need opinions on rb 25 and 26
wich should i buy an rb 25 or 26, i just have enough for a 26 but if i got a 25 id have money left over, how much custom mounting would be necessary, any info about installation like if its just an insane amount easier for 25 or its the same and wat would i have to get for it to sit right in an 89 290sx

Its not a big secret. I know Batlground has done a couple of RB25s, I would rather have an sr than a rb but do what you like.
fuck an rb, drop a 2jzgte in there.
i actually thought about it but i decided it would prob be to much custom work

a 2jz in a 240, why would anyone do that?
turbo dave did it

It wasn't anything against them Just forgot to post them up...
Do you have a Budget on this build ? Also do you have a HP Goal in mind ?
Seems people like the SR over the RB and now its the 2JZ over it all..lol...
Neither, RBs SUCK. The only RB that i would even think about buying would be an RB20, the 25s an 26s dont impress me. But if i had to choose between an RB20 an a SR20, i would buy an SR20 anyday of the week
get an SR, or do 2JZ, its not as expensive as you think

Mike you make a Good point... With Dave already know what it takes for the 2JZ it could be alot cheaper...
not to mention you can prob hit a mid to low 12's on a stock 2jz dropped in a 240.
sr20det would defintly be cheaper but you already know a 2jz will make you more reliable power and torque and if you care about highway pulls and topspeed you get an extra gear dropping a 6speed 2jz tranny in aswell.
isnt the only difference in the 25 and 26 motor the bore?
i thought they were physically the same but just a bore and of course tranny difference.
sr20det blacktop ftw.Neither, RBs SUCK. The only RB that i would even think about buying would be an RB20, the 25s an 26s dont impress me. But if i had to choose between an RB20 an a SR20, i would buy an SR20 anyday of the week

rbs suck....skylines suck
no quite more differences.
the rb25 is in the gts25t
the rb26 is in the GTR
we charge $4000 to do a 2JZ Conversion in a 240sx, thats labor, mounts, wiring, radiator, and smoe other stuff. Now go buy a Motor with an auto trans for $2500, SAFC for $200
you got everything to make 300whp/300TQ add a boost controller an you can make 350-380.
An SR20 by the time you buy a legit motor set, install, wiring, clutch, injectors, fuel rail, turbo, manifold, exhaust, clutch, etc, youl have about the same money in it. but SR20s will need a upgraded tranny by the time you reach 400whp

I just dont understand why anyone would want a 2jz in a 240
ditto....but some people still like to go there for some reasonNeither, RBs SUCK. The only RB that i would even think about buying would be an RB20, the 25s an 26s dont impress me. But if i had to choose between an RB20 an a SR20, i would buy an SR20 anyday of the week

Here's the last RB25 we did..

so you guys are sayin an rb20 would be better than an rb25???? im not a master at rbs by any meens but shouldnt there be a dramatic difference in power

the difference in price, power, potential, ease of maintanence is better with an SR
go do research on what it takes to BUILD an RB motor, an what it takes to build an SR motor.

o ya i know its way cheaper for an sr because everyone has them so the demand is up but thats also another reason i dont want an sr cus everyone has them, by the way idk if you remember me i came up to your shop lookin to buy your 240 off you, im stephen, by the way whats the difference between a black top and a red top
2002 BMW M3 Carbon Black. Dinan stage 3 Chip, Dinan Intake, Dinan front strut, Dinan short shifter, angel eyes, etc.
black top is the S14 motor, its newer slightly more HP
Red top is the S13 engine
Everyone has them for a reason, cheap, easy to make power, abundance of parts

so you would go with an sr20 over an rb20, cus from jarco they are like the same price
2002 BMW M3 Carbon Black. Dinan stage 3 Chip, Dinan Intake, Dinan front strut, Dinan short shifter, angel eyes, etc.
actually rb20 is cheaper
2002 BMW M3 Carbon Black. Dinan stage 3 Chip, Dinan Intake, Dinan front strut, Dinan short shifter, angel eyes, etc.
yes, parts are MUCH easier to get for an SR20. Try calling nissan an ordering a RB20 Water pump, timing belt or chain, headgasket, etc.
They actually made a NA SR20 in the USA so theeir are counterparts available.
Also, look at Nytryder, he has a MILD build an is taking down Vipers and 500whp mustangs on the HIGHWAY. look at Turbo Daves/Silviadriftrs RHD Silvia running 11.7s with 340whp
it doesnt take much to get an SR to make power, and its easy to build, tons of parts available, easy to replace.
My friend has an RB20 an i watched him wait 6 weeks for a water pump because they were order only from Japan, and i watched him wait for other misc stuff that couldnt be bought locally or nationally

thats a good point you might have just convinced me, how dificult is the swaps i shouldnt have to get custom mounts and such cus its stil a 4cilinder, what all would i have to get to make the swap work

