Something doesn't seem right here...
 

What's that noise?

YouTube - 20b 350z Heli's

that is unreal.. wicked :smilie_da

I wonder what the weight difference is between the 20b, and the 3.5l V6 that the 350Z came with. Any idea?

Who cares the rotary is better.

people would say otherwise Fred,
what cooler is when you can get a 20B doing 450whp na

Why the **** would anyone do that. Now hes gota carry a toolbox everywhere he goes.
Hes ****ed up his MPG.
someone asked about weight difference. okay here it is, I did the research for ya.

The VQ weights only 40Lbs lighter than the LS1, the LS is 60Lbs heaveir than the 13B-REW. so the VQ is 20Lbs lighter than the 13B-REW, but we are not talking about the 13B-REW, we're talking about the 20B, which is much heavier than the 13B. My theory, hes actually put a heaveir engine in that Z.
What a dumb **** to do that, waste of money and time.

There is a Reason why LS1 conversion in FD RX-7s are getting so popular these days.

OH, and I forgot one thing,
the VQ has 270lb-ft of Torque, I doubt that 20B has that. Hes totaly ****ed that car to hell, what a waste.

and for the people that will say, you cant tune a VQ, Watch the Grand AM series, the SR2 car has a VQ motor pushing 500HP, in NA form.


@B6T- Cant believe u just said that, Rotory is better, since when, The VQ35DE was actually developed as a Diesel at first by Renault, then went to on to be developed for Racing purposes, by then it wasnt a Diesel and NIssan was fully supporting it.

wow is it your car?
is it your money?
why do you care so much, admire the work that went into swapping that car, I cant stand people who say rotors are unreliable, everything is unreliable if treated wrong.
BTW how much work would it take to have a VQ reach 1000whp?
20B gets there faster just ask fred im sure he would know about that.

No its not my car.
I'll admire it for the fact they took a perfectly good engine and replaced it with one not much better.
and dont worry, Iam not one of those people that will ignorantly say Wankels are unreliable, Any engine is unrelieable if not taken care of. But Rotorys do require more maintance than a Conventional Combustion engine.

How much work would it take to get 1000HP out of a VQ, dunno, ask Performance Motorsports, their 1750HP 350Z is the fastest in the world.
A 350Z so fast it will make you barf - Autoblog

btw- who gives a **** if 20B gets to 1000HP faster, you certainly wont be using that in the street, or you could be like those Dyno Queen Supras, Boast about your 2JZ pumping 1000Hp, but ask them to use it, and they chicken out.

you seem like such a hater...

Iam not, far from it.
Listen Iam an Automotive Engineer in training. To me, thats just a wasted project, there really is no point to it, at least as I can see. Maybe he just did it to be different.
maybe Iam still not experienced enough to know, but can someone tell me any advantages of them doing that.

I just look at things realistcly, nothing else. I dont dream of 1000HP supras or Skylines. altough Iam planning and wanting a Twin-Engine Ford Pinto :D

Funny, there is a street driven 20B RX-7 in the GTA pushing over that number...

So how many 1000hp 2jz supra owners do you personally know in the GTA to be able to make a comment like that? There is only one in the GTA in that "range", and it is throwing out considerably higher numbers than 1000hp...And I would put money down that it will fist any street legal, STREET import in the GTA aside from MAYBE that certain rx-7.

But you didnt answer my question. Can he use that on the Street.
heck no.
there is no point in any street car to have over 500HP, how many times are you going to use it.
Power like that belongs only in one place the Track.



But now you got me intrested, can you provide more info on this 20B powered RX-7, Id love to know more about it.
Iam also guessing theyve gone the way of Forced Induction to achieve that power or am I wrong.

He's probably talking about the blue Magnus RX-7

No I can not shed anymore light about that car, maybe someone else in this thread can, B6T.

no point in any street car over 500hp? Funny, there are many in the GTA with more power than that, and most definetly streetable still. Modded vettes, vipers, ect. even measely imports. :smokin:

I know there are many here in the GTA. But my question is, are they able to utulize that power on the street, are they really going to use the Full 500HP or whatever on the street. and thats a NO.
and besides, do you really need 500HP to overtake a Truck on the Highway.
Iam not saying there are none, Iam just saying its pointless.
I think this whole Obsession with HP is pathetic, what happend to the good ol days of making simple light cars.
brings a smile to my face when I see a Mazda Miata...I mean MX-5 or Lotus Elise, or a Caterham 7. and how can I forget my current fav car, the Ariel Atom.


Dont get me wrong, I love power, especially someone like me whos wants to work on F1 cars in the future. I love power as much as the next guy, but for the street, you dont need a bazillion HP.
and besides, I care more about the Power Curve than straight on HP.

Damn, sex on wheels :smilie_da

Ahhh yess the atom...

While I agree that light cars are more fun...

but have you ever driven one? I'm going to go with no.

So, now I ask you, have you ever thought about how it would be to drive one?

I bet you it would suck. Not that the car sucks, i'm sure it's quite the peice of machinery... but the whole driving experience would suck...

