Would A Single Turbo RB26DETT Lag Alot??

[SmackedSilly]

I got a question, i've already seen someone swap in an RB25DET into there 240sx.

I know its nearly impossible unless u got mad funds to put a RB26DETT into a 240sx, BUT i have an idea.

Lets say, u make the RB26DETT into one single huge turbo. Will that make it fit then?? becuz i dont see how much bigger a RB26DETT can be from a RB25DET, cuz it only is .1 leters bigger.

And i also heard the RB25DET and RB26DETT use the same engine mounts, is this true??

and as for transmission choice, im thinking that id get a T56 6-Speed, then modify the bell housing, or u can just get the RB25DET's transmission.




In conclusion, my main question is, if u make it a single turbo configureation, will the RB26DETT fit




ps. im making a road racing car (track), and im just running through some ideas. and puting a RB26DETT into a nissan 240sx seems like it will be amazing

[SaintlyCharBoy]

* note this has been disussed on several occasions *

the rb26 will fit, but, it is equipped with an AWD tranny, so unless you are going to convert your car (good luck btw) you'll need the rb25det tranny

the problem with fitting the 26 is the design of the turbo manifold - it hits the steering linkage - as such, most will just run a single, as you mentioned

afaik they use the same mounts

search fro Grumpy - he has an rb25 in his s13, and has a lot of experience with nissan in general

good luck

don't count on it. I don't think it is as much the fact that it is a twin turbo as much as the size of the engine and the engine mounts. Also the RB26dett is a AWD motor and it will take a whole lot of modifications to make it jsut RWD. So I doubt it will be possible without atleast 50,000 dollars, and the twin turbo to a single turbo won't help either way.

The RB26 is no larger then a RB25, it just needs a RB25 tranny and converted to single turbo cause the twin turbos get in the way of the master cylinder or something in that area , can't recall of the top of my head. All that is not exactly a $50,000 problem.

[xLSTONEx]

you wanna bet it won't cost 30,000-50,000. With how rare that engine is and since no one in the US really knows anything about them or have parts or anything for it, it will take a lot of money. Getting a new tranny and putting it on there, replacing all the parts, getting new mounts and make that son of a bitch fit in there is going to be way high in price. No offence but it is going to take an ass load of money.

Yes I would take that bet anyday.

[xLSTONEx]

Good

[ca18guy]

Unstable-Hybrids will install it for $2,600 (not including custom mounts and intake manifold) plus ther price of $5,500 for a R32 front clip. Thats $8,100 well under $30,000 and I doubt motor mounts and misc. parts cost $22,000. Even cheaper if you install yourself.

[SmackedSilly]

Where can u get a premaid Single Turbo Manifold for the RB26DETT


do any of u guys no of any single turbo kits for the rb26dett??



And as you guys were saying for pricing(In Canadian Funds)


1995 240sx = 7,000-10,000
RB26DETT Clip =8,000
Labour ANd Extra Parts = +/- 5000
(i know a mechanic who will give me a deal, family friend)

so for about 20,000 canadian ill have one sick car
THEN i can use the 10,000 left in my account to do extra stuff to the 240 sx


aka, suspension, seats, roll cage, engine upgrades, intercooler, radiator, lsd, trasmision, clutch upgrades



my total investment is gonna be 30,000 canadian

[xLSTONEx]

damn you know one hell of a mechanic, but whatever guys, im not trying to start flames, but where I live its gonna cost that much. Good luck to you, if it works I want to see massive amounts of pictures and vids. peace.

[Dousan_PG]

yeah you can get one in japan: means YOU NEED AN IMPORTER.

ive seen them in magazines and such. its easy to find. but if you were smart, you'd probably go custom.

[SmackedSilly]

would the the pwer upgrade of using one big turbo equal what u get is u use 2 small turbos

like, i see all the supra guys using one huge turbo, and there making like 900hp


does the RB26DETT act the same way??

[Grumpy]

You can run the RB26DETT as a single turbo. It done all the time.. But the swap is expensive due to all the parts needed.. The RB26 and RB25 DO NOT share the same mounts...

[jhapa]

rb26dett is not as rare as people say, it might be rare in the us, but not rare. it came in gtr from r32 and up, for atleast last 12 years, so not that rare. from what i have read, and researched, rb26 will fit in 240, unless going to do rhd conversion, need to convert to single turbo with gts-t(rb25) tranny. it is not to motor that is awd, it is the tranny. so who won the bet.

don't they use the same block?

[jhapa]

you could also import from austrilia, new zealand, etc. there are other importers besides japan, correct me if i'm wrong.

