wich motor?

i dont know if i want to put an sr20det or an rb motor in my 93 240sx. wich would be better performance wise and why? if rb, wich one and why?

If you want a great running 240 that handles well and is the lesser nightmare of the two....go SR20DET. The RB isn't worth the hassle (unless...you go RB25DET or bigger).

BTW I wonder if this question has ever been asked before.

Also BTW it is which....not wich.

yeah unless you go with the rb25 or 26, the sr20 is by all means a better choice, but the modification required on the rb25 is much less then that required on the 26, just a little info if you wanna go that route.

ya rb26 would be the only rb id go with, sr20's are badass and are made for the car so you can't go wrong, plus it will save your wallet a hassle.

read the faqs... then depending on what kind of car you want... choose. Personally, a lighter engine with more torque is desireable. The sr is getting played out now... but nothing's wrong with it. The rb25 is cheaper and will fit better than the 26... with the 26 you are going to need a 25 tranny anyway so it'll be more work. Plus, the 25 is more common in japan since it came in many cars like the gt-s.... so it'll be cheaper than the rb26.

i don't know why i even typed that... it's not even helpful... you could've got that in the faqs.... ah fuk it.

The sr is getting played out now...


:uhoh: :gay:


RB25+>VQ>SR>Dirt>Z31>KA

What? KA is less then Dirt and SR and the Z31? Im going to be racing a friends Z31 soon so well see what is better.

KA's suck.

The sr is getting played out now....
Yeah...the engine that isn't even available/legal in the US is played out....
The rb25 is cheaper and will fit better than the 26....
Physically the RB 26 is the same size as the RB20. The block is virtually the same.

actually the sr is played out foo!!!!!! I wanted one like 4 years ago...now anykid with money buys one....so ill pass. Iv got a pic of a guy with a rb20 in his 240 that i saw over the weekend...i got many other pics too, including one of the cleanest s14's iv ever witnessed with my own eyes. Ill try to get them up on a different thread sometime today or tomorrow.

actually the sr is played out foo!!!!!!
How can an illegal engine that doesn't come in ANY USDM car be played out? It can ONLY be played out in the eyes of the guys suffering from SRenvy. uh...foo!

KA's suck.

Not for drag racing

Not for drag racing

No. They suck.;) Didn't you hear God?
RB25+>VQ>SR>Dirt>Z31>KA

No. They suck.;) Didn't you hear God?

HAHA, ya I heard God he said this tho, Tell Nissan Fanatic to stop switching my words around. It goes KA>SR20DET, at least when the KA is turboed as well.:p

i dont know about you russell but i know my sr is not played out!!
And even if it was, its still a better engine for a well built 240sx. rb20,25, both suck my nuts and as for a rb26dett well save that for a fast show car.

Yeah...the engine that isn't even available/legal in the US is played out....

Physically the RB 26 is the same size as the RB20. The block is virtually the same.

i mentioned the rb25 not the rb20...
and i was talking about tranny + motor

ya so that proposes the rb20 is useless>extra weight not needed

i mentioned the rb25 not the rb20...
and i was talking about tranny + motor
Helloooo! The RB20, RB25, and the RB26 ALL use the same block. Thus they all take up basically the same space....weight is basically the same.
Personally, a lighter engine with more torque is desireable. The sr is getting played out now.... but nothing's wrong with it.This STILL doesn't make sense to me. The lighter engine? Then you post THIS? The RB engines are flat out HUGE!!!
The rb25 is cheaper and will fit better than the 26... with the 26 you are going to need a 25 tranny anyway so it'll be more work.
The RB25 is THE SAME SIZE as the 26. The RB20 tranny is just fine.
Plus, the 25 is more common in japan since it came in many cars like the gt-s.... so it'll be cheaper than the rb26.
Not enough cheaper. Why mess around? If you go big...go REALLY BIG with the RB26.

ya so that proposes the rb20 is useless>extra weight not needed
BINGO!! You win the prize!! The RB20 is WAY over rated. The SR has the same displacement at a fraction of the weight. The 240/180 was made with it in mind.

I have seen many RB20s REMOVED and SRs swapped in. Why would one do the reverse?

How can an illegal engine that doesn't come in ANY USDM car be played out? It can ONLY be played out in the eyes of the guys suffering from SRenvy. uh...foo!

come to nyc and go to a 240 meet, and almost every 240 has a SR in it. its only recently that people are starting to realize the potential of a proper KA-T setup. now the people who are KA-T and people who are building a KA-T project is becoming more = in numbers of the guys here that already have a SR swap.

me with SRenvy? no thanks. i passed that idea over 2 years ago when i boosted my stock and still stock block KA. the KA is fine for me and its doing its job just fine. when i get all my parts sorted out i'll be making close to 300whp on my still stock block KA. the SR is a great engine, i'm not denying about that. but i mean if your KA has low miles on it, then you can save a shit load of money by just turboing what you have. if i didn't buy my 240 with only 46K miles on it i might not have turboed it. but i still turboed the block when it had 75K on the odo, and i have 115K now.

yea sr envey muhahahahaah whats to envy about it?? ANd you say if your going big you might as well go rb26. Well rb26 compared to going rb25...is a couple of grands. So um why even go sr then in the first place according to you right??? sr= "S"hould have bought an "R"b.

i think someone should put i sr or kat in their trunk and put a rb25 in the engine bay then you can have the best of both worlds its the perfect car maybe

Yeah, too many people have the SR I think I'll go around riding an Inferior engines nuts just to be special :gay: The only thing the KA has on the SR is cost (for us mericans anyway) and Displacement... and as much as I love 100mm+ Strokes and Spindley Rods I Couldnt bring myself to pass up the SR.

