Skyline motor in 1994 nissan 300zx

[wackawacka]

Yes, in fact it is.

[otto_3478s]

Damn!!! Brb im goin to throw one in!!!

[ed300zx]

Do they have sarcasm down under?...

Wait, what is an ECU and wiring?.... I thought all you had to do was fit the engine under the hood.

(for the sarcasticly challenged, all sarcasm will be bolded)

i didnt know what fact n facts was....we dont have that show here

and a super fc isnt engine management.......you can totally use the z32 ecu for an rb engine

is that better? looks like we do have sarcasm down under lol

[otto_3478s]

Its accually The Fast and Furious movies we are referring to. This "Series" includes things that are know as ultra gay to most car enthusiasts that include, but are not limited to, outrageous body modifications, unrealistic racing scenes, and excessive use of nitrous purge. The series is nicknamed FNF on the boards for usage simplicity.

ahhhh ahahahahah ok i get you now. it makes sense now i read over it

lmao funny as

PS: no im not being sarcastic cause its not in bold

[otto_3478s]

Well I hope your sig picture isnt being sarcastic eaither! HAHA

[ed300zx]

Well I hope your sig picture isnt being sarcastic eaither! HAHA

ahh nar its not

but if im int he process of putting a vh45 turbo in my zed does that mean once done the sticker is being sarcastic??? cause it wont have a vg30dett

mmmmm ill have to get the sticker remade i think lol

[otto_3478s]

Just make the 6 an 8 and be done.

[ed300zx]

but it wont be twin turboed lol

[sampsonJ]

Ok,

Let me make this painfully simple for everyone.

1) I never spoke about the time involved.2) I never spoke about what would be best in the Original posters situation.3) Im not even speaking of a 300zx swap.

I simply asked the reason WHY people would claim that the VG is a better engine then the RB. Im not talking about hypothetical situations. Im talking about objective reason(s).

Furthermore, the 300zx (at least in America/Canada) is the best selling import sports car of all time. Since the number or VG's here WAY WAY WAY WAY outnumber the number of RB's or 2J7's you would expect to see many many many more higher HP cars that include the VG. This is simply not the case. When is the last time anyone has heard of a skyline swaping out the RB for the VG? or a supra going with a VG? .... anyone? ever?

Now ill ask this again... and please dont respond if you are not going to give me a real answer since this had devolved into FnF talk.

Why would you claim the VG is superior to the RB ? go.

-----> id also like to make clear my love for the VG. I NEVER SAID IT WAS A BAD ENGINE. I said that i love my car for what it is... not for what i try to convince myself it is.

[nsrZ32]

Why would you claim the VG is superior to the RB ?

If I get a chance later I'll have to search around as a company in japan built a VG30DETT and an RB26DETT to the same specs and found the VG to make more horsepower and torque and to be more durable with the same modifications. It was quite awhile back. I'll try to find it for you.

Thank you.

That is all i wanted. Sorry if I sounded like an ***, I only wanted a real answer.

[tg]

wow this thread fails pretty damn hard!

SARCASM PEOPLE, ITS CALLED SARCASM!!! odds are the OP will never do an RB swap because a) he referred to it as a skyline engine and b) he doesn't really seem to be the type to make his own engine mounts.

GEZ.. you fail to recognize that a this thread is about a kid who wants to know if he can put a SKYLINE motor in his 300zx...and that is how I was trying to keep him, advised from despair and disappointment because of this youth and lack of knowlegde.

It would of been so much easier for you to make a new thread and then I would be able to answer you.

But your persisance...

I am not going to give you all you want but here's a start...

ROUND #1:

nsrZ32 can say all he wants. But in the end... rb26 is a straight 6...

this is the link...to explain why inline 6 is superior to v-6s..

<From link Begin>



As shown in the picture, straight-6 engine is simply two 3-cylinder engines mated symmetrically together, thus piston 1 is always in the same position as piston 6, piston 2 the same as piston 5 .... in other words, the engine is balanced end-to-end and requires no balancer shaft, unlike 3-cylinder engines. What about vertical / transverse forces? like 3-cylinder engines, the vertical and transverse forces generated by individual cylinders, no matter first order or second order, are completely balanced by one another. The resultant vibration is nearly zero, thus inline-6 is virtually a perfect configuration.

Inline-6 is not the only configuration can deliver near perfect refinement, but it is the most compact one among them. All boxer engines are perfectly balanced, but they are two wide and require duplicate of blocks, heads and valve gears. V12 engines also achieve perfect balance, but obviously out of the reach of most mass production cars. Automotive engineers knew that long ago, that’s why you can see most of the best classic engines were inline-6...

.. at the bottem of the link...

However, BMW is still loyal to inline-6 engines. Ultimately, inline-6 engine is more efficient yet smoother. V6 has more energy loss because it duplicates valve gears and camshafts (which increase frictional loss), while the use of 2 cylinder banks leads to more heat loss...

<From link End>

What does that mean... the VG has to work harder to get the same horsepower...to me thats sounds like a PITA..

So makes you wonder why people say 2JZ or RB26 > VG30... just a simple ECU tune one each of these engine... the straight 6s with yeild you the most performance than the more ineffecient energy burning V-6...