Everyone is doing SR's for a reason. It's cool to want to be different. You just have to be willing to pay and wait
I say get the sr. If you want to be different and get the rb26dett go ahead and just get a gtr, no one has those and you will def. be different.
There are blacktop sr20s that came in s13s.
Shit RB's, SR's, why not go built kat, just as good as the rest of the motors, torques better than SR's. If you go RB, go with the 26, more power and potential in the long run. KA parts are readily available because they came in tons of cars over here. If you need a RB water pump, oil pump, headgakset, anything I can have it all here in a day, you don't have to wait 4 weeks to get it from Japan, just gotta know where to get it.
Built KA-T FTW.

S13 Redtop = early sr20det
S13 Blacktop = late model sr20det
s14 Blacktop = sr20det with variable intake cam
S14 motor makes more power from the factory and I think has a bigger turbo. But the S13 motors have better flowing heads and more potential.

Everyone has their own opinions but it sounds like money could be a concern. The SR20 is a sweet economical way to make great power and they install much easier. Plus the car was designed to hold that motor and the balance of the car will be better. Just my 2 cents but the hassle is way less with the SR also.
I think you oughtta do something cool like a B18, crazy swap, you'd probably be the first.

RB25 is A LOT better swap. They're really easy to tune and parts are really easy to come across if you know where to look. I'd love to see a rb25 s13 rolling around.
AE86 DORIFTO
He'd be the first and that is the gayest swap ever. -1 for you.

ok im just curious, what are you people smoking? sr20 over rb25? and an rb20 over an rb25? WTF?! ok let me drop some knowledge on you.
the rb25 is almost identicle to the rb26 aside from a slightly smaller stroke, and a single turbo as well as no independent throttle bodies and a less agressive cam profile. the rb25det NEO (post 98 model years) used the same head design including same cams as the rb26, boasting a whopping 280hp.
the rb25 (pre 98) with out the NEO system boasts 250 hp stock on a lovely 8lbs of boost.
the going rate for an rb25 right now is around 2500 to 3gs, wait? the going rate for an SR is 2500 to 3gs as well and is an aluminum block 205 hp 4cyl vs an iron block 250hp inline 6?.
I would choose an rb25 over a 26 myelf simply cause you dont have to fab anything but mounts, VS a 26 where you have to scrap the twin turbos, or completely redisgn your steering input, or make the car right hand drive to get everything to clear properly.
yes the wiring is a bitch, but at the same time, ANY engine short of a carbed v8 will have a painfull ammount of wiring except for an sr, which is mostly plug and play aside from a little bit of splicing, but at the same time, you sacrifice max hp capability.
Now SR20s vs Rb25s max power wise.
both egnines can take and produce 400hp on the stock internals, though the rb would be way more reliable in this respect and need fewer upgrades to accomplish this.
injectors, a bigger turbo, and fuel control and 400hp is perfectly capable in either engine, though because of the SR20s aluminum block, a LOT of extra cooling systems would be needed to sustain the power reliably. (SRs are KNOWN for having cooling issues).
to get either of these engines in a 240sx, your going to need exh, a radiator (if you dont want to have overheating issues in stop and go traffic), wiring, intercooler piping, an intercooler, and a BOV. in both cases youd be gaining a bit more power simply from the intercooler and exh alone. in the case of the sr20, youd be gaining about 10% power. same with the rb25.
so SR20 in 240sx = 225hp with those listed parts (still not even close to an rb25 stock rated power)
rb25 in 240sx = 275 hp (now we are talking)
personally an rb26 is nice, but way to expensive at double the price of an rb25, for the price of an rb26 you could have the rb25 in the car, running driving, with about 400hp.
once again, 2JZ over both.

2jz price, is just as expensive as an rb26, and putting a yota motor in a nissan? sacriledge!
