Skyline r34 gtr vs C5 z06

skylineGTR_guy · Nov 14, 2003

go to a local shop and get your car sponsored and slap some N1 turbo's on that bad boy!

RazorGTR · Nov 15, 2003

Well I set it by the road and on the dyno it made .7kgs less than I thought! bugger, 256kw or 343.3 hp at the wheels.

'98 Corvette (344bhp) - 8 mins 40 secs

'99 Skyline GTR (276bhp) - 8 mins 28 secs

Of course with any lap times (particularly at the Nurburgring), driver skill and knowledge is vital and can have an effect on times.

Still you will struggle to find a better circuit as a test of a performance car as an overall package.

If you want a comparison on the times the current lap record for a road car on road tyres is:

'03 Radical SR3 Turbo - 7 mins 19 secs

Bloody quick or what!

the skyline has had the record at Nurburgring for How many years know??

skylineGTR_guy · Nov 17, 2003

the skyline was undefeated for 3 years in group N (sedan) racing in japan. Not bad!

Quattro · Nov 17, 2003

i've got a movie from the new NSX-R and it got 7.56 !!

OoNismoO · Nov 17, 2003

i really wanna see that vid of the nsx-r.

Driftster · Nov 17, 2003

It's at racingflix.com........Gan San Drives it.

rollazn · Nov 19, 2003

Yep.. i seen it too. It beat the Z06

and noone believe it. people who loved the Z06 said "the driver of the Z06 wasnt trying or as skilled as the driver of the NSX-R! if they had the same driver the Z06 would win"

I wanted to slap the *** out of him just plain old excuses. The driver of Z06 was a professional race car driver too, but i wouldnt hes better than Gan San but i dunno. Anyways yeah the NSX-R beat the Z06 so think of how the new GT-R and NSX will do.. i rest my case. thank you

About the JGTC, hold on a minute. It's not like NASCAR, where the cars only resemble their stock counterparts. the cars you see in JGTC are very representative of their production counterparts. You're allowed to tweak suspension, car aerodynamics, and safety equipment, and not much else. Some components may be strengthened to deal with the greater stresses of sustanied pracing, but the performance is the same. The way one car compares to another in JGTC is actually a quite good indication of real world performance. That's why it's such an important marketing tool to the manufacturers.

Jay · Nov 19, 2003

yeah but doesnt the JZA80 supra (in JGTC)use a 3S engine, when it should have the 2JZ

Driftster · Nov 19, 2003

Viper, you know why the JZA80 supra has the 3s? Because the 2jzGTE isn't a desired road race engine to be used, considering if you win weight is added.

im not worried about which engine is better for track or racing.
what im getting at is takumi says they have a good indication of real world performance and they can be modified to much, but they DONT even use there original engine types. to me they arnt much better than nascars exept they used real car bodys (JGTC)

skylineGTR_guy · Nov 19, 2003

except nascar doesn't use factory engines or body's. According to the JGTC sporting regulations: As long as it is by the same manufacturer, an engine from a different model car can be mounted.

Boost Lee · Nov 19, 2003

I'm glad we got that sorted out.

neanderthal · Nov 20, 2003

i would say as long as you can change motors to anything else in your stable then that is not really representative.

speedvisions touring car and GT series are representative.

I agree also. Remember Peter Cunningham's NSX that crushed everyone for a period of time? The good old day's.. :lol:

If you truly believe this, then I have a bridge in Brooklyn to sell you.

Like just about every pro racing series, the JGTC cars are nothing like their street-going namesakes. They are purpose built race cars with tube-frame construction and a CF/fiberglass silhouette body slapped on top of them. They are not even required to use the factory unit-body.

The number of actual factory, assembley line parts within a JGTC car can probably be counted on two hands.

But hey, if you don't believe me, you can always get it from the source.

From the JGTC website :
"...cars of the JGTC are modified greatly from the original assembly line model..."

Another misconception. Each type of car that competes in the series is assigned an inlet-restrictor size that limits the amount of air that can get into the engine. This is just one of many, many ways the sanctioning body can equalize performance and make the racing closer. In addition, winners are awarded "victory weight" to slow them down for the next race.

In these ways, JGTC is just like NASCAR or any number of big name racing series, which seeks to create close racing by handicapping the winners. And that is, of course, the true reason why it is such an important tool to manufactuers. A Supra or Skyline-looking car beating a McLaren F1 or Diablo-looking car is great marketing fodder...

so you re telling me you saw a race where the nsx-r passes the z06, or stays in front of it? if the nsx-r got 7:56, the z06 got the exact same time. i gotta download this vid at racingflix.com, is it the vid that says nsx-r at nurburgring, or whats the title? whats it under?

rollazn · Nov 23, 2003

Yeah its NSX-R at nurburgring or also know as Ring. no they didnt really race it was a time attack, where different drivers drive the car to see what the best they can do. Both NSX-R and Z06 ran 7:56. i dont know the EXACT Z06 time but the NSX-R is 7:56.733 from the video. if you know the exact time then we can anounce the winner.

