KA24de 200hp?

[dmansc88]

i have a 93 240SX with KA24DE engine. I pulled up to a stop light next to an '05 FORD GT (midnightblue, white racing stripes) and i got absolutly raped. i wasnt expecting to even for him to bother with me but i though, what the hell? and when i finally caught up at the next stoplight i realized i need more horsepower, and was wondering what a cheap and easy (if at all possible) get get it up to 200+ hp????

ps. that car has some ungodly 500 hp and an ungodly sound and ungodly speed

N2O, cheapest bang for your buck. Get a wet kit to be safe on your motor.

[dmansc88]

what brand would you recomend for that?

[9240sx]

NOS makes a nice kit.

[Ni2s4s0aSnX]

Cheap? Not gonna happen. If you want 200 horsepower on the 240sx, you're going to have to spend some money. Nitrous is not the way to go. A nitrous kit will cost you at least $500, and a nitrous refill is at least $100. Nitrous is just temporary horsepower, it will end up costing a lot more to have nitrous then to just spend the money now.

[RedHatchback]

Lets see....131 whp + a 75 shot of juice that cost 581 for a full wet kit + $2 a pound per 10lb bottle......I think your 100 bones a refill is a little off...maybe after 7 nice,full runs with 1 10lb bottle than he can go spend another $20 for another 5-7 runs. I deal with N2O everyday.....this is the formula for nitrous usage..... .8lbs N2O x 10 seconds = 100hp. So 1 full bottle will be enough for more than a couple Mustang GTs

Don't use nitrous, do it right. You can throw a turbo on a stock KA very easily if all you want is straight line performance. Much safer for your internals, and you don't have to refill it. Way cheaper in the long run, too.

[Ni2s4s0aSnX]

Yes, you probably don't want to use nitrous right away. But whoever posted last, you are wrong as well. You shouldn't just throw a turbo on as your first mod, because that would actually be worse that nitrous, your transmission wouldn't be ably to handle the power without modification, and a turbo would require a bigger exhaust and other various mods to get the most horsepower.

[JimmyMethod]

If you want another 70 Horses, just stick a V-tec sticker on. Depending on your other mods you could make anywhere from 70 to 110 more on stock internals.

[naed240sx]

are you talking about the ford gt or ford mustang gt. Because they are VERY different cars. One has around 300 hp, the other has 550. the GT is a very rare and expensive exotic. It would be amazing if you actually saw one.

Oy, the stupidity of the internet.

People have gone up to like 600whp on the stock KA transmission, and a LOT are running 240ish whp on it, so nothing is breaking there. Also, while it would require more mods to get the MOST horsepower, so would nitrous. You do realize that japanese silvia/180sx/200sxes came with the same stock exaust system as 240s, right? For the price of a nitrous kit, including a bottle and fill and all related hardware, you could easily cobble together a turbo setup and have more power and have it be more reliable.

[4gotn1]

but unlike the silvia/180sx the 240 comes with our blessed ka. not the sr20 or ca18. which are smaller motors. sure people have laid down 600rwhp, but how long will the transmission hold it? how good is his transmission? does it leak oil, grind gears...etc. not to mention that he would have to pull it out to put a clutch in anyways. cus i highly doubt a stock clutch taking 200whp without protesting.

so even if the exhaust system is the same. the motors are not. the ka being about 400cc's larger, would require a larger pipe for n/a and even bigger for a turbo application, so that the motor could breathe properly. turbo would be the best way to get over 200whp. unless you want to stay na. it all comes down to how you wish to make the power.

If your stock clutch isn't going to handle 200whp, it isn't going to handle a 75 or 100 shot. As for how long it's been lasting, I'll put it this way: I've never heard of a KA transmission breaking from too much power.

[1991S13]

Just give up 4gotn1, lol.

The KA transmission is the same thing as the SR transmission, so if a SR can stand up to 200+hp on a regular basis, why couldn't one on a KA?

The clutch may break eventually, but it takes a monkey brain and a weekend afternoon to change it, so don't worry about it.

After reading the KA-T forums for, well, a long time, I've never heard of that either. I think the ring lands or the rods will crap the bed long before the transmission.

[Bigvinnie]

I hate it when people use the word cheap. Performance isn't cheap, and if it is it isn't that effective. The highest power you will see from your KA is about 200~210 CHP (180~190whp) at the most, with bolt on mods, cams and an ecu program with the stock internals of your 9.6CR. NOS is the most effective route for quick and easy HP, but those NOS tanks start to add up in price once you go through a few of them.

[tiger]

The transmission in the SR20 is the same one in the KA24DE... ;yeah i'd say the transmission can handle some decent horesepower.