Further...How many vg you see that are drag queens... how about 2jz...or rb26...

You are correct, the post was made by someone who wanted to know about a RB swap. However my question was in response to a comment given to him.

The information you gave me was exactly what I already knew. Im saying that I had always thought the RB/2J had 1) more power and 2) more potential.

I want to hear the other side of the argument you just presented. Why would anyone say the VG is superior to the RB?

As for my persistence:

Nothing in the world can take the place of Persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan 'Press On' has solved and always will solve the problems of the human race.-Calvin Coolidge.

[raremotive]

You may already know... and maybe I intend to make it hard for that someone who made a bold statement to explain why...

As far as persistence, I agree... learning and seeking another perspective can make one better. But then there's about respecting another with that persistence. There is good and there is bad.

Persistence in another thread.. good

VG > RB in cost analysis... i'll admit.. mostly due to our geological location and our government But I never admit it mechanically

[Bohemiangod]

TVR Speed6 > RB > JZ. There we go. now that is better lol. NA Straight 6 making more power than turbo'd 6's. mmmmm Turbo Sagaris. That would be awesome.

[Chrispy300]

Hands up anyone who as actually driven a GTR? Or any car that has a RB26 for that matter? Several of my mates have them including one with over 400awhp, they sound nice and go pretty hard, but definately not worth the hassle in a Z32. Oil pump problems are rife in the early R32 RB26's and finding a good one these days is getting harder and harder. To be honest I would say that the VG is a more reliable engine. Have a look on Skylines Australia at the "How did you engine die" thread, hours of reading

Awesome motors that's for sure, but not in a Z. 400cc's less displacement, hard to get (for you guys in the states) and spare parts can't be had from the local auto shop. Bomb out your VG or do the VH conversion.

As for the better or not 2J/RB/VG topic. My prefference goes to the 2J, massive power with just big turbo, injectors, tune and a clutch strong enough to hold it all Bullet proof bottom end and sounds fantastic on boost

[perana]

heres why i think the vg is better.the stock vg block is stronnger than a rb block (fact) r32 gtr rb 26 blocks are weak and destort under high boost.all rb's have a oiling problem.r33 and r34's have a diffrent crank,sump,oil pump,cooling system(fact).to make more than 850hp with a rb you need a N1 or GT block. the vg has no oil problem a slight cooling passage problem(can easily be fixed) rb's run at dangerous tempretures when making high power at high boost (same problem with a vh41/45).if you compare the lesser rb's to lesser vg's its easy to see what **** they are.the rb is like a gen1 chevy small block,its a engine that not the best from the factory but the arftermarket makes it the best thing money can buy. the rb's brake oil pumps,split the blocks at#5,6 cylinders and the standard cranks are a huge problem at massive power and rpm(fact) i can prove this cause i spoke to 3 owners of the fastest gtr's in the world.i dont want to repeat what one of them said about the vh45 engine.yes i owned a r34 gtr.cheers

[perana]

oh the 2jz is the best out of them all.this is what the owner of a 9sec gtr and a 10sec z32 told me"the 2jz is a superior engine,it has a number of features that make it better.main and rod journal size,siamesed block,superior oiling system" this is what he told me when i asked him about thier racing z32"what i can tell you is we did not brake any oil pumps,any blocks,any gearboxes.the vg's block,crank,oiling system is above that of the rb's"this is what he said when i asked him to swap"i cant swap my zed for yours but i'll swap it for a night with your wife.lol" i agreed but my wife refused his offer lol.

[tg]

I think that something that is being missed here is when the engine was originally designed and how long it was used...

The 2jz as it is found in the Supra RZ TT was conceived in 93 four years after the vg30dett was conceived in 89 (and was used until 99 -- testament to its reliability), and the r32 which was also conceived in 89 went to the R33 rb26 then to the R34 RB26 (most of these are significant revisions with internal alterations) all while the vg saw only minor revisions related to emissions throughout its entire lifespan.

As far as real world experience, I have two friends who drive high power (400whp+) R32 gtr's and both of them attest to mechanical problems as being quite frequent.

The 2JZ is nice but sticking one in a 300zx is a bit more than the average enthusiast is about, not to mention that the alternative is driving a bug-eyed supra ;\ No thanks.

i dont think a vg makes more bhp but its close pentroof and hks build those motors to the same spec and the vg was 10hp(pentroof).14hp(hks)less.i have seen it in real life too a mate has a holden rb30et with rb26 head and he used his turbos,injectors,ecu on a vg with the same size cams and it made 21.5hp less in the same car on the same dyno.but its cause the vg revs less and the head flows less.at the same rpm the vg made more,but not at peak.cheers

[sky33gtr]

i think its a good swap and worth it

[nsrZ32]

i think its a good swap and worth it

And what personal experience do you have of an RB series motor in a Z32 versus the twin turbo VG?

[sampsonJ]

And what personal experience do you have of an RB series motor in a Z32 versus the twin turbo VG?

His sig says he has one?

[nsrZ32]

His sig says he has one?

He has no sig and his vehicle is listed as an s13 with an RB20. Very different than a Z32

Jerry start banning people man -- i'm getting tired of all this VG hate ;(
