RB26DETT vs VQ30dett

whichwould you rather have in a 240? and don't tell me wether it's possible or not.

anything is possible with cash...

i would say the..rb26dett because the engine bay will be less cramped as opposed to the vq30dett.. and i like the whole inline 6 thing... i say go rb!!

and weight distrubution will be better and more evenly distrubuted with the rb then the vq..

my $0.02

Dude I just got a good job (meaing 9 to 5, 7.50 an hour) I"m 18, living with my parents (Yea I"m cool) and making almost 200 a week. So i can save or take a lone out for some money. Plus i got friends that has connections to get a cheap RB. He also done rb26dett swaps before and says it's a LOT of fabrication, but in the end it's more than worth it. so w/e. I"ll get the engine with a loan form the bank, and build it up when i get another job (that's right kiddies 2 jobs at one time) Working at one of these damn indian casinos making 12 an hour. Yea I have it al planned out lol. Too bad i know nothing is gonna go to plan loll

ok..........

im lost now...:confused:

didnt you ask which would you rather have in a 240? and don't tell me wether it's possible or not. what is the deal with the whole big explaination?:confused: ok i have a job also and im also 17 and i also make 7.50 and work 9-5, it sounds easy on paper to do a swap but when you come down to it itz not.. i understand that you will have two jobs and good for you but it will take a while to save and it get complicated you get bills you dont need and expencises you didnt have before because you now have a job. when i first got my job i was like im gona save 4g' for a sr20det swap and i did it on paper and it worked but when it came to doing it, it didnt work i only was able to save 2500 out of the 4g's which isnt to bad but not to good as well.. not meaning to put you down or nuthin i hope you do get your swap but your new here as time goes by you will unedrstand things are easily said then done what you plan for is never what you get when it comes to a car... give it time.. no i have gave up on a 240sx with a sr20det i would rather spend the money on a ka24de and making into a ka24de-t quicker e.t.'s then the sr20det.. now i have gone a completely different route im want a eclipse gsx because i will be running faster then the sr20det\ka24det 240 in a shorter peroid of time.. yes i know i went way off topic:tongue: sorrie :wink:

good luck

Err, today must be opposite day.

The RB is roughly twice as long as the VQ, and would take up more space in the engine bay. Weight distribution would be worse(or more difficult to improve) with the RB, because more of the engine would be past the front axle.

This is the reason that tuners like Top Secret are swapping VQs into R34 GT-Rs. The VQ is short enough that the entire engine can be placed behind the front axle, effectively making the GT-R a 'Front Midship' car. The weight distribution(and overall weight) is much better, and greatly improves the car's handling.

u may got me on weight distrubution but the space problem i think the rb will leave more space in there.. it jus that the vq is wide so i figured it would be more weight in the front also the same logic gose for the space issue..

id want the RB motor... it isnt that much heavier than the KA, my friends car weighs 2700 with the RB26, like 50 lb heavier than with the KA, the RB26 sounds better too.. when he's on it next to travis with his 300, the inline 6 sounds sicker,,, the 300 is at 14# and the 240 is at 17# tho... but the rb still sounds sicker when he puts it at stock 11#

VQ is wider cause its two rows of 3 cylinders
RB is longer cause its one row of 6 cylinders..
so its either 1 or the other, its down to how much u wanna spend on fab, and how much u really care about the weight.


in my opinion i'd go with an RB just cause its done more often.

and i always thought the VQ was 35DE
and the VG is 30DETT.

VG is from 90 - 96 Z
and VQ is from 350z..

whole different ball game, cause of how new those VQ's are aswell.


its totally down to how deep ur wallet is, and personally id stick with an SR instead of all these cause u guys in the U.S get raped in taxes for having ur own money in the bank.

the RB26DETT is a better motor then the VG30DETT because from the nature of a straight 6 is that you get massive torque compared to a V6's. the RB is also more rev happier and its a much more robust engine. it can handle over 600hp on a stock bottom end. it also have 6 throttle bodys. the RB is just a better motor.