rollazn · Dec 14, 2003

Also... the porsche 911 GT3 also ran 7;56. I want to know the exact number of the Z06 and GT3 because all three run in the 7min 56 second area so the exact time would be nice. Im sure the GT-R is slower than the NSX-R on any track basiclly because a GT-R R34 hangs with a NSX Type S Zero fine they are about equal. So the NSX-R vs GT-R thing is just crazy. The NSX-R is a stripped NSX made for racing with racing suspention and such it weights around 2800lbs. GT-R had a reputation of the fastest production car around the nurburgring curcuit... i want to know the time of the GT-R because how is 8.28s one of the fastest time for production cars around the ring curcuit? :confused:

audiracing · Dec 14, 2003

The skyline would probably win, but I would rather have the corvette.

the fastest i think was 7.59, but i heard that it might of been slightly tuned.

rollazn · Dec 14, 2003

yeah, thats true. On a skyline review of top gear. Tiff said Skyline R33 came with the reputation of fastest production car ever! He said the R34 was even faster. So what are the times of R33 and R34.. be so helpful if there was a real offical list.

///M-Spec · Dec 15, 2003

There is no official list for production cars because no sanctioning body exists to time the runs.

Even if one did exist, you have the issue of weather in the Eifel mountains: it changes all the time. Because weather has such an impact on lap times, there's no way to get very meaningful comparisions if different cars are driven on different days by different drivers.

Besides, there's also the issue of what consitutes a "production car". The Skyline that did it under 8 minutes is an often quoted thing, but the details of that run have never been disclosed.

-Was that car running factory boost?
-What sort of tires were on the car? Street or slick?
-Since the car was a pre-production prototype, what were the differences between it and the showroom car?

My feeling is there's no way the car was running stock boost. Many independant tests show a showroom stock R34 GT-R on street tires runs closer to ~8:25. This is very comparable to the E46 M3 and 996 Carrera. I have read that the M3 CSL will do it in ~7:58, but again, was it on street tires or slicks? The 911 GT2 is reputed to do it in 7:44 (!), but again, there are no details about the car's state of tune.

This is why I'm wary of "quoted" laps times. The car's state of tune is almost never disclosed. Hell, you can probably modify a Civic to run sub-8s at the Ring, but how much of the original car is left when you're done?

I'm not sure about that test but I do know that GTR's are detuned. Here are some examples:

1. The factory fuel and ignition maps are extremely conservative. The ignition timing factory is set around 15deg advanced. As the car begins to make boost it retards it sharply. This is done so that people (not too smart ones) can run lower octane fuels and not get detination. The fuel maps are set similarly except when boost comes on the injector duty cycle has a limit of 85%. So the GTR is only running at 85% it's potential becasue of the feul map restrictions.

2. The factory fuel pressure regulator has a very low pressure. Why I have no idea, The max pressure is 30psi. They shoudl ahve put a better one one.

3. A Boost restrictor plug and solinoid. This one has me confused. Nissan decided one way to keep the power down was to restrict the boost with not only an electronic solinoid but also a small brass plug with a very small hole. The solinoid bleeds boost off much like any other boost controller but then they put a plug in the exit line to restrict the amount of bleed. It has a very small appeture about 2mm. Boost is about 7 psi factory....yeah 7 psi woo hoo? No, It blows. Razor GTR removed the plug on his R32 Only doing that, the boost went to just under 1bar (14.6psi) Power at the wheels went from 164kw (219hp) to 184.5kw (247hp). That was the same dyno on the same day. Why the hell did they put that plug in?

As for the max boost on the factory setup it seems to be around 1.1 - 1.2 bar. The turbos will flow a max of 1.45 bar. The turbos will reach full spool at about 3,100 rpms. On a quick shift the lag on a factory set up is less than 1 sec, They recover quickly. Add a larger front mount and it decreases slightly depending on size.

Thanks for the interesting info, GTR Guy. I understand that GT-Rs make in the 360-380 neighborhood with just a handful of easy changes, but the fact of the matter is many, many cars are "detuned" from the factory, usually for fuel consumption, driveability or emissions reasons. The GT-R is not unique or even special in this regard.

true but why the boost restrictor plug when you can just turn the turbo to a lower setting? and a max of 85% on the injectors during full boost? If you want to save gas just lay off the pedal. It doesn't change anything on the low end but once you get reved up or are trying to run a lap it would slow you down considerably.

mac1987 · Dec 18, 2003

I don't think this is a fair comparison because the skyline is much cheaper (at least here in europe) and it has a restrictor build-in. If you remove the resctrictor is has 400+ HP and I think it would be faster then.

(oops, didn't read the above posts, anyway, a friend of mine's lives in australia and his causin has a R43. He removed the restrictor and reset the management and it now has around 420 HP)

Pulling the restrictor gains you about 28 HP. Re mapping the ecu give you an aditional 55 HP. Replacing the factory boost control solenoid gets you another 29 horsepower. All that gives you about 400 hp. All that was done on the same dyno on the same day.
