what type of gas do you use

for all the GTR owners in the US, i was wondering what type of fuel you use? I'm asking cuz i'm seriously considering an rb26dett swap into my 240z. I am wondering if there is a way to tune the rb or the ecu so that the engine can run on california 91 octane. if not, what alternatives are there?

Get the highest octane available. The RB26 Engine along with all the rest of the Skylines were made to handle the high octane. Putting the low octane crap is doing your car injustice. If you gonna put an RB26DETT in you have the funds to do then you have the funds to get the highest octane.

They will run ok on 91 octane...... just dont go crazy on boost ... dont use a Japanese ECU that has been tuned...

If you use a Power FC and tune it for 91 - no problems... stock ECU and run stock boost - no issues.... start cranking the boost - you had better be putting good fuel in it...

Highest octane you can get, just remember its not the octane that get you more power, it the ability to adjust your timing without detonating that gets you more power.

I run 94.

Honestly - higher octance can mean less power....

It burns slower so you dont get a complete combustion.

I heard of going from VPC16 to VP 104 unleaded octane - and with retuning made another 20 hp on the dyno.

But thats going from 117 octane fuel to 104 octane fuel..

92 octane is fine, just richen the fuel going to the engine to prevent detonation due to the increase in boost, if it's a r33 gtr engine leave it at 0.6 bar, you could crank it up to 1.0 but that's if you get everything needed to prevent the detonation.

How do you richen the fuel going to the engine ?

Whats the difference between the R33 engine and the R32 engine , the R34 engine ?

Whats needed to allow you to boost up to 1.0 bar ?

1.getting a aftermarket ecu,a aftermarket fuel pump, fuel pressure regulator, aftermarket fuel rail with bigger injector's,or a fuel cell if you're a racer,etc.
2.with the r32 engine you can raise the boost up to 1.0 bar safely with very minor mod's,with the r33 you can raise it with the above sugestion's, with the r34 you can raise it to 2.0 with a few mod's, in the r34 the MFD's(Multi Function Display for those of you who don't know) boost gauge can read up to 2.0 bar so you can easily raise it up with a few mod's.
3.you need the 1. suggestion's to safely crank it up,hope it help's.

Let's talk skyline, oh can't understand can ya?then I guess we'll never communicate.

Ok first off - you really shouldnt comment on something you really have no hands on experience with. I did the legalization on about 60 GT-Rs . I have driven and prepared the 2 fastest GT-Rs in the US. I have taken GT-R's R32s , R33's and R34's very far apart - and put them back together...

Fuel cell does nothing to richen up the fuel mixture...

There is no real internal difference between an R32 , R33 or R34 engine. There are some minor things , but nothing that has a great overall effect.

I am driving an R34 right now . The stock boost gage goes to 1.2 bar... with the Nismo add on you can read up to 2.0 bar... but that has nothing to do with how much boost the engine can handle.

And honestly its not boost - its the physical limits of the motor... boost is just a number.

te.

You can run 1.0 bar on an R33 - no issues with stock ECU and good maintainence

I have been drag racing for a few year's, I'm no pro but I know the lingo and fuel cell's do help out because you are burning more fuel with the increased boost (on the turbo's) and the fuel cell supplies more fuel to prevent detonation.
the mfd read's up to 2.0 STOCK I don't know what you're talking about. :o
I know you can raise it up safely with everything stock, but just to be more cautious you should modify the engine. :D
-Dave

do you know what 2.0 bar is?



do you know who tyndago is?

do you know who shawn morris is?

oh wait, it's the same guy.

he used to work at motorex and legalize skylines.

don't be an ass.

and since when does a fuel cell increase the "richness" of your fuel...

he asked a few questions...
what do you need to do to get x boost in r32/33/34.

you didn't answer him....

you've been drag racing for a few years, so that obviously means you know all there is to know about skylines...

so you feel the need to look stupid talking down one of the few guys in the country that has had his hands on 1, not to mention the fastest ones in the US?

and you give bs answers to boot?

come on now...

oh, and a fuel cell is a gas tank.
it doesn't provide any more fuel.

you need to upgrade your fuel pump to get more fuel out of it.

fuel cells are there for safety, not getting more gas to your motor.

if you pour a gallon of gas through a funnel, and it gets through at say, 10 liquid psi, and then you pour a bigger quantity of gas through the same funnel, guess what...

it's still moving at the same rate.

b/c it's not the container. it's how you get things in/out of it.

in regards to the topic...

the cost of putting an rb26 into a 240 is going to be pretty pricey...

go to the 240sx forum, there's an faq about putting the rb into the 240.
that's going to get you some answers...

oh oh oh.... pick me - I know the answer.... 14.5 is one bar so x2 is 29 psi....

