well im sorry to post my questions here, but i just like this forum and comes here the most. but i really love 240 sx and i never wanted anyone to let it down or hated, i just cant stand people saying that 240sx is slow and its a piece of crap. My friends and cousin have a lot of hondas, and they have swap motors like B16 and mostly they have 6 cars of LS-VTEC all hondas and acura. I know LS-VTEC is fast. When i mention about buying a 240sx, they said, dude what are you thinking, its slow and will never catch up on us if we race on the freeway and you'll be left over because you cant even go faster then a DX. It really made me piss off, because i know its not fast with a KA motor. I really want to swap a SR20DET into my 240 for drag racing, because i wanted to beat my bro if i buy a 240sx and fix it up, he has a LS-VTEC fully built on his Special Edition Integra LS. He talks a lot of Sh#t to me that i will never beat him on drag racing. I heard that SR20DET's tranny mess up a lot and its hard to find. I wanted to get a KA motor and put turbo in there and beat the crap out of their LS-VTEC. So can anyone help me to get my 240sx faster if i get one, im getting on Jan or Feb. 2004, i really want Nissan to stand out from HONDAS AND ACURA, i do like honda and acura, but i see too much, they all look the same. Can anyone tell me about the SR20DET?

What i wanna know about the SR20DET is:
1: is it good?
2: what mess up easily the most?
3: is it fast for drag racing?
4: what other info do u have?

What about the KA motor?
1: how do i make it fast?
2: I just want to make it top speed like 140 MPH?

thanks if you can help me, im really dumb about 240sx, but i really like them, can anyone please help me if you own a fast nissan? thank you
 
Bud, I have some good news for ya. First of all, I'm quite sick of Hondas and Acuras as well. Plus I'm a huge Nissan buff.

First of all, those guys' LS-VTEC's only pump bout 220-240 hp at the wheels, that's if their lucky. A stock SR20DET can easily pump that at the wheels. Plus, since the car is rear wheel drive, it will be much quicker off the line due to weight transferring.
And since you like Nissan, I happen to have a little gift for you. Go to www.Nippon-motors.com and search there for an SR20DET. They are located in California and can usually get you a very nice engine for under 3 grand. Then I suggest upgrading the turbo stuff, starting with the intercooler, bov, wastegate, turbo timer, and piping. And save the turbo itself for last, because the standard turbo aint too bad.
The only thing I suggest you do when you get the motor, is to change the fluids and the clutch. You could upgrade the radiator with a Fluidyne and get a Flex-a-Lite electric fan to get even more hp. My friend did all of the above and is pushing 640hp at the rear wheels. He also put in a limited slip rear diff. to prevent wheel spin.

Hope this helps! Happy Hunting!!! :)
Good choice on car!!!
 
i kno nothing about motor or nething, but I really gotta agree with you on the Honda and Acura statement. There’s too many of them around, there FF’s and a buncha other reasons. Like you I’ve become a really big fan of the ’97 240sx, I don’t like the fastback at all. Okay I have sum questions (I’m gonna be honest, I know **** about the engine and internal stuff):
1- Wut is SR20DET? I kno it’s a engine but I constantly hear about it, y is it so popular:
2- What’s KA motor?
3- I was reading toyo’s reply, the 240sx come stock with a turbo?
 
Yeah. A Mini would own a Ka in my opinion. As for the SR20DETT, I can't say anything bad about it. If you want it to, it can pump out alot of HP. Otherwise, its still an awesome engine.

I think he means the KA engine which is the base level 240sx motor. If you couldn't allready tell, I am a huge Nissan fan (see avatar), and I am tired of stupid hondas trying to talk s**t.

Silvias rule!!!!:D ;)
 
Yeah, Silvias rock. But to be honest, I'm more of a Mazda fan, and since I may be buying an FD, it just makes me more go'gettm for Mazda's. But yeah, SR20DETT's rock. Hence my AIM Sn. (SR20DETT Pwnage).
 
ok i have no idea what those Honda guys are talking about..a stock DX beating a 240? im sorry i just need to laugh. Im an owner of a 1998 240sx SE...and as an owner i can tell you..that the tuning of the sr20 and ka24 engine is can still produce 500rwhp and still be realiable..rather than a 500hp b16..that can blow up after one hard run. the SR20DET is a mechanical god on its own. Circuit/course/drift racing you want the sr20det..because the power band on the sr20 is tuned for that sort of driving. If you just wana drag, the ka24de is your best choice. Because the KA is actually a truck engine..and its TQ potential outmatches the SR20, with little tuning and a turbo kit from XS engineering. you can be putting out +400rwhp running low to mid 11s on street tires. the 5 speed on the KA is good for 500hp, and you can always buy a gear kit to strengthen it. The 5 speed tranny on the s14 SR is also good for 500hp, and you can change the ratios with a gear kit from nismo..or get it strengthened. the 6 speed from the s15 is the weaker of the trannies..because what they basicly did was just slap on another gear without messing around with the other 5. If you want more info on the 240sx/silvia go to 240sx.org

