Which will it be for you (money no object)?

I would choose for both my S14 that I had and for my 300ZX NA the RB25DET...in the right trim...and w/the right turbo...I could make insane power...since it is just as strong as the RB26DETT that we all know and love...but I wouldnt have the clearance issues that the RB26 would have since the turbos hit the steering column in both cars...well at least in the Z32 it would...not positive about the S14...but both can be done...but I like big single turbo for highway pulling!

Oh and b4 you ask what the SR20VET is...it's a turbocharged engine that the will use in the X-Trail GT...see link to Engine Family below...

http://www.freshalloy.com/site/features/tech/engines/home.shtml

Im thinking the S15 SR20...is that the SR20vet? I thought the S15 had an SR20DET variable Valve timing. O well I woul dlike an SR20 with #s like that.:D

S15 has 250HP...the SR20VET is what comes in the XTrail...has 280hp...w/variable valve timing and lift. Different

hmmm i voted for SR before i even read the post. now that i've read it. the RB all the way. who wouldn't want a skyline powered 240?

I retracked my privous stament. I would like the S15 SR20DET...Just because it will be enough. Not overly big...shit I can beat N/A Supras with my KA. http://www.automotiveforums.com/vbulletin/showthread.php?threadid=65764

S14 Sr20det intake pulleys custom intercooler piping nice effecient intercooler. T3/t4 turbo with ceramic blades and ball bearings....and spit it all out some Apexi GTSpec piping...... thats what I would like if I had money ...... If I had money and it were no object Id get a skyline if I wanted the skyline engine.... enough said

I chose the RB25DET, cuz that is what is going in this winter into my 89 240. And I am going to F**K up the SR20 Lovers around my town. The only downfall for the RB25 compaired to the SR20 is that parts are a little harder to find.

Hehehe...good stuff man...RB25DET rox the house!

its all about the KA24DET cause its eaiser to replace a blown KA motor than a SR20DET...

BY THE WAY!

the rb20det has 220hp stock! NOT 200...and i dont think anyone in the minds would even think about getting the R31 POS 190 hp or so engine...so i'm picking the rb20det overall cus its cheaper than the sr20det, yet just as great and its what i'm putting in my 240sx...and to some of you guys can say all you want about how the rb20det is a waste of time, but i bet you guys didn't get your clip for $1000...

ok, i'm a bit lost, is this engines specifically placed into a 240? or is it the engine all by itself, cuz it seems everyone is going for the engine after it fits in the 240

(THIS IS MONEY NO PROBLEM...)
by far i go with the RB26DETT, as long as it's in an R32 or a R34, after a couple extra G's, u can have 1000hp in no time

but as for engines to go into a 180, i'd have to go with the SR out of a S15, and grab the strawberry face with it. lighter engine than the RB series, plenty of power, and still gives you a lot of room under the hood for the add-ons.

but money is a problem so RB20 all the way, I got dohc beat, how bout an RB25 for $500, came with ECU, tranny, and entire wireharness...........but i gave that engine away :) and i'm not joking

This is an engine faceoff in terms of which engine would you like in your 240SX for maximum performance

People are crazy about the SR but the RB's will blow them out of the water...too bad they dont know better :mad:

BTW...to get a RB26DETT to 1000HP is gonna take a bit more then a "couple" g's...more like several

ok, when i said said a couple G's, that was going along with the "Money is no issue" thing. i know of a guy who bought a R33 with alittle more than 1000hp in it for 4 million yen, which at the time was around $37,000. which was about the price of a altezza in the states, if i'm not mistaken. and that to me sounds pretty cheap considering it costs somewhere around $80,000 for a R34 in the states, stock.

i totally agree with u that the RB series are better than the SR. but the fact that it's going into a 180/silvia engine bay, it doesn't leave much room in there for u to add modifications like u can with an SR. that's just how i feel on the situation, not trying to sound like a prick or anything alright

Never said you were a prick or anything...

I've seen an RB25DET in an S14 w/upgraded turbo and FMIC and other goodies...so I dont know what this space issue is your speak of...probably have more space issues w/the RB26DETT...

