I'm with this guy. Why no option to just stick with the KA?

goofynick6

Because when you up the boost and blow the ka, you get greedy and end up building the whole thing, and the money and time spent doing it could go toward a newer engine that was built for boost and would withstand more than 10-12 psi safely.

I gave a kid with an RB the thubs down last night.

200lbs extra in front...

KA is best for touge and drift. Instant power and easy to control.

Var

almost everyone in this thread keeps reffering to RB.. WHICH ONE? only a few have been specific about which rb engine they are talking about. which rb engine adds 200 pounds to the front? the poll reads


RB or SR?

which rb?

Hi

They all add 200lbs. RB, although compact, is still a 6 banger, and therefore bigger and heavier.

RB20 and RB25 are nothing special really. The RB26 has all the extra bottom end strengthening that made the RB series so popular. I guess you can say the RB20 and RB25 are just riding on the wave of the RB26's popularity.

rps13 SR

2jz is better...

Chernobyl

... or L28et That's a good Nissan inline 6.

180hp non-intercooled. Not bad for 1981!

goofynick6

Yet again, the perfect example of the guy who starts rumors and spreads bad information because he obviously hasn't read anything.

No, not all RB's add 200, and adding 200 depends on if you had auto or manual before hand. The rb20 is a lot lighter than the rb25 because the transmission is like the sr's and ka's, and is smaller than the rb25's.

On top of that, 90% of guys who add these engines place them properly, and notice no ill-effects on their handling of their car; the power makes up for the extra weight and then some.

Why give someone thumbs down because they're different and probably will make more power with less mods than you? You seem like a dick; you should be giving him thumbs up for being different and having an engine that doesn't sound like ass...

and oh yeah.."rb20 and rb25 are nothing special"

Is that why people have made 600rwhp on stock internal rb25's? And 500rwhp on stock internal rb20's? And that's w/o a bunch of headwork and stuff like the sr guys do that make that much on stock internals.

Sorry man, but stick to what you know from now on..

Nick

goofynick6

Yeah, and we all know how much touge driving we do here in the states...

nissantuner22

I'm torn between the 2 myself. Its very tempting to get an RB20DET, as my car is mostly a daily driver that gets "sprited driving" from point A to B. The only thing really stopping me from the RB swap though is the parts supply. With an SR20 I can get whatever I want, with an RB, its kind of intimadating. What if something craps out on the car? than i gotta wait for parts. ugh.

anyone daily driving an RB now and can comment on its reliability and drivability?

Wow! Thats alot of power...

goofynick6

RB parts are becoming very common now, and they share parts with the non-turbo 300zx. Sparkplugs, fuel filter, coilpacks, clutch, etc. Other parts like belts you just size them up at the local advanced auto or napa and get them. Waterpumps and gaskets you can order from a dozen online places that carry them now and they usually have them in stock. If you're looking for something under 400whp, the RB20det is a very easy, effective, great sounding/performing engine that is usually cheaper than the SR.

Wow goofynick, you actually needed 4 posts to "prove" your point? Blah Blah.

I gave the rb25 kid the thumbs down because he was attracting attention to me on a public street in the middle of the night. I don't street race and I don't want any cops thinking that I do. Besides, I've met him before and he's a tool.

And no, RB20 and RB25 are still nothing special. Saying they can run X amount of horsepower with stock internals really doesn't prove anything. L28et can do 400hp on stock internals as well, and that was back in 1981....

You think these engines are god's gift to the automotive world because you aren't used to seeing them every day. Go live in Australia for a few years and you'll get over it really quick.

Pound per pound, the RB will weigh more than a KA. The 200lb figure is a bit high now that I think about it, but I'm sure there is still a 100lb difference or so.

Baka Sama

Does anyone know how much the stock Ka weighs??

Im in the process of doing a Lt1 swap into a s13 and I wanna know whats the diff. in weight gonna be like.

oh and as far as rb20 ,rb25, rb26, vs sr goes..... I still say good ol' NA KA with bolt ons! its fast enough and the money could be spent on other things like suspension/tires/track time/exc.. Whats the use of having a rb26 if you cant drive worth a damn?

Chernobyl

Finally, someone who understands where I'm coming from...

