sr20 vs rb25 (potential)

I've almost decided what motor i'm going to go with and i'm leaning more towards a rb25... but there are limited sites that carry rb parts compared to the sr20, is there as much potential with the rb versus the sr20 since there is a lack of aftermarket support.... sr20 parts are everywhere you go! i just get depressed because rb parts are far and few between... someone please boost my confidence
Thanks

your comparing the difference between an I6 and a 4cyl. Both are strong engines but it really isnt a fair comparision. The RB will be more work and harder for parts. The Sr has a lower power potential IMO but parts are easy to get and the install isnt very hard. What are you trying to get out of it, street, track, what?

I am just about to start my rb swap and i have yet to find a performance part i couldnt find. What parts are u lookin for? when all else fails, try ebay. You can find anything on there. Ive picked up a full catback, koyo radiator, clutch, apexi boost controller, HKS manifold, Garrett t3/t4 ball bearing turbo, 550cc injectors. IMO the RB has plenty of aftermarket support, u just have to look for it. If you need anything concerning the swap, contact Mckinney Motor Sports. THey have EVERYTHING u need for the swap

about how much are you estimating it's gonna cost you to do the rb swap lilskyline? Are you doing it yourself?.. if not how much is the guy charging you to put it in

rb is better. thats why its in a skyline. you could get to an argument to the Nth degree i know, but thats the plain truth.

Well its costin me 6k total... i will be doin it myself with the aide of one of my car genious friends in my garage....go to jspecauto.com, they have a guide on how to do it....

WTF???

when did you come back???

I guess 500whp just isn't enough for a 240sx. And besides, .1 and .2 liters make all the difference in the world.:rolleyes:

So... what brings you back to AF Nissan? I havent seen you since the Dorikin days.

lol c'mon, you guys act like i posted a thousand and a half times over here....

i think i went to 5-1000 while you were gone. so what would you trade??? 9,995 mostly insignificant AF posts or Expert Chef Training Lvl. 59?

wow that's a lot more than i anticipated it to be... i was thinking around 5k or so... hmm did you get a custom driveshaft made... how much was that and what else drove up the cost... i think i'd be able to purchase the motor and trans, ecu/harness and all that around 3k....

Ill lay out for u waht i all got and for how much i bought it....you could do it for 5k but it wouldnt exactly be the most amazing runnin car...you need other things for it....

Motor, tranny, ecu, harness ~ 3000
Mounts ~ 600
1 piece driveshaft ~ 500
3" downpipe ~ 200
ACT stage 3 clutch ~ 364
Walbro fuel pump ~ 100
Koyo Radiator ~ 270
Apex'i N1 catback ~ 350
Apexi AVC-R boost controller ~ 400
FMIC ~ 200
piping/cupplings ~ 75

I mean you could do the swap technically without the clutch, fuel pump, radiator, catback, boost controller, intercooler, and intercooler piping....but then i would be worried about blowin up the motor i just spent all that money on...so best bet is to get everything you need before u swap it....or u could have problems....

lol! dont worry man, 9,996 of my posts are insignificant too

wow that's kind of pricey, i guess i really didn't do my homework that well... hmm looks like i'm looking back at the sr20 again, that's a lot cheaper swap to do correct?

dont do the sr20..its becoming as common as the b16 in a civic....do the rb....just wait a little and find deals....like u can pick up nice stuff on ebay

it seems like so much less of a hassle to put the sr20 in there, and it's something i want to do in the near future not wait a lifetime saving to do it, ya know...

lol! dont worry man, 9,996 of my posts are insignificant too


i would for sure choose the expert chef training


and also for sure choose KA-T

I mean, u could do the sr20 swap...thats fine and everything...but if u are lookin at a budget of 5k...u could do the rb swap for that....just dont get an electronic boost controller, get an intercooler from a second gen supra (i got mine from a junkyard for 40 bucks), with the mckinney mounts, u dont have to get the 3 in downpipe made. and if u can get someone who can do ur wiring, ur savin money there instead of sendin it to mckinney and costin urself 350 more bucks....Do waht u want....i just like the rb swap better cuz its more unique and original.....

well i know 3 people are running around here with the sr20, and 2 w/ turboed ka's.... the guys with the ka24 swear up and down that it's the better way to go, along with less expensive, they say that since it's already starting out with a 2.4 it naturally has more torque, and of course the guys with the sr20 guys say that they can't live up to the sr20 in the long run, i don't know what kind of #s the sr20's are putting out but the 2 guys with ka24 are pushing 450 & 485hp

Ok, well there ya go...some of ur friends have sr20's and ur other friends have KAT....so why not go with the rb just for some change...yeah, the KA-t does have the potential of more torque over the sr20 because it is a 2.4...but the rb25 is a I6, 2.5 liter....so taht can put down the same torque numbers as the KA-t.....and u said u dont know the specs on a sr20....well the s13 and s14 models put down about 220hp...and the s15 black top puts down 250hp...the blacktop is more expensive...but if ur gunna do teh sr20 swap id go with that....

maybe i'll just save a little money and go from there, the rb still sounds really nice, just a little out of my price range at the moment

If I was you, I would go SR.