An R34 GT-R will run you 89k

Altezza's dont come here...they are called IS300's and the sticker for around 31k

(Not to sound like a prick...I just like correct info)

:D

I voted for turbo KA :cool:

I could not vote cuz the engine i want is not one of the options. I would choose the RB30DET. The RB30DET is a hybrid engine. It is a hybrid of the RB26DE or RB25DEand the RB30E (Australia only engine, I beleive GM used this engine in one of their Australian Holden Cars). The RB30DET is a twin cam single turbo engine producing over 476 hp and who knows how much torque. I beleive some Australian companies sell this engine for $11,000 USD but you can build it yourself.

i never knew they made an N/A version on the RB26, i thought it always came twin turbo stock, and i never heard of an RB30 either.....how old is the RB30E???

Here are my thoughts on this topic:
-The Q45 engine JUST WON'T FIT.
-For that matter neither will the 300ZX engine.
-The RB25DET is 275 horsepower stock, but it has less room for improvement than the RB26.
-The RB26DETT is 277 horsepower stock, but the twin turbos have a hard time fitting under the hood of a 240SX.
-The SR20VET is 278 horsepower stock, ~AND~ it is much lighter. The only problem with this engine is whether or not you could get a transmission for this little boy, considering it's on the 2002 X-Trail. The problem getting this engine is for two, if not more reasons.
1) It's a brand new engine with only one platform of transmission available (unless I'm mistaken and the transmission for the DET is compatible with the VET)
2) It's a truck transmission, which isn't the size, length, etc. of transmission the Silvia/240SX uses.
The RB25 is about 9-11k after installation to swap into a 240, and the RB26 is much more because of major modifications, plus it's pretty hard to find a shop. The SR20 swap is about 4000 after installation and it's more practiced (meaning more people know how), plus the mounts are right under your hood already (no extra fees like with the skyline engine).
If anyone finds a way to plop an SR20VET in a 240SX could you post the price, how, and where (or just as many details as possible)?
Also, could someone post where a good shop in Northeast Ohio (or just Ohio period).

Thanks!!

There is no NA version of the the rb26... i wrote rb26de because i beleive that the twin turbo is removed from the rb26 before building the rb30det. It then uses some sort of bigger single turbo, im not sure.

I beleive the RB30DE came out in the early 90's in an Australian GM car. I saw a dyno reading of an RB30DET hybrid engine and it read 476 hp without any other work! I will get all of the details for you and post it.

ok

The rb30det comes in 3 forms: rb20/30 rb25/30 and rb25/30.
The rb30det uses the block from an rb30 single cam. The rb30det can produce 6-800hp at low revs. The hybrid can be made with an rb25 or rb26 without work on the block or the head. Building an rb20/30 requires extensive modifications to the block and the head to get it to fit.

Australian Rb30 engines:

Rb30et
Turbo 3 liter engine used in the 86-88 Holden Commodore. It easily produces 400 hp, its bore and stroke is 86x86, and its compression is 8.5:1

Rb30e
The Rb30e was also featured in the 86-88 Holden Commodore as well as the Australian R31 Skyline. Obviously it has the same bore and stroke and compression as the turbo model of this engine.

Rb30de
This engine is a race engine and it was not in production.

I have also attatched a dyno reading of the rb30det. 467HP @ 6000 rmp and 456 ft lbs at 4500... wow!

Three more engines that should be included in this discussion are the Rb22, Rb23, and Rb24. All three of these engines are based on the Rb20. The Rb24 uses Rb26 crank and rods and80 or 82 mm pistons. The Rb23 uses Rb25 crank and pistons. The Rb22 uses stock rods and bored pistons.

