alrite guys...*DAYM U GUYS GET ME FIRED UP GOOD* wow, i just got a sweet 90 240sx from a friend for $1000 last week and its in great shape...
now!, i've been reading around from post and web sites and stuff and I'm very excited in doing a RB swap...I have a few questions that i hope u guys can answer me...:
1.) Do I need custom mounts or do i just use the RB mounts? Does it practically drop in?
2.) Will i need a custome intake manifold like unstable-hybrid.com?
3.) I will only use the Rb tranny right?
4.) What are the advantages of the Rb20det over the rb25det?
The reason I ask is that i can find a Rb20 front clip for $1500 and Rb25 for $3000 and its double the cost and was wondering if the rb20 has as much potential as the Rb25...
this is for now...plz get back to me as you guys are driving me crazy!:flash:

1. Your will need custom mounts to fit the RB into a 240SX chassis (untable-hybrids said that they will be releasing those custom mounts to the public for sale for the people that want to do the RB swap into a 240)
2. :confused:
3. Yes you will use the RB tranny
4. I don't think there are really any advantages to the RB20DET over the RB25DET. Both of these motors have a crazy amount of potential. The RB25DET will probably be able to be modified to those higher HP numbers quicker than the RB20DET just because of the higher displacement of the RB25.

answer
1) depends you can get custom mounts also depends on which rb youre going with rb20 i think has the exact angle on the mounts and the engine has the sr the 25 and 26 are tottally different angles so youll need custom mounts. no way will it be a direct drop in. you dont need to go to unstable to buy the mounts just need to know basic geometry and know of a good machine shop in your area
2) you can have a custom one made but i think jun offers one that will work i think dont remember if it will or not
3) yes you will need to the 240 tranny maximum treshold is around 350 400 hp you can use it if you want but i wouldnt take the risk
4) jspec is right about the advantages, also the rb25 is a newer engine campared to the 20 aftermarket support esp. will be the hardest part.
finally any RB series engine has potential strong as hell bottom end also i dont trust unstable they want to much for then engine some arent even front clips just the engine so you could be missing some important wires also there info about torque arent accurate they say the sr has more torque the the rb20 ithats not true the sr has always been know for being a little weak in the torque department . if you got anymore questions im me at Lunitoons43 just dont spam me :finger:

ssup guys...thanks for the replies...just a few things to think about..:
1.) since the rb26dett intake manifold is set up that the intercooler pimping goes straight down, do you think that it could swap with the rb25det or rb20det?
2.) Skyline240: you said that you need a good machine shop in the area, are you saying that you need this even after you have the custom mounts from unstable-hybrids.com? did you do yours yourself?
3.) Skyline240: what exactly did jspec say about the advantages of the rb25 over the rb20?
4.) when did unstable-hybrids say they were gonna release the mounts?
5.) do you guys know where i can get some wiring diagrams for the swap?

oh one last thing skyline240, is your email or watever, what domain is it? is it at hotmail? yahoo? wat? or am i just comfusing myself?

1 im not sure if it will work or not.
2 no if you know of a good machinst and a machin shops and now geometry to can make your own mounts ive never purchased anything though UH
3 he said that there really are no major advanatges therebasically the same engine just one has higher displacment they both have the ability to go in the 500+ range but i was saying it would be easier to get parts for the rb25 then the rb20
4 i dont know and dont care when there going to relaese their mounts
5 if you dont mind calling long distance like i did you can call nismo austrailia and ask to order the rb25 20 26 which ever you one want ask for the manual they each have the wiring diagrams also i have an enlarged copy somewhere ill look for it

hey skyline 240...how sure are you about the rb20 being almost exact geometry as the ka24?
I'm thinking that it would be too much of a hassel to have someone do the exact mounts for me...or is it??? i'm hoping that U-H.com will be selling their kits for under $500...
hell, if the rb20 and the rb25 have the same potentials then i'll just get the rb20...so would ANYONE out there strongly suggest screw the rb20 cus its a waste of time and just go with the rb25 to start out with...cus like i've said, i can find a rb20 for hell of a lot better deal then rb25...
and oh yeah skyline240, if you can find the diagrams that you bought from them, i'll give you some cash for it instead and make it as if we both paid for the same information...email me at tlyang@charter.net if you find it...
so if i was to email you, i would write to Lunitoons43@aol.com right? cus i'm not familar with aol nor have aol...