Redtops PUT DOWN about 180 or so i think..not 220

and s14s are around 200 to the ground

the s13 is 205hp and the s14 is 220.....go to jspecauto.com...look at the engine specs.....but i sitll think u should go with the rb swap....where abouts do u live?? if ur close, i could hook u up with a deal with my guy....

the rb still sounds really nice


Thats the only reason Id go with an RB over an SR.

in all reality it will cost you 7 grand to get an RB into a 240SX. and you could get the same HP from an S15 SR20 for 5000 and not have a front heavy vehicle.

Exactly!

Go with the SR, its a win win situation.

Actually if u get the mckinney mounts, the engine is shifted back an inch and it is almost perfectly balanced....I have nothing against teh sr20 swap i just like the rareity of the rb swap....

Shifting that huge hunk of metal 1" makes the car almost prefectly balanced, really? Do you have a link for this? I am very curious, since the weight of the SR should be further back, and lighter with the all alloy block.

The RB weighs about 700lbs, yes?

shifting it back one inch isnt gonna restore the weight distrubution to what it would be with a 500lb SR. Especially since even with the Mckinney mounts the RB is about 4in away from the radiator.

yea it all depends on your money count man. Obvious the rb is going to be more, but then you have something everyone else doesnt. The sr will be cheaper, then you can spend the extra cash you would have spent on the rb for sr power mods or suspension or whatever else you may need.

to be honest, around here iv seen more rb swaps than sr20's. But i know there are more sr20's than rb's around here. lol the first turbo'd 240 i ever saw had an rb20 in it, thats a rare sighting especially to have it as your first turbo'd 240 sighting. THere is one guy around here with an rb25 too. But its mostly dominated by sr people, and there is 1 ka-t running (that i know of) and there's a couple people still sourcing out parts for there setups. So where im at, its pretty balanced "culture" i guess, but the sr is still winning.

yeah around where i am there are no rb swaps at all....everyone has a sr...so its way over played where im at....thats the only reason im so intent on the rb swap cuz i want to be unique....and i dont realy want to contribute to the sr20 swap becoming as common as the b16....

First of all, im not tryin ti start a fight...im sayin that the motor is more balanced than if u use the rb mounts....im not usin the car for drift...i just want a daily driver with a ton of power....and i have a full tein suspension.....

thats to the flywheels, not rwhp...

Who turbos an engine and then worries about displacement?LoL

Next engine I get is either going to be CA or SR. But I will try all of them by the end. I'm kinda leaning CA...

WTF 700lbs?

you might as well put in a Big Block Chevy in there, 700lbs god damn.
Big Block Chevy 700lbs > all

well i aplaud u...not many people do that ca swap either....im just a fan of doin something out of the ordinary

put a 13bT in it ...i think those only weight about 210lbs or so bare block...and it would be cool

What is up with these V8 whores and this forum...yea the 240 is the Swap Slut but jesus. OH MAN V8 THAT BITCH!!...please GTFO....I really want to start a Poll in the off-topic to show that next to noone in here is or ever will be interested in a V8 240. It pretty much defeats the purpose of what an import is all ABOUT!

Thank you monooxide....no one will ever want to put a v8 in a 240...i mean if u really are into taht why put it in the heavy body of a 240?? drop it in a crx...lol....FUCK V8's....I6 is the way to go....

put a 13bT in it ...i think those only weight about 210lbs or so bare block...and it would be cool

That would be cool....but i would chose a lighter body to do taht...like an Ae86...and id put a 20b 3 rotor twin turbo motor in it....

Thank you monooxide....no one will ever want to put a v8 in a 240...i


plenty of people want to and have...

yo in the states a v8 conversion would be the same as doing a SR, CA, RB, VG, VK conversion.. your still swapping in another motor to get more power, so why not get the motor with more power.

who would swap a vg into a 240..i mean really

who would swap a vg into a 240..i mean really

Who would want to swap an RB into a 240SX??? The VG makes more power and the weight is further back.

Ok, u put a v8 in a 240...ill stick with my rb...we can have a race...and see waht "more power of a v8" does....

OOOOkk.....u keep thinkin that...any why are ppl talkin bout v8's now...this thread was originally about some guy askin bout a sr or rb swap...how did v8's come into this....

dunno...I was just repling to your post...


anyways v8 > your RB

anyways v8 > your RB

Not to flame or anything...but get out of the import forums if ur a v8 fanatic....go play with some blowers or superchargers or something....Ill stick with my rb anyday...yet to be beaten by a v8....not sayin they cant....i know they can put down huge hp numbers...but so can an RB....1000hp potential....same as a v8....so just leave the subject alone...dont say v8 > my rb...cuz u dont know my car...

you're a joke. get a job.

this is how it is. if you want the power of an i-6T or TT then do the rb. imo the rb sounds better than the sr. the sr is cheaper but more cliché. if money isn't an issue, then go with the rb since its not as popular as the sr and its from the legendary skyline engine family. you can get just as much power from the rb than you can with the sr, its just a little more expensive with the rb.

as for the V8, it doesn't belong in a 240. it belongs in a truck or impala or chevelle. what DOES belong in a 240? the ca, sr, ka, rb and maybe vg. the 240 isn't a muscle car, its a japanese sports car.

newbie fight! yay

you're a joke. get a job.