Well if money was no object then I would want exactly what duy was using......

just replying to someones statement earlier that the 300ZX VG30DETT won't fit in a 240SX. this isn't true. i've seen it done before, and if you go to the unstable hybrids webpage, they have completed (or are close to completing) a project 240SX with VG30DETT. of course it takes a bit of custom fabrication (well, more then a bit, but you get my drift) and might cost a bit more, but then so does every RB engine. anywho, if money were no option then my obvious choice would have to be Godzilla (RB26DETT), but of course money is an issue, so i'd most likely go for either an RB20DET or a black-top SR20DET out of an S14. RB20 has more power then an S13 SR (the most common SR) and is about the same price if not a squinch more. but of course, with that comes the compromise that parts would be ultimatley harder to find. the S14 black-top offers more power then the S13 as well, but is also more expensive. but, of course, the parts are easy as hell to find. once my pulsar (CA16DE) dies (soon i hope), i'm going into the market for a Kouki S14 or S13 coupe, and these will be my two choices for the engine.

anyone who would'nt want to alter their almost perfect weight distribution for a track car, for a quarter mile car yea rb would be a nice motor, but not for runs on the scca

it actually doesn't throw is off THAT badly. an RB powered S13 is a friggin unstoppable drift machine, that's for sure.

what about a qr25de from an altima or ser? Maybe if we could put sr20 rods in this engine (i read in scc that it shouldnt take too much custom work) and even a turbo, it would be a killer engine. The engine has good airflow, but it isnt good at high revs (thats why the idea of using sr20 rods came up.) The engine also respnds well to mods, has 180hp stock, and a lot of power can be acheived through simple bolt ons. The engine also weighs 13% less than the sr and 20% less than the ka and it has more displacement than both! The engine is also sold in cars in the american market, so getting service and parts for this engine wouldnt be too hard. This engine was designed to replace the sr20de and ka24, so im sure nissan considered the qr superior to this. I dont think i would mind having a qr with sr20 rods, a few bolt ons, and a turbo in a 240sx.

nevermind, i didnt realize that the qr is fwd. will a rwd sr20 tranny work with this engine?

oh

Guys, beside of big tuning shops like Signal or JWT, I probably have invested more money into SR20 than anybody else in the US. I blew my engine many times while racing, and finally stroking it to SR22. But still I think if I had to do it all over again I would choose RB26DETT.

There is no comparing SR to RB, take it from someone who has done almost everything there is to done to it.

Three is no other engine like RB26DETT.

JR

I voted for the SR20DET (S13), since I'm buying a '91 240sx pretty soon, it's a good choice, direct bolt in, mass amount of parts from almost any company you can think of. Any SR motor is a good realistic choice. If I was Bill Gates and money didn't matter, I would love to see a S13 Silvia w/a RB26DETT swap, I don't know if it would fit, but if it did, you could race anything you wanted.

WOW this thread was DEAD for 2 months WTH:p :p

money being no object, i'd get a awd sr20det from a gti-r put into a super hicas s13, AND a rb25det-powered s13. can't lose by having one car with GI-Joe kung-fu-style grip and another capable of drifting and dragging very well. or how about a 3rd car with a vq35dett made almost entirely out of titanium! :D

gawd i wish i wasn't broke.

what he said. :D

The last one is far too big- won't fit, the RB26DETT is a great engine but would have a hard time with single turbo's, the RB20 is too heavy/underpowered, the stock 2.4 is pretty weak, the SR20DE needs it's friend Mr Turbo etc...........


It comes down to the SR20DET and RB25DET (Or RB26 if you can get it to fit)- if the strip is your thing- use the RB- if you like drift/any track racing- go SR20DET

RB's are good for drifting too, if you have the money. more power standard, and not much more weight.

also, the VK will fit, with ALOT of custom fab. (hell, if someone can make a US V8 fit, then a Nissan V8 should slide in easier technically.)

I beg the differ about KA engines being weak. Everyday I find more dyno charts of KA's on stock internals laying down way more HP then a SR with samilar money spent on mods and setup.
Time to kill some myths about the KA

hell it isn't a truck motor either......that engine was out WAY before it was used in trucks. The E model's head flows more air then the DE model from what I hear also. They make 300hp carbed NA KA race engines.....
I see lots of KA guys running a T3/T4 turbo, exhaust, intercooler, boost controller, injectors, computer putting down 350-400rwhp. I've heard of a KA running over 400hp on stock internals. I've also heard of a KA with forged pistons running 500+rwhp with a shot of NOS and a big turbo. This engine has decent torque for an import engine and hauls ass with a turbo on it. All depends on what kinda engine you use, but I see lots of 240 newbies just swapping in a SR cause the KA is "weak" and that being the only reason..... as I said before take 3k u spend on a SR swap then take 1.2k u spend on a KA-T and you will make more power on the KA-T.