Thx for saving me the typing TatII

lolz no problem

I would also agree, that the RB is the better of the two engines, but a question, why not the SR, or if you want a 6, the RB25? If you're building this car for street use (with the track day thrown in here and there), it seems a lot more practical to go with the SR because you can pump out high hp numbers regardless of which of these engines you choose, and for a lot less money, defintely enough hp for the street, at least...

it also have 6 throttle bodys

well ill be damned.. i never knew rb26 had ITB

thats like one of the few things i didnt know.. ( i imagine there are tons more, but i mean general stuff)

ITS ABOUT HALF THE PRICE OF A SR20. JUST AS EASY TO INSTALL, AND YOU CAN STROK IT TO ABOUT 2.5L WITH MORE OUTPUT THAN A RB25.

out of those 2 choices, i'd go RB26, and my reasons are the same as everyone elses. :bigthumb:

my only point is that with the money you would be spending on an RB26DETT swap, you could easily buy an SR and build it up enough to more then better the performance of the RB26. just something to think about...cause if you think SR redtop swap = 4g's and RB swap = 10g's at LEAST, then after the SR swap, you'd have 6g's with which to build up the engine. 6g's can do ALOT.

The VQ family has been around since 1995(if not earlier). There are several variants.
VQ20DE=168hp
VQ25DE=187hp
VQ25DET='276hp'
VQ30DE=190-227hp
VQ30DET='276hp'(probably well over 300hp)

You can get VQs for much cheaper than an RB as well. I've seen the VQ30DETs go for under $1k. The VQ30DET makes plenty of power, too. You see, the Japanese-market Cedric/Gloria twins use this motor, and give up little if any performance away to the 345hp Infiniti M45.

Hey, If I was you I would go RB26DETT cuz I got one in my s13 and it hauls ass (12.3@118 mph one leggin it) in the 1/4 mile. I did the swap myself and can do it again. If you need some help drop me an E-mail at [email protected]

hey S13GTR, id go with an LT1 and paint your car silver

just my .02

Let me shake your hand, my friend. Where you from? Casue i haven't heard of any 240sx's with rb's in my area. The only RB in the aera of Connecticut is a skyline in mystic, unmodded. Blasphemy, i tell you.

Dude a 240sx RB26DETT engine swap is actually not that difficult since the subframe is pretty much the same among all nissans. There is some sort of dissinformation going on between 240sx owners. The RB25DETT swap is not so hard. In fact any of the RB series swaps are not so hard. I had it done myself not more then 3 months ago to my 96 240sx. Ohh and by the way im from CT now living in AZ, you got any pictures of that skyline, I think it might be my friends dad, he said he was gona get one last year, haven't talked to them since :cool:

I hope your not trying to say that rwd and awd have the same subframes. The rb26dett is set up awd (mounts, crossmember, tranny, and a transfer case oil pan oh yeah and the subframe) and the 240 is setup for rwd which makes everything NOT bolt right up. Then if you get that sorted out there's always the steering column fab needed to clear the turbos.

:werd:

whichever motor can handle more maximum horsepower is ALWAYS the better engine

common sense

rb's can get up to 1300hp with some $$$$$$$$$$$$$$$$$$$$$

engines that can take more max HP are better for MAXING OUT ur engine, if u dont wanna MAX it out, u can go with an engine that has good response with like Stage 2 mods only. the better engine is the engine which is good for what u WANT ur car to do.

actually I didnt say they were the same, i said their pretty much the same their is a difference, and yes it is a little more difficult to do but not by that much. and its even easier if you stick with the rwd you dant have to get awd

Sr20 (red) = 2000-3500 --- rb26 = 5500-7500
-------------------------- rb25 tranny = 800-1000
Install = 500-1000----------install = 2000-3000
-------------------------------------------------------------------
2500-4500 ----------------8300-11500


Huge cost difference, so even if you're working a lot of hours you are making shit for money. With how much the SR swap costs even it would take you many months pay if you saved it all...which I'm sure you spend some of it. CA, SR, or RB25 are good swaps...don't stray away unless you are a very good mechanic OR you got a huge cash flow. Fixing and upgrading parts on an I6 or V6 will cost more than a 4 since many parts instead of buying multiples of 4, you have to buy multiples of 6.

Don't even get me started about a VQ swap while you're making 200 a week...even with 2 jobs you will be making under 2000 a month. Imagine getting into an accident that totals your car and then you're out a 10,000 dollar or more engine swap...and the insurance company will give you only a few thousand for the value of the car since most (none, besides progressive) cover aftermarket mods.

And I wish people would stop posting engine swap threads until new developments occur...aka someone successfully completes a v6 swap and documents it. It's fine to talk about this stuff, but it seems all people want to discuss is engine swaps.

Dude I just got a good job (meaing 9 to 5, 7.50 an hour) I"m 18, living with my parents (Yea I"m cool) and making almost 200 a week. So i can save or take a lone out for some money.

