heh. well this is strange hearing this from you. i think the only plus would be for show. or to say you have a skyline engine. i'd rather swap something that has more aftermarket parts and support because if something breaks, you can get more responses, faster. a 2 liter inline 6 would rev quite smooth i'd imagine.

Thats it, besides saying u have a skyline engine there is exactly no reason for a rb20det.

DSC

6cyl could give you a smoother higher revving ride than a 4cyl with the same displacement. &nbsp;For those going for less than 600hp though, not much point other than show...unless your rich as hell and just want something that certian low displacement/high cyl characteristic.

since, with effectively the same ammount of work, you could swap in an rb25, with which you would gain both displacement and power, as well as the inherent coolness factor of a "skyline motor", i see no purpose to the rb 20 swap.

this is further enforced by the relative ease of the SR swap (with which you obtain similar stock power numbers), and the fact that you can actually find parts for an sr.

all in all the rb20 swap would be... well... retarded

however, if you are planning on an s15 sr swap (also somewhat stupid, but i don't want to get into that) i would vote to just go a bit more expensive and send your car to unstable and plop the good ol rb25.

just my little opinion

some people say the same thing about the CA though, when comparing it to the SR. but i bet there are more parts and support for the CA in the united states, than the RB. i'd much rather have a CA than the RB.
ah i should have said, it would rev quite smoothly, i think. not smooth.

First off, the fact that the RB motor shares similar design and construction with the CA is an attractive thought. &nbsp;I like the CA motor very much. &nbsp;Next, the idea that six cylinders allows you to have a better bore stroke ratio is important in my decision to endorse swapping in an RB20DET. &nbsp;That means revability and smoothness which I value a lot. &nbsp;I think that's reason enough. &nbsp;

However I would swap in a RB25DET and here's why. &nbsp;It only costs a little more than the RB20DET. It has a better flowing head than the RB20DET as well as the obvious .5 displacement and 9.0 compression ratio. &nbsp;The reason why I like a 9.0 compression ratio is that I am not interested in huge horsepower, rather a balanced power curve. &nbsp;A reasonable metal headgasket can bring down the compression to 8.8 or 8.7.

i think you may be under estimating the cool factor of having a skyline engine. because erkel would be the shit if had a RB in a 240. laura would be all over his knob...

i can see the SR becoming very common as it is now in every magazine on every rack at 7-11. soon it'll be in Home & Garden

not that i dont still want one.

i dont think its pointless, but its certainly not worth the trouble!

they can be built pretty nicely though...rb26 crank and pistons and you have a 2.4L inline 6. massage the ports some, extrude hone the intake manifold, get a new manifold/turbo and GTR FMIC and you'd have a little monster on your hands (with all the other requisite boost-handling parts, of course).

like i said, not pointless (actually pretty fucking cool if you ahve the money to waste), but unless you have the money to waste, not worth it

also in the setup mentioned above you would still only be gaining about 50lb from stock, enough to counteract with battery relocation and carbon fibre hood. if you stepped up to rb25 or got crazy with something like an rb26, you would be upping the ante with weight a little

I think an RB20 would have more total potential for power than a ca or sr. But finding parts for it would be a bitch.

nrcooled

On a scale from 1-10 the cool factor would be a definate 20 ::note the pun...note it:: &nbsp;I would love to see one and talk to whomever installed it but would I want one....hell no. &nbsp;Stick w/ what works is my theory but still cool none the less. &nbsp;As for the CA no thanks also due to little to no support and the pain of shipping all upgrades from Austraila or elsewhere. &nbsp;The RB and tons of money could=mad phat fun yo but since I don't have tons of money give me the SR and affordable upgrades all day thank you very much <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=''>

max power the sr20 can safely support on a daily driver? &nbsp;600 hp, probably.
the RB26DETT can make over 1000, and i have seen 750 hp examples that are driven every day on public roads.

take a right hand drive 180sx, switch chassis plates with an s13 240, drop in the rb26dett including front axles, transmission, and rear end, and all the electronics.
beef the engine out.
daily driver, 800 or 900 hp, AWD, 2600 pound curb weight, easily.
that thing would run 10's on street tires, and you could still drive it in the rain.

