the RB26 has been measured to produce 300-320rwhp in many instances...the VG30DETT produces about that much at the crank

how do i know? adam (MGBRaceman) dynoed his Z32 (nearly stock) and produced 275rwhp

 

Well hoorah for "whatever shop it was".
Like what???!?!?
Z32's were not intended for drag racing.
Where the hell are you getting your information??!?!? Z32's are extremely popular in Japan and a favorite in the UK and Australia. It was not as popular in the US, because for $36K most Americans in the market for an expensive sports car would have bought a Corvette.

And please note, I never said that the VG30 was better for swapping into the lighter, more nimble Nissan chassis'. Only that it is the stronger motor in the family.

If you'd like to argue numbers and facts, great. But please do some substancial research before you make these dumbass assumptions.

In stock form? I am not buying that.
Stock claimed HP is 300 for the 5speed and 280 for the automatic. It probably makes 230~250 at the wheels.
That's very nice for almost stock form (I'm assuming he has upgraded filter and exhaust). I'm dynoing mine tomorrow. I'll let you know how I do.

 

A stock R33 GTR puts down about 190HP ... to 4 wheels



Skywalker: Where are your facts? You keep saying that you're talking with facts and Heat is talking with facts. So ... the facts are ... where?

 

What are you getting mad about? It's impossible to count exactly how many of each there are. Seriously, the rb26 is way more popular, you're just being stubborn if you don't accept that. Why don't you show me why it's wrong instead of asking me to prove why it's right, it's just common knowledge.

 

No problem, what would you like to see info about? I can dig up links.
I never said anything about popularity. And what the fuck are you talking about "why it's wrong"???


But I guess you have nowhere to go with this.

 

It performs better, thus more popular. Let me rephrase the last part for you since you didn't understand it.
All you're doing is saying, no you're wrong instead of showing why it's wrong.
You're basically asking me to back up what I say without you doing the same.
Like I've said, I think it's pretty common knowledge that the rb26 is a better engine. How do I prove that? Well I can go post about quarter mile times, but I'm sure you'd counter with the argument that skylines are awd, thus getting away from the engine itself. So the only thing I can think to sway this argument one way or the other is that the rb26 is used much more frequently (i.e. popular) in automobiles that push the limits.
Now, for your side, why is the vg30 better?

 

Aiight dude, all I said from the start and all I've been trying to say is that the VG30DETT is a stronger motor. Capabilities after modification is totally unpredictable. You keep going off on different tangents. Motor Zone in Australia had a great website dedicated to both motors and had a great comparison of the two. Unfortunately their site (www.motorzone.com.au) is down and I only have a printout of the VG30DETT article. Since I don't have a scanner, I'll type it out for you. It's only fair, since I've asked you to back up your arguments.

"The Nissan VG30DETT engine produces approximately 300HP in its standard form. That's 100HP per litre! The VG30DETT features quad overhead camshafts with 24 valves and variable inlet camshafts (NVCS). Nissan's Direct Ignition System (DIS) employs 1 coil for every spark plug, ensuring that plenty of zap is available when nearing the 7000rpm red line.

Fuel is supplied from a high output electric fuel pump and distributed by a sequential fuel injection system.

On the other side of the equation there is the twin induction system. The air intake emanates from the hidden air box beneath the nose, but from there the airflow divides into two paths which lead to separate turbos, back through separate intercoolers and finally into the separate throttle-bodies of the cross-flow intake manifold.

The exhaust gasses then escape via the dual system.

Garret T-25 turbos are used in the Nissan which were designed by mixing the components of two other turbos. The end result was a turbocharger which produces boost from the bottom-mid range, with minimal turbo lag. Combined with the variable inlet camshafts, this allowed for respectable low end torque figures.

The VG30DETT's internals are also quite impressive. It has strong forged connecting rods and crankshaft as standard equipment, as opposed to cheaper cast parts. The connecting rods are also shot-peened from the factory which means that they can withstand much greater loads with increased longevity.

The stock engine bearings are racing type tri-metal lay up. The cast pistons are reinforced with steel inserts near the wrist pin hole and have cooling passages that allow oil to circulate. This keeps the piston crown temperatures in check, reducing detonation and preventing heat induced damage to the piston crowns.

The strong iron block uses a main cap girdle, which is used in racing engines to dramatically improve the bottom end.

To ensure cylinder wall lubrication, the connecting rods have oil squirters drilled in them to spray oil on the cylinder wall. In addition, the block has oil jets that spray oil on the underside of the piston crowns to reduce combustion chamber temperatures and the likelihood of detonation. The oiling system also features a high-capacity pump and fully-baffled oil pan with a windage tray.

These engines can withstand up to 600HP before any internal modifications are called for!"


I wish I had the articles printed for the RB26 and the comparisons. They were both great articles.

If you need anything else, I'll have to post it tomorrow. I'm going to watch X2. Peace.

 

ExViTermini GTR-700 Stage 1 produced more than 600hp at all four wheels on stock internals

 

So first you said it's the "mother of all nissan motors".
For the record that can be interpreted a number of different ways.

Next you said, strongest in stock form. Well that's wrong becaue the rb26 from r34 gtrs puts down more completely stock and the vg30.

So in order to avoid any further confusion, what exactly are you now trying to say the engine does?

 

The Exvitermini IS a bad ass car, and was (maybe still is) the fastest Skyline in Australia. But it was not using stock internals. It is a fully built 2.7-litre bored and stroked RB26 running custom cams, MoTeC M800 ECU and twin modified Veilside/SPL GT-3540 turbos with dual external 'gates. I could get you more but their site is down.

Try again.