7.50/hr is a good job? :eek7:

That is the biggest ricer comment I ever heard.

Nobody turn this into a flame war like the last one damnit.

Id go with the VQ over the RB just because ive seen the RB done (its about to be done alot more too). Pretty much the same reason i dont like domestics - they can Rape most imports in terms of power but they do it with 2-3 times the displacement and they've been doing it since the 70s so its not that intresting to me.

And I havent really seen any tuners trying to make big numbers with the VQs (well at least before the 350z) and the RB series is a good 8yrs older than the VQ platform (from VQuick's '95 number) so i belive we have yet to see the full potential of what the VQ is capible of

as for in a 240 not only would the weight distribution be better it would leave more room up front for V-mount intercoolers and stuff like that

P.S. I dont doubt the awsome-ness of the RB (and anyone who does should have their fingers smashed with a hammer) but i think the VQ will end up being superior once it has some years of tuning on it.

hey i know where to get a rb26 insatlled for 7.5 g's :evillol:

but yeha id rathr have a rb26dett, 50lbs more than the KA thas not alot more

out of topic SR would be the best if ur short on money, basically a direct fit and good weight balance cuz it CAME with the car

personally me im going with the rb25det

:2cents:

The other thing I didn't mention about the VQ is the balance it will provide for an S-chassis car. For those who want a very well rounded 240SX that can be a giant killer at the strip, roadcourse, or the street, the VQ is probably one of the best choices. You've got good weight distribution, low weight, and good, useable power.

The VQ weighs less than most, if not all, of the other Nissan motor swaps that have been done. At only 108lbs, the VQ weighs less than many 4 bangers, including the SR(probably).
VQs are also cheap and plentiful, if you know where to look. It's not like anyone else is really using them for anything, so they should be easy to find. I mentioned in another thread that fwd 95-up Maxima VQs(as low as $400) will bolt up to the '01+ Pathfinder or 350Z transmissions. A VQ motor and tranny can probably be had for less than some SR longblocks.
A VQ motor is also quite torquey, even in stock form. With a Stillen supercharger or some of the turbo kits available, internally stock VQ30s are making well over 400fwhp in Maximas. On top of that, you can always go NA.

Basically, a VQ is very light, can be very cheap, and can be very powerful. A 240SX with a VQ swap will be the same way.:iceslolan

the VQ wighs only 108lbs? u sure about that?????

Yeah, it was in an article by Wards when they gave the VQ the 'Ten Best Engines' award for the 8th consecutive year.

I think you may have misread that. The article says is weighs 108lbs LESS than the engine it replaced. Here's the article (http://subscribers.wardsauto.com/microsites/Newsarticle.asp?newsarticleid=2666859&srid=10088&instanceid=29125&pageid=5991&magazineid=1004&siteid=26)

I'd go with the RB simply due to the fact that it is a more respected motor (couldn't think of anything else to say that it has a better background than the VQ)

The Rb has tons of aftermarket support in japan, granted the VQ is becoming more popular, the RB is still king. It'll just be easier to make power (and to find parts for) the RB than it will be for the VQ.

RB without a doubt....tons and tons of potential...YAY FOR RB!!!!

That is the biggest ricer comment I ever heard.
im getting tired of your snide remarks. WHat, is ricer about it?

http://history.jbskyline.net/index4.php
almost halfway down the page next to the blue sky read it. then get educated.

again, whichever motor can handle more maximum horsepower is ALWAYS the better engine. in terms of speed.

IT IS COMMON SENSE. all speed is only HORSEPOWER and WEIGHT RATIO. nothing else.

it would take serious money to get the rb over 1000hp.


so, what is so ricer about what i said? the fact that you don't know what you're talking about?

it would take serious money to get the rb over 1000hp.



good point, but it would take more to get a VQ over 1000. so thats why I like the RB.

Also, for anything other than 1/4 mile racing, generally you would go with the lightest engine with the most potential (thats why so many people are going for CA and SR swaps, their light.) simply due to balance problems with the 180lb gain of an RB over the stock KA (which if done right isn't all that much because with the proper motor mounts you can move it back and down enough to more properly center the weight.)

its not a 180lb difference over ka. it's 60 lbs difference.

night did the swap and it was very close to stock.


whichever engine has the best hp/wt ratio is faster.

night has a car he wants to sell me for 4.5k with a rb20 in it

do i trust or do i not trust

id trust him. 4.5k is a deal. the body must be shot, or the engine might have tons of miles.