And that KA-T setup is a crappy one, hacked MAF, stock SR injectors, no intercooler, no extra tuning......and it lays down more power. So much room for improvement and so much potential. I think the KA and SR are about equal, if not giving a tiny bit edge to a SR as far as strength is conerned....... not big enough of a difference to compensate for the money on swapping the engine.

The stock engine kicks ass. Take your money, turbo that......get more performance for less money.....and you will be even more satisfied.....WIN WIN situation

I just had to go with the SR20DET classic silvia engine no doubt!

If the KA's TRANNY and VALVE COVERS and OIL PANS and EVERYTHING ELSE and ALL THE POSITION SWITCHES werent LEAKING@!!! then maybe we would thinking about keeping that PIECE OF SHIT !

rb25det all the way

just remeber, that POS will be a lot easier to fix...... and when all that and more goes wrong on your RB it will be a hell of a lot worse getting ti fixed...... If you like RB's.... be prepared to have your car sitting for weeks at a time sporadically........ its not a US engine, its not an engine designed for this car.......

I mean who here knows in the states where to find a thermostat, various gaskets, WORK ON RB ENGINES, sensors, mounts, various bolts...... if one little thing goes wrong your waiting for weeks to find the part, get the part, ship the part from japan.......

and god help u if your RB tranny goes out..... which it will eventually when u start modifiying for HP. If a part goes bad on your KA you could have it that day.....

hell do you even know what kind of oil filter they use on a RB and if they even sell that series in the states???

the KA isn't that bad of an engine, and it has 2.4L of displacement and good torque... why do people swap out a good engine for something like a grab bag treat when u get your engine thats been sitting for 5 years in a junkyard out in the elements..... and if your going to modify both engines.... the KA can be made into one hell of an engine.... they were racing KA's before RB25's......don't tell me it doesnt have potential....

they have potential...but i just like SR's better. besides, most of the places that sell SR's in North America make sure they only sell the best quality engines, and they clean everything up and make sure it's working good before they even think of selling it. don't just go out and buy the first, cheapest engine you see, because, as with almost everything in life, you get what you pay for.

i'm down with th ka24de(t). no real reason other than thats what i wanna do to my 240. by the way, whats the deal with the ca18det. i'm still looking at it but no one can seem to give any real info on it. is it a bad engine because i saw the supposed "complete swap" on www.jspecauto.com for $899.00 + shipping. is that too low a price for it to be a good engine and does anyone know if this j-specauto is reputible to deal with?

Consider this, 10k for a rb25 and 15k for a rb26.Now put that 10k into a ka and it will be beat the rb 9.9 time out of 10.KAT is the way, and oh by the way, they only have .1 and .2 liters of displacement more, bore and stroke that ka and you got one hell of an engine.My point of view of course.

Ca is not a bad engine..... its pretty good. People tune them up almost to top Sr levels ....... the engine is just a bit older is all.

edit

another good thing about the CA18det is that variations of that engine have been used in the past stateside.... so maintenance parts aren't as bad to get for say a RB or even a SR....

i just have to grab some sack and actually spend the money on it i guess. you really are steppin into the unknown with a purchase like this. i may have found a good price on r32 front clip with the rb20det, but if its not the silver top i wouldn't want it.

whoever keeps voting on this thread without typing a reply as well, STOP! all it does is keeps bringing this super-old thread that all of us have seen a million times back up to the top, and with nothing new to read. if you're going to vote, at least type SOMEthing.