No windshild... u'r have to wear a driving suit and helmet all the time... now if u'r going to only drive it on the track, then u'll be doing that anyways... but u'r talking about road cars here, so u'r have to wear a suit and helmet with that car on the street, so that bug and stones don't take out u'r eyes and pelt you in u'r face, neck, and any part of your upper body that is exposed.

You're coming in here with un-realistic expectations... talking to a tuner crowd about 500 HP being too much... well, from first had experience you are wrong. My friends car makes that much to just the front wheels, while he might not use all of it all the time, he can if he chooses to. Another person I know makes over 700WHP in an integra... It's a street car and it's in the GTA. Sure he can't use all 700WHP on the street, but he can dial it down a bit and use a lot of it (say 500+ for arguments sake) on the highway against a bike.

BTW, there are stock benz's (S600 and the like) that make over 600HP stock...

:lol_hitti you can buy a basic atom with an ecotec in it

of course Ive never driven one. the Atom isnt legal here (I think so).

Now, you said your friend in a Teg can dial it down to say 500HP to use against a Bike, okay, I'll counter that with "thats ****en retared if your street racing". one thing I hate is street racing, take it to the track.

and thx for telling me that there are stock Benzes pushing 504HP. I didnt know that. :P:haha: :lmao:

well boo hoo for u... you don't like street racing... so what? no one said u had to street race u'rself.

re-read my post... i said 600+ HP...

Uh oh, here comes the "take it to the track". I'm guessing you've never gone, in a modded car, to CSCS?

Not that one. :smile:

have you been under a rock the last few years?
Look these up
SL65AMG
EV12AMG
**** theres more i just cant remember some.

Holy
Didnt you read my post, Iam an Automotive Engineer in training, soon to be a Race Mechanic. and European cars are my passion. OF course I know about those cars and the in and out of them.
I just didnt want to go edit my post cause I was at work, to lazy to do it. But some of you took it way to seriously.
I choose 504HP because the first Benz that came to my mind was that Banana Benz, the CLS55AMG. with thats right 504HP. I know there are faster Benzes out there.
I thought adding the smiley people would reconginze it was sarcasm, guess not (again).

and trust me, I know every single car with over 500 oppps 600HP in the market, including the european market. I diffently dont need anyone to tell me that.

^ You aren't the only "engineer in training" posting in this thread... I can count at least two others...

You are right about the rotary regarding maintenence, it does take a lot more maintenence then a modern day piston engine. In other words, it actually requires *some* maintenence. It's not one of those engines with a 100,000mile service interval where you just add gas and go, you know the type I'm taking about... the type that comes in your Mom's minivan, the type designed for the average consumer who doesn't know their ass from a hole in the ground when it comes to engines. The rotary will never be a good engine for a commuter car, it's far too bad on gas, too loud, and doesn't burn clean enough without the aid of expensive and heavy emissions equipment (NA RX-7s come with three individual catalytic converters and an air pump). Compared to the piston engine, the rotary is a much newer design, and hasn't been in development for nearly as long and by nearly as many companies (this is where some people say it's because it's a failed idea). Mazda is the only company who have really been persistant with the development of this engine and have been making considerable progress. The award winning 240hp Renesis RX-8 engine (which is based on the 13B) 15 years ago only made 160hp, burned more gas, and polluted significantly more.

Where a rotary really shines is on the race track... with only three basic moving parts and the ability to make 2-stroke like top-end power, it's reliable (when tuned by a person who actually knows what they are doing) and powerful. For those of you that say it is unreliable and will blow up, or spit out apex seals... then maybe you should consider that a rotary will only ever be as good as the person who built and tuned it.

You are wrong about the torque though. A rotary can be tuned for low end power just the same as a piston engine. Logically, if you have ports designed for high end power, you're going to suffer in the lower power band, just like a big cam in a piston engine. A rotary is no different in this respect. A torquey rotary will fall on its face in the top end just like a torquey piston engine, and vice versa. Just today I was driving around in my RX-7 shifting at ~2000rpm, and easily out accelerating most cars at the stop light. The geometry of the rotary is far different from that of a piston engine. Where a piston engine has stroke, the rotary has eccentricity, which on a Mazda rotary is only 15mm. If you can somehow compare that to the stroke of a piston engine, you'll find that it is significantly less. This gives the rotor in the engine a lot less leverage on the eccentric shaft (crank shaft) then a piston and rod has on the crank journal. What makes up for this is the firing pattern, which is once per revolution per rotor. Whereas a piston engine fires its chamber once every 720deg, the rotary fires once per 360deg, which is what helps to overcome the short comings of the engines geometry. This is also why some people consider a rotary to be twice its actual displacement, and is the cause of many arguments between race teams and their controlling organizations.

If you're aspiring to get onto a race team, I suggest learning more about these engines. It's always beneficial to know what you're up against.

No.

From what I've heard, that 20B has only a fraction of the modifications the car I'm taking about has. The blue car has run faster in the 1/4 mile though...