Its not that the KA isnt capable of the same power as the best tuned SR its just that lately everyone has been Ignoring its weaknesses just to "avoid" the bandwagon **cough Chuki_breath Cough** which I think is as bad if not worse than buying an SR because the JDM mags told you to. but I suppose it is past time the KA got its due...

Perhaps I was harsh with my old Heirachy soo...

RB26>RB25>SR>Dirt>KA>Z31>RB20

Not that I'm one to say one engine is better than the other, but you just said the KA is better than the SR. You said it was cheaper, has more displacement, and can put out the same power. Sounds like you voted for the wrong team on accident.

IMO, the..... JUST CLOSE THIS STUPID THREAD.

And those "spindly" rod you refer to hold 500whp. Doesn't sound to shabby to me for any stock rod.

RB26>RB25>SR>Dirt>KA>Z31>RB20
I concur with that except in the S13. The RBs are just too freaking much engine for the car.....but then I am also referring to drifting. Drag racing?....go RB26.

yeah our spindly weak little forged rods are only good for 550whp damn those rods are weak. thats a higher hp then 99% of us will ever reach.

honestly guys, if one of you can install a rb26 in the same amount of time as a rb25, in identical 240's and video tape it and send it to me, then ill sell you my car for $1. The bets on the table, any takers?

What the hell atre you talking about?? They are basically the same. You need to swap an oil pan and install a different intercooler piping...but BASICALLY the install is as big of a nightmare either way. Neither is a really reasonable option in a 240 unless you really know what you are doing. It ain easy either way. An RB20 is a TOTAL waste of time.

o yea im on the bandwagon....since iv wanted to turbo my ka since i read about chris may in SCC. Damn im a bandwagoner i guess. Just because i think the sr is pointless to waste money on, yea im dumb for budgeting nicely. Go figure. I forgot whats done to your ride RW??

I've been on the bandwagon since september. Shit Tat has been on since april 03 and for 30K. Seems like a pretty reliable bandwagon to me. We need a separate KA section.

for real....i dont get where that even came from. I mean if you actually read the chris may article, i think it would scare most kids to an sr...it took him 3 rebuilds. But hey thats what being a bandwagoner is all about. Feels good i guess.

the reason why he blew 3 engines was because he was a pioneer, and during his time, there wasn't alot of things out for it yet. those 3 engines that he blew were all lessons on how not to build the engine. now that he has it done correctly, i doubt his engine is goin to blow anytime soon.

at least we're not driving civic's with B18's or H22's or the new popular K20 swap. Im glad to have my SR...i would have turboed my KA if it had less miles on it...both great engines

o yea i know that. Im just saying that most kids at the time that read that would probably never get inspired to turbo there ka. I did though hence thats why i dont want an sr. But RW clearly thinks its because i dont want to follow the latest craze....so iv been on the ka wagon since it has been released(may 2002) to the public i guess, its just now that i finally have funds to actually do it. What ever floats his boat though, im aiming to have a running ka-t by summers end. so whatever.....

and they also have a complete how to on the sr engine in the same issue...but yea im not getting an sr so im not a follower clearly.. :screwy:

Build whatever engine you want to because you want to. Who gives a fuck if its bandwagon or not. If you want a civic hatchback with a B16a because you like them, then get it. Don't buy something to be different. You won't like it and you'll be kicking yourself in the ass.

And come on, this bandwagon shit is getting a little old. I got one:

Calling things bandwagon is now a bandwagon. If you do it, you are no longer cool. You will be on the bandwagon.:rolleyes:

i know lol. thats why i said im on the ever so young ka-t bandwagon....except iv just been dreaming about it for 3 years...now its just more popular, so now that i can afford it during the bandwagon times. All in all there is only so many engines to choose from....soon they all will be a bandwagon or should we say just a common thing to do. CASE CLOSED tune the engine you want to tune, why do we fight over all the nissan power houses lol. No matter what choice, you still win.

But RW clearly thinks its because i dont want to follow the latest craze

Yeah, Where would I get that Idea? I mean just because someone says something along those lines in every relevant thread...

go figure

Thats pretty much the point I was trying to make.

just because someone......

IMO, the SR is just as pointless as the RB series if you live in a state where they do visual checks, and you'd like to drive your car legally (paying the clerk a bribe doesnt count as legel lol). I would definatly do the SR swap because its so hard to find a nice, manual, low mileage 240sx around here. But the damn emissions are so strict with all these "save the trees hippies".

I say, earth first, we'll log the other planets later!! :biggrin: (corny, but i heard it when i was having lunch with a friend who is a logger)

Amen...

My statement also coincides with not judging other peoples choices and not degrading their choice.

fanatic is like the guru of automobiles

No I'm not. Far from it.

aaahh...