Originally posted by flylwsi do you know who tyndago is?[/B]

Thats - ty(phoon) (i)n dago (san diego) just in case you were ever wondering where I came up with that...

Originally posted by flylwsi do you know who shawn morris is?[/B]

Actually its SEAN Morris - my name gets misspelled a lot - but its close... still sounds the same....

Originally posted by flylwsi he used to work at motorex and legalize skylines.[/B]

I worked on Skylines for about 3 years now....

Originally posted by flylwsi ou've been drag racing for a few years, so that obviously means you know all there is to know about skylines...[/B]

I've been drag racing since 1993 - when I got my Typhoon. Since I was 19 years old. So thats 10 years.

Yeah Evo guy does not look the smartest in my eyes... I was testing his knowledge and he got an "F".....

did you bring an apple too, to help get to the head of the class????

i was going to say that 2.0 bar is approx 28 psi, and if an r34 can handle that stock, i'm reallllllly impressed...

i knew all the answers of course, b/c i've done my homework...

i'm almost to the point where i need to get a pocket protector... sooo nerdy.

thanks sean...

i wasn't sure on the spelling, b/c i've seen it both ways, and i'm sure it was right in your sig a while back, but it wasn't in SCC.

whatever...

oh, and the drag racing thing wasn't pointed at you... i know you know skylines...

it was pointed at the other poster here... the skyline piece at the end should have been followed by my buddy right here... >:rolleyes:

"F" for fantastic,hehe.:D
you think I give a damn about your crap, material thing's like car's have no big importance to me.

Look you are the person that chimed in and gave someone advice about something you know nothing about.

You dont care about material things like cars and you spend time posting in an automotive forum.....

Try posting in the flower aranging forum.....

hey i just chill here cuz i'm interested in car's and i drag raced because i was interested in that too.i don't take materialistic thing's as an obseesion unlike other people, what's with the attitude i haven't said anything negative to you and i obviously can't give my opinion without being criticized i guess lay off the crack pipe you little shi# and learn to respect people,hehe.:D

He is like a male version of Sybil.

Try that ignor function, it works:D

Thats the thing about respect-(R_E_S_P_E_C_T)
you have to give it to recieve it , and you didn't show anybody any respect by wasting your time discussing a car you know nothing about.
Maybe every once in while you should pull that black hand inside cars and pop the hood and actually TAKE A LOOK INSIDE :eek: :eek:


Since your such an EVOMANIAC (hehehehe, no fun intended)
What the hell are you doing with the Godzillas.... I mean Skylines

Here is a EVO quote to back up the fact that he is not, materialistic?
Man you must have some pretty rich parent's huh well i'm 23 right now and i own 2 skyline's a 400R and a gtr r-34 v-spec both from prospec yup i know that not that many people know about them onbly skylineusa and me i think oh well when i was your age all i was driving was a old ass gts-r r32 producing 200 hp and yes this car does exist it's a 1986 version check your info people and don't be saying that it's not real because it is but i quickly bumped it up to 390 hp later man was that rb25 useful and durable oh well i sold it for about $15000 later and bought my self the 400R that was a few month's back.

"Mess with the bull, son. You'll get the horns." Breakfast Club :D

Later that r34 Vspec became a NUR I believe :rolleyes:

The man is basically like Gandhi. So, take his word for gospel:p

so, though you sig claims you "speak skyline" and we shouldn't talk to you if we don't understand...

you call out the biggest skyline officianado in america?

to quote wayne's world...

are you mental?

for not being interested in material things, you chose the wrong board to say that...

especially after saying you "speak skyline"

but you don't care for material things...

and the last time i checked, a skyline is pretty material.

I fell into it again, "THE EVO ZONE"

It a universe that has no concept of perception, no grasp a reality, a lot of word written in lower case letter that ramble on and on about nothing, a universe that has hardly any punctuation, a place where only one mind can inhabit, because that mind is infected with voices of the delusional thoughts of the spelunkers, crawling through the vast caverns of the earth most deepest orifices.

In other words, you are mental.

Back on the ignore list with you:D

Instead of clogging up the forums with responses to meaningless posts just add the offender/s to your ignore list and make it a much more enjoyable place for everyone.

If there are definate real "issues" with anyone or what they say, ie. flaming posts then please infrom one of the moderators.



Thank you for your patients, I now return you to your normal service

your point is well taken, however, in between telling the "offending" poster that he's wrong, i've also, as sean has as well, managed to set things straight, for the knowledge of the poster, as well as the next reader of the thread.

if i manage to put my opinion in there as well as re explain the answer's validity, and the real truth, so be it...

my posts have not been all out flames at anyone, though they may contain condescending tones and ideas, keep in mind that it benefits no one to spew incorrect information.

which i think has been corrected very well by both mr. morris and myself...

until next time...

tune in next week, same skyline time, same skyline channel...

