I want to know what kind of engine swap can I do to my 1998 240sx. Is the sr20 a good engine. How much would an engine cost for my 240.
engine swap on 240sx

RB25 Skyline engine if you have the dough. That's for mad powa.
ohhhhhhhhh shittttttttttttt, no you didn't.
please, for the love of god, just learn how to search the internet. there is more info on this question out there than you can possibly comprehend, it's all opinionated, and that's all you'll get here instead of concrete info
www.google.com
the 240sx sucks, and all the engine swaps you can get are weak.. I'd strongly suggest you sell it and buy another car that's faster... the 240sx is a 16 second car in the 1/4 mile, even if you spend the money to swap an engine, it's still gonna be only a mid 14 car, just sell it, it sucks.Originally Posted by chivistamex
240s suck. i want a buick.
Me fucking too.
Swap in a B16.
nwo you're talking jay. exactly what i was thinking when i posted that.
you should put an rb20 in it...
and then kill yourself.

MMMM GNX, I do love the Cyclone too, nothing like a factory turbo pickup that will run 12's stock. SR's a good motor, RB's are good motors, best reccomendation is to jump on a 240sx messageboard and search, you'll just start alot of trouble asking this sort of question on this forum. If you have the money go RB26, or SR20 if you want to drift, or rb25 if you can't afford the 26, or RB20 if you're on a budget and want a swap with 190hp stock. Or build your KA and boost it, we're building 2 now shooting for 800+.
E
KA24E!
Hell yea.
That's my dream car. I wanted to buy one after the g20, but GNX's are like 40k.Ehh one day.
correction.... ANY forum.
Yeah its a dumb question. It wasn't in 94. But today there is the internet. Search it, use it.
Scoop him up while he is still confused and put an rb20 in his car quickly before he knows what hit him.
h22a4....nuff said
Val RIP
Well if he searches the internet he will realize that the rb20 is handsdown the best possible motor you can put in a 98 240sx.
I know this is what you guys are always getting all fired up about, but it seems to me that you can make more power with an RB without working the engine as hard. Am I right? If so, then what are the downfalls . . . weight/agility?
Actually you cant make big power on an RB without massaging the motor. All the pistons in those motors are JUNK, and yes, that includes the mighty RB26. Each has its drawbacks, one way or another.
maybe you missed something, putting an rb20 into anything besides an s12 or maybe a z31 is a complete waste of a good car. you know what even putting an rb20 into an s12 would be wrong, since a redtop botls straight in and makes more power.
actually your wrong, you can make 300whp on an rb25 with a ball valve and a fmic. its not a good idea but you could do it. in fact there was an rb25 making like 700whp and the guy hadnt even touched the motor yet. as for the 26 how dare you say such things. the guts of that bad boy are good to like 600+whp, the turbos arent but everything else is.
"...I'm a thief, I'm a liar, There's my church, I sing in the choir..."
Dammit. Here we go again.
*sigh* hahaha another round in the "I hate 240" match. This is hilarious.
funny coming from a guy with a 4G63
Stock 240sx runs 15.5 at the track in a 1/4mile
Go check up the specs...Car and Driver
I've done 15.4 in my previous 93 240sx with Hicas
I know of a local car with an sr20det with stock t25, fmic, exhaust, and boost controller.
Made 300whp.
Actually you're wrong. Let me know when you wrench on any of the above motors because I've got 3 motors apart, and the pistons with busted ringlands to prove it. I'll post pics if you'd like! 600+whp on a 26 is bullshit power. Whats the big deal about 600+whp when supras make 800whp on the stock motor? What I'm simply telling you is that the pistons are JUNK in the RB motors, and that's not a "claim" its a FACT. The rods are great though. They're nice and short/stubby from the super short stroke, so that part of the motor is fine. Please call some of the tuners in AUS that I work with, and they'll tell you the exact same thing. I'm not talking making power on the stock shit. I already know the 25 can make 300whp on the stock setup, it's been done to death! Infact, Dan just did one a few weeks ago that did that very same thing! It's nothing new. I tune these cars all the time and I know what they're capable of. That's pretty interesting claims on the 25 considering the pistons are cast and are complete junk, so I wanna see this "stock" 25 motor making 700whp, LOL. Lemme guess, all he has is headstuds and a headgasket, right? LOL. The standard pistons will not take the kind of boost levels needed to attain 700whp, I dont care how much fuel you have in it. Please...I love to hear the bullshit claims people make. I wanna see people put up or shut up. As a matter of fact, I'm gonna post a thread on the Skylines forums titled "Stock RB motor good to 700whp/522rwkw?" and see what kind of responses I get from everyone, this should be interesting...

Wow, I'm not sure what the fuck that statement was supposed to indicate, but OK, I'll go with that. I am in NO WAY saying the 4G is superior/inferior. I tune all sorts of cars all the time, and after the amount of time I've put in working on this stuff, I pretty much have gotten a feel for what the thresholds are of most stuff. That's all. Nothing less, nothing more.
This coming from an asshat with a G20....or did you get rid of it to jump on the 240 bandwagon?
George has probably forgotten more knowledge than you know, so just do us all a favor and STFU.

Oh, another bench racer. The internet doesn't harness the truth all the time, so maybe you shouldn't live by it.

wow.....
I think it's pretty wrong to assume that just because a person owns a particular car that they have no knowledge of other cars. We don't own a Honda, but I assure you that we work on them all of the time. This goes for Lexus', BMW, Vipers, Corvettes, NSX's the list goes on and on of cars that we work on and have knowledge of without owning them. Not a personal attack BTW, just a response.
I love these 'I got a 240 and I wanna swap in a xxxxDET, is this good/make me cool?'
Christ, I learned to quit asking tech questions on local boards years ago. Not that nobody knows, but there's no better place to go for tech info than tech specific boards when searching online.
-91 240SX -- CA18 Power...SOLD, now terrorizing the streets of Alabama
i'd like to see a 300whp stock T25 car. that dyno graph would be hilarious. pushing the stock T25 that hard is almost as retarded as an RB20 swap.
I saw the car dyno with my own eyes.....he's not bullshitting, and you know I'm the first to wave the BS flag.
--RIP Leisa. Forever In Our Hearts--
--Val for President 1979-2007--
I think I saw it, too. Didn't I, Chris?
I don't have the graph for that run as my clutch started slipping. But as you saw, plenty of people saw that dyno. The car makes the power smoothly and it doesn't die off or anything.
oK THEN i DID SEE IT.
It was the sexiest dyno ever.
never said it didn't happen, i wanna see the mountainous peak of power before it falls back to 250whp.
very interesting.... something doesn't add up then unless the T25 on your car is magically different or something. i've seen 300whp peaks on T25's, but the little T25 compressor just can't maintain enough air flow at higher revs to keep that power level up there for long. how much boost was run?
I dunno, it really wasnt under all that much strain to be honest. It was right at about 18psi, maybe 19 for a split second. It did it rather easily too. That car is actually detuned, it can make more. Matt, the dyno chart is in the computer over at the shop. You're exactly right, as soon as the clutch started to slip, the boost was turned down. I dont quite remember how much boost it actually left with, but it was still pretty damn stout! On a side note, even my 20g didnt hold all its power all the way to redline, so I would never expect anything even remotely close outta the stock SR turbo. It's like when I tune a car with a big 16g, they make pretty much the same power/power curve as what Matt's car is makes/is capable of making, but it doesn't have a chance in hell of holding it all the way across the board. I undestand what you're saying though.
