RB26DETT in Z
Just wondering what is the cost invovled in swapping one of these engines in a 240z? What kinda of modifcations will be needed to do this, etc, Because I like the car and I can get a RB26DETT for cheap. It came to me, 240z(light weight) + RB26DETT( bullet-proof-high-horsepower potential engine) + single turbo( ie, T78,T88, T51R Kai BB) = holy [censored], hold on :P
I've seen afew pics of 240Z's with them, but no site so if someone can give me some links to 240Z's with RB's in them please post the link. Thanks :) |

why a single turbo? i don't see an advantage of a single turbo on an rb motor since they're not sequential turbos. you have a turbo per bank of 3, not a smaller turbo spooling the bigger one ------------------------------ '73 240z '99 neon R/T |
Re: RB26DETT in Z
dude, theres a guy here in perth who has done a RB26 conversion. You can contact him on nguyenxcuong@hotmail.com. I havent spoken to the guy personally, but I know he is pretty involved in RB conversions for S30 zeds.
A RB engine in a 240 should kick ass man. What box r u gonna use? a GTR box, or one from a RB25? Also, why a single turbo? I know the 1JZ / 2JZ has sequential turbos that arent a good setup for high power applications, but the RB26DETT (twin turbo) should work good with big power. Plus, wouldnt one massive turbo mean 1980's style turbo lag? Just wondering. Kolts Perth - Western Australia |
Re: RB26DETT in Z
Thanks for the info, if anyone has more to add, please do.
Yes if I were to get a RB26DETT I'd use the GT-R tranny. Well I'd go single because it would probably be cheaper and maybe easier to fit a single than twins. Yes I know upgraded twins has a big power potential. I was looking at the Apex'i Isamu RX6B twin turbo it. Looks like the kit can make 1000HP, with good tuning obviously and internal engine work. But would they fit properly? What about a 2JZ-GTE? It has higher displacement than the RB26DETT. 3.0L vs. 2.6L. Unless you cold get a stroker kit for the RB to up it to 2.7L and 2.8L. And 2JZ-GTE's are supposed to be able to handle alot of power before doing any internal work. Something 800HP with stock pistons is fine. but will be able to fit? |
Re: RB26DETT in Z
uhm... how exactly are you planning on using the GT-R transmission? Are you converting your Z to awd?

Re: RB26DETT in Z
opps, i forgot to reply after i read all those posts on hybridz. a AWD conversion would be too costly probably, so a 5-speed from a r33 gt-s will work.How much power can these trannies hold up to?

Re: RB26DETT in Z
a lot :)

Re: RB26DETT in Z
Im sure a box from a RB25 can take a heap of power, there are some wild GTS-t setups running around.
ZMonkey, what sort of power output will u be looking at, and are you going to build a complete road / track car, or just a drag racer? Kolts Perth - Western Australia |
Re: RB26DETT in Z
If i were to do this i'd like power somewhere between 650 - 750RWHP. I'd like it to be reliable. And yes it would be a road / track car.
BTW, what kind of rear end should i get for a set-up like this? and any other drivetrain parts that are important to upgrade to be able to handle such power. <P ID="edit"><FONT class="small"><EM>Edited by ZMonkey on 12/01/02 07:33 AM.</EM></FONT></P> |
Re: RB26DETT in Z
hope you have deep pockets. you'll need to build up the bottom end, so plan to fork over a lot of money for parts not regularly available in the united states, like pistons, crankshaft, bearings, rocks, etc. What kind of a rear end can reliably handle that sort of power? Ford 9", but I doubt you'd be converting to a live axle. You're also living a pipe dream when you say the following in the same sentence:
"I want it to make 750rwhp, i want it reliable, and I want it to be streetable." You can make it reliable and streetable, or you can make it have 750hp. Pick 1. You realize that you're talking about making 863 hp at the crank with an estimated 15% drive train loss? Let's discuss parts: -rb26dett motor is about 3k -gts-t rwd transmission -1.5k (note, these are just random numbers i'm throwing here because they'll likely be more costly when they're not a combo package) -flywheel and clutch to handle the said power - 1k -injectors and bigger turbos - 3k -haltech system management - 1k look, i haven't even gone through half the items, and parts alone are costing you almost 10k. -rear differential... you could use an r230 from a 300zx tt. $500 used -intercooler - 1k -suspension and brakes to handle this - 3k -custom transmission and motor mounts -custom piping -custom done exhaust -sump, pickup and oilpan to cut and shave from a 200zr/r32 skyline gts -rear stub axle to cv conversion for r230 rear diff -new fuel lines because stock are not big enough to supply fuel -new fuel tank -fuel pump -rollcage -frame rails and chassis stiffening and a lot of other custom work that's not coming to mind right now. See what I mean now? Unless you have deep pockets and plan to do all the work yourself, including building up the engine, this is a very long and tedious project. Especially if you don't know what you're doing ------------------------------ '73 240z '99 neon R/T |
Re: RB26DETT in Z
Thanks for the reply.
Yes I know the cost will be crazy. It was just an idea, because i can get a RB26DETT for fair price, unlike other places. And i like the style of the 240z. Thanks again for all the info. Maybe when I'm out of school(1 more year) I might be able to start this project. |
Re: RB26DETT in Z
Do you know what that AWD 1000HP 240z ran in the 1/4mile?