[SmackedSilly]

What would i need to do to strenghten the body of the 240sx to make it handle all that power?????

so the only reason people say its a waste to do a RB26DETT swap is becuz the second turbo is in the way, but if u make it a RB26DET, then u wont have that problem


how bad do u guys think the turbo lag will be if u want a turbo that will make 500hp on 92 octane

[Drifted off road]

ud probably have to get coilovers in the front and stiffen them up to hold all that extra weight. and u might as well get them for the back so its not unbalenced.

[some guy]

my question is why would you want that 0.1 Liter of extra displacement anyway? you can just buy a Skyline GT-T? front clip ($7000) and have Unstable-Hybrids install it for $2,600, then if you have extra money you can buy better turbos, fuel systems and things like that. except for the novelty, i dont see a point of swapping the RB26DETT in a 240. not flaming, just opinion. ;)

[SmackedSilly]

RB26DET has way more potential


also, say i get the RB26dett and make it single turbo
and i use a RB25DET tranny, and a carbon fiber drive shaft, with the actual car be stong enought to handle the torque??

what will i have to do to upgrade the actual car?? roll cage, lsd??
can i leave the axel stock??

Whats the difference between an rb25det and rb26dett that gives the 26 so much more potential? Is the 26 just a stroked 25 or are they totally different?

PS: xLSTONEx, if I remember right unstable-hybrids said 10-15k for an rb26 swap.

[Kitahara]

Are you sure about that? If you're really set on working with an RB engine, I'd suggest you check out skylinesdownunder.co.nz because they have much more information there. You may even retract that statement...

The 25&26 uses a similar block but the stroke is slightly longer. Also, the c/r in the 26 is 8.5:1 instead of 9.0:1. Big deal, you can swap out the pistons. Other than that, there are two key differences. One, the 26 has individual throttle bodies, whereas, the 25 has a single throttle body set up and overhead intake manifold that would have to be swapped for a non-overhead design unless you were to modify your hood skeleton. Itb's vs. single, make of it what you want. Second, while the 25's head flows far better than the 20, the 26 exceeds both with solid lifters. More reliable, but not something to wet your pants over.

ud probably have to get coilovers in the front and stiffen them up to hold all that extra weight. and u might as well get them for the back so its not unbalenced.

The added weight is not substantial. Move your battery to the back, get a FRP hood, and you'll be more than fine. Coilovers, sway bars, and good suspension tuning should do the job.

[SmackedSilly]

how would i modify the body to take all that power

how high can the rb26dett redline be increased safely

whats the widest tires that will go in the back of the 240sx, is there any 18x10's that fit it??

hahahahhaha this is funny. Currently here in socal there are two RB25's in cars running around and I think possibly more. One the cars is right now going through the transformation of RB25 to RB26. You will see this car on the track. Its a 95 S14. I also know of another 95 street S14 getting a RB26 install. Grumpy already spoke up so there is the RB25 S13 as well.
Hell, I can sell you a Rb26DETT clip for around $5-6K. I have seen these engines torn down and put back together a half a dozen times here in socal. There is parts availible for them because of MotoRex. They have to be able to service customers cars somehow and they do sell a decent amount of Skylines.
Remember MotoRex has been in business close to 10 years.

[SmackedSilly]

OK, im planing on getting a 95 240sx once winter is gone, and making it my: daily driver, drag car and road racing car.

I also want to do a RB26DETT swap to it, but im gonna have to convert it to single turbo to make it fit.

My question is, i want my car to be ruffly 550-600rwhp on medium boost, but i dont want to have huge turbo lag.

If possible, id love it to be spooled up befor 3500rpm


what things, and what turbo would i have to get to reach my goal.

and i also want the redline to be 9000rpm

i know, im gonna be spending a lot of money, but hey, im taking a year off from school next year, and ill be working full time, so money isnt really an issue.


i was thinking, a nicely sized ball bearing turbo, and 2.7l stroker kit will help me reduce lag.



ps. i was gonna get a 2003 acura rsx type s, BUT after i went to the races (i dont street race, just happend to be at the coffee shop the meet up at) and saw a 240sx rape a supra, i quickly jumped on the bandwagon, then again, my friends higly modified wrx beat that supra

[SmackedSilly]

how tuff are the RB25DET tranny's??
will it hold my 600-700+ hp goal???

will the RB25DET's shifter fit right into the stock shifter hole???

how many hp do u think the RB25DET tranny can hold???





AND say i wanna keep the heater and A/C?? Is THat Still possible???
i probable wont wanna keep the A/C still, but at least tell me if its still possible to keep the heater??

Lol. Don't you already have a topic open about this? You wanna get smacked silly??? Shame, shame! Please don't make new topics for something you should ask in there... Thanks!

