wow thxs for the great replys. I will def check out the links you guys gave me.

 

A RB26 motor swap sounds cool, but it sure is a lot of hassle and expense to do right. It makes my head hurt just thinking about it. I wouldn't do it unless you have alot of money to spend.. like alot more than $10k. Otherwise SR20det or rb25det makes more sense.

 

I've always wanted to build an RB26.

I think I would build the motor first, then find a car to drop it in. I thought it would be cool to tub out a 510 and drop one in there. I'm sure there would have to be some serious reengineering to make it work though.

 

When looking for an s13 especially i wouldn't buy one online. These are famous for the frame rails being rusted out. S14 are better, but also cost more. I have owned 4 240's now. 3 s14's 1 s13. 2 of which had sr's. 1 of which was a ka, with bolt ons and nitrous. Definatly get one with good frame rails. Other then that im sure you know these cars are hard to find in manual and clean. So you may be doing a manual swap. No biggie as most of the parts are already being swapped, you just need pedal set, slave cylinador, master cylindor. Im glad you did your reaserch and know you need the rb25 tranny. It would be very costly and very hard to do a awd rb26dett trany in any 240. The most reason s14 i owned and i was about to make it a project car but i decided i wanted an evo. I went over all the possibilites, turbo ka, sr20det, rb25, rb26 ect. Know what the easiest and best way was to get the car fast? a LS1. I know you may not be keen on the idea, but its an aluminum block so it actually ways about 60 pounds less then the cast iron ka24 in the 240 stock. Also if you get good mounts, such as hinson they drop the motor lower and makes the center of gravity actually really good. v8 240's are bad ***. LS1's stock will do near 300whp. Parts need for this swap would be driveshaft 300, Complete ls1 with ecu and trans. 4k, headers 1k, for hinson to do the wiring 400, radiator 500. mounts 900 At this point you are just over 7k, and the car would run 11's and handly amazing. the rb's are great motors. AMAZING motors, but unfortunatly we never got them hear, and parts are hard, and very costly to find. LS1 parts are easy, and cheaper. If you take this setup i showed you, geat a good head and cam 2k, and tune it, you can have a 2600 pound non stripped 470+whp 240 that is NA. Can you imagine the torque in that small of a car with that much power. Like i said i was super close to doing it, and i still plan on it one day, just right now i would rather take the almost 20k i have saved in cash for a car and spend it on an evo. Either way your car will be sick, and a ton of fun. good luck, post updates,a nd pictures. Chris, oh feel free to ask me any questions. PS a good place to get nissan motors is jazzproparts.com. I have gotten a couple motors for me and my friends from them. Never a problem, great prices which inlcude shipping, and the 1 time i had an issue(damaged ecu) they replaced it right away, all it took was a digital picture for them to send a new one. Right now they are selling rb26dett's complete for 3400 shipped.

 

V8 in a lightweight car has always worked (just ask Mr. Shelby). I think people don't do it because they are so stuck in a close minded JDM is the best mentality. Personally I think a V8 240 would be a very good drift car. I almost bought a 2nd gen. RX-7 w/ a rebuilt chevy V8 but passed because the body was such a mess and the install wasn't that good.

Evo's are amazing but they are the easy way to go fast ... but what can i say i'm lazy, and I like that new car smell

 

Interesting idea, but I am just not a fan of cross maker swaps. Even though the LS1 swap makes perfect sense (and even more so with FDs since their are so many with blown motors).

To the OP, you toss the term 180 around when I know you know it would be a 240SX. OR are you actually going to buy a RHD car? Would that make it eaiser swapping a RB26DETT in as opposed to a single turbo RB20 or 25?

P.S. There is an "Other Cars" section.

 

Good luck with everything...maybe Wicked MR can chime in, this was his old car.

Ok, well being that my last car was an rb26dett s14 with 520whp (for the people who dont wanna open the link) I will give my opinion.






Well the first thing is make sure u have a ton of time and money to invest cuz this wont be cheap or easy to do right. Here is a decent list of stuff u should be buying when doing this swap right.

motor with rb25 trans
get ready to buy all the small stuff on the motor that will most likely need to get replaced such as coilpacks (mine kept going out), ignitor, plugs. alternator
Powersteering pump modification or rb25 pump with new lines
mount kit with tranny mount and crossmember
driveshaft
custom IC piping with FMIC
custom turbo o2 extensions and downpipe (the steering shaft gets in the way nasty style)
Wiring job
Koyo KA24 radiator custom radiator piping
LSD
suspension
fuel pump
standalone engine management if u plan on modding later
oil pump drive collar fix which requires a little bit of crank work

there are probally some other **** i should mention but as u can see the list gets long. i would buy all the stuff u need to get the car running as good as possible like coilpacks and whatnot cuz when something breaks it will take time to find replacement parts. And honestly unless u plan on pushin numbers over 450 go with something else like a sr20 it would be cheaper and alot easier but if you wanna go big the rb26 is a good choice just be prepared for everything that comes with running a swap like this. if u decide to do it make sure u post a bunch of good pics cuz everyone on here likes to see a good build. heres the old cardomain if u wanna see other pics. http://www.cardomain.com/ride/805997/3

 

rb26dett motor (from r32, about 3500-4000)

i thought that price included the tranny.

Keep us updated on this....this is intresting.

 

the rb26 is a great engine but the parts are going to be expensive. theres a guy near me, well a few, that own 240s w/rb26 in their cars and they are beating hiyabusa's on the freeway. expect to spend alot of money though because of the parts rarity. u have to get ,as some of the members have described above, rb25 transmission and crossmember ( http://mckinneymotorsports.com/products ) i came across that idea b4, but what its worth is well not worth it. if u got a stash of money, then do it. heh heh. if not heres my 240 still in the building stage. its drivable but still needs few other things like bigger turbo, other junks, and a paint job. heh heh. or u can just go to http://members.tripod.com/~grannys/ and find out. scary stuff when a 240sx sounds like a freaking vette next to u. good luck with ur project. oh heres my car in its early stage. https://www.evolutionm.net/forums/sh...hreadid=178092

 

Yea it does but that is the rb26 AWD tranny which is unuseable in the 240 so u gotta get the rb20 or rb25 rwd trans.

 

My next car is going to probbably be a 95+ 240sx with either an sr20 or rb25. I heard the rb26 is a pain in the *** to swap.
I have a friend that will do swaps if anyones interested. He's pretty cheap and he knows what hes doing.pm me if you wanna know more.

 

great project ... but i highly recommend keeping the awd

take a peek at my R14 project -- awd, lhd, rb26 s14

jesus geoff, that thing is going to be a complete monster. I called you guys up a few weeks ago to find out that your producing a full race turbo manifold and intake manifold for the rb26 which is great news. You guys continue to push the envelope

 

thanks for your kind words we are working quite hard, and the exhaust manifold is completely finished being developed and is now in production

the big question i have regarding the intake manifold is whether or not to keep the ITBs. Everything we've seen thus far indicates that the peak power increases certainly exist, but i have never seen anything concrete regarding the change in throttle response

Im going to be doing some back to back testing on my s14 so we should have everything figured out by SEMA. The car just came back from paint and is getting assembled now ill post some pics if you care to see