Re: RB26DETT in Z
yeah ok give us some pictures .......
"-sump, pickup and oilpan to cut and shave from a 200zr/r32 skyline gts" sorry only fits teh RB20DET not the RB26DETT and you'd be nuts to run a substandard haltech on an RB26DETT. im doing a conversion with an RB25DET which is way cheaper and easier (im in australia) i'm going for 300ish RWKWs ..... which is around 600 crank hp.... i know the engine can do it on standard internals with a turbo upgrade, injectors, exhaust, filter, custom plumbing, FMIC, etc and i will be pretty much at the cost of an RB26DETT..... to alll the people that are asking why not keep the twin setup: its proven that twins do produce better spool response (why would nissan spend so much on something that was crap?) but you have to buy 2 turbos, 2 waste gates, 2 AFMs, 2 Filters. If you look at the HKS 2540 Kit it is $5000 for the turbos alone and that was a second hand price ! so put on top of that $1600 for wastegates and $400 for the two filter kits that is around $7000 turbo upgrade ..... or you could go out and buy a T67 hybrid for around $2500 that does the same job and spend the rest on an awesome computer like a motec or an autronic and injectors ... the list could go on .... so for value for money thumbs down to the TT .... not that i wouldnt like them though :) Rusty Datsun x 2 1x Bronx Grey 260Z 2+2 (Soon to be blue) |
Re: RB26DETT in Z
If you're after 700+HP from an RB26DETT, you're looking at $30k USD for the engine package alone. Heck, a Trust 2.7L kit is ~$25KAUD and that's for crank, rods, pistons, spacer.
A nice shiny T88-33 or 34 blower is another ~$10K USD. Have a look at the Japanese Trust/HKS web sites (and the Nismo Catalogue) before getting too attached to a plan as grand as this. I've been in an R32 GT-R with 3 people & the Aircon flat out, and it still shoved you way back in the seat.... So, a stock RB26DETT (RWD) in a S30 is pretty damn serious already, and mark Auxillary's words:- you can have 700HP, or you can have streetable... Not trying to sound nasty, but do you think you could drive a 700HP Z? I know I'd try, but.....[img]/w3timages/icons/smile.gif[/img] You will also want to use an APEXi Power FC at the low-end, or a MoTec M48 Pro to control the thing. The new Haltech E11 might also do the trick, but I haven't had time to form an opinion on it yet (The E6K really isn't sophisticated enough to drive an RB26DETT sweetly). Keep the thoughts/comments flowing, as you never know what might come out of it! Ben Adelaide Sth Australia IZCC#1902 240Z L31ETT L28ET MR30 Skyline FJ20ET DR30 Skyline RS-X |
Re: RB26DETT in Z
also you dont need a ford 9" diff ... asif you would put filthy ford parts in when u could use a skyline or 300Z diff :P

Re: RB26DETT in Z
There is a guy with a 260 and a rb26dett and it is one bad mother. this is the link http://www.geocities.com/stonehac/ and he is also zcar of the month on zcar.com month of may 2002. he's running around 280 rwhp. he has an engine install page as well. I've been thinking about this mod to my 240 but can't scrape together the 6 thousand dollars it costs to even buy this motor.