you dont get what im saying the gemotry is so you can figure out at what angle you have to make the mounts. yeah you can find the rb cheaper but like ive been saying getting aftermarket support would be difficult basically im just repeating what ive been saying the last 3 post. also Lunitoons43 is my instant messenger sn not my email addres you should really read more carefully

I've been researching this swap for some time now. Nice to see it is gaining some popularity. I'm not so sure that custom mounts are required though. If you buy a front clip you can use the front crossmember which will bolt up, then you can use the factory mounts. This is what I will be doing. Have heard once that this will locate the engine a little higher in the car but I haven't seen any more on this.
Our Aussie friends are in hot debate over which rb is the better performer. But general consenus is that the rb25 will give you 1. way better midrange torque and 2.more power with less bolt-on parts. 400hp can be attainable on the stock bottom end.:D

see purchasing a front clip will cost more then just getting the engine i found that out the hard way when i bought the 25 here in the states that only cost me 3300 but when i opted for the 26 and got a front clip that came out to around 6500 not including shipping so when youre a little stapped for cash but he the 26 is well worth it
NIF
07-23-2002, 12:21 PM
right buying the clip will be more expensive. But i believe it would be worth the extra cash as you usually get things such as the crossmember, motor mounts, radiator front suspension/brakes etc. Plus many needed nickle and dime items. So Skyline240 are you swapping in a rb26?

ill try and get some pictures up as soon as i come back home. im currently in the philipines waiting for a new passport since my stuff was stolen so im stuck here till then :( its kinda okay tho i can get more parts anyone say racing hart for 300 bucks?:devil: k well ill answer your question in reverse okay well for the front clip inclund the rb25 tranny and ENTIRE rear End cost me 6500 not including shipping shipping was another 1000 i didnt have to pay for shop time or tolls because my friend owns a shop custom headers and and mounts roughly 500 other misc parts id say around 1500 so total 9500 give or take a margin of a 1000 dollars for error it would of been more ifi bouth the rb25 tranny and rear end serpeate. it took me about a month to do all the work because one i wanted to do a clean install and 2 i was also going to scholl and working at the same time could of done it mabey in about 2 weeks if everything i ordered at the same time and i didnt have to work or school. suprisingly there wasnt much custom work to be done ask anyone in Australia or new zealand the rb into 240 swap is very popular but the 240 is called a 200sx and the rb26 has even been swaped into s13 BUT require a lot of work down there its done a lot and a lot of my info came from my cousin the main problem i had was obtaining a wiring diagram so i could get everything set up now the swaps been done for a while now everything is running pretty smoothly is up in seatle now gettin some work done at my uncles shop hopefully ill be back for the car show in august in san mateo california i wanted to enter it in but dont know if i can make it back in time. the one main problem i had with the swap is traction thats its stiffer susp. helps a bit in the front since more weight is up there so what i did was installed my sound system in clunk heavy inclosures added about another 300 pounds in the back whick actually helped

here's some news guys...tell me what you think...this is a guy from www.japanesemotorsports.com saying this:
We don't actually do the fitting of the engines that we sell, but I beleive the RB25DET requires the A31 Cefiro crossmember. And also the mechanical fan will have to go in favour of twin thermo fans. But that is the limit of my knowledge of the matter.

Ben

Hi everyone,
I am completing the installation of the RB20DET in the R33. Why the RB20DET? Cost and the fact that the car came with only a RB20E. With regard potential, the RB25DET has more potentialk than the RB20DET. With the stock turbo, it is unlikely that you will be able to get past 260hp keeping in mind that the RB25DET starts at 250hp (stock). You must also know that the RB25DET is an extreme gas guzzler, so be warned. Additionally, due to the age of the RB20DET, the large number of R32 GTSt s provide a large number of spare parts....yes, cheap parts.
Please note the following however. The RB20DET also came as a GTS4 which carried some of its modules in the rear of the car. Depending on what you are trying to accomplish, you may need the harness and modules that lead to the rear of the car. The GTS4 RB20DET also carries a different sump to the 2WD model. I have had the trouble changing the 4WD to a 2WD so AVOID the 4WD model.
In Australia, John Penlington of Unique Auto Sports, www.nismo.com.au has been nothing short of amazing. He has been albe to supply anything I needed for my transfer. Don't start without knowing him.
Anyway, if you need anymore info from someone who has spent forever on a RB swap, just holler.