Thank you for your patients

i'm an english major, don't take offense...

it's patience...

patients are things that doctors have


(sorry)

flylwsi,

If your an English major, why don't you Capitolize?:p

english major that's cool, i'm a computer system analyst major how about you sky?let's forget about car's for one second and let's talk about career's.:)
-Dave

you are such a jack ace.

talk about careers?

why, so we can get off the topic at hand?

that you don't know what you're talking about?

i don't give a shit what you do, it's what you know.

and on this topic, it's apparently not much.

i work in the automotive aftermarket, and i'm well versed in all the shit i say.

i don't claim to know about skylines other than what i've read.

that's what sean morris is here for.

skylineUSA...

i don't capitalize b/c i'm lazy... but i spell shit right... (not that tazdev is less than me for spelling incorrectly...)

whatever.

EVO... get over it. you're wrong.

don't try to change the subject b/c it's not working. this thread should be closed.

Let's talk skyline, oh can't understand can ya?then I guess we'll never communicate.

if you want to talk careers, change your sig.

until then, the board here is AUTOMOTIVEforums.

flylwsi,

Well said mate.

Like what was mentioned before, higher octane is not necessarily good. It all depends on what your car was tuned for.

In my case, I did not own my car when it was tuned, so I play it on the safe side and run 94. Sometimes I can only get 90, so I adjust by boost controller all the way down to .6. I try not to boost at all, but with 8.5 and aluminium heads there really is no chance for detention. As long as your timing is not to far advanced.

i've seen the same in regards to octane...

one of the dyno shops around here noted that, when tuning miatas at a scca race, they made more power with 89 octane than with 92...
and that's on race modified cars...

keep in mind that cali's 91 octane is pretty crappy though, which is why the question was brought up, as i'm sure an rb motor requires at least 91 or 92...

The uhh 91 octane is do-able but not favored. I just finished picking up my Skyline and had to run 91 all the way from Cali to Missouri...Suck!!

do you have any pics of your beasts?

i'd love to see em...

The Supra engine is in the avatar. As soon as I find a scanner around campus that I can borrow I'll put some up.

Hey all. I dont know a whole lot about imports but the skline seems to be the hot ride on the Japanese import scene. Can someone please tell me what is so special about this car?
-thanks

They are all wheel drive(and even the all wheel drive system is wicked for drag launching) and the engine can hold incredible amounts of boost and push very large horsepower numbers. When I describe the potential to people who don't them I describe it like this...Think of a Supra, then add all wheel drive, then you have a Skyline.

Aside: Tydango, I may be calling upon you sometime soon for some awnsers to some questions I might have. Right now I'm not working on the car but its not because I'm not trying to get in some wrench time.

Supra650RSP.... tyndago = Sean

No problem .. I think I know your car.....

I think I have some time in it..

It wouldn't surprise me if you did.
The car is back at MotoRex right now too, so I haven't had the chance to start working on it like I wanted.
It's a long story and in all reality, I wish I would have gone through you. It would have made my life a lot easier I'm sure.
Anyways, I've still got your number from calling you a while back so as soon as I get my ride back from MotoRex I'll give a ring I'm sure.

i have a question concerning japanese cars in general
if the steering wheel is on the right side of the car, would the shifts be reversed or would they be in the same order as if they were on the left hand side?

i know it's a very newbish question but i prefer asking people who actually drive cars that have the steering wheel on the right hand side...

Tranny is set up the same way on left or right hand drive cars

1 3 5
2 4 R

Clutch Brake and Gas are all in the same order respectivly. The part that screws me up is the damn turn signal/ wiperblades.

You will get use to it

Driving on the other side actually makes sense after you get used to it. The problem for me is that when I have to go to the states I am now messed up on which side of the road I will be on. My question to those who have their skylines in the states right now is how easy is it to get used to driving around on the roads?

you guys should really get water injection, it gives more power plus makes 89 octane pump gas act like 100+ octane race gas :)

Does water injection by itself give you more power? What is the point of having a higher octane rating?

Water injection is a band aid of sort.

all i know that its widely throughout europe, i got this one eurpoean japanese car mag, and almost all the cars have it , even then european ford escort cosworth comes with the water injection system out of the factory! pay less get more !

Honestly, I don't know much about water injection? How does it work exactly?

As for getting used to driving on the streets here, I actually thought it was pretty easy to do after a few minutes. I found myself being overly cautious when moving into a left lane but other than that I thought it was pretty easy. It's also kinda awkward sitting in the passenger seat when someone else is driving. I found myself staring at the road in total boredom because I was not doing anything. It was kinda funny.

Water injection is a band aid of sorts as said. It cools the intake charge to eliminate detination. You can achieve the same effect with a large front mount intercooler. It does raise hp but minimal amount.

The good systems use a water and alcohol mixture.