1st whoever says that the Rb swaps cost 10K are not well read into the swaps at all. go to unstable-hybrids website. look at their RB engine and trans mounts that WORK on this swap, ($500). then (this is what i would do) check out the website for the intake manifold so that the intake does not go over the valve cover, ($500). now since the engine is out of the car you can always do the new clutch and flywheel thing so that is up to you, (300-1000). now get an fmic (if went with the hybrid thing) from wherever (300-1000 depending on what you got and from you. found some for 300 on ebay). now piping, find someone with welding, cutting, and manderal bending under their belt and it can be done in a few hours, (400 or so not so sure on this). find someone to custom fab a drive shaft (around 400 or less, again not so sure). oh yeah your engine. depending on what you get and from who.
Rb20- 1280-2200
Rb25- 2250-3000
Rb26- 3000-5000

so doing the math...

5280 is roughly the price for a Rb20 (which i what i am going with.) give or take a few hundred dollars due to the fact that i don't know what the drive shaft will cost, the piping, and what combination of clutch and flywheel i will be getting.

btw the Rb series engines wiegh about 40-70lbs heavier than a Sr. nice coilovers would make the car much more balanced cuz of their adjustability.

actually the RB20 is the cheapest RB engine to install since it's the smallest and more "SR-like" in shape and mounting position etc. when most people refer to "RB swaps costing 8-10 g's" they generally mean RB25 or RB26, both of which cost at LEAST 7.5k american to install correctly.

yeah the RB26DETT costs alot. the RB25 is much cheaper but still pricy depending on who you get it from. there is one guy that actually did the RB26DETT with the AWD system. very sick.

ka24det tweaked with internals and valvetrain work.

BE WARNED!

if this thread get's voted on one more time without the voter making a post as well as voting, i'm locking it.

today is the 18th, and the last post was made on the 16th. therefore, someone had to have voted today without leaving a post for it to be on the front page.

im offended the ka24e sohc isnt a choice of engines

hehe.... j/k. if voting was still happening my votes on the rb25det.

and yes i added the quote of old s13 in my sig for now because i feel the same way he does... i think dorikin might have started a trend for 240 owners :wink: hehe

Word...Im gonna PM you about a lil project...tell me what you think

started a trend? trend's been going on for a long time now, Mike was just the one to put it into words. too bad he turned into an ass and had to be banned. he had some good input and good stance on 240 ownership.

oh, and the OG club?....i dunno about that. i would join, but most of us are barely OG's. sure i've been into 240's for at least 5 years now, and i'm a relative OG compared to most bandwagon hoppers these days, but there are tons of guys in North Amerca (Mike for instance) and Japan who have been Dori OG's from the start.

just think of the Velocity guys, Derek. they've been around the scene for at least 10 years now, and most of them grew up around it.

i'm just saying: watch what you say. maybe OG 240 Club would suit the situation better, since no-one that i know of on this forum is a serious drifter (yet). derek, you don't even own a car yet (no offence). i just think the wording should be a bit different and then it'd be all good. :smile:

As long as there isn't too much custom work involved, I could go for a VK.:bigthumb:

IIRC, Impul makes a stroker kit. Can't remember the displacement. Either it's 5L or 5.5L.

There's also the Keuylian supercharger that boosts Q45s up 450hp @ 7psi.

Notice the AF before the OG....

Only Ryan and Joe Joe really have grown up around the scene

Even Mike had an Integra before his Silvia...

And I liked Mike (old_S13) and talk to him everyday on AIM. Unfortuantely, I tend to agree with his views...

If you'd like to join, please PM me for your # :smile:

Mike may not post here anymore but he lives on at Zilvia.net

fine w/me.. he was a flaming homo.

he doesn't even have a "Zilvia" either...

No, Mike is one of us...trust me, I talk to him on AIM..he doesnt have a "Zilvia" he has a hatch ;)

to bad he decided to be a flaming prick. i like the guy, but he thinks he can run the world and not follow rules. not the way AF, or most of the world for that matter, works.

mynismo has a reason to be mad at Mike. Mike had an unfoundated hatred of mynismo. i can't see a reason why, but he just decided to dislike him for no reason.

Hahaha! Well if money was no problem i would want the RB! But being realistic now! Money is a problem! So I would get the SR I would love to have a RB but that would be too much money into modifications when i can just slip in a SR easily!