You are not even gonna get that high, I say 160whp with bolt ons. Some forms of performance can be cheap... compared to others. 200whp in a turbo KA is going to be cheap compared to 200whp in a NA KA.

Don't use nitrous, do it right. You can throw a turbo on a stock KA very easily if all you want is straight line performance. Much safer for your internals, and you don't have to refill it. Way cheaper in the long run, too.

"Do it right" I bet pro mod nitrous guys would kick you in the nuts for saying that. Nitrous and forced induction are equals as far as WHP goes. I just think that turbo would be more fun and economical in the long run becuase its there EVERY time you hit the gas, not just when you arm it and have a the bottle open etc etc...

In stock form the SR produces around 185whp and the CA is around 150whp if you just use bolt ons with a KA you can have more WHP and torque that a imported CA18DET. Also 600whp and 200whp should not even compared, that is like saying my "I got 300 degree water poured on me and I got 100 degree water poured on me". WTF? leak oil? grind gears? My transmission does both of those in stock form. Exhaust piping size has nothing to do with price and there is no way you can make 200whp in a KA if you need nico to ask how.

Nitrous and turbo do the same thing. They make a bigger explosion by introducing more oxygen to the combustion chamber. If your motor can take 50hp with nitrous, it can take 50hp with turbo. They take simlar supporting mods (like more fuel). Pick one. Nitrous will run you 300-1000, turbo will run 800-3500.

[zippitta]

I couldnt have said it better myself. Both the turbo and the nitrous do the same exact thing...put more oxygen in the engines. So either way would work. I save and do the turbo...mcuh more fun.

Nitrous goes from normal engine to a "full boost" condition instantaneously. That's horrendous for your engine. Cylinder temperatures make an incredibly rapid spike, and metal can only dissipate heat so fast. That's why nitrous is very prone to frying piston rings and burning valves. Turbochargers let things on far less abruptly, since as you go from say 25% throttle to 100% throttle the turbo gradually picks up speed, so each combustion cycle gets hotter and hotter until you get to full boost, which is WAY easier on your engine.

You have to learn somewhere.

[Deadrodent]

well my transmission already blew up. coincidentally i'm taking manual transmissions at wyotech right now. the crappy thing? my transmission blew up on the freeway so i had to tow it to a local shop...which will cost me major $$$ to fix....

[tonynalli]

so yall dont think that there is any way to make around 200 hp with a ka w/o nitrous or a turbo. im thinking that it might be possible to come close at least. i mean with the right cams, the right rebuild, the right bore, stroke,engine mamagement, mabey some pullies, complete ignition system, the right head work, some custom manifolds intake, exaust,high compression pistions, gapless rings.and the list can go on. although it would cost you more money to do that and deal with the trial and errors that you have durring a build you could probably pay someone to put a rb26 in your car.never the less. hell most of the things that i just mentioned about head work could be done for just about free, only if you kno how and have the tools. **** a stroker kit can be done for relatively cheap if you have a machine shop near by. (hell i got one of my motors hones, bored, cleaned, and whatever else was done for a few hundred bucks. double it for the modifying the block, ok that would be pretty expensive. pistons would be something along the lines of 300-600, the gap less rings arent that much either. and as far as cams are concerend, jwt makes good products, along with some engine managment, ingition systems arent all that cheap, but you kno i just think that it can be done. and im sure all of the techies will start calculating what i said and call me a dumb *** but...there are plenty of mods or tricks that you can do to the motor while building it to add hp aslo. so....sorry for the long post...and **** after all thats said and done. then put a turbo on it, it would be unbreakable....not really but...

YEA it was definetly the Ford GT with 550. but i live in a rich part of town so its not uncommon to see ferraris LAmborghinis, porshces, vipers, ive seen maseratis, maybachs, and i think 1 ENZO

[Ichi-Go]

You have to learn somewhere.

Some chats will Scooter and Devious would help a lot. And even those guys arent anywhere near 200whp.

I am not saying it cant be done. There are KA's with 300hp its just not very easy, or cheap.

[Kenrik]

You will spend more getting a N/A KA over 200WHP then you would getting a turbo KA over 300WHP it's just not worth it...

[tonynalli]

definatly, but it was asked if you can get a na ka up to 200 hp. for the money that you would spend on building a 200 ka, you could probably build 2 300 hp ka's.

[InsanityInc]

Not really, unless you're talking a junkyard turbo kit and even then it's pushing it. 200whp really isn't that hard. Just rebuild the engine with KAE pistons, throw a header, 3" exhaust and intake on and futz with your cam timing, or do a cam swap. You're looking at under a grand if you do it yourself, and you have the added bonus of not having forced induction.

uhhh i think it would take more thn jus that to make 200./header/exaust/cams/and cam timing would not be enough for 200. mabey like 160-165
