we SHOULD get it, for ppl like me

as to the v6 vs I6 argument, teh v6 will ALWAYS be inferior! go talk to any engineer, the v6 and v10 are out of balance and need a great deal of counter balancing to get them to work right, sure argue that f1 uses v10s and every other car in the world coems iwth a v6, but its because of compromise, not becuase they are better, more tq than an i4 and better gass milage than v8, though every car manufactuerer wishes they coudl sue nothign but i4 and v8s or v12, thus the rb is sitll a better engine, and if the vq was i soo good, then why did up until recently they use the rb for racing, and they still use it as engine of choice for drag, only jgtc uses the vq, but then agian they have n/a v8 supras too so jgtc is complete shit now for the 500 class

but in the end, it doenst matter cause its all abuot love of cars, no matter if u have a fiesta with a 1.8 mazda turbo in it or any civic or a 1300hp supra form www.suprastore.com, as long as u love what you got and rep it


oh yeah and as to dropping your compression to 9:1, still no low enough, there is a reason cars(as in ppl who actually race) and what any longevity out of their engine run 7:1-8:1 and yes each point maters that much, my blown hemis runs 7:1 and im runing 10lbs of boost and i push a good 700hp :)


much love to cars

I love cars to, and I love the Zs. Lets face it, Nissan is known for the Z carz, not the Skyline as ricers think (as you can tell I REALLY HATE ricers). They are both good engines, and whatever they choose, they choose. I understand why you oouls want the RB, becuase well, enthusiests like us deserve it, even if Criag Leiberman will kill one. I do understand your point though.

A few words of advice to an AF noob.

- Watch the cussing.
- If you are the kind of person that is prone to typing errors or have poor grammar, type slower and collect your thoughts first. I had to re-read your post 3 times before I got the idea of what you were trying to say.
- Learn the difference between fact and opinion. Facts are the things that you can argue about, opinions should be expressed then left alone.
- If you ARE going to argue a fact, be sure you are correct before you start ranting ok? Nobody will hold it against you if your wrong, but, if you're wrong and being a schmuck about it, you just lost all credibility forever around here.

Just follow these simple guidlines around here and we'll all get along fine ok?

And FYI, I am an engineer (well used to be anyway), V-engines are just as unbalanced as Inline engines. The only difference being that the power-stroke force is divided between 2-axis in V-engines rather than 1-axis in an inline engine. If you would like me to explain the dynamics of converting 2 axis of linear motion into one axis of polar rotation, I will do so but not here for everyone's sanity ok? Also, the reason that V-engines are used so much is mainly due to on reason... size. Have you ever compared a V-8 next to an Inline-8? Whew! That would be a huge hood!
Oh! And JGTC is using the VG35 in the 350z right now. Here's why. JGTC rules state that cars can only be raced with the engines, and many other equipment that they came with from the factory. That means no swaps. The Nissan Skyline GT-R was built for those races from the beginning, it came with the RB26, old news. Now Nissan is running the 350z (and still winning BTW) and since that car came with the VG35, guess what motor they are using? Yup, the VG35.
And stop trying to guess what these engineers are thinking... you aren't them. Odds are they are even much better educated than most of us and might even have some insights that you don't.

Welcome to the AF Skyline forums!

THAT is ONE LONG SENTENCE!!!

ok ok, fine, yes you can do anything, fuck the fact that the US does or doenst deserve the RB, we SHOULD get it, for ppl like me
So, uh, what exactly was the reason Nissan should retool their factories and restart building an engine that doesn't meet anyone's emissions standards? Just because you want it? Right. :uhoh:

as to the v6 vs I6 argument, teh v6 will ALWAYS be inferior! go talk to any engineer, the v6 and v10 are out of balance and need a great deal of counter balancing to get them to work right,
Don't generalize so much. As technology improves, the advantages of an inline will become even less apparent.

thus the rb is sitll a better engine, and if the vq was i soo good, then why did up until recently they use the rb for racing
Nissan was using the RB because it had been in production for almost twenty years. The VQ's been around for less than half that. :rolleyes: The VQ was also introduced at an inopportune time between GT-R development cycles. It was released in 1995, the same year as the R33 GT-R, which had probably been in development for a while. Schedules probably just didn't mesh. Here's a better question: Why do you think Nissan switched?

only jgtc uses the vq
Bzzzt! Wrong. Click. (http://www.nissan-dakar.com/EN/SPECIAL/RACING_VQ/index.html)

but then agian they have n/a v8 supras too so jgtc is complete shit now for the 500 class
Why do you think Toyota switched from the 3SGTE I4 to the 1UZFE V8? Hint: it's similar to why Nissan switched, and may have actually been in response to Nissan's change.

oh yeah and as to dropping your compression to 9:1, still no low enough, there is a reason cars(as in ppl who actually race) and what any longevity out of their engine run 7:1-8:1 and yes each point maters that much, my blown hemis runs 7:1 and im runing 10lbs of boost and i push a good 700hp :)
You sure about only running 7:1? If you're only running 10psi, you should be able to have a higher ratio, at least 8.x:1. That will improve response, at least on a turbo setup. I haven't heard of any Evos or GT-Rs running less than 8.5:1, sometimes 8.8:1, and they do just fine.