Wouldn't that require some heavy floorpan and chassis (in general) modification? as a side effect, I imagine the shifter would now sit in the middle of the rear passenger seat. Well, or thereabouts.

BRSTYLE240SX

how come nobody talks about the RB28DETT that came in the very very limited Nismo 400? i know it's just a stroked RB26DETT.. but would it be worth it to either get the very limited RB28DETT or to stroke your own RB26DETT?<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>

where did you come up with this crap?

first off you cant just "drop in" an rb26dett into an s13 or s14. it takes new crossmembers for the engine and trans, and you cant use an rb26dett trans, unless you plan to do extensive chassis modifications and a shitload of backyard engineering (i hope you like custom fabricating and welding new strut towers). you'd have to go with the rb25det trans if you were gonna stick with nissan. also, you'd need a new oilpan and a modified sump.

800-900hp is hardly daily drivable in a 2600lb car, and again, getting the car to run the AWD trans will be close to impossible

I'm not sure about that. The RB25 and RB26 blocks are just like the RB20 block, but the bore is slightly larger. That means that they should weight about the same. The RB25 head should not weigh much, if any, more than the RB20 head. The RB26 head MAY be slightly heavier because of individual throttle bodies and head design, but even that shouldn't be a whole lot. Thus, I don't think you would be gaining weight by upping the ante...

hmm... didnt mean to imply it would be a drop in affair, i used the term drop in to include the necessary modifications. &nbsp;Not sure why someone seems to think that would include putting the shifter in the passenger's seat. &nbsp;that modification doesnt make sense to me. &nbsp;The RB25 tranmission isnt capable of handling that much power in stock form, and it is a RWD transmission, not an AWD. &nbsp;
Obviously, modification of the firewall and floor pan are going to be necessary to stick a twin turbo 6 cylinder and AWD drivetrain in place of a 4 cylinder and RWD stock, but its nothing that couldnt be done.
You guys are all so quick so shoot ideas down, but its companies like top secret that actually make cars like these, that give everyone jizz fits. &nbsp;
After I graduate and pay off some loans, I actually plan on building this car. &nbsp;It won't be easy, but neither was sticking an RB26DETT in a supra, sticking a supra TT engine and 6 speed trans in an s13 hatch, or sticking a turbocharged b18 in the back of a delsol to make it RWD. &nbsp;I have seen all of these done. &nbsp;I have seen twin engined eclipses and tiburons. &nbsp;Do you think any of this came easy? &nbsp;It didn't, but it was all unique and it was all faster than balls. &nbsp;
And thats what I'm about.

Ok twenty years later... I like that you have big dreams and it's not that everyone is shooting you down it's just most have no desire to spend that much on a heavily modded car that won't be a daily driver because it won't drive daily.
That car will see more down time than a Taiwanese whore. &nbsp;And most of the members on the board know this fact. &nbsp;I'm not shooting down you dreams it's just stating the facts

hey I know guys with turbocharged crx's that dont daily drive.
its not because they dont make power- its because they dont get the lovin they deserve.
You can bet anytime you are doing a swap of the magnitude I would like to that you are gonna spend a long time sorting out bugs and dealing with problems. &nbsp;But once things start to get sorted... shit..
can you imagine the money you could make street racing?
well, probably never enough to pay off the price of the fabrication, but it would certain be more than just a drop in the bucket. &nbsp;I think the biggest problem would be the Skyline parts all being in Japan, and all the schematics and charts for the drivetrain and control modules being in Japanese. &nbsp;Either have to go there and learn Japanese (not likely) or have it shipped here and translated (expensive.)
oh well, nothing worth having ever came easy.
Besides, by the time I have the money to build this car it would probably be way cooler to have a Ferrari.
RB26DETT vs Ferrari?
hmm... interesting though.