Re: RB26DETT in Z
Hi All,
I have an RB26DETT 240Z, here is some links to pictures of the car: http://www.240z.org/photopost/showphoto.php?photo=1871 http://www.240z.org/photopost/showphoto.php?photo=1872 http://www.240z.org/photopost/showphoto.php?photo=1873 http://www.240z.org/photopost/showphoto.php?photo=1874 http://www.240z.org/photopost/showphoto.php?photo=1875 http://www.240z.org/photopost/showphoto.php?photo=1876 http://www.240z.org/photopost/showphoto.php?photo=1877 http://www.240z.org/photopost/showphoto.php?photo=1878 http://www.240z.org/photopost/showphoto.php?photo=1866 http://www.240z.org/photopost/showphoto.php?photo=1865 Loki, the 200ZR DOES fit the RB26DETT block, so does any other RB sump! The RB26DETT block is double drilled so the sumps bolt up fine, the problem is that the base of the oil pickup gets in the way and also note that the sump has to be modified to clear the steering rack etc. Twins vs Single turbo, Loki and Kolts, I don't see your argument holding water because a single turbo is just as good if not better that twins (it all depends on the set up and the turbos!) The factory turbos aren't that good since the turbine wheel falls off (delaminates) at boost higher than around 1 bar, they are laggy (non ball-bearing) also. Modern ball-bearing turbos spool up MUCh faster than older generation turbos so there is reduced lag. (non of that 80's stuff!) Also don't you think that if 6 cylinders are feeding one turbo would make it spool up faster that just 3 cylinder per turbo?? Have you ever thought about the nice HEAT generated by the 1st turbo that soaks into the 2nd turbo?? (each to their own opinion but don't dismiss singles!) Ben, you have got to be kidding me in recommending the Apexi Power FC (have you ever tried to tune one?) they are very hard to use and time consuming to tune (ie expensive dyno time) since there is no laptop program available for it outside of Japan. (lots of people think the Power FC is the cream of the crop when it comes to RB26DETT ecu but it is only because the writers for a few popular performance magazines endorses the product since he sells them!) Also did you know that you would also have to run all the factory GTR wiring harness in order to use the Power FC (now how fun would that be!) I am not trying to put anyone down, but just wanted to highlight some issues that were raised/made.

Re: RB26DETT in Z
Have you thought about rotating mass enteria of the turbine or do you have a drag car that you drive flat throttle so you dont care about turbine response ? you get more blade drag etc aswell ... i have read an interview on autospeed with the designer at garret and these ARE some of the reasons Nissan went twin turbo...
<blockquote><font class="small">In reply to:</font><hr> Also don't you think that if 6 cylinders are feeding one turbo would make it spool up faster that just 3 cylinder per turbo?? <hr></blockquote> Well yes if you put 2 big turbos on it will but then you will be able to flow more hp ... [img]/w3timages/icons/crazy.gif[/img] ....but if you put 2 smaller ones on then what ? <blockquote><font class="small">In reply to:</font><hr> The factory turbos aren't that good since the turbine wheel falls off (delaminates) at boost higher than around 1 bar <hr></blockquote> Well since ceramic is lighter than steel they spool quicker and are quieter ... so maybe they are good for people that dont want to run big boost out of them .... they are fine at 10 -12psi for ages from what i have heard..... <blockquote><font class="small">In reply to:</font><hr> Have you ever thought about the nice HEAT generated by the 1st turbo that soaks into the 2nd turbo?? <hr></blockquote> Is that any better than having one turbo soak all the heat ?

Re: RB26DETT in Z
Agreed on the PowerFC front. I was referring to the fact that if you want the closest thing to plug-n-play in the aftermarket then that is it.
Personally I wouldn't even try to run one, I'd be using an Autronic SM2 or Motec M48 Pro, hence the recommendation as 'low-end' [img]/w3timages/icons/smile.gif[/img] Out of interest, what are you planning on using in your car? If you've got the $$$ to take on an RB26DETT conversion, then you have to factor all of these 'extras' in. I've converted a few engines & fitted aftermarket turbos & EFI to. The last thing you want to do is underestimate the project. We have modified an RB25DE sump in the way you describe to fit that into my dads '73 - the same was done to the FJ20 that's in his 510. 'L' series owners are just lucky that all the different sumps are available from various models & the only thing you have to do is modify the pickup & dipstick. One day we'll see what twins are like on my 3-litre L-block.... Ben Adelaide Sth Australia IZCC#1902 240Z L31ETT L28ET MR30 Skyline FJ20ET DR30 Skyline RS-X |
Re: RB26DETT in Z
Hi All,
Loki, since you seem to be a technical expert, I will not try and challenge your words, if you believe that the factory RB26DETT turbos are a work of art (over modern ball bearing turbos) then you can keep them (and I will sell you my spare factory turbos when you break yours!) Isn't it better to have two turbos than one for heat soak??? Well you can keep your twins here too, my thoughs were with getting more space under the bonnet (hood) for cool air flow. Also, have you ever noticed that the front turbo's exhaust housing is right next to the rear turbo's compressor housing??? (funny that! I wonder if the heat has any effect to the rear turbo?) At the end of the day, I can't hold it against you if you love the factory twins so much, I will keep my single Garrett turbo on and will be happy with it regardless of all else that may be said about singles. Ben, I am using an Autronic SM2 ecu. RB26DETT '73 240Z L26 + E88 '77 260Z http://www.240z.org/photopost/showphoto.php?photo=1872 |
Re: RB26DETT in Z
hey i didnt say that factory twins are a work of art ... but u said they were crap ... and all i was saying is they are not that [censored] if you dont want to run heaps of boost ... they are quiet and responisive ... i am putting a singe T67hybrid on my car when the time comes ...
