Totally agree Baz.

Titanium pistons, forged rods/crank...it was set up to be boosted :D

Watch the aftermarket scene take the new engine to town. Nissan had big expectations to fulfill but I think they did it (at least with the engine anyway) ... Nobody foresaw the weight gain though.

The Nürburgring (Nordschleife)

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

No-one's run an official time around the Nordschleife in a Veyron. Bugatti undoubtedly tested there, but no official figures were released by them and I don't think anyone's taken a customer car and given it to a pro driver to set a record.

I just read this thread from start to finish.......................I now feel very multicultural...............almost like I've been on holidays overseas - but I'm sure it can't last.

And the thread = pointless, sort of like comparing a speedwell to a malvern star, who cares!!!

YOU ARE MEAN RB26DETT WITH SIMPLE AMENDMENT MUCH BETTER FROM VR38DETT

WITH SAME AMENDMENT ALSO ???!!! (( THE BETTER RESULT FOR RB26DETT )) !!!

NOTE: 6 CYLINDERS V ENGINE !!! The engine failed despite the size difference engine(BETWEEN RB & VR !!

The new GTR came for the elderly and women and Ms !! Tabbies not enthusiastic

youth and brutality that must be enjoyed by a sports car!!

Yes ,, NISSAN succeeded in that!! GTR DO NOT will be the same as OLD SCHOOL GTR never!!

Thanks all ... lool :dry:

Hello.

RB26DETT ENGINE much better in all cases!! And everyone will know that soon in the coming days shown patience !!!!!!!!!!!

Thanks ALL............. :D

RB26DETT ENGINE much better in all cases!!

better?

let's compare a few important points

oiling system - NO

rods - NO

pistons - NO

cam timing - NO

tractability - HELL NO

power/litre - NO

weight - NO

weight distribution - NO

and even

specific fuel consumption and emissions - NO

resoundly beaten in every way that counts....apart from sentimental value...to you

What are the thoughts on the use of plasma coated bores on the new VR38DETT?

Around 1.5mm? thick.

Tear down every 12 months?

Only what I've read......

RB26DETT block, iron, don't need coating or sleeves stock.....(too heavy though)

I will try and treat bkc as if he is serious, it's tough but someone has to do it;

1. 3.8 litres is bigger than 2.6 litre, if you go to 2.8 litres I will go to 4.0 litres No matter what you do I will always have a 1.2 litre advantage. There is no substitute for cubic capacity.

2. Because of the extra capacity I can run bigger turbo/turbos for the same power at lower rpm. This means lower stress levels

3. Or I can run bigger turbo/turbos at the same rpm and make more power.

4. If I choose #2 or #3 I will have a wider power band, that means less gearchanges to get to the same speed.

4. A V6 does not have a harmonic problem like an inline 6, sure you can overcome it partially with a trick harmonic balancer and even over balancing. But at the end of the day the harmonics will beat you. Broken oil pumps on RB26's are a prime example of that.

5. The alloy blcok sheds heat better than the cast iron block, this means higher thermal efficiency. For the same calorific value going in (fuel) it will make more kinetic energy out (horsepower).

6. The effect of #5 is more than just power, it also effects the radiator sizing. You can run a smaller radiator as there is less heat transferred into the water jacket. A smaller radiator means less aerodynamic drag, so for the same power it would be faster (top speed and accelleration).

7. For some people emissions are important, for every horsepower the V35 makes the RB26 would have produced 1.7 times as much polution.

8. The inline 6 has a long run from the water pump to the #6 cylinder, this means temperature differentials along the block. We battle that everytime with high power RB's. The V6 has duel water feed from the pump, so no temperature differential, hence much simpler tuning.

9. The inline 6 length also exacerbates the crank shaft whip, it is long and no matter what you make it out of, it gets some form of whip. And that costs horsepower. Obviously the V6 crank is much shorter and has opposing conrod bearing loads, ie; no whip.

10. The same length issue affect the camshafts, the head is long, has differential heating along it length (refer #8) and hence the cam bearings induce loadings into the rotating camshafts. How many broken RB cams have you seen?

That should do for a start, let's see how the English translater works on that.

Totally agree Baz.

Best motoring foresaw the weight gain actually in 2004

VR38DETT mass of aluminum cost more light weight!! But if upgrading more problems and a few endurance and easy breakage!!!

There will be the same RB26DETT although Bas defects in the industry!! Especially if the work promotion to the RB26DETT!!

Thanks ALL ....... :P:D

ohh... bkc's from kuwait.

now I know how japanese shops must feel when people from australia send them messages translated from english to japanese using babelfish.

VR38DETT a series VQ + HRVQ with some modification A Result series VR38DETT simply failed engine failure murderer you will see it soon!!

Why are you surprised a lot for the engine failed, in fact??

Thanks ALL ...... !!!!!!!!!!

    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.
