Mention engines yes great goodness to move car is.

GT-R NEW 2008 make much happy happy fun time on track or road.

GTR Older R34 much very good car but no up latest engines technologic before advances

3.8 = bigger filling of hole with the juice and more much internal goodness of happy explosion. More make pushing forward and thrust into back seat of.

Taught grammar by Yoda I was.

Anyone who loves participation can be read subject from the outset to understand what is on this topic!!!

Child big problem!! ;)

"Child big problem!!" :P

lol thats the funniest thing ive ever rear, and the spanking smiley on the end makes it even funnier lol

where is he from? i think he does make sense, but i cant quite grasp what hes saying..

lol

:ph34r:

bahaha

It is not rocket surgery, have a look at the spec sheet for the 38. Wins hands down.

what exactly is "rocket surgery"?

funnier than roger cordia saying "hot water balloon"

cough.

best thread ever.

if you're comparing std engines, obviously the 38 will be better than a RB26, or even when stroked to 28.

a car that screams to 100km/h (supposedly) in 3.5seconds, and does the 400m in 11s is ONE f**kING FAST car (altho mines quicker ;))

even RB26s that have been "modded" wouldnt be anywhere near as quick as the new R35....

...like f**king hell, this new GTR better not have the same demons haunting it, that being the oiling issues, the GTR oil pumps from what i have heard all suck, even the N1 item etc. but yeah its a standard item, but thats only the pump itself, not the rest of the 'oiling issues' :(

Because LINE ENGINE IS BETTER FROM V ENGINE !!!!!!!!!

Thanks ALL . :(:yes:

Hmm perhaps inline engines are better, i dont know why but yeah, i remember my engine building saying how much he loves RB motors lol.

and if the Z-Tune does do 10s or 11s supposedly, i'd rather the Z-Tune... but thats more than the R35? Im pretty sure a R35 with a few bits and pieces would become even quicker....

A new, much better car is a lot more expensive than a 5-8 year old second hand inferior car, what's your point? Did you know that you can get a VL turbo to do 10 second quarter miles for about a fifth of the price of an R34 GTR? Clearly the RB30ET is a superior motor to the RB26DETT.

You better not be taking the piss outta RB30ETs... for drag racing I'd probably much rather a RB30ET than a RB26, if i didnt want to spend too much, nothing wrong with the RB30ET... I still dont know why i got rid of my old RAJAB built RB30ET :(

oh and as a matter a fact, the one of the fastest VL TURBOS is powered by, yep a RB30ET, best time of 8.6seconds, pretty much a street car, fkn quick.

fkn hell. shitty rb26/30, worst idea ive ever had!

bkc, i suggest you talk to Nissan and convince them with your thorough reasoning that the RB26 is better. Imagine how much money you'd save them if they dropped this new V-engine R&D nonsense and chucked a good ol' RB26 in each new GTR. They could hit HKS up for a pair of 2530s and f-con, chuck on some 555cc injectors and a fuel pump which they could get at mates rates from the boys over at Nismo and then get her over to the workshop down the road to give it a conservative tune on 1.2bar on their dyno.

Here's a short analysis of power and torque figures:

Last (R34) RB26DETT: 206 kW @ 6800 rpm and 392 N·m @ 4400 rpm. At peak power, the RB26 is producing ~290Nm of torque ie. dying in the arse.

VR38DETT: 353 kW @ 6800 rpm and 588 N·m @ 3200-5200 rpm. At peak power, the VR38 is still producing just under 500Nm of torque. ie. not dying in the arse.

The VR38 develops a lot more torque and has a far wider spread of torque. It complies with the latest, strictest emission regulations, ie. it makes this power quietly and efficiently. Nissan have spent who knows how many millions of dollars making sure this engine runs PERFECTLY, in every sense possible. No misfire, no vacuum leaks, no setting the boost controller to get rid of spiking or boost drop, the boost delivery is flat and perfect, the torque curve is massive, the power smooth and endless. A tuned RB26 doesn't even come CLOSE to standing a chance (on any count other than outright power), let alone a stock RB26.

HTH

You can't Quote 206KW's for the last Nissan GTR34 ...Gentle-mens agreement and what-not.

It was more like 260KW's..and that was without a good computer.

RB20..25...26...motors were dropped because of their emissions(Not meeting new standards)...Nissan just got the R34

in production before the cut off date...luckily for us.

So most of what you are talking about is flawed.

If you had a N1 R26 Block..Forged N1 Bits and pieces...N1 Turbo's..555 injectors, any current plug in computer..and slapped a DSG box in a GTR34 you would more than likely eat the new Nissan R35 alive.

I am sure you would be able to tune this for 320RWKW's(Safe)and then if you applied the Power to weight ratio....

You're suggesting Nissan's engineers can't develop a good computer for the RB26? IMO you can't compare anything aftermarket with the sheer money the factory spends on engineering. Don't confuse the typical goals of running 11 second quarters and then putting up with no power until 4500rpm and a lack of driveability from a 2.6 litre motor with Nissan's goals of smooth power everywhere, acceptable consumption, complete legality emissions and noise-wise and the potential for the motor to last >200,000kms while still being faster than most factory cars produced.

We're talking stock for stock. It wasn't a comparison i made first. If we're going to compare cars with aftermarket modifications we might aswell wait until some of the Japanese tuning houses get into VR38s.

Weight to power: R34 260kW/1540kg = 5.92kg/kW

New GTR: 353kW/1740kg = 4.93kg/kW

The Nürburgring (Nordschleife)

7:38 - Nissan GT-R, 480PS/1720kg (manufacturer claim)(Nissan 10/07)

7:40 - Bugatti Veyron 16/4, 1001PS/1888 kg (Wheels magazine Australia, 12/05)

7:42 - Ford GT, 550 PS/1521 kg (as indicated by Octane magazine, 11/05)

8:01 - Nissan Skyline GT-R R33, 280 PS/37.5 kgf·m/1540 kg, Motoharu Kurosawa (Best Motoring - Video Special DVD Series

8:22 - Nissan Skyline GT-R R32, 280 PS/36 kgf·m/1430 kg, Motoharu Kurosawa (Best Motoring - Video Special DVD Series

New GT-R ran that time in PROTOTYPE form AND SOME OF THE TRACK WAS WET.

Is this reasonable not believe it!!!

I saw this video before and not anything new!!!

AUTO + f1 assumed that the Fund MANUAL GEARBOX WHAT THE result ? will be no space between what Do not forget that the Fund Gears AUTO !!!!!!!+++++ F1

Many faults!!!! And are faster!!

No fun in a car carrying athletic fund drive AUTO +F1 !!!!

Unfortunately fun ended GTR !!!:verymad::(

I do not want to talk about the engine!!!! :):(:(

THANKS ALL .......

I think he said because if has F1 type gearbox the car is no longer fun, and because of this he will stick to his stick shift RB26 powered GTR.

That is completely irrational because he was asking which one is better. Technically and by the numbers the VR38 destroys the RB26.

As for bang for your buck...I don't think you can beat a second hand R34 GTR...half the price and I'm sure you can get near equal amounts of fun.

You can't compare a standard VR38DETT to a modified RB26DETT. End of story is that in standard form the VR38DETT is far far more technically advanced than the RB26DETT. No one has modifed a VR38DETT yet so who knows the potential of the motor, I mean how much power would a VR38DETT make if you removed all the emission crap, fitted up a free flowing exhaust, boosted it up and gave it a retune? I'm sure it would be a hell lot more than the factory output, especially with such a large capacity and a pair of decent turbos hanging off the side of it.