- If you ARE going to argue a fact, be sure you are correct before you start ranting ok? .......

Following your own advise, you need to check out the JGTC info. JGTC rules allow for any engine change provided the car and the engine are made by the same manufacture. So, any Nissan car can run any Nissan engine. There are two classes in the JGTC, 2 350Zs (GT300 class) are using the VQ35DE and 4 (GT500 class) are using the VQ30DETT. Here's the background of the turbo'd VQ into the JGTC:

Late in the 2002 season and for all of the 2003 season, the R34 GTRs in the JGTC ran the turbo'd VQ30DETT (NOT a VQ35, it would not hold up to the punishment required!).
Here's Nismo's 2003 GTR that won the driver's points that year:
http://www.nismo.co.jp/M_SPORTS/entertainment/download/wallpaper/no5_800.jpg

Presently, there are 6 Z33 Fairlady Zs (known as 350Z in the US) being run in the JGTC.

The 2 350Z's in the GT300 class running the factory VQ35DE engines (upgraded for racing obviously). Both are team Daishin:
http://www.jgtc.net/race/2004/04team/04tm080en.htm
http://www.jgtc.net/race/2004/04team/04tm081en.htm

The 4 350Z's in the GT500 class which have taken over the GTR's role including running the turbo'd VQ30DETT. (Again, not the VQ35!) There are two under NISMO (#1 Xanavi & #22 Motul), one with Hasemi Motorsport (#3) and one with Team Impul (#12 Calsonic). The #'s are the cars number on the side, not their present ranking.
Presently Nismo is leading in team points, but is 2nd (car #1) and 5th (Car #22) in drivers points. Hasemi is 4th in drivers points while Impul is running 12th.

Here's the car info:

Yup, you're correct.

Well I never said I was an Engineer, not perfect. hehe.

Thanks for the clarification GT.

Wow, I sure do wish I had the speed channel.

Wow, I sure do wish I had the speed channel.

Well, if you've got or can get Spike TV, check this out because they are starting to show JGTC races and D1 comps.

http://www.redline-tv.com/

Oh yea I watch that on saterdays. I dont really like it, because now drifting is becomming bastardised on TV, and I dont think they show what drifting is al about. Have you seen them show drifting on TV? They make it seem like all drifting is, is people doing downuts and burnouts. Its MUCH more to drifting than just that. Everything in the US gets bastardised..First street racing, then Skylines, now drifting...the one thing I had left. WHY!?!!?!?!?

there is no such thing as an r35. but this was covered. hcr, bnr, blah blah. chassis codes.


question though....ive been hearing rumors of Nissan using a 4.5 litre v8 provided by Nissan Cima for the GT-R. anyone else hearing these things?

Yeah, it's posted in the main forum. The V8 could also be a 5.4 or 5.6L variant of the Titan's VK.

and i thought this thread was dead.......if its going to have a V8 than ill just go and buy a c6 corvette

TOP SECRET is useing a V8 from the Cima and putting it into the new Skyline (G35).

a v8 haha....

thats funny and sad to heavy.

a v8 haha....

thats funny and sad to heavy.

It isn't as heavy as you might think. Although they weigh more than a VQ, the VKs are still less than an RB.

i would never buy an imported V8 specially if its from the skyline, If i want a V8 car than I would get a C6. Skylines should stay with 6cyl.

Uh, you said that already.

It isn't as heavy as you might think. Although they weigh more than a VQ, the VKs are still less than an RB.

Really damn I figured an inline six would be light considering the layout was used in the noble m12 gto. But the rb does look like a heavy engine with all the aluminum on the exterior like the GT R on the engine plate. Ask for me this past sat I saw my first skyline up close. r33 gtr... Cant say who cause the shop and its racers do not want to be know but it was a splendid site.

The Noble uses a Ford Duratec V6...just like in the Contour/Mondeo. It is twin turbocharged, though! :) The newest models use a 3L like in the Taurus. True, the new M400 model uses all kinds of engine management tricks from Roush, but the block is probably just about the same.

Now if the VQ and VK were iron, they might weigh more than the RB(more parts or more cylinders), but they're actually aluminum.