Although stock KA is better than KA w/boltons. Because you don't really feel a difference, IMO.

crazyikimasho

on the reliablity note... my s14 has been RB25det powered since November of 2003. Since then the car has been all over the eastern seaboard to various events and from New York to South Carolina.

The car is very reliable. I do drive in drift events so I know how the car handles. The motor is clearly heavier, but adjustments can be made in suspension to compensate. Not to mention things that can be removed to reduce weight. The car does have a significant amount of oversteer now compared to stock, as the engine is heavier. Overall the car is very fun to drive, I am still running just over stock boost, with stock downpipe, and open cat.

I weighed the car with everything, as the car is loaded (i.e. sunroof, leather), including amps and sub. Without me in it and weighed 3000lbs on the nose. With a decent suspension setup: coilovers, bracing, replacing the 4.36 gear I have now with a 4.08 again, and some small misc stuff the car will be great on the track.

It all depends on what you want, the sound is amazing and the car is super smooth. On the highway its great, just need to get the 4.08 gear back in so that I am not running 3800+ rpm at cruising speeds on the interstate. I like my setup, but its not for everyone.

get a motor that actually belongs to the car.

right on l series are nice. i love how everyone is raping this rb bandwagon. Thank you sport compact car.

Or just someone else who will never have anything other than a KA, and therefore will bash what they don't/can't have.

I never said the RB was god's gift to anyone, but I'd have to say it's better than a KA...yeah, stock KA with bolt ons, and you'd still get beat by an SI.

Ignorance is bliss guys, and most of you are happy as can be. I'm done with this thread..argue all you want, call me any name you want, but when it comes to the street and real life that's where it counts; not this zilvia crap..

You're the one who keeps arguing about some engine you've never even touched. And I'd rather autox a KA over an RB any day. Power isn't everything. For power, I always have my 13B-t... so yea...

Go rub one out or something, and quit whining about "where it counts" Zilvia is not crap, it is the shit. What are you trying to prove, and who are you trying to prove it to?

Baka Sama

#1 your a dumbass

#2 I will never have anything other than a ka so i bash on things i cant/dont have?? please... I am not 16 and i dont work at McDonalds. If I really wanted a SR20 all I'd have to do is pick up the phone and call my friends shop. If you read! (wow theres a thought) I said I was in the process of swaping out the ka for a lt1. Man I cant wait to drop that v8.

#3 When I said a ka w/ bolt ons i was refering to drifting. The 2k you would spend on a jdm engine you DONT NEED could be spent on better things such as suspension. Why the hell would u street race a stock ka?

Remember to keep those exact words in mind if your ever lucky enough to get spanked by my lt1 240.

Chernobyl

Can't wait to see this LT-1 in a 240... definitely post pics when you're done.

Reverse-flow cooling and huge aftermarket, not a bad choice.

V8 is a more compact design than I6 also.

I like the way you think.

Ghettokracker71

Aries on NICO has a juiced LS-1 in an s14 IIRC

goofynick6

I don't have anything against a KA, or and LT1 or CA18..etc. Anything in a 240 is cool. However, when people just downright bash an RB or anything that isn't the almighty truck engine, then I think that is stupid. I'm open to all engines and setups, and I think everyone should be.

But spreading bad info about something and then giving someone a thumbsdown like that (if it is because of their engine) just sucks.

it's not a truck engine,,, the trucks get sports car engines.

I ran into a dude who plans on swaping a v8 into a 240.
I feel like he is betraying the whole import movement.
It is almost sacriligous.
I wouldnt swap a RB20. RB25det or 26dett, yes.
Putting the bigest motor in your ride is the American way.
But a v8, there is just something fundamentaly wrong with that.
Isn't part of it to smoke V8s every chance you get?
Now your flipping sides?

brianglawson

i was curous, how tourqey does an rb20 feel to those who have one, say compared to an sr....im planning on one for my 240z, i can get one for 1700, and thatll leave me alot of extra cash to make it humm
on the arguement, i like all of em, L series, sr, rb, ca, all except the V8, to me an american v8 just doesnt feel sporty but thats a personal preference... 2jz, is also a great motor, to bad there so expensive