I dont know if thats a typo or not Xzift, but the SR20 was not Twin Turbo. And if you are refering to a twin turbo tuned SR20..it wouldnt put down as much power as it would single turbo..since two sequential turbos over 1 exhaust manifold would indeed put far to much restriction on the exhaust flow..making it an unefficient powerhouse. its possible..but not very smart in my opinion.

some other ones i cant name off the top of my head

Nissan X-Trail SR20VET w/ VVT
 
The KA24DE comes stock with the American 240SX. The SR20DET comes stock in the Japanese Silvia. The American KA, should not be used for a couple of reasons. It is heavier due to an extremely oversized block, it has a lower rpm capability, and in order to turbo it correctly you have to tear apart the block and build up the connecting rods, the pistons, the rings, and probably polish the head. Since the SR20DET is already prepared for turbos, it is an ideal candidate for swapping. Yes, the CA18DET, which was the non-option stock engine for the S13, has a higher rpm rating, the lack of displacement is where it loses hp. It does have a cast iron block tho, where as the SR20DET's is part aluminum. I wouldn't keep the KA for more then you have to, try and go SR asap.

If you need some quick hp, search ebay for some cheap headers, cold air intake, and a bomb muffler. Then go to a local Meinike or other Muffler shop and have them sell you some piping that is 2.5" diameter for the header to the muffler. Get rid of the cat. and get an O2Simulator off ebay if you need to have an O2 sensor after your cat. Other than that, don't do crap to the KA, it's just a money drainer.

If you really wanna go risque on your 240, search around ebay for an RB25DET from an R32 or an R33. They will fit in any 240 and have incredible hp. No Honda will touch you then. Make sure to get the ECU and tranny. There will be some minor modification needed in the engine bay and under the car to get it to fit, but it's well worth it. You can usually pick up an RB25 for bout 3-6 grand, depending on where u get it.

If you're having problems stopping your newfound beast of a car, find a 300ZX in a junkyard and swap out the wheel hubs all around your car for the 300's. It will be a bolt pattern change, but for bigger brakes and better calipers, its well worth it. After that, shoot to ease the pain on your tranny, with a carbon fiber driveshaft. If you need anymore help, just give me a PM. Hope you have some good luck out there.
 
BTW, my friend did the cheap hp upgrade I mentioned above on his '97 Honda Civic DX. He got a cold air, header, O2Simulator, 2.5" piping, and a Bomb muffler. He also got 75 hp out of it at the wheels. I think it's worth it.

DID I SEE SR20DETT? THAT I MY DREAM COME TRUE!!! I've never seen a SR20DETT before.. only a SR20DET.. but SR20DETT!!! :D
 
I wouldn't double turbo an SR20 for one reason, it takes my pressure to spool them, therefore they won't kick in till higher rpms, thus there won't be as even spread of hp.
 
hey thanks toyomatt84, thats some very good info there, we'll im saving money right now, so when i get my 240sx, i will make it fast. but i want to drag race and fix up the KA24 because if i blow the KA24, it will be at the junk yard for cheap, they dont have SR20DET stuff, plus SR20DET stuff cost alot, and im kind of poor, i just want to make a cheap but fast KA24 motor and kill all the honda and acura boys, i love the SR20DET but cant really afford everything, so i might as well get the stock KA24 and fix that **** up and get a turbo and spank drag racers, then when i save enough money for a SR20DET, then i will get that, but thanks for all the information, it really help me out more, and it gets me more excite about getting a 240sx even more, but i like to get the 89 to 94 coupe, so then i can convert it to S13, i love S13, and i like the S14 and S15 and RPS13, but i cant afford the newer model, only the cheap old ones, but im always dreaming of what to do with my money for the 240sx.
 
cool ...good choice...when you do get your 240...make sure you know that its slow stock...lol if you need some help with the 240 hit me up..have fun looking for a coupe..:P
 
i just picked up my 91 240sx fastback on saturday, and it IS fast with the stock american KA. i can go from 80 to 110 in about 7 seconds. if thats slow, then id like to see fast O_O!!

but yeah, i'm planning to swap in an SR20DET by the end of summer (hopefully)...its a really good power upgrade. and im not even going for power, im all about drift. my BONE stock 240sx fastback pulls my friend's LS VTEC powered civic coupe by about 2 car lengths in a quarter mile...so i think my car is pretty quick...hell im not complaining about it =D!!

are you sure it pulls the LS Vtec two cars, because my cousin's 91 integra LS-VTEC kills an eclipse GSX fix up, Camaro Z28, and a prelude H22 180 shot NOS, i dont know if a 240sx can do that with stock, because the 240sx runs 16s on the 1/4 mile STOCK, i think it runs 16 or slower. well thats what i see in my eyes, so i dont know about you.
 
I don't think your cousin's LS-VTEC is stock. Because it isn't able to do so stock. But, other than that, I wish you the best of luck Night on ur 240. :)