I dont like siding with people or getting in between things when people say something to one another but i totally agree with you mynismo...how was that a ricer comment?????hahahaha....it was far from one if you ask me. anywho if you want power to weight ratio it would be better if you went SR20 (you can get like 700hp max (yes im talking with upgraded everything...lol) with very fine tuning, lol. I've only seen it like done once probably has happend more than once but i've only seen i think top fuel or hks do it, im not good at remembering things:P....but i know you all want that beef tech power so RB it shall be for that. :)

thanks latenight, at least someone understands...

the sr can only go up to 400hp on stock internals, max. granted that is way more than i need.

My rb26dett makes 400 rwhp with bone stock internals, in fact the engine has a bone stock everything.

Really!!! wow!!! thats great considering that most RB26's make "280hp" at the wheels, which is really an underrated 320hp, with 15% driveline loss that means 360hp. bone stock. at the flywheel.


:wtf:

maybe he considers changing boost levels not modifying it...?

i have to say, i have secret plans to build an 11 sec car for 6 g's, including the cost of the car.

im not telling anyone what it is. all i have to say, and sorry to say this, it isn't no nissan.

i will DEFINATELY have it by april. im going to start building it as soon as i find a good car, and will start looking for one in february. this will be too much fun :evillol: :evillol: :evillol:

sounds like your goin 5.0 on us...or maybe an iroc, there tasteless low brow type cars but i heard you can make them fast for real cheap.

i bet Old Skool Eclipse i think i remember him rambling on about Eclipses somewhere.

dsm!..haha, have fun fixin trannies. you can change you name from mynismo to mybrokentranny. :grinyes:

you got the dsm and eclipse part right..........



hmm maybe i wont do that after all. i really want an rb.

i was going to get an old colt turbo and throw in a 2L gs-t engine, it would fly but i dont want it to look THAT sleeper.... it looks a little too grocery getter for me. the car does look pretty kickass though and might be able to take a 240 stock V. stock. very rare too.

its a good looking car. hmmmmmmmmmmm

you can change you name from mynismo to mybrokentranny. :grinyes:
haha... are they really that bad?? the car is completely kickass. im feeling it.

take a look at this (http://turbomirage.phpwebhosting.com/videos/incar.mpeg)


edit: boooo... found out he was using slicks on all the runs, and on one run he did a 13.3. i want a fully streetable car.... there was an sr on ebay that ran low 12's on street tires..... not bad, it went for $5700.

i used to sell mitsus and all the mechanics there were hardcore dsm guys. they all had eclipses and galant vr4's and shit. one guy had an early mirage with a 4g63turbo in it. they where fast as hell, don't get me wrong (especially the one guys galant vr4) but they where always broken down with tranny problems.

i heard that the 90-91 eclipse/talon trannies were weaker than 92+ ones. and about the vq vs rb thing, id go with the rb.

you sure that vr4 was stock? stock they run mid 15's, that's what c&d says, unless they are wrong (which they usually are), with 0-60 in 7.3

the other source says they do 0-60 in 6. hmm hard to find good info. these dsm's do look really cheap, any idea what insurance is on them?


edit: screw it, i like nissans too much. lets get back to the rb discussion... sorry for getting off topic. :rofl:

rb people

those vr4's were all VERY far from being stock.

let me tell yo what i have seen .What i heard . the top secret japan used to swap VQ30DETT into Skyline R34 . i was so wondering why they did that for .they said -Nismo seems to be getting a head start on the new car by getting to know the new engine .The results are promissing . we can see the improvements of the V6 even on a paper--a lower hight and a shorter length . with those differences , the ceter of gravity is shifted lower and toward the core of the car , reducing polar inertia , and the most importantly , lap times . in addtion ,Nismo reports that the VQ platform loses little power to friction , has highly efficient combustion and is more durable than the RB . Nissan fits its supercar with an AWD layout , which is a dream on the streets , moutain passes , and the circuit . In the upper echelons of tuning , however , AWD turns from an asset into liability . An AWD configuration has lots of extra parts to break- twice as many axles , for instance .

I'm not saying that the VQ30DEtt is better than the RB , I'm just sharing with you guys some of the informations that i know .

heythanks

So I was wondering if you were actually smart or just parroting Superstreet.


Good work with the plaugarism buddy. that exact same line is in the article in superstreet.

lol. You just walked into a library to finish a discussion that took place two years ago... They left like a long time ago...

BTW, plaigurism isn't cool.

It's plagiarism