Yeah it has merit in the car it was ment for. In the 240SX it is a more complicated swap that will give you no gain in HP or torque over a SR and for the hassle of swapping in this engine you get no local parts source or much in aftermarket either. Not to mention if you want the big HP you need new enternals, that will be 6 of everything which means more money. But hey it's a skyline engine.

Grumpy

I think I'll jump into this topic, Ok Here it goes.............

I have the RB25DET in my S13 and the motor is great. For power, its like having a KA bottom end and a SR top end. The motor just pulls all the way through the rpm's. I have a stock Turbo (T-3) on it right now and the motor is begging for a bigger one. I would think the RB20 is close in power curve as the RB25.

As for weight, not to sure for numbers but as in handling and stuff. The car drives the same whether it has the KA, SR, or RB. I don't see a difference. And I drive the shit out of my car. (Canyon running and drifting) I have the same shocks and springs on the car since I have owned it and the height of the car hasn't changed. All three motors were in the car at some point in time.

As soon as I finish my friends car (S13 w/ 400 to 450 hp SR) I'll weight both cars and let you know how much of a difference there is.

The swap wasn't that hard, mainly the wring was a pain. I have the shifter in the stock location and if the hood is closed you can not tell there is a RB in there. I will be changing to the RB26 later this year, so I'll see how tight of a fit that motor is. But to make the car all wheel drive would be a pain..... You would have to move the fire wall back about 4 inches and the shifter too. That is because the front drive shaft outputs sit 4 inches forward in the S13. Too much work.....

As for HP, the RB25 will hold up to 600hp with mods. And YES the stock tranny will hold that much. It could be daily driven too. This is done all the time. But the GTS-T that are build are mainly for drifting, so they try to stay around 400HP. One car I know of is making 747HP Rb26 with a RB25 tranny in a GTS-T. Also, my friend (a Girls car) GTR-33 is making about 800 and is daily driven. (in high heels) She has no problem with the car or motor daily driving it, but then again she has a lot of money into it.

Most guys use the N1 RB26DETT crank and stuff when building the RB25DET for Drag racing. Any motor can be made strong enough to handle racing, but how much money do you have......?

As for parts, Motorex stocks some and I am going to start stocking some too. You can get all of the books in English from AUs. So no need for translation.

As soon as my Greddy surge tank and bigger turbo gets in ( Hopefully in 3 weeks), I'll take it to get dynoed and let you guys know. I for sure love the RB25 and would not go back to the SR. Don't get me wrong I love the SR, but just love the way the hp is on the RB. Alot smoother and stronger........

Thats my 2 cents I guess..............................

holy crap... i just read your signature, and I have serious questions to ask you.
first off, it sounds like you are to nissans what jesus was to christianity, which kicks ass.
secondly, I have this car on my walpaper, which is a black 180sx with velocity.isfaster.com on the bottom of the screen. &nbsp;the car is sitting in front of a garage, has a vented hood, gold rims, and multiple banners up the sides.
I have been looking for the name of this body kit for a while but I havent been able to find it. &nbsp;Can you tell me whose car that is, what engine it has, and where he got that phat ass kit and hood for it?
also are the splitters on the kit homemade or what? &nbsp;
if you dont know what im talking about shoot me an email and I can send you a pic of it, my email is [email protected]
sorry to get so far off topic guys, but I just had to know.

Griffon2k

Grumpy,

Thanks for laying it down straight in here. There are a lot of naysayers who say it can't be done, or it's too difficult or too expensive, but for those who are truly into making their car the best it can be, and continue to look for new ways of doing this comes the reward. I have been thinking about doing an RB26DETT swap into an s13 coupe, It won't be into my current s13, (I plan on putting an s15 SR20 into that), but hearing your story gives me confidence that I can accomplish the conversion I am hoping to do. I hope to hear a lot more from you in the forum.

RB24_S14

An RB20 is the best engine for the money. It's a 6cyl and it sounds so sick. I say with the same money you can get a SR20 you can rebuild the RB20 and run 500hp easily. Since SR20's are over priced at $2300+.