[RacerBoi]

SmackedSilly:
Are you going to do all the work yourself? I'm guessing not considering the questions your asking. All this work is going to be really expensive. I had the same idea as you, take a year of school and build a badass car withall the money. Then after extensive research i realized how much my dream would cost. For all the stuff your talking about i wouldnt be suprised if parts and labor were over 20 grand. I couldn't make 20 grand in a year and still support myself. Just do alot of research, this and many other 240 boards have cool search functions that help alot.

[LOwrestling2001]

keep heater? hahaha.....u'll always have heater....

[SmackedSilly]

RacerBoi:
Im 18 and i still live at home, and i made 13,000 canadian a year while still going to school full time the last 2 years, and i already have 10,000 in the bank, so i think making over 20,000 canadian next year wont be a problem.
And also, i just recently started invensting in the stocks, and i made 1500 is 6 day, (i love nortel net).

LOwrestling2001:
Lol, im a newb, stop the teasing, your lowering my self estem, lol.
but can i still use the a/c???



And i was talking to one of my friends today who was about to get a S14 and do a silvia swap, but instead got a 2002 svt lightning. He told me in the summer when he was planing the swap, he went to a swaping place hear in toronto to get prices, he told me it was 5000 installed for s14 Engine into a 240sx, and 9000 installed for a RB26DETT engine into a 240sx, and the swap place said they did it b4, so supposivly there is a 240sx roming the streats in toronto with a skyline engine. (prices in canadian figures)

i didnt ask my friend more questions cuz hes kinda mad at me, cuz while he was doing his presentation, i asked him a hard question, and he lost marks, lol, my bad
my friend is a really reliable source, and i belive him completelly that the swap is that cheap.





So can someone answer my first question. My question is, i want my car to be ruffly 550-600rwhp on medium boost, but i dont want to have huge turbo lag.If possible, id love it to be spooled up befor 3500rpm. what things, and what turbo would i have to get to reach my goal. and i also want the redline to be 9000rpm.
i was thinking, a nicely sized ball bearing turbo, and 2.7l stroker kit will help me reduce lag.

[RacerBoi]

Im talking USD. $9000 (cad)/$5760 (USD) is a great price for the RB26 swap. Places around here it costs about $15,623 (CAD) for the swap, and thats for a stock engine. Also, your asking alot of RB engine questions when this is a 240 site specializing in the KA, SR, and CA engines. Thats maybe why you aren't getting your questions answered.
www.freshalloy.com has a skyline section and www.240sx.org has a RB section in its forums.
Another tip is to look at sites featuring modified skylines, see what mods they have and what kind of numbers their putting down.

[Mark & Irena]

As the rest of this forum, I'm gonna say it's not feasible. The trans, driveshaft itself is a big problem. You should consider keeping a KA motor and building a KA, or even buying an SR and building the crap out of it to get to where you wanna be. Single turbo would lag a whole bunch. 500rwhp at mid-boost is nearly impossible w/o a t78 turbine, which i don't think you can fit under the hood of an s14 with the brake parts being there and the strut tower being there, and needing an exhaust manifold. Just a turbo itself can cost you up to $3 maybe even $4K. Your manifold will cost you minimally $500. (Talking USD). FMIC is another grand, min. Trans, another grand. Your motor will cost you $8K. You need to buy a car, that's $10K. Chassis improvement, brakes, suspension, take in another $7K. Plus all the electronics you'll need, at least $2K. Add your internals (for a motor that was never legal in the Americas) that you'll need to run your desired horsepower, that's like $5K. You'll spend at least $3K installing all this ****. Add your exhaust, intake, motor mounts, all the other parts, at least $4K. Your project will be at least $40,000.00 US Dollars. Not trying to get your dreams down or anything, but if you can make $20K a year and save every penny for two years, then all props to you, man. The regular world, we have bills, we have necessities, the regular man on this forum, working his way up from suspension and on makes that $20 (some more, lucky you guys), and saves $3K. Pay rent, pay school, buy food, buy gas, pay for insurance, make our car payments, pay our phone bills... Living is expensive.

Dreaming is nice. I'd have that dream too. My dream was more real though... I wanted an RB20. A $1000 motor. I went to a tech school, I can put it in myself. My budget wouldn't be more then $5K for everything, and it can be made possible. My car's worth jack ****, $3K at most, but at least I own it already. But you know what, **** an RB motor. Screw that motor that I don't have now that I'll probably never have. I'd rather have my car handle good, and then work with what I have sitting in that engine bay now, rather then start from scratch, beat my own ass for parts when I need them, customize, take out, put in, blah blah blah...

But if you still want to do this, more power to you. If you do it, then all the power to you.

Here's some links, hope you read my whole post.