I have had a look at the Venus website and let me just say from experience, you get exactly what you pay for. US$1,000 for a front cut is very cheap. It means that the engine is not in really good shape and may need some work or has done some really high miles and is approaching an overhaul. Mine had 60,000kms on the clock and the car was driven by a friend in Japan before it was cut for shipping. I had a technician inspect the engine searching for coked oil and metal filings. The engine passed with flying colours and cost me the equivalent of US$1,250 without the transmission.
Tuning is a costly undertaking and you would be well guided to spend wisely, not cheaply.:alien:
Yesterday the car was started. Let's just say GRRRRRRRRRRRR!!!!!!!!! I should be getting it this week and hopefully by the weekend it will be on the track for time trials.

tuning is never cheap I should be th first to know as for a living I work on 10 diferent cars each totaling $750,000+ each but I digress. Anyone looking to buy a motor/clip should become well aquainted with the specimine in question for example venus has right now an r-33 clip with an rb25det they only showed one picture I have already asked for more pictures (which I promptlu recieved) plus I asked about the condition of certain items in order to determine true value and total milage (which is approximately 40k) sorry to hear about the bum pan doctor_yaj let us know how it turns out

so far venus-auto is doing great for me...when i got it i noticed the fan was kinda torn and so i called them and they sent me a new one right away and took a week to get it....i really dont even know if i'm gonna use it though cus i'm gonna go with a electric one...
i also got a oil pan from venus today by UPS...so i guess they do take care of you...so far that is...they seem to be pretty prompt and care about your satisfaction...
its true that you get what you pay for but sometimes when you're in college and dont have much, you go for the best thing you can for the money...so far i'm happy with what i got...:)

good to see some prompt service, just had a thought (as I was under my car tinkering) with the oil pan being damaged is the oil pick-up ok is it bent, is the screen torn does the fitting into the pump seem to be tight? I'd hate to see something bad happen :( so even with the complications would you buy from them again?

i really actually haven't taken my old oil pan out yet and checked it out...i will thought before i put the engine in...
well, i never told any of you guys this but before i ordered my engine, i asked venus if there was any front end damage at all and they told me non of them do...so i was very pissed when i got my engine with the sides kinda screwed...errrrr
well, for the money, i guess...hmm, it was a good deal i guess...now if the damm thing doesn't start up next spring i'm gonna regret it all...if i had to buy again, or recommend a friend, i guess...sure, give them a try...cus it was a good deal, and they have decent service :)

I am doing one but my car is already fitted with an RB30E which was only released in Australia and some in New Zealand.
To many people that don't know about the VL Commodore it is surprising to them that General motors fitted a Nissan engine into it,I don't know if the 3 litre Nissan Patrols were released in America around 10 - 15 years ago but they had the same RB30 block in them only in carby form.
I am building a hybrid RB30DE using the head,pistons (same bore size as an RB30) and engine management from an RB25DE powered R33 Skyline which will have the power potential of an RB25DET but heaps more bottom end grunt.
While all the RB series engines are very strong the smaller capacity ones aren't as strong as the bigger engines,for example,the RB25 engine I cannibalised had smaller rods and smaller diameter crankshaft journals than the RB30 engine,the RB20 engine has even smaller components again.
So if anyone wants to build a strong,powerful motor and can get a Nissan Rb30 out of any car even a Patrol,I'd grab it.
The only thing you'd need is a different sump but if you buy an RB25 to use as parts you can use its sump after the louvres on the shallow end are removed as they hit the RB30 crankshaft counterweights,then again it will have to be modified to fit into a Zed anyway

To many people that don't know about the VL Commodore it is surprising to them that General motors fitted a Nissan engine into it,I don't know if the 3 litre Nissan Patrols were released in America around 10 - 15 years ago but they had the same RB30 block in them only in carby form.
I am building a hybrid RB30DE using the head,pistons (same bore size as an RB30) and engine management from an RB25DE powered R33 Skyline which will have the power potential of an RB25DET but heaps more bottom end grunt.
While all the RB series engines are very strong the smaller capacity ones aren't as strong as the bigger engines,for example,the RB25 engine I cannibalised had smaller rods and smaller diameter crankshaft journals than the RB30 engine,the RB20 engine has even smaller components again.
So if anyone wants to build a strong,powerful motor and can get a Nissan Rb30 out of any car even a Patrol,I'd grab it.
The only thing you'd need is a different sump but if you buy an RB25 to use as parts you can use its sump after the louvres on the shallow end are removed as they hit the RB30 crankshaft counterweights,then again it will have to be modified to fit into a Zed anyway
